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.
Hi all, happy Friday! I searched for my paticular issue but couldn't find anything. Just wondering if anyone else has experienced this issue or something similar. What happens is my revo isn't automatically reconnecting to wifi when i go out of range and then back in. I will notice it's using data (4G or 3G) and when i go to wifi settings the wifi network says disabled and i have to go to it and hit connect. What's more weird is it's doing this with the wifi at work but not at home. It's not an issue with the wifi at work though because other people here have androids, iphones and blackberrys and don't have the issue. The phone has done this since i got it. I've looked at the wifi sleep setting and made sure it is set to never to rule that out. I've done several powerdowns and battery pulls since i got it also. Anyhow just wondering if anyone has heard of this. Thank you and sorry for the length of my post.
That happens on my phone as well, but will reconnect to my home network after the screen is on for a few seconds

I don't have that issue but I always turn my wifi off when I'm not using it. Better battery life plus no issues
Yeeup, I've had that exact issue on this phone from day 1. Some may not consider it a big deal, but it's actually one of my biggest pet peeves about the phone. I was hoping the V6 software update back in August would contain a fix for it, but I didn't notice a change.

While that's a valid workaround, and i'd love to do that, it's not an option for me. I have the lowest data plan you can have on a smartphone (2gb), so i have to be on wifi whenever it's available so as not to go over usage. What's odd though is the phone only seems to do this with the wireless at work. I even went somewhere this past weekend that i haven't been in a while and the phone remembered and connected right up to the wifi there. Other smartphones at work don't behave this way with the wireless at work though. I'll just have to live with it, i'm used to it now anyway. Just have to remember everytime or i'll be using up my precious data. I'm wondering if the update to gingerbread (if our revo ever get it) will do anything with this issue.
What type of security is implemented at your work? I know there is a very common problem with PEAP and MSCHAPV2 authentication and FROYO. I can connect, but as soon as I change to another antenna, I get disconnected. It is the only reason I know I want Gingerbread. It was supposed to be fixed in Gingerbread.

Good question gig, work has 2 networks. One uses PEAP and the other is for guest internet access, i have it on the guest. I gather from what you've said it wouldn't help any to try this issue on the main PEAP network.
I have an update on my issue. I was at lunch yesterday and trying to connect to the free wifi there and noticed that the wifi network at work that's been giving me problems was on the list of remembered networks twice! I have no clue how this happened (in troubleshooting i always hit forget). I didn't even know it was possible for any device to have duplicate entries of wifi networks. I deleted one of them and it seems to have worked (so far). Some other people replied saying they were having my issue too, so i wanted to update this thread in case it would fix their issue too.
Is anyone else having an issue where your device will be hooked up to a wifi network, will still indicate you're connected but no data will sync? I email myself and nothing happens. Happens with FB, Email, Gmail, and Voice Controls don't work.

I have that issue with my gNex and my wife's DNA on our home network. I don't think it is necessarily this phone, but I am not convinced (yet) that it is my router, either...

I called Moto and after dealing with their terrible level 1 support I got the following:
HERE ARE THE INSTRUCTIONS FOR DOING THE WIPE CACHE PARTITION:
This will remove any temporary files that may be causing the problem, but will not delete your files or settings.
1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence
Ever since it hasn't had any problems, but it's only been a few hours as well.
The issues started happening again...turned off wifi and everything resynced perfectly...

If it doesn't work properly with a different router try exchanging it. Also have you gone into advanced WiFi settings and forced the moto x to 2.4 GHz? If give that a try.

The force to 2.4ghz actually made the problem occur a lot faster, any reason it might be due to the massive amount of wifi networks around? When I set to scan 5 ghz there was only one still open, I might go into my router and see if I can change the atenna settings.
EDIT: Turns out if I go to 5 ghz my computer can't connect, but I changed the channel to something less populated in the area to see if that helps.
DOUBLE EDIT: It appears to occur after I'm supposed to get a Facebook notification, at that point I don't get any more notifications....attempting to clear out facebook data and cache to see if that does anything

You mean full reset? It looks like I may have to do that with the idle battery drain issue anyways....so that's the last resort.
Hey guys I'm having a similar issue with my moto x on the 2.4ghz band. Speeds are very slow and sometimes cut out completely. Im getting a download speed of about 300kb/s on 2.4 both on auto channel and it doesn't rlly change once I change it manually to an open channel using WiFi analyzer app. My download speeds on 5ghz hit 4000kb/s even with a much lower signal strength.
YouTube and Netflix is unusable and growing the internet sucks. I usually just use the 4g network while at home cuz its a thousand times faster but I'd like this to be fixed regardless. Has anyone found a solution or explanation?

I'm having these issues too. Got the GSM Developer Edition on 11/29. It immediately updated to Kit Kat OTA so I'm not sure whether it had the issue prior to Kit Kat or not. This only happens on 2.4 ghz wifi and only with one of my routers at home, a Netgear WNDR3700v2 running OpenWrt Attitude Adjustment (I tried upgrading from Backfire to see if it would help, it did not). The other router is a Linksys WRT350N and when the phone is connected to that one the problem does not happen. Note, that there are 2 laptops, a Samsung Galaxy S2, and a Kindle Fire HDX that have zero problems with the WNDR3700. All can transfer data perfectly fine and at high speeds. Thus I do not think the router is bad. Have not checked work routers. 5 ghz wifi is totally fine and indeed very good with this phone.
For me, the problem is that the phone seems unable to receive data at high speed (over 1Mbps) on 2.4 ghz wifi in any area where the signal isn't perfect and sometimes even in the same room as the router (although usually it is fine there). Oddly in many cases when it has trouble receiving it can send data much faster. It almost seems like it might be some kind of interference as it is rather random.
At this point I'm wondering if the phone has a defective 2.4ghz subsystem, though that seem unlikely due to good transfer with the WRT350N, or if this is some kind of wifi tuning software bug in the phone.
Any info would be appreciated. Does anyone have this issue who did not have the issue on Jellybean? Am wondering if anything changed with wifi for the update? Note, I have tried clearing the cache in recovery as noted in another thread with no luck. Anyone have the WCNSS_qcom_cfg.ini file from Jellybean for this phone? Would rather not reflash just for 1 file.
Thanks.

For what it's worth I have this same Netgear router and have had the same connectivity issues on both 4.2.2 and 4.4.
I did some reading today and found a couple possible fixes I plan on trying out. First one is to disable WMM. Secondly I found on the official netgear forums that they have had major issues (some of which you've described) with all firmwares ending in the .30s and went so far as to pull them from their download section.
My router was running firmware .36 and I successfully downgraded it to the latest stable firmware .12 that netgear now recommends.
Hopefully 1 of those 2 fixes improves the performance, at any rate I really think it's something with the router itself and not the moto x.
Sent from my XT1060 using xda app-developers app
Thanks for letting me know this was also an issue on 4.2.2. Saves me the trouble of flashing back just to test.
I will be interested to know if your using official netgear 1.0.0.12 firmware fixes the issue for you. I haven't actually ever used the official firmware as I've run OpenWRT since I got the router a year or two ago. 10.03.1 had the issue, and it appears 12.09 does as well. I may try a trunk build at some point to see if that changes anything.
I had previously written that all was well on the 5 ghz band. This appears to not be 100% correct. Yesterday evening and this morning I found myself "connected" to the 5ghz band without actually having working internet. Toggle wifi on/off fixes it, but I shouldn't have to do it.
Not sure if this helps, but on the 2.4 ghz side things do work better on one side of the house vs the other. Also it seems that I can get a very fast connection at times and then it stumbles and gets stuck going under 1 Mbps. I still suspect either a defect or some kind of low level radio issues with the moto or the router regarding interference from neighboring wifi access points (there are a lot around me, single family houses on small lots). However, keep in mind no other device has these issues but the moto. In the rare instance I venture into a bad signal pocket the signal indicator goes down and speed slows or they lose connection vs the moto where it can show excellent signal and have no/nearly no connectivity.
I haven't tried it for long, but switching to wireless g mode vs ng may improve stability though I only briefly tried it. I did walk around part of my house checking the Mbps with the app "WiFi Speed Test" and while way slower than N mode it was far more stable. Even if this does work it is a definate downgrade in speed though.
Well its only been a day or two so it may be too early to tell, but so far my wifi seems much better after making those two fixes I mentioned above. This is on 2.4 band, the 5ghz band doesn't provide me enough signal strength to use all the time (router is too far from my bedroom).
The main issue I was having was my wifi signal would cut out even though it still showed a good connection. I could swipe down on the status bar and see no download arrow next to the wifi icon so I knew I wasn't receiving data. However a simple disconnect and reconnect to my wifi would fix the problem until it happened again. This seemed to be most common while watching YouTube videos, in fact it happened far too often which is why I went searching for a solution.
So as I mentioned things seem to be better for sure so far but I need to give it a week or so to see how much it is really helped, but so far I can't remember any wifi cutting out since I've made those two fixes.

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!
Not exactly certain where to post this (as I am not altogether certain the cause) so if mods have a suggestion to move it let me know.
I have a rooted Tmobile S6 (not rhe edge) running Sick as Hell custom Rom version X w/ Unikernel v9.
Periodically my WiFi signal will display the ER041 - DNS (or less frequently the ER081) error which I believe is related specifically to WiFi calling.
My GF has the exact same phone and the same setup (I think she has WiFi calling enabled as well).
I have run some tests previously where I turned WiFi calling off and still had hiccups with the WiFi (both home and at work).
It seems that when I clear the cache and reboot the issue resolves itself but only short term before I have to do it again.
No one else in the house is having WiFi issues such as me and I cannot seem to figure out if there is a setting that is throwing things off or what.
Any help is greatly appreciated.
Mine does this too but it usually clears itself up within a minute or two.
OP, check your IP address to see if your phone is getting an IPv4 address. I don't know why, but my phone was having major issues with this. I still haven't figured out exactly what the issue was; I was on Sow Nice, flashing back to stock solved the problem. The phone was getting an ipv6 lease, just not ipv4, for no apparent reason.
If that doesn't help, I would advise setting network configuration manually. However if ipv4 isn't working, this may not solve the issue.
WiFi Issues
Alright gang I need some brainstorming...and curious if any other T-mobile Galaxy S6 users are experiencing this issue. I don't believe it is ROM related but thought I'd post the inquiry in here anyhow.
Specs:
T-Mobile Galaxy S6 (SM-G920T) rooted with Sick as Hell X and Unikernel v9.1.
Baseband: G920TUVS3DOJC
Issue:
WiFi is intermittent (both work and at home). WiFi will be running fine on this device and also on my Kindle Fire and at some point WiFi on my S6 will stop working. The WiFi icon will still appear and the up/down arrows will flash but I can't pull up Google search results, YouTube videos, etc.
I get a ER041 - DNS error which is related to wifi calling but I think this issue is in fact DNS related (I've googled and googled and am just not entirely certain, if it is DNS related, exactly how to change settings to thwart this issue going forward).
If I run a speedtest I will get a "Network Communication Issues" message. If I turn off WiFi and then turn it back on the connection is still broken.
HOWEVER, if I clear the cache and reboot the phone, it will connect to WiFi for a period of time until the connection gets broken once again.
My phone seems to be the only device experiencing this issue. I have booted into Safe Mode and the issue still occurs so it doesn't appear to be app related. The Smart Network switch has always been off as well so I know that isn't the culprit.
At work I'm not going to be able to check the router settings but obviously I can at home (at home 4 other users connect to WiFi no problem).
There has got to be some sort of tweak/button/setting that I'm just not catching that is causing this. It is irksome.
I recently did a factory reset but the issue is still persistent. Scanning the interwebs this seems to be a pretty common issue with the S6 and Lollipop.
Any ideas??

If that doesn't help, I would advise setting network configuration manually. However if ipv4 isn't working, this may not solve the issue.

Ya lost me on the IPv4 ipv6 lease jargon.

Hmmm...well then, Twisted v7.1 has yet to settle in so I guess I can let it ride for a couple days and see how things go.

Keep in mind, the other kernels are international
source.
EDIT.... also uni kernel adds a default.prop in system that has ro.securestorage=false when it needs to be set to true for USA devices
I'd say at this time I can rule out the kernel (it's a been a few days now running Twisted v7.1). I honestly think it is a Samsung bug. Not just S6 users but Galaxy S7 users are now reporting the issue as well (there is a thread over at AndroidCentral).
Just like myself, those users are reporting that Smart Network switch and Blutetooth and the like are turned off/disabled and yet the problem persists.
I've had WiFi issues on an s6 edge. But I figured it out that if I'm near my microwave and it's on WiFi dies on the phone. Soon as the microwave goes off it works fine ?

Huh. Not the case in my situation. I've got a microwave but it's in the basement and rarely used.
