WiFi keeps getting disconnected

Hello all,
i have noticed since the stock ROM and the new one i have put Domination HD the WiFi keeps getting disconnected every 5 minutes or so.. it connects automatically but it interrupts my video streams or downloads..
has anyone faced it and is there any fix?

I've had the same problem with 2 units.
Running CM9 now and it still does it. Pressuring AT&T for an exchange again....

Menu > Settings > Wireless & networks > Wi-fi settings > Press MENU button > Advanced > Wi-fi sleep policy
Change it as you desire. You probably have it set to turn wi-fi off when the screen turns off (default setting).

Had this problem too with my phone when it was new. I changed a setting in my router to allow a longer IP lease time and that fixed it. Set it for 2 weeks.

I'll give it a shot, changing the sleep policy in settings had no effect, it drops every few minutes regardless.

This is the only phone where I had to change router settings to keep a constant connection on Wi-Fi at my house. Hope it works for you.

It worked! Thanks.

My wife's phone drops her WIFI connection about three times a day. I checked the option in WIFI settings (WIFI Sleep-Never), that didn't help and I tried messing with my router. Unfortunately I didn't see anything in the router setting about the lease and making it last longer. Where should this be? I have a NETGEAR that my cable company gave me.
p.s. Hey kkernaghan7, what's going on in your profile picture?

Sorry to hear that things aren't working. I'm not up to date with netgear routers but just search for IP lease time, it could be in the dhcp settings for the router. As far as my profile picture goes that was a picture that my ex girlfriend took, I think its funny.

WIFI connection issue

I am unable to connect to my WIFI at home, I have tried everything I can think of, which is quite a bit. All I get is obtaining IP loop and then says poor signal and quits trying, (I have tried sitting right next to the router) My router shows that DHCP has handed the phone an IP, but the phone does not seem to take.
Tried adding a network manually
Tried advanced settings, and giving a static IP address, I can get it to show its connected but can not get any internet, data etc.
Tried the *#0011#
Tried a master reset, and tried to connect to wifi before installing anything.
I am at a loss, would not be a big deal but the 4G at home is sketchy, cuts in and out a bunch, plus for what I paid for the phone the wifi should at least work.
Tmobile tech support is not much help, neither is Samsungs.
Any help is appreciated!

Does your phone's wifi work on other networks? (Coffee shop, neighbor's, etc..)
What type of authentication is your router using? Try disabling authentication and see if it works.
What model is your router? Does it have up to date firmware?

Yes it connects to my work wifi.
WPA/WPA2
Its a Belkin router, not sure of the model off the top of my head, I know its somewhat newer cause it has the N protocol.
I would really suspect the router if I did not have other devices that work fine on the network, 2 kindle fires, 3 laptops, 1 S,Captive, Wii, and Xbox, and my Vibrant worked fine till I got this phone. Not everything is on at the same time, but I am sure that would not matter cause I have never had an issue when it all was connected at the same time.

Have you flashed a kernel lately? I have issues connecting to my router flashing some kernels. Just a thought.

Or if you are on a custom rom, reflash the same rom again.

same issue
I have the same issue, but my Wifi wont connect to any network and actually show throughput if I set the wifi power **** to off with the *#0011# menu.
I was stuck on stock roms because akop based (cmx) dont have that service menu.
I recently flashed to Uvalh2 stock rooted and the wifi works as it should for the 1st time ever. I flashed back to ulvem and it needs the 0011 **** again...
my home router is also a belkin with b/g/n, but my wifi never worked anywhere without the menu trick;
ANY help to troubleshoot if this is radio/kernel/rom based or what setting the menu changes so we can possibly set it manually in terminal..
thanks for this thread

Best I can think of real quick is to try different kernels and modems. (Check out the Modem Flasher in dev, makes it really easy)
Sent from my SGH-T999 using xda app-developers app

Just hate the fact I have to try other kernels and modems after paying an arm and a leg for this phone, should not have to.
And seeing I have never done that before it makes me heisatate even more, I am sure I can do it, just that whole what it.
I just dont get why if I give the phone a static IP then it will connect, but can not move data, I went to the *#0011# and was able to ping the router and laptop on the network etc. I am at a loss

Anyone have any other suggestions on this issue???

[Q] SOLVED. Why can't I connect my Galaxy Note 2 to a secured Wi-Fi network?

I got my T-Mobile (US) Note 2 Wednesday and can not connect to my secured home Wi-Fi OR any other SECURED network.(I have a Motorola Surfboard. It is less than a year old) I spent 3 hours googling for a solution and I've rebooted and reset my router many times. I have logged in and reconfigured my security setup multiple ways without any luck.. my searches have said sometimes there is an issue with Samsung phones connecting to secured Wi-Fi..
I have tried to connect on two other secured Wi-Fi networks (different model routers) with no success. I have all the passwords..
I have tried the WPS button and WPS PIN option multiple times. Aarrg!
I CAN CONNECT TO OPEN NETWORKS (including public)THOUGH!..
I paid $690 for this phone. I have very poor reception when home and NEED Wi-Fi for calling purposes. I love this phone and don't want to return it ($50 restocking fee, lol).. I am completely stock NOT rooted
Any ideas?
**SOLVED**
I was holding my WPS button connection for 2 seconds instead of the 10 seconds needed for my Router.

BTW. I have done multiple factory resets on the phone.. I really have been working at my issue. Hopefully someone can help me.
Thank you all for reading.

Why don't you go Tmo store and try connect to their network , if not connect to Tmo store network .Tmo must replace the phone for you free .

I'm away for the weekend so I am going to have to wait until Monday. I just wanted to make sure it wasn't just my router first.. I was also hoping I could find a fix here.
Thanks for replying.

Finally i got solution
Just change mode DHCP to static and follow other process like add ip and all and save then turn off wifi and again turn on it work fine

5GHz WiFi not working, well sorta....

Wondering if anyone else is having issues connecting to a 5ghz network? I wasn't able to get it working, wouldn't even show up in available networks. That was stock out of the box, and after flashing a couple ROMs. I'm using slimbean now and am able to connect, but I have to turn WiFi on/off several times on the n7 before it shows up and connects. My s 3 connects no problem.
And I've tried all the standard troubleshooting on the router. Even changed some settings on the 5GHz band.
So if someone could double check for me that would be great!

5ghz works great for me. Reception is the best I've ever gotten on that band. Currently on stock, but it's worked in CM10 too

The 5 ghz didn't show up for me either. Had to manually enter the SSID and it connected right away.
Sent from my Nexus 7 using xda premium

On the first boot it didn't show my 5GHz WiFi, but after I connected it to my 2.4GHz, it immediately downloaded an update and rebooted itself. When it came back up, it saw my 5GHz.

Mine didn't at first either, but after update/reboot no problem. Now connecting at 150meg on 5ghz.

Still hit or miss for me. Sometimes its connected when I reboot. Usually I have to toggle WiFi on/off 2-3 times.

My Nexus 7 connects to my 5ghz router band all the time. I think it actually prefers it. I'm using it right now.
Sent from my Nexus 7 using xda premium

Well I think I have it working. I gave the n7 a static address and now after a half dozen reboots its auto connecting every time. I tried changing channels on the router. Tried 20/40 MHz channel width. Ticked on/off all the options on n7 WiFi settings. Nothing worked. Then I set static address on my tablet and router and like I said so far so good.
I'll update if there are any other issues because doing a search showed a lot of other devices having this issue. But none of the results recommended setting a static address. Maybe I got lucky. I could use my 2.4GHz network reliably but I want full network speed since I only have the 16 GB model and do a lot of folder syncs to keep my SD storage free.
Edit: scratch that. Worked half dozen times in a row. Rebooted after I wrote this and it didn't connect.

During initial setup i was not able to connect to my 5ghz but i was able to connect to my 2.4ghz. After setup was complete i was able to go in and switch it manually to the 5ghz network. If i power the device off and turn it back on it would not connect to my 5ghz or my 2.4ghz. I then went into wifi advanced settings and switched to 5ghz only and it connected immediately to the network and hasn't lost it since. This was true before and after the update, i am stock, unlocked and rooted. I also do not broadcast my ssid.

If I am connected to 5ghz and go in advanced and select 5ghz only, it disconnects me from WiFi. It will still show my 5ghz network in range with good signal but if I now try to connect..it does nothing. Keep clicking connect and nothing happens. Then go back and put frequency on auto and the 5ghz disappears. I then have to toggle WiFi 4-6 times before it connects again to the 5ghz.
Strange.

I had the same problem at first too. Here's what solved it for me: set 5ghz frequency to 20mhz instead of auto, change the channel from auto to any number you want, 5ghz will most likely be completely clear in your area so just choose any channel. After doing that it should see the 5ghz network every time and connect automatically.

Same issue here. But i have to restart my device. Is it hardware or software you guys think?

I'm not sure. Seems like software to me because once its connected it stays connected. And the signal range is really good. Better WiFi than any phone I've ever had. Better than my laptop too. My s3 has no problems connecting. Even with all the router settings I've tweaked its never had an issue connecting with the s3.
Are you able to connect?

In another thread someone noticed his WiFi settings were set to Europe. He said he hadn't changed them and that he was fresh on stock (his first time booted). Double check your settings if you're still having issues.
Settings | WiFi | advanced | WiFi region code.
Mine was also set to Europe as well for some reason. If your router is setup to use a channel not available in Europe this would cause the problems described here.

Update..powered on after a few hours and it did not connect to 5ghz. Went in to the advanced settings and switched from 5ghz to 2.4 and back again and connected right away. Will try the region code, to see if it helps.
update to the update: flashed vanir 4.3.081213 and wifi connected to my 5ghz right away and has continued working through two reboots so far. On stock rooted 4.3 i had to toggle wifi frequency to get it to connect after every reboot.

OK guys, I think I have as real solid lead on this bug. I'll update with some info a little later, I want to test this some more. But for now I'll say that I made some changes and I have had zero disconnects or problems connecting while toggling or after reboot. And I mean 100% connection rate after 50 toggles and a dozen reboots.
Till I can get the info up, one question for you guys having the same issue. Do you have multiple routers in your network and/or custom firmware on your router?

Odd wifi issue.

I'm running stock unrooted now since the 4.3update.
I noticed now that I cannot connect to wifi routers without an Internet connection..
I race rc cars and we have an app. That pulls results from a laptop via wifi... When I attempted to connect I get an error "network connection disabled because Internet is slow" all other Android users can connect including other gs3... I just tried at home to get the same error. If I pull the phone line same error. So it appears I cannot connect to networks that don't have Internet connections..
This is a problem I never had before going official ota Rom...
Is there a setting I should look for in settings that maybe off?
Thanks

I can stay on my wifi now with a Warning of no Internet
