How to resolve it? I tried already different gapps and different kernel. On stock 4.4.4 everything is working fine.

[Q] Wifi suddenly not working on Cyanogenmod 7

Hi all! I've recently installed cyanogenmod (probably 4 weeks now), and I am loving it.
Everything seems to be working fine, then a few days ago my Wifi couldn't detect networks anymore.
I tried rebooting and to no avail.
Any advice would be most appreciated!
Thanks!
If it is only having problems with one Wifi network, chances are it's the network. (reset password/restart router/change channel the routeris on/or encryption)
If it happens with several wifi networks. Back everything up and reflash with that ROM again.
EDIT: Read this too

You can try install everything again or try install a file wifi fix...
do you have a link for the wifi fix?

[Q] Wifi on CM10 not working on phone, but working on laptop

So I originally had the 11/29 nightly of CM10 on my phone, then decided to update to the 12/02 nightly and WiFi was working normal as usual, then I disconnected for a few minutes and reconnected and it won't connect to the IP Address for some reason, I've tried reflashing the ROM and even going back to the 11/29 build and it still won't do it. Is it my router or my phone? I've tested the kernel and that wasn't the issue and obviously neither is the ROM

[Q] xt910 bluetooth re-pairing issue

I have a xt910 and using cm11 4.4.2 dated 30/01 build umts spyder. I have tried several builds of kitkat and they all seem to have the same issue of needing to re-pair bluetooth connections when coming out of flight mode or rebooting. My stock slot rom is 10.1 and that works fine, but when I boot into kitkat on slot one there is this issue with the re-pair. Is this an issue with being in a rom slot and may not happen as the stock rom, I dont want to stuff around with changing incase the problem still exists. Is there a work around that someone can point me towards? thanks

Weird wifi connectivity problem

Hi guys, i have a Sony Z2 D6502. I am facing a really weird wifi problem. I can use and connect wifi on 4.4.2 or 314 official, and also cm 12.1 build 5/22 and the previous ones. but when i flash official 5.0.2 build .726 or .28 or newer cm12.1 roms such as build 05/25 or 06/02, my wifi acts crazy. First of all, if it would connect to my router, it can only stay connected for 10-15 seconds max. But most of the times the wifi sections is searching for signals and wifi ssid's constantly show up and then suddenly disappear, and this process of searching continues endlessly. But as i said, sometimes it would connect for 10-15 secs. Also some other times, i will just get a "failed to connect to network" error and it seems the device wouldn't even attempt to connect to the network. i have tried flashing using full wipe, and even flashing existence y patch for d6502 baseband and it didn't help my situation. Come to think of it, I have to say that i have never really been able to use stock 5.0.2 with a normal wifi. When i first tried d6503 lp update with d6502 patch i had the exact issue, and that is the reason why i switched to CM and CM12/12.1 were working normally until the newer releases (05/25 or later ones). If any of you know any solution or any ideas or fixes, i'd really appreciate it.

if you with stock .726 or .28 have issues, then; or you have a faulty d6502, or you have issues with the AP's you are trying to connect maybe.
i would flash .28 and go to a Sony Repair center, im sure its still on warranty.
its hard to me to mentally visualize your issue and fix it, and even so, seems you are the only one reporting that issue ...
