After some time using wifi it just stops receiving any data but it's still conected
Make a full wipe, reboot and set the WiFi connection again
Sure, it's not your wifi modem ?
I'll try it cause it used to work fine on j005

I'm using j006a and wifi sleeps pretty fast, but it's not saying it's online. It reconnects fine though.
I know that there are problems with Exchange and such, but everything was working fine on my phone up until about 2 weeks ago. I have been running CM7 for quite some time and always left wifi on to connect at work and home. Never had any issues connecting to my Exchange account. Then I started to notice some connection issues with e-mails not coming in, etc. It was very random it seemed, sometimes on wifi, sometimes on 3G. So this weekend I decided to try installing CM7.2 and CM9 and maybe it would resolve my issues. Now I can get my phone to connect over 3G, but if I turn on wifi it will not connect, even after I turn wifi back off, until I reboot the phone. Not sure how to fix this problem, I enjoy using wifi quite a bit and it obviously keeps my data usage lower. Any ideas on how I can fix this? Currently running the latest CM9 beta.
Did you flash any kernel? Anyways try updating now the kernels are fixed today.

I made the thread here because it's not only a KQB rom problem, it's also happening on KQ7.
Now, i don't think it's a problem with our routers since on other roms it's working properly. It can't be a problem from our routers because the only setting responsible for this it's the DHCP Lease Time, but since the Wi-Fi is dropping randomly and not after a fixed time, it's not a "feature". For me it dropped after 5 minutes of connection. Then after 1 hour, then again 10 minutes, or 10 hours. So it's random.
Also the problem it's not the modem or wifi binaries, since i tried with KQ1 modem and binaries and the problem was the same.
So the last thing, i think it's a problem with the ROM itself, something that Samsung modified in KQ7 it's also present in KQB and it causes this problem.
We need a developer (skywalker, please? ) to look on this and maybe he can identify where it comes from.
Also we could try contacting Samsung, but I personally think that would be pointless.
A question for CM7 developer, skywalker. Can you make a patch or something for us to have the wlan or whatever from Cyanogenmod ? modem, binaries, and everything that relates and have a connection with the wifi/wlan. Since that's from Google and not Samsung, i think it will fix it.
P.S: Kernel is not the problem, i had this problem on KQ7 with stock and feacore nonOC kernel, and on KQB with stock and SkyHigh 1.4c kernel.
For me no dropouts since KQB
Hmm, my phone is simlocked, and when i install every rom i don't take out the sim card.
Could these 2 be the problem ? the fact that the phone is simlocked ?
since not every user experiences this problem (for me this problem also does not exist), it is impossible to say that this problem is rom related
there has to be other values which interferes the wlan connection
so you have to collect more informations about the phones which suffer from this bug
Can't do it alone if nobody helps me...
One if the reasons I'm still running KQ1.
Also tried the WiFi fix and KQ1 binaries, but still WiFi drops on KQ7 using the stock kernel and Feacore 1.4.
I'm running on a N-only, 2.4Ghz, 40 MHz, AES, WPA2-PSK, 300Mbps link on a TP-link WR1043ND.
Haven't tried KQB yet because of the other issues that rom has.
I have the same problem...since 2.3.5 stock rom
also i tried custom roms but without succes...maybe a experienced dev will help us
So any developer could look into this, please ?
I had wifi drops with KQ7 (broodrom) but they were solved using every fix broodplank provided to us: the browser fix, KQ1 modem and wifi binaries.

I'm on KQ7 and never had any wifi issues with any router I connect to (speedport w721v, linksys wrt54gl, devolo AV wireless n). For all those wifi networks, encryption is WPA2 personal and adresses are distributed by DHCP.
I can say the following: I have no dropouts on my home router (Asus N56U) which is working in 802.11n only (WPA2, DHCP) but I have dropouts at work (some old router with 802.11b/g, DHCP). I think it could be connected with this (but I am not sure as it could be just an issue of an exact router).
I have read a version that the phone just drops wireless connection for energy saving purpose (and that can be true as 802.11n should be more energy efficient)
I have also read that guys from 4pda.ru copied system files from KQ1 (some system libraries for wireless lan) and dropouts have disappeared.

Lol I was actually the one who released the KQ1 Wifi Binaries ^^, not that it matters but still, look in my rom topic
I installed KQ1 modem with Odin, then booted into recovery, mounted system and flashed KQ1 binaries from broodplank.
I still have dropouts.
I don't think it's the router, since when it randomly drops, the wifi button in status bar remains ENABLED but the connection is no more.

Can you track if the connection fails every ... seconds? Because if it's the same amount of seconds each time it's because of "wifi.supplicant_scan_interval"
Nope, i said it a couple of times already that it's pretty random. Can be 15 minutes, 30 minutes, 1 hour or even 5 minutes.
wifi.supplicant_scan_interval it's set to 180. What does it mean anyway ? and what's the value ? seconds ?

Ok then it's someone else, but what?. the command means that the wifi will scan every 180 sec for new connections, sometimes it happens (which is a bug) that after you're connected to a wlan, you will disconnect after the exact amount of seconds matching the value.
I have no idea what could be the problem. Anyway it's not a fixed time, it's random.
That's why i asked the help of a developer. Maybe he can notice something wrong in the rom regarding wifi.
So, i had same problem with wifi but i solved it. Model of my router:TP-LINK WR543G. In KQ1 everything was okay, but in KQ7 and KQB wifi stay connected only for about 1-2 mins, then dropped and i had to reconnect it manually in settings. KQ1 binaries and patches not helped. So i change DHCP lease time to max ( in my router, 2880 ), then switched wifi brodcasting channel to 13 ( anyone in my neighborhood are not in this channel ), changed security option to WPA2-PSK and encryption to AES and turned off "group key update peroid". That helped! Before that i was no able to use wifi cuz it dropps, but after i am still connected for about week, and everything works correctly
So it's a "feature" from Samsung in KQ1 and KQB.
The problem is that i couldn't find the right settings in my router, so the problem remains. Now that we know that it's a change in the ROM, we need someone to identify the change and change it back on how it was on KQ1 for instance.
Do you guys have wifi dropout during screen on or screen off? Because I have only dropout during screen off, leaving it in some minutes (i don't know how long) and then wifi is disconnected. I have already set wifi policy to never.
I'll try to disable wpa2 regroup key renewal...
I'm currently on MotoIcegun 1.0 which is an CM9 based rom and the wifi works very well just like the stock rom,a few months ago i try the new cm10 rom but it's always have connection problems after 10-15 min while i download something Does anyone know what influence this on my phone?Anyone else who have this annoying issue on some roms?
wifi disconnects when the device goto sleep?
if yes then wifi settings>advanced settings>keep wifi on during sleep>always...
otherwise.... try static i.p.....
Hello people of XDA!
I had my note 3 runnning on CM11, suddenly it wouldnt connect to my router 5ghz network anymore but it did fine on the 2.4GHZ i tought it was a CM11 bug so i restored back to TW now i can connect to the network but my Download speed is really slow (about 1-2 mbps compared to my laptop wich speedtests at 50 Mbps running the same wifi)
The question is: is my note broken (again) or what should i do ?
Great now i cant even connect to the 5GHZ network, if somone kind would help me i would be thankfull!
(You havent changed any settings in your router lately ? )
You tried rebooting ?
If wifi isnt working at all one of your last chances might be a backup + wipe system/clean flash of current ROM.
Use wifi anyalyzer on the play store, and see what channels other routers are using, if they are on the same as yours and there is an empty spot somewhere, try changing your routers channel to a free one.
I have had many issues in the past due to this, damn neighbours! Haha
This may not even help, worth a try.

Well im the only 5ghz network here nearby according to Wifi analyzer, strangely i can connect to the 5GHZ via wifi analyzer but after i exit the app it disconnects... Weird...
Could be the location settings under Google settings, caused me problems with glitchy internet in the past. Switched it to gps only one time and after that to desired setting and it solved the issue for me.
Hope it helps.
