CM 13 Snapshot wifi disconnection - ONE Q&A, Help & Troubleshooting

I just flashed CM 13 snapshot and I am facing wifi disconnection problem. It works on my home wifi properly but on my library wifi it never connects even if enter correct password it says connecting for few secs and then shows saved thats it. Some times it connects out of no where but keeps on disconnecting and connecting again and again ??
Please help I am having nightmares because of this stupid problem.

Switch to a stable ROM. Snapshot is not stable and will likely have issues.

[Q][NS4G][D720][CM9] Wifi connection issues

I am running the latest version of the ROM found here:
http://forum.xda-developers.com/showthread.php?t=1519138
I am having basic issues connecting at home; once connected I am fine but sometimes if I leave and come back I can't connect at all. Rebooting had no effect. It will just sit there and do nothing even if I try forcing it to connect or forgetting the network and resubmitting the needed information.
It is worth noting that while running stock 4.0.4 before I flashed the rom I had little to no troubles with wifi; it even handled EAP like a champ (I have yet to test it on EAP with this rom).
Any/all help is appreciated...thanks!
**EDIT** I believe the problem may have something to do with the fact that I am running the latest CM9 nightly on my HP Touchpad, as only one device seems to be able to connect at a time, although I know that they both can and have connected simultaneously. The device that doesn't connect seems to have issues obtaining an IP Address from the router.

[Q] Wi-Fi / MAC address issues on my OPO

So far, my wi-fi has been working fine on Android L - except for when I'm home where my router has white-listed its devices with their MAC-addresses. It worked fine when running Android 4.4, but I had no success yet on Oxygen, cm12 nightlies or cm12s.
Whenever i try to connect, it says "Connecting.." and switches to "Saved" after some time and then tries to connect again. I have removed the whitelist and it connected fine - but as soon as the router restarts, I can't connect again. Even if my device's MAC address is whitelisted.
Strangely, it does connect once after a fresh cm12 or Oxygen installation, but only once. Disabling and re-enabling wifi will not let my OPO connect to it anymore.
Anyone having similar issues or any advice? It seems like my OPO doesn't want to reveal its MAC address to my router. Other devices can connect without any problems.
From Ubuntu Touch porting I know that the OPO uses a default (private) MAC address at startup until it get initialized with the correct one, save somewhere in a config or firmware partition. We are also currently unable to use more than 2 OPOs in the same network due to MAC address collission. Maybe you have the same problem, as it turns out, as our port is based on Lineage/CM for OPO.

Try flashing the modem/radio from one of the latest stock fastboot flashable ROMs perhaps? This may resolve your issue, especially if you where on a stock ROM that was old before you started flashing custom ROMs. There was once an app that would allow you to truly spoof your Mac address, but I believe it wasn't working for anything above Jellybean or Kit Kat. It used to be great help for moments such as these.

WiFi does not work properly when Bluetooth is turned ON

Some weeks I have a BT device when connected to my N5 (6.0.1 - MOB30H), and I noticed that the Wifi is with many problems (do not connect to wifi; when connected, do not down/up or is very slow) and immediately after I turn off BT, everything returns to normal.
Already tested with other BT devices and the problem persists. Even if without any connected device, the simple fact of turning on the BT is cause the malfunction of WiFi.
I've tried wipe and the problem persisted.
Does anyone have the same problem? Any solution?

Spontaneous wifi shutdowns

Hi,
I have a problem with wifi connection on Honor 8 (FRD-L09C432B399, EMUI 5.0.1) - I have no problem to connect to wifi networks, but wifi is spontaneously shutted down regardless of whether I am connected or not on router/modem. The wifi switch is still on (blue), but all visible networks disappear, the phone disconnects from the connected network, and it takes a few seconds before the phone finds networks again and automatically connects to the known network. I made a factory reset, but without success, rather it seems to me that the situation has worsened and wifi fails nearly every 10 seconds.
Any suggestions how to fix this problem? Thx.

Are you sure, 'Keep wifi off, during sleep' isnt set to 'Always'? As you already have resetted to factory set it shouldnt be. Although please verify.
Yes, it is; also 'Wi-Fi+' is dissabled.

WiFi problem connecting and disconnecting

I have a very annoying problem in My Mix 2s, the wifi is disconnecting.
I have already updated the miui, downgrade, I used the miflash, I installed the beta version of miui.
I recorded this video to show how the wifi :
watch?v=aspqbGUar6Y
Note: When I am downloading the wifi does not disconnect.
Is there any way I can tell if the problem is hardware?
there any fix for this problem?
