I ROOTED and unlocked my phone as soon as the option was available. Afterwards I entered the *#6335623# to change the wifi popup. Ever since I've had to manually connect the wifi to the closest signal. I've tried to use the same *#6335623# code on the dialer but it doesn't come up any longer. Has anyone had this issue because I haven't seen it posted anywhere.
I'm running Aokp on the latest vrlhe radio.
Does anyone have any ideas. It seems that it now not only doesn't auto connect to closest wifi, its starting to say that all the connects are poor signals even when 10 ft away from the wifi box.
Uncheck the poor signal option under advanced settings, and see if that fixes it.
Hi,
I am having problems with wifi drops under custom roms (I've tried several CM10 builds and AOKP's JB Milestone 1).
Under a rooted stock rom (UCLH9) and ATT installed kernel (3.0.8-985684) I get a very stable wifi connection.
However, if I install a different rom via ClockworkMod, I'll get wifi connections for ~ 30 seconds (or until data stops transmitting), and then it will drop out. I have to cycle the wifi on and off to re-establish a connection. Again, I'll stay connected for 30 seconds or less and wifi will drop again. The rest of the phone works fine.
Despite the dropped connection, the wifi icon (under settings) will say connected but show no signal bars. In addition, the phone nearly comes to a halt and hangs, as if all processes are being devoted to reconnecting.
This happens on at least two routers (one at home, one at work), so I don't think it is a router issue.
I've seen some people talk about the *#0011# dial code to turn off wifi sleep mode. If I dial this under the rooted stock rom, I'll get the menu as expected. But if I dial this code under either custom ROM first I see "USSD code running" and then I get an error "Connection problem or invalid MMI code."
If, after all this, I restore to the rooted stock ROM, wifi works and everything is fine.
Any suggestions for getting a wifi functional custom ROM installed would be appreciated.
Thanks

Sometimes getting a kernel for those type of problems fix it because they are basically replacing your phones access to your drivers (Wifi and so on)
This one puzzled me for a while. The rom comes preset to disable wifi after a certain amount of idle time. Go into Settings>Wireless & Networks>WiFi then press your settings button>Advanced> Keep Wifi On During Sleep> Set to Always. Maybe this is the fix to your problem.
This is happening to me right now with my LG G2, WIFI is stable on the stock rom but drops constantly with any custom rom. Did anyone find a fix for this?
I have tried several fixes including WIFI on during sleep to always, WIFI optimization off, different freq bands, I can't figure this one out...
I've been running into the same problem across numerous ROMs and kernels, all on clean installs. All of my WiFi networks are disabled when I turn my WiFi on, and I can only connect to them by clicking the network and then connect. Anyone know how I can fix this?
Anyone else have problems connecting to 5ghz any Wi-Fi networks after the Lollipop upgrade? I used the RUU zip to install Lollipop from scratch and I'm still having problems. First noticed the issue when I was setting up the account. Even then, the wifi would cut in and out when attempting to connect to my Wi-Fi. Not a router issue since other devices can access the network without a problem. Even then, after a router reboot it's still acting up. Rebooting the M8 doesn't help either.
Update: I was actually having problems with Wi-Fi in general as it turns out. Connecting to a normal 2.4ghz network was spotty and kept dropping. With 5ghz networks, it just didn't connect at all. I reverted back to the kitkat radio and everything is better now. Might try the Lollipop radio again too see if it may have been a one time issue or not.
In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!
Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?
Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.

It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).
UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
