I have an MSMT-320 running Cyanogenmod 13.0 (13.0-20161219-NIGHTLY-mondrianwifi) and I've been having issues with connecting to wifi. It will cycle through disconnected > authenticating > obtaining ip address > connected, no internet > connected and then back to disconnected. It does so rather quickly, sometimes resetting at different points in the cycle. It's been doing this occasionally for several months, but recently it's been almost all the time.
At first, resetting my ATT modem/router would fix it. I was having other internet issues (speed, mostly) and had the modem/router replaced recently and that did not fix the problem. In fact, resetting it has no effect recently. I tried restarting the tablet and turning wifi on and off with no luck. When this started (with the old modem/router), I was able to connect fine at work or my parent's house. I haven't tried anywhere but home recently. However, no other devices on my home network were having this kind of issue with the old or new modem/router. When it did connect, it ran fine and I had no issues.
Today I decided to try a factory reset. As soon as it came up to connect to wifi, the same issues came back. In fact, I cannot even sign into my Google account. Either the wifi is lost, or it cannot reach the Google servers or it just says an error occurred. I've even gotten an authentication notice on my phone from Google, but it still throws an error and fails.
Any ideas on how to fix it?

Soooo,... I seem to be able to connect to the wifi everywhere but at home on my linksys 400N. Everything was ok, a couple of hiccups, then things progressively went downhill until last friday then everything went dead with the wifi. Everything says it connects with no issue, says it is connected and doesn't drop but I get no data from surfing. Went to my sister's place in NY, and had no issues with her connection, everything was fine. Things I've done:
- Froze my account.
- switched from wep to wpa to wpa2 to no protection
- currently upgrading to Jugs 4.0 for KL1 will update back *Did not work*
- switched out routers to my old wrt54g
- toggled data packets, airplane mode, turn wifi on/off, jiggled the handle,...
- power cycled everything in the house including the refrigerator,....
- tried setting up a static ip addy
- have no mac filtering
- every other wifi device in the house has no problems.
- update got new sim card and didn't expect anything, but didn't help either.
at best i get a blip of wifi then it goes dead. I'm starting to get stressed. Obviously the phone's wifi works, and i've heard the wrt400n is a little iffy, but is there anything that i have missed?
singled out the router
avoid the wrt400n router. it does not play nice with the t989. soon as i plugged back in the trusty old wrt54g and sorted everything out there were no more issues
Here's the deal: my S2 keeps disabling its WiFi connection. I’ll be connected to my router for a while, sometimes for 12+ hours at time, when all the sudden my S2 will lose its WiFi connection and switch to 4G. When I go into my WiFi settings, it will say that my router is “Not in range” and show no other available networks (even though there are dozens in this area).
I can sometimes get my connection back by toggling Airplane mode or “use packet data” on/off. But nothing works %100 percent of the time. I don’t think it’s a router issue either because we had 4 smartphones in this house over Christmas and the only two that lost their WiFi connection were my and my wife’s S2s.
Anyone else encounter this?
(p.s. Phone is stock, by the way.)
If you have the Tmobile my account disable or uninstall it.I made a thread about this awhile back. It has something where it needs to stay connected to 4g or intermittently puts data on and cuts wifi off I used to have this problem before not no more after uninstalling it.
Thanks, sarni. I read your thread a couple days ago (when I was trying to figure out what was going on), but I'm not sure we're having the same issue. My WiFi and 4G icons aren't on at the same time, for instance.
The other problem is that I haven't rooted my phone, so uninstalling T-Mobile's "My Account" app isn't an option.
Yet.
Happening again now.
Phone seems to be stuck in the following loop: scanning for available WiFi networks, seeing them all, locking in on my WiFi network, trying to obtain an IP address, then back to scanning again without a connection.
No toggling of settings broke the loop until I powered on/off.
I need your help everyone. My brother is using the Galaxy S II running ICS 4.0.1 that was bought along with my S III and it is acting up. GSII is running stock ICS, and still in stock configuration. Phone is not rooted or messed with in any manner. The phone connects and stays connected to the Home Network, but data transfer stops after few seconds. All the other devices at home (laptops, PC, other phones) stay connected and works fine. Home network is through Century link and wireless is through actiontec modem and wifi router - http://www.actiontec.com/products/product.php?pid=264#.UOyOPB3aI7s). He has been using this phone with no problems with the same wireless network for almost 4 months and this issue started almost a month ago. I have no idea why it went wrong all of a sudden and not had any luck in finding a solution from all my research.
Problem: When WiFi is activated, it will connect to the home wireless network and will work for few seconds. As soon as background activity that requires data stops, the WiFi stops working. If I am browsing or a video is playing on Youtube, it will stay connected, but as soon as I exit out of the application that is pulling data, it stops working. I have to turn it off and back on again for it to work, but this issue repeats. From looking at the signal bars for WiFi, its full (I was sitting next the router) upload arrow blinks once in a while but noting on the download. None of the apps are connected to the network. Browser will show loading for a while and then displays no network connection message. I tried google play, youtube, third parts apps etc. to ensure its not just the browser. When I turn off the WiFi, the phone seams to download a bunch of messages and updates that was not being pulled for a while. My GSIII connects fine with the network and it works fine even after being idle for hours. I have no idea what is going on and would really appreciate any help. I am close to calling Samsung and T-mobile, but thought I will try here first as we all know how easy it is to deal with those guys.
Things I have tried so far: I have tried all of the following based on suggestions I read from other forums I found through google search.
1. Factory Reset the system: FAIL. After the reset was complete, I waited for everything to finish loading and then I connected to WiFi by inputting all the necessary details. Same results, will work for few seconds and stops.
2. Restart the Modem and Router: FAIL. I do not think it is modem or router related issue as my S III seams to connect and work fine.
3. Turn off the security for wireless network: FAIL. Same result as above.
4. Try different encryption: FAIL. Same result as above.
5. Forget the Network and redo: FAIL. Same result as above.
6. Change the IP address to Static in advanced settings for the network: Worked for a while and then this stopped too.
7. Change WiFi sleep policy: FAIL. Changed it to " When device sleeps", "Never" and "Always", does not make any difference.
8. Third party apps suggested by everyone: FAIL.
This is where I am at right now. I have tried to include all the information possible. Please ask me if any other information is needed.
Last resort ... try a warranty replacement.
Is the phone experiencing the same issues with other wireless networks (coffee shops, McD's)?
[Fixed]
The issue was not with the phone, but with the router/modem. This was the century link modem with wifi and router from walmart that was bought for $99. Its an actiontech router with built in modem for century link. This does not work and dont bother purchasing it. I ended up buying the NETGEAR DGND3300 RangeMax Dual Band Wireless-N Router with Built-in DSL Modem from Amazon (http://www.amazon.com/gp/product/B001UHMB5O/ref=oh_details_o01_s00_i00) for a 30 dollars more, but it works. Only extra step was that i had to call century link for my username and password that needs to be entered during the setup procedure. The actiontech from walmart did this automatically (mainly because this was a century link branded product).
Out of the blue, my WiFi stopped working. I know occasionally this happens and is usually fixed by simply turning WiFi off then on again our by unplugging the router for about ten seconds, but neither of these methods is working this time. This is different, I'm stumped. (By the way I have the SM-P600)
So, the error message I'm getting is, "failed to obtain IP address", then if I click, "RETRY" I get an error message that says, "Network disabled because internet connection is too slow." Which doesn't make sense because all my other devices on my WiFi network have no problems connecting and have no speed issues.
Really, really frustrating. Any help would really be appreciated! Thanks!
The same problems occurs frequently with my tab P-601.
But I have to restart the tab and it works fine. I have to use mobile data for internet connection instead of wifi.
I appreciate any help.
Anybody else have this happen?
I haven't had this problem on my P600, but have had something like it happen on other devices. I think the issue is that Android will remember and avoid WiFi APs with a poor signal. When I am on the fringe of my home WiFi the signal is weak and my network gets blacklisted. To clear the blacklisting I have to force the device to forget the network, the connect again as a new network.
Couldn't detect WIFI
I updated the Android 4.4.2 and since then my tablet couldn't find my WIFI.
My phone and my computer found the network normally but my tablet just showed some of my neihbors' networks. I tried to restart the tablet and reset the router but didn't help.
Now I tried changing he router's settings through my computer and set the frequency to a higher value and now my tablet finds and connects to the WIFI normally!
I don’t use the MS-T800 that often so when I do there are a bunch app updates. Last night was no exception. This time as the updates installed at some point I kept getting a popup showing a connection to my D-Link DIR-655 access point. I then saw that it was affecting my phone as well and even the network. I’ve had the MS-T800 for over a year and never had this issue. With the MS-T800 off everything is fine but when it is on and wi-fi is enabled my D-Link DIR-655 access point keeps resetting every minute or so.
I’ve reset the network settings but it’s still doing it.
Bump.
