Galaxy Tab 'forgets' to reconnect to wifi?

I've notice a slight issue with my Tab. Sometimes, when it's been left sleeping for a while it 'forgets' to go back to wifi and stays on 3G connectivity, even though I'm sitting right next to the wlan router. If I check the wifi settings, the network is listed as 'out of range'. If I turn off wifi and then back on again, it connects without any trouble.
Has anyone else noticed this behaviour?

This is most certainly a router issue. The simplest fix is to reserve ip up for the tab and use fixed up settings.
I do this with all my LAN devices anyway because it adds a little security, as well as better interconnectivity.
But really you should investigate the router.

Somehow I doubt that. I'm using DD-WRT running on the classic LinkSys WRT54G, a combo that is widely famed for it reliability. I also have the router set up to serve a fixed IP to the Galaxy Tab, determined by the MAC address of the Tabs wireless interface.
I'm also running quite a few other wifi devices with the router, including three other android devices (G1, milestone, nook), and none of them show the same behavior.

I see... how many of your other devices use a dual band revision n radio? In my experience this can be a headache, even for custom firmware.

None, as far as I know. I'm not entirely sure about my wifes Motorola Milestone, but I'm pretty sure the G1 and the nook use bog standard 802.11g. I think you're right that this might be the problem. Any ideas how to improve that? It's not really a problem, just a slight blemish on the otherwise awesome experience.

This is well known android behavior making wi-fi sleep to preserver battery.
There are some mods to keep it on when sleeping.

Yes, and there's nothing wrong with that. I certainly don't want wifi on all the time, I just want it to reconnect when it wakes up.

Ill look into your router tomorrow, but atm I'd say there wont be much you can do other than force g only on the router. This will stop the tab from sending crc/ plcp overhead on both bands. Crazy as it sounds, the tabs radio is actually interfering with itself in this scenario.

I just replaced my HTC HD2 with the Samsung Galaxy Tab and have the exact same problem. The HD easily picked up my work and home WiFi when I moved between them, but the Tab 'forgets' to reconnect after standby.

I'm having this problem too. Every morning I need to turn off the wifi, then immediately turn it back on, before it will reconnect. This is with an Asus WL520GC running DD-WRT.

Yes, seems to be a router/device compatibility issue.
My tab works fine in my uni network (and it has quite a few dark spots), all of my friend's networks but it intermittingly fails to reconnect to my home wlan. I have a sky router (sagem actually).

I have seen this on various routers before and encountered it again last night.
There is a discussion on the cause here:
http://forum.xda-developers.com/showthread.php?t=839367&highlight=connect+wifi&page=3
It is due to the lease expiring from the access point and the device requesting the old IP with first sending a discovery message.
One work around - not the best - is to reboot the router. Then the Tab seems able to connect. Also I think if you connect ofter to the router you might not see this as the device will ask for a new lease.
Another - from the above referenced post - is to create a DHCP reservation for the Tab. This will ensure it gets the same IP address every time. I made this change to my router - so we will see.
Hope this helps.

Samsung Galaxy tab won't connect to WEP wireless
I am trying to get my Galaxy tab to connect to my HTC HD2 that is set up as a wi-fi hotspot.
My galaxy tab will connect to all WPA/WP2 networks but not the WEP. Please help.

mine does the same on a SMC Gateway (SMC8014WN) aswell as a D-Link Router (DIR-665)

I am going nuts here because of the same problem. Tab worked flawlessly for the last 4 months, found any router and had no wifi problems until recently. I have a D-Link DGL-4500 gaming router, and my dsl modem router also has a wifi connection. I suspect from the new firmware. Mine is a Euro model. I dont know why I upgraded from JK5 to JMG stock firmware, and wifi issues started. D-link's logs reports that it receives a deauth from the device and the connection ends... and never revives. Sometimes it happens 3-4 times in an hour, sometimes it stays connected for hours. I tried everything, static IP, delete dhcp list, etc. I have reset the device twice to factory defaults. Even then it disconnected the first minute I turned it on and set the wifi. So it should be a firmware issue. I realize that the wifi signal is also weaker now compared to the previous firmware. Congrats SAMSUNG! The Tab is consuming my data plan even when I am home. And I wonder how wifi only Tab is going to handle this problem. DOES ANYONE KNOW IF WE CAN DOWNGRADE FROM JMG?? Help is appreciated.

my tab does the same thing (so does my x10). But when I open my browser, or anything that needs wifi, it reconnects automatically, however the browser usually needs to be refreshed (retry).

exactly the same behaviour. Every morning, I'm connected to my router but nothing works. Turn-OFF->ON and it works again

I should have noticed Roto's entering line. See: http://forum.xda-developers.com/showthread.php?t=939360.
Since JMG has wifi isuues, I jumped onto JMI !

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.

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.

WiFi dropping randomly

None of my devices has ever had dropping problems with the WiFi (iPhone, iPad, S6 Edge+, notebook and a wifi extender). But since I bought the S2, it is randomly dropping connection, with no pattern.

Which model did you buy?

SM-T719
It's the latest 8" with qualcomm

Yes I'm having the same issue in the T713 model but not in the T813 model, both are th Qualcomm model

Im having the same issue with mine. I called samsung support and they were no help.

Just replaced my SM-T810 with a SM-T813, and ran in same wifi drop issue. My girlfriend and her SM-T813 ran in the same issue too. It happen randomly from 3-4 times per hour to one time in 2 hours. I foud it only occurs on 2.4ghz network connected in N. It happen to me on 3 differents routers, DIR-868L REV B 2.04, DIR-868L Advanded Tomato, DIR-628, and Asus RT-AC68U stock with latest firmware. If i configure the 2.4ghz band to G only, no issue, also, the 5ghz band got no issues at all. Hope this help your issues while waiting for a fix from Samsung.

Thanks for the tip. I can confirm that 5ghz wifi works perfectly. Hopefully samsung will fix soon.

Valid information, ndompierre!!
I´m situated in Germany and bought a S2 8.0 (SM-T710, Android 5.0.2) last week.
One of my use cases is watching movies which are stored on my NAS. With my "old" Nexus 7 (2013) everything worked like a charm.
But with the S2 I ran into the issue that the movies stucked once in a while.
At first I thought it had something to do with the apps I am using, BSPlayer and MX Player Pro (which work fine with the Nexus).
I even downloaded VLC Player but the same behaviour occured.
Then I downloaded the movie locally to my Tab and deactivated WiFi. Bingo..played without any hiccup. Proof enough that everything is fine with the apps.
So I googled a bit and came across this WiFi issue others also have. After I followed your proposal and changed the 2.4GHz band in my router from option "802.11n+b+g" to "802.11b+g" everything works fine again. No dropout during the whole streamed movie.
So I hope, too, that Samsung will come up with a WiFi fix soon.

Interesting. I've noticed that since updating to MM, my T810 seems to frequently switch to my other wifi networks on me. My preferred SSID is 2.4GHz N mode. I never catch it happening when I'm using the tablet, but after going to sleep and waking it up it literally seems always to be on the "wrong" network if I've previously switched it to the "right" one (not sure if it hops off the other 2.4GHz ones as well). I'll stick wiht 5GHz for the time being!

Saw Spotify dropping out a few times this weekend while connected to a wifi Hotspot. Haven't had a chance to test it at home yet. T817W model running Marshmallow.

I bought the T719 LTE 8.0 inch Version last week and also hab wifi connection problems, but only when in airplane mode. My Router is am fritzbox 7490 at 5ghz. Currently without any reason the wifi connection is stable. When in LTE mode the wifi was always stable.

I have the same problem too. (T719 LTE model) I was wondering would the radio mode consume battery faster instead of airplane mode?
P.S. I still have problem but i am on airplane mode. Have not tried yet radio mode

disconnecting wifi
I have the t819 bought it last week constantly dropping wifi had the s3 tablet before never happened also have ipad and does not happen. Sent samsung an email but still waiting for reply

My T813 does this, but only on battery when optimization is on. When it's on the charger, or I turn power optimization off, it stays connected pretty solidly. I suspect a fault in the power management.
It is kind of annoying, as I have some clients that have to be restarted every time the network drops.

How do you turn optimization off? Battery optimization can be turned off on my tablet, but it has to be done app by app (one at a time)

Same problem started to happen recently with my phone but only with 5GHz WiFi.

Getting the same problem with 5ghz as well, have to shut it off and then reconnect to the router. Their networking coding is a disgrace, tons of complaints about it all over the place and Samsung does nothing.... I can't return my device but if you're still within the period of being able to, I would if I were you. I absolutely hate this device and all its problems.

I"m having a similar issue. First I noticed that LTE would stop working until I rebooted. Then the wifi would glitch up the same way. I'm not sure if it's the switch from one to the other, or what the deal is. The worst part is it's not repeatable. It just seems to do it randomly.

I have encountered the same problem with wifi dropping. I went to wifi setting and forget network and reboot. Punch the password back. Its working fine now. By the way im using the latest s10+ firmware rooted

Hi guys,
I was faced to the same issue since I bought my S10e. DO not mind the solutions proposed on generic sites (thecellguide.com, thedroidguy.com), they're garbage, totally irrelevant (reboot your phone, erase your cache blabla).
I've tried several hypothesis to troubleshoot this issue (very inconsistent wifi connection with my TPLink 4G routeur MR600, disconnecting every minute or so). In fact, tens...
And the final word seems to be, as observed by other users: 5GHz. After disabeling the option on my routeur (switching all traffic to 2,4GHz) everything is fine. For now.
Good luck

I've also had this issue on the S10E where the wifi would be connected but no internet. After a few minutes it would no longer see the wifi. 5ghz of course. 2.4 no problem. I noticed this happened right after login to Samsung account. Now that I'm logged out Samsung account wifi is all good. I'm on the oneui 2 Jan sec update.

I have the same problem with my girlfriend's Samsung S10, it keeps disconnecting from 5GHz. Just now I switched her to 2.4GHz to see if it solves the problem. All our other devices (HTC One M9, 2x laptops, raspbbery pi 3, chromecast, google home) have no problem with the WiFi on either band.
Samsung really has a problem with it's network code, I also had a problem at work with Cisco APs when an Apple device and the Samsung S10 where on the same network it would bring the whole network down. It was some multicast bug where the Apple would announce itself as the gateway only when an S10 was present.

It's happened to me but never until after the last update. I noticed yesterday I was connected with no internet.
