[Q] Wi-Fi Woes

Ok I have a very iritating problem.
My captivate works amazing in all ways... except one. When I'm at home connected to Wifi, within a few mins of me putting the phone down, or even mid use, the wifi will just stop working. The icon still shows it to be connected however no apps are able to actually get internet. A quick pulldown of the quick access menu and tapping wifi off and back on again gets it going great... for another 5 mins. Then the same thing happens.
Its been like this ever since I got the phone, even after flashing different roms. Now i'm running a Linksys Wireless - N router - maybe they're not playing nice?
I dont think its a hardware fault because when I serve wifi, IE the captivate is an infrastructure mode access point for 3g, it stays on consistently and my laptop can tether for 2 hours or more.
Anyone know what might be causing this?
Thanks

When you have wifi on, go to menu settings and 'Wireless and network'. In Wi-Fi settings you can change the Wi-Fi timeout.

Try goin to settings->wireless and networks-> wifi settings (menu key)advanced and set the sleeping policy to never

I've done that...
i *Think* i've fixed it. I was using WPA2 IPK encryption or whatever.. Switched back to the 64 bit crappy WEP. Wifi was on all night and all morning with no cut out.
Might be just another linksys-is-crap situation.

HI, I figured I keep my wifi woes within a singe thread so.
I have an old D Link WBS 2310 router.
I recently got a message from AT&T that I'm near my data limit. This surprised me as my last cycle I barely got near 500mb. Since my bill isn't ready yet, I can't see exactly what it is I'm doing to use so much data.
TO be safe I figured I'd pull out my old router and set it up. After hours of hassle getting it to work on my new computer, I wasn't able to get my Captivate to hook up to it.
My laptop works fine. It gets a fast wifi signal, but my phone just says "Obtaining IP address" for a while and then gives up.
My phone gets wifi at work, at friends', at coffee shops - but not at home.
I've tried this with no encryption, WEP encryption and WPA2 encryption.
Each time my laptop would hook up to the wifi but my phone wouldn't.
I searched some other forums and found similar problems with HTC phones.
Some answers say that D Link sucks. But that answer applies to other brands as well.
Do I need "n" wifi, rather than "g"?
I don't want to buy another router only to find it still doesn't work.
Any help?

part of the IEEE 802.11n standard is backward compatibility with all previous 802.11 standards IIRC, so there should be no need to buy a new n device.
HOWEVER, i am also having issues with my wi-fi and my g capable router. i will meddle around with some phone and router settings to see if i can fix this, this is one area were i can actually be of some use on this forum

Hi. It turned out the wifi was broken on my captivate. I reset it to stock and it's all better. It had been working up to the previous day so I assumed that it was still working. The router goes down intermittently in general, so I've ordered a new one to see what's up.

Hi, I'm back! So after resetting the phone and getting wifi to actually connect (rather than being stuck searching for IP address), I'm now having the exact same problem is the OP. The OP seems to have solved this by switching to WEP. I tried this and it doesn't work. My timeout is set to never. Also, it's the same at home (I replaced my router) as well as at Starbucks and a friends house.
I'm connected, but can't download or sync. It works initially and then stops, and then comes back in briefly and then stops, all the while "connected." Sometimes I can fix it temporarily by turning off wifi and then turning it back on.
SO what's the deal? Is it a hardware problem? Is there some secret magic code?
edit: Just disabled encryption - same problem.

[Q] Anyone still having wifi issues???

I have looked at every thread and forum possible for the past 2 months. My wifes nexus and my own connects to our home wifi for a few minutes then disconnects itself (weather the screen times out or not) and will not reconnect at all. I have tried the wifi fix apps on the market, changed the settings on my router numerous times, factory rest my router and phone, changed roms, and even routers but nothing seems to work. My wife's nexus is stock and not rooted so I have been using hers as a reference thinking it was maybe a rom I was using but she is having the same problem. Any ideas would be greatly appreciated.

I had that problem but as soon as I got to 2.2.1 and/or used a newer Radio version, the problem disappeared...
Although, N1s are still very picky on routers...try with another router and check if it keeps the connection alive.
Also check your router settings to see if they're optimal (try having no password set and see if it keeps the connection...if it does then it might be a problem with the N1 not crypting information well or so)
You could also try updating the router's firmware.
Make sure your wifi policy is set to "Never" (go in wifi settings the press Menu and click on settings)
Last thing you could try is manually set an IP address + gateway + netmask in the wifi settings as well as setting your N1's mac address to that same IP address in the router...
If nothing works then, I'm completely out of solutions

I just got on to look at some of the settings with my router when I noticed that some times when my phone says I am connected to the wifi there is no IP address assigned to the phone. Under connected devices it says "android device" but with no ip address associated with it...

I still have the problem
I still have the problem. I have pretty much given up on it. I have heard that if you increase the minimum CPU speed a little, it will help. I'm not willing to do that as it will undoubtedly waste more battery.
I have changed the wifi sleep policy back to "when screen turns off", because having it on "never" would make the phone think it's connected..when it isn't..leading to hours of no email notifications and such. But I can't imagine how frustrating this must be for people who don't have a data plan or some other similar situation.
I'm thinking about getting a Wireless N router (I have a G right now) and seeing if that helps. But even if I was to get one, I don't have much money to spare so I'd probably get the cheapest N routers, around 30-50 dollars..and I don't know if those are any good...or if there really isn't any difference between the high priced and low priced ones.

I said this in another thread, but I'll say it here.
I tried all of the things everyone could suggest and none of them worked. When I heard Broadcom updated the driver and CyanogenMod put it into his nightlies, I bit the bullet, unlocked my bootloader and installed CM6 and it changed NOTHING. So I went out and bought a new router: Cisco E3000. It works great. So I guess it was a bad combination of phone and router. I had to spend hundreds of dollars. Really ****ing pissed me off. But I wasn't going to buy a cheaper router without dual channel wireless N.

Nexus has N connectivity but only on one band (2.4Ghz) and I don't think the technology matter (heck, I'm still on 802.11b ) it's really more of a phone/router combination problem...
I did actually test on my VERY CHEAP spare 802.11g router (DLink --> do not buy their products) and the connection did NOT stay...that was back when I was on stock FRG83 though...I should try again on Cyanogen but I'm wayyy too lazy ^^
btw, I really don't get why people always unlock when they wanna flash a rom....heck, keep your warranty!! there is an easy way of doing it without unlocking...meh
PS: I have a 50MB data plan (technically, I didn't buy a data plan, it came free) so I AM a heavy wifi user and it was such a pissoff to find out that my new Nexus One couldn't connect to Wifi and keep the connection alive...now I'm damn happy that it works after all that fiddling ^^
@sigep: try to assign a manual ip to your N1's mac addres...or update firmware, it definitely looks like a router problem...

The root without unlocking method wasn't too tested when I unlocked my bootloader.
I have made two swaps with no problems since.

Oh kay sorry then
Although all the new wikis and todos should emphasize on the locked bootloader methods to avoid voiding warranties...although I admit fastboot is always noobproof but I digress ^^

I've been testing several routers from different brands, and the only one that seems to work fine with mi Nexus One is the Linksys/Cisco WAG160N (802.11n, but 2.4 GHz only). However this one has other issues of its own, like not being able to connect to mapped ports after two days up and running (not even from the LAN). The N1 works fine, thought, it doesn't disconnect overnight.
I've also tried an SMC (SMC SMC7904WBRA-N, I think). This one is really bad, the router freezes after only two days of use, the lights freeze and it stops working altogether. I returned it after a week.
I'm currently using a Sitecom (300N WL-348). With this one the N1 WiFi is dropped over night, and the connection to this AP is disabled. I'm still testing if moving to a less crowded channel could fix that. I hope it does, since this router seems to have a more stable firmware that the Linksys/Cisco, same WiFi coverage (which is quite good), and even better WiFi performance. Not all is good, though, DSL performance is worse.
In the past I used Netgear routers. The firmware was stable as rock, but the hardware not so much and after a year of use they are very prone to failing. No idea if newer models are any better in this regard, they are impossible to find, so I don't think this has improved.
Since I have DSL at home, I'm looking at routers with DSL modem built in, so I don't have to have two devices (DSL modem and wireless router).

From my observarions - Nexus will disconnect from WiFi when the IP it has is lost and the network doesn't supply IP on time. After 1 or 2 IP assignment timeouts, it will skip the network and refuse to connect.
Every router I've connected to that supplied IP on time, even when revoked every X min, didn't cause disconnects.
Of course, WiFi on sleep set to "Never".

Success! Last night I updated the firmware of the Sitecom router, and changed the WiFi channels (it's set to use wide channel, so it uses two channels). This morning the N1 had still a solid WiFi connection and over night it updated all services just fine (weather, Facebook, email).

I've been using the Sitecom router since my last post with no issues. Then last friday arrived a small update that broke WiFi. On Saturday arrived the bigger update to Android 2.2.1 but the problem with WiFi remains. Before 2.2.1 Wifi has been working fine every day at home and work, now with 2.2.1 it's broken at home and work.
Are we moving forward? If Gingerbread doesn't fix this problem I'll have to do something about it: try cooked ROMs or even getting another phone . Currently my N1 keeps disabling my access points all the time.

[Q] Samsung Galaxy S Wi-Fi problem

I have a Samsung Galaxy S Vibrant device and a strange Wi-Fi connection problem.
It seems that the WiFi conneciton is being lost intermitently with no apparent reason. I ping the device, most of the time there is a 'Request timed out' and only sometimes a 'Reply from <address>'.
On the device side the connection behaves erratically as well, sometimes there is connection but most of the times there isn't. The strange thing is that under device's Settings->Wireless and network->wi-Fi settings the connection's status is "Connected" all of the time, signal strength is excellent, link speed is 54Mbps.
I had this issue on a native 2.1 Samsung Galaxy S Vibrant install, then decided to flash a custom 2.2 ROM hoping to end the mistery. The new custom ROM is an Axura21VE.zip and the WiFi connection problem is exaclty the same as before.
Does anyone have the same WIFi issue as I have? And yes, I did a search before posting this. In fact, I searched for several weeks and saw many SGS Wi-Fi problems being reported but either they are different or they are similar to mine with no solution. Since I need a stable Internet connection on the device for app development, next logical step would be looking at reverse USB tethering. Yet decided to post here before giving up on Wi-Fi.
For the record, the Wi-Fi acces point is under my control, i have a ASUS P5B-MX/WiFi i946GZ motherboard, windows XP sp3. I tried, I think,
every possible combination of Wi-Fi settings available. The only client device I have at home is SGS. At the office network, SGS is having the same
Wi-Fi issues, while a HTC Desire and many laptops don't.

here is what I just found out: if I do a constant ping form the device to google.com for example, then the conenciton is maintained all right. So, should I constantly ping something to maintain a decent connection? Is there a setting or something in Android OS I am missing?

I had this exact problem - changed my router and it works perfect now. Really weird and not an ideal solution but worked for me so far (touch wood!). Try playing about with your wifi config maybe, change encryption, channel etc. Good luck.

Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release. The device says I'm connected to the network but I can't get any internet access. I tried reflashing my official firmware DXJPA, but I still no joy. I'm not really sure what to do.

YES... i have been searching for days. I feel I may have a similar issue. im connected, speed good, IP there.. no data, browser just hangs. seems to happen less in stock. (Rogers captivate, P10.1) also WiFi manager reads my WiFi channel off by 2!! so im set to use ch 9 on the router and WiFi manager on the captivate says its broadcasting on ch 7?? any ideas? ping to infinity??
side note: this happens on all routers and all roms. other galaxys on my network read proper ch... GF's Iphone see the right channel?? HELP..

I'm also having these problems, reposting my reply from another forum:
Just wanted to chime in that I am also having these problems with my samsung vibrant. Seems to only happen from my work router but happens very consistently. Wifi will work immediately after setting it up but after a short time period will stop working completely. It will say it is still on wifi but will in fact have no access to the local network or the internet. Stopping/restarting the wifi connection doesn't fix it. The router has to be manually 'forgotten' and then re-added for it to begin working again. (Update: sometimes this does not work either, in fact).
This is with a 2wire modem (standard issue by at&t) using WEP security in 802.11b/g mode.
Some people recommended switching from 201.11b/g to pure 201.11g. I tried this with no luck. It was also recommended to try to app 'wifi fixer'. This also did nothing to solve the problem. Given that it is my work router, I don't want to go changing the encryption and other crazy things as I'm not the only person using this router and it would break the connection for others.
MRSizzle in another thread (which xda isn't allowing my to link to) seemed to accurately describe the problem as such:
"It appears to be a driver issue with the Samsung base OS drivers in the phone. Possibly sleep policy is not operating correctly and the wifi radio is being disabled by the hardware and is not being controlled correctly by the software so the WiFI icon still appeers to indicate the phone is connected. Also the wifi signal is not being correctly reported. the signal appears to be attenuated more than it really is."
This description would line up with the OP's reports that repeated pinging will keep the connection alive.

Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release
ASK DARKY its his rom and will know more .

Anyone figure this out? I'm trying to use the Web Desktop app but can't because I can't even establish a connection with my phone!

Hi friends,
I have similar problem, but at first I easilly connected to Internet, but now I can connect to my WI-FI but no internet connection. I am not sure but maybe this has occur after updating to Android 2.2.
Any suggestion?
Thanks in advance.

explanation and apology
I was wrong in my assumption that it's an Android device problem. The problem was in the Asus motherboards embedded Wi-Fi access point. I bought a separate Wi-Fi router and now everything works like a charm.

Wifi signal drops to "poor" and won't connect with 2014 moto x

I just received my gen 2 moto x last night and am having trouble connecting to Wifi at work. It connects to my home network and one of my work networks just fine, but when I try to connect to the work network I need it to connect to the signal strength drops to "poor" as soon as I press connect. My home network and work network both are password protected. I've verified the password and have the same connection settings as my friend's gen 1 moto x, which connects properly. The work network has excellent signal at all times when I am not trying to connect to it. It just keeps cycling from "connecting" to "saved."
Has anyone else experienced this or know a workaround? I found this but this is for a gen 1 (I'm not sure if that would help) but I'm not rooted so I don't have access to phase 2 authentication. http://forum.xda-developers.com/moto-x/moto-x-qa/wifi-signal-drops-trying-to-connect-t2872241
Thanks,

Exact same problem. Fine at home and everywhere else. Spent a couple hours this week on the phone with Moto. They keep saying it's the network, yet everyone else is on it. They say update firmware and open MAC. Both of which are done.
This is the message in the Access point every 3 seconds when my phone is trying to connect...
"Client Deauthenticated: MACAddress:9c:d9:17:a1:c8:51 Base Radio MAC:b8:62:1f:ad:5e:90 Slot: 0 User Name: unknown Ip Address: unknown Reason:Unspecified ReasonCode: 1"

My wife's phone drops WiFi in favor of 4G LTE at home. I have to turn off data to connect to WiFi but it eventually drops the WiFi. I'm still waiting on my pure edition so I'm not sure if its just her phone or if its a common problem.

This!
I have this problem all the time ON multiple networks, its very frustrating

Mines will disconnect from my 5ghz when the screen goes off and reconnects when turned on, works fine on 2.4ghz. I have a Nighthawk ac1900 so the phone is definitely the problem.

This is related to 802.1X, We have it implemented Radius and 802.1X at work and it doesnt connect. But the same AP has a guest SSID which has no protection and a separate vlan which has access only to internet and it works fine.

Sounds like this could be my problem. We have 4 networks we can login to, but they are all broadcast from the same access point. One says "secured with 802.1x" and is for laptops, two say "secured with WPA/WPA2" and are for cell phones/other, and the final is unsecured. I can only connect to the unsecured network.
So does it sound like it's the phone that's refusing the network, the network is refusing the phone for something the phone is sending back to it, or the network is refusing the phone for another reason?

I'm having this same issue. 1st Gen Moto X sitting right next to 2nd Gen, and the 1st Gen is connected while the 2nd Gen can't.

I'm having the exact same issue. It appears the problem is that older Cisco firmware doesnt support 802.11w, which is what the moto x 2014 uses by default. Here is a thread where a moto rep explains it to Cisco - https://supportforums.cisco.com/discussion/12331486/connectivity-issues-cisco-controllers-and-pmf-enabled-moto-x-gen-2

My girlfriend and I have this phone and we had a similar problem. It would connect/reconnect like a billion times before staying connected on our home network but connect fine on other networks. I tried several solutions but the one that worked was changing the channel on the router. I live in an apartment building and there are a lot of WiFi networks around me so I figured that might be causing some interference. I changed my channel from 6 to auto (it automatically jumped to 11) and now it connects instantly and is solid. What's weird is I tried channels recommended by WiFi analyzer and my other devices would connect just fine but the Moto X's couldn't even see the network in the list when it was on a lot of channels like 12, 13, and 14.
Seems like a weird WiFi radio firmware bug to me.

Is there a client side fix for this?
I just ran into the problem at my work. It is a major hospital. They are not going upgrade their cisco firmware so a couple of people's personal phones are able to connect to the network.

WiFi in general is bad on the X2014 and I am reading the same in the Droid Turbo forums.

What!? Really?

I've not had a single issue with WiFi connectivity. I'm an IT professional so heavily reliant on WiFi.

I never had a WiFi problem with the Moto X 2014 until today at work. It wouldn't connect to a few different clients Wireless APs. At the first client site I power cycled the phone and WiFi still wouldn't connect. I then went to another client site and once again it would no longer connect. I power cycled again and this time it connected just fine albeit Bluetooth was acting funny and not connecting to the Moto 360. After cycling Bluetooth off and on again the 360 finally connected. Not sure if this is an actual issue or just dumb luck. I wonder if anyone that was having WiFi issues with this phone also has a Moto 360 connected via Bluetooth?

I don't own a 360 and my bluetooth is normally switched off unless I'm streaming music at home.

I know none of what I am about to write will solve anyone's issue but sharing my experiences mught help understand you're not alone. I wander between as many as a dozen different wifi networks daily. I manager a 63 room hotel on 7.5 acres where we are currently running EnGenius EAP350 AP's broadcasting in 2.4mhz band ONLY using .11bgn. I set the entire network to use one SSID so roaming is, in theory, problem free. My XT1095 has not had any issues at all here on property.
I also have my personal network in the lobby and main building under 2.4/5/.11AC side by side with out guest network. No issues bouncing around. I honestly expected issues but have found none.
There is one issue I have found in Android in general which can happen randomly, or I have not been able to induce the behavior only recognize it. Occasionally when I move from one building to another Android (ICS forward for sure) will forget which actual AP it's after and just hang. My solution is to tell the device to forget that node then once forgotten the network, of course, shows up in the list. I then select it and boom we're back in business.
I do have issues when I visit a network at say, the grocery store which requires accepting an EULA...the device simply will hang Wifi wize, even when I delete and reconnect I won't get the note to open the authorization page. I end up just killing wifi and going with LTE.
I get the same behaviors from all my phones ICS though Kitkat, don't have Lollipop yet darn it!!
I have long been frustrated with this weirdism from Android but have reached a point of M.A.D. with my devices but never found a solution.
I have noted I have the most issues by far with Cisco/Linksys devices. It has been almost assured that if I have an issue it's one of those routers running an older firmware version (amazing how many AP/routers use default password settings...I mean, really???)
Not 100% sure it's a firmware only issue but I do think it's some common bit of hardware in an AP/Router which can go spastic for some reason preventing Android from figuring out how to remain or get connected. I even had one of the EnGenius AP's go nuts, a fast swap with a freshly configured AP resolves but, again, still does not identify or solve the problem
I also sense there is some oddness deep in the bowels of Android's wifi/networking subsystem which just was never written correctly and may never be fixed.
Last I run and app called Wifi Analyzer by Kevin Yuan, it helps me a GREAT deal because I can target a specific AP/node to connect with. Android versions often defeat this by not remaining connected to that desired target AP and switching to something else. Here is where I think some of the issues with wifi connectivity live...Google MUST spend some time refining their wifi subsystem.
No matter this is a Very frustrating issue when it happens. My best solution has always been to forget the current connection then reconnect with it again once it reappears. Better yet use Wifi Analyzer or similar app to target a specific AP/node and connect/forget from inside the app, that really does seem to help, mostly...sigh, I know, sorry...

This WiFi issue is really aggravating. I have tried so many things:
1. Rebooting Router
2. Powering Off/On Phone
3. Turning WiFi Radio Off/On
4. Resetting Phone Cache Partition
5. Using WiFi analyzer and setting my router to various channels manually
6. Changing Router SSID
7. Forgetting SSID on phone and re-adding it
8. Verifying MAC Filtering is not enabled
9. Enabling MAC filtering and specifically allowing phone MAC address
10. Disabling "Avoid Poor Connections" in WiFi settings
11. Manually setting WiFi frequency band to 2.4ghz in phone settings
12. Disabling "WiFi Optimization" in phone settings
23. Changing WiFi direct and BT phone names (yeah, a big stretch, but I read somewhere that this worked)
24. Installed updated firmware on my ASUS RT-N12D1 (3.0.0.d.376_3602)
25. Disabled WPS on router
26. Switched router between Auto, Legacy and N-Only
27. Disabled Authentication and Encryption on router, just an "Open" connection.
After all of this, the phone still has WiFi connectivity issues. Sometimes after a phone power cycle it will connect to WiFi, but never for very long. Every other device I have connects to the WiFi without issues. I just got the Moto X a few days ago (AT&T version) and this is the first time I have ever had a device with WiFi connectivity issues like this. Very aggravating. There is clearly something wrong with either the hardware, or software on the phone.
There are some other oddities. When it won't connect to WiFi, there is something strange with the phone. Its not like it just can't connect or stay connected to WiFi, but somehow it seems like the WiFi is in a stalled state. Sometimes it won't show any WiFi networks and just says "Searching for WiFi networks..." until I turn off wifi and turn back on again. Then as soon as it turns back on, it will show the nearby SSID's, and try to auto-connect to my router, but after a few seconds it shows "Disabled" under the SSID. Then after a few seconds the disabled goes away, and it just shows the SSID name. It also won't let me change the WiFi Direct phone name while the WiFi is in this state, it gives me an error saying "Failed to rename device", followed by "Group Creation Failed". However, when I am actually connected to WiFi, I can rename the WiFi direct name just fine. So its not just simply an issue with bad radio signal or something, but something more serious, like the WiFi state is hung or something. If I can't resolve this in another day or two, I am going to have to return the phone, and hopefully a replacement will work. If not, I might have to get something other than a MotoX because I can't not have WiFi while at home and work.

I found a way that seems to work to connect to WiFi. To clear, this isn't a fix for the data-sync issue that some people are having, or poor signal, but the issue where you can't connect to an SSID, and there is no error or anything.
1. Hold Down Power Button
2. Turn Airplane Mode On
3. Turn Wi-Fi On
4. Connect to SSID
5. Press Power Button down again
6. Turn airplane mode "Off"
I have now tried this several times, and it works everytime. If I turn off Wi-Fi and back on again, it won't connect, until I do the airplane mode trick. I don't know who to give credit for this, I have spent days and hours searching, and I remembered reading that from somebody else, but not sure where, so this is not my fix, I am just posting it here as it seems to work.
This issue is strange, and must be some combination of Android, and Motorola software/hardware/firmware configuration. I hope they get this fixed, but it at least now, this temporary fix will work whenever WiFi is not connecting.

For those of you getting WiFi connectivity problems, it could be related to your router setup. Download an app called InSSIDer and run a scan, then choose a channel that's not being used but make sure it's 5 channels higher or lower. For example, if it detects 3 networks on channels 3, 5 & 6, then you want to choose channel 10 or 11. If it detects one network on channel 6, then you should choose channel 1 or channel 10 or 11.
I noticed issues like this when I bought my Nexus 4 after my iPhone 4. Android devices seem to ship with rubbish WiFi radios.
Like I've mentioned before, I've not experienced a single disconnection with my phone either at home, work, in laws, coffee shops or anywhere else ever. Same with my first gen Moto X.

Mine is slightly different. Now and then, after power cycling or rebooting, it forgets all the WiFi passwords. Not every time. Just now and then.
Also sometimes it's quite fast, some slow. My wife's firs gen is pretty constant.

Galaxy Tab S2 5g wifi troubles

Hi, is this the spot to ask about problems with the stock tablet? If not, I'm sorry. If, so please help!
So, I got a tab s2 for christmas. So far I'm loving it, except it will not stay connected to 5g wireless for long! Sometimes it will kick me out every half hour or so of continuous usage, other times it will kick me every 5 minutes. The connectivity problem seemed at first like I just had to adjust something with my network except that any other device that uses the 5g signal does not have that problem! ALSO, sometimes when it hangs it completely freezes the tablet and I have to do a hard reboot (power and vol down buttons) to make it usable again.
At one point I was in the wifi settings page and saw the wifi toggle go grey. It NEVER reconnected after 3 or 4 reboots! Is there something wrong with this particular tablet or is this some sort software issue?
My router is a netgear r6250 fwiw.

Try changing channels on the router, you may have interference on the channels it's using
You can use InSSider to check for channel congestion.

I have been using Netgear Wifi Analytics to figure out my wifi dropping. I have no trouble with signal in the house...None of my other wifi devices are having trouble! As a matter of fact, just a little while ago, while testing the wifi on the tablet, the signal dropped. I pressed the home button then the whole tablet froze again. Instead of hard rebooting it, I decided to leave it alone to try to get it to unfreeze on its own. It did after about a minute...BUT the area near the volume and power buttons are was pretty warm/hot. The battery also lost nearly 8% in that time as well!
Does this particular one I have just simply have a bad wifi switch/modem/antenna?

I have the same issue. SM-T810 keeps dropping wifi connection to my netgear r7000. Both 2g and 5g. None of my other devices have the issue. Seems to occur a lot with chrome or anything else that saturates the wifi link.

I'd suggest getting the tablet replaced. I've disabled the 2.4GHz mode on two of my routers (ASUS AC66U and ASUS TM-AC1900) and my Tab S2 never had any troubles with 5GHz on these routers.
Anyway, no matter what obscure configuration your router might have, it shouldn't cause the whole device to freeze. Unless Samsung seriously screwed something up, even if the wifi driver crashed (in the worst case), the worst that would happen is that Android won't let you turn on the wifi.

I replaced mine yesterday and the new one is just fine!

I called the Samsung help line, described the symptoms and they said it sounded like a hardware fault rather than a software issue - took my reference number back to place of purchase and swapped it over for a new one. The new one has had zero issues, has not disconnected from wireless once or frozen and even just general browsing seems smoother - the first one definitely had some issue with the wifi bit.
This without even rebooting the R7000 router between the last bout of freezing and disconnections with the old tablet this morning and then starting to download all my apps and settings and wireless sync of 2 gig of data for the new tablet without a single hiccup two hours later. So the router or signal are not the issue.

It sucks, but I'm glad I'm not the only one that had issues!
