[Q] Wifi problem on CM 10.1 based rom (MIUI)

I know there has been a lot of wifi problems with Dlink Dir-655 and I9505. While on TW rom's i solved this using a guest wifi in the router.
Yesterday i flashed MIUI that is based on CM 10.1 (after flashing a stock rom and wiping everything). Wifi works great at work and when trying tethered networks using wpa2, non broadcasted wifi's etc but at home it doesnt even try to connect to either one of my networks.
Is the wifi problems the same for CM based rom's? I was under the impression that the wifi driver would be different than samsung stock and therefore not have the same issues? Or is it a HW issue? Any workarounds possible?

Been googling/searching all over the place but can't find any answers (looking mostly for wifi issue on CM as MIUI is rather uncommon).

Wireless keeps disconnect after downloading cm 13.0

Hey
I was using phoenix rom and everything was okey but after the cm, wireless keeps disconnects like every 20 30 seconds.Is there anyway to fix this? i dont want to back to my old rom.
Also i full wiped before dowloading cm 13.0 and searched through the forum but couldnt find an answer.
samsung s5 g900f
update:i think i have fixed by changing my wifi setting/channel to use only 2.4ghz.

Happened to me also yesterday,was annoying a bit,but fixed itself after i rebooted my phone,you can also try that if 2.4ghz doesn't work in the future

4G/LTE not working on cm 13 based roms

Hello, I've tried a lot of cyanogenmod 13 based roms, even cyanogenmod itself, and 4G never worked on any of them.. I'm on g900f, tried changing apn and it didn't work anyway, any help?

No one knows anything? I've tried AOSP roms, and they don't have LTE working for me either..

Make a clean installation of the latest CM13 SNAPSHOT, I used to have the same issue on the late nightlies but the Snapshot fixed it.

I tried that, but as soon as I flashed a custom kernel it stopped working.. Any ideas why?

I'm on latest 6.0.1 original samsung rom update, and lte/4g option is gone, there is just 2g and 3g options... Also gps is buggy when you turn it on, it automatically sets to high accuracy for spying...

I had to return to stock because lte only works during the initial configuration on AOSP Roms.. That's strange. On stock 4G is perfect..

Cyanogen Mod 13 and 12.1 WiFi Issues (Samsung Note 4 SM-N910G)

Hello.
I have recently installed CM 13 on my Note 4 (SM-N910G). I know that CM 13 isn't officially supported for the Note 4 but i flashed it. The issue I am having is with WiFi. When I try to turn on WiFi the switch in settings is greyed out. While doing the initial setup at the connect to WiFi page it said Turning on WiFi continually. Is there a fix for this??? I also flashed CM 12.1 which is officially supported for the Note 4 and had the same issue. If i restore to the Samsung ROM through TWRP Recovery the WiFI works fine. So is this a ROM issue in CM 13 and CM 12.1 with the Note 4???
Any help would be greatly appreciated.
Thanks.

Probably upgrade your bootloader a d modem : https://forum.xda-developers.com/showthread.php?t=3273816
CM 14.1 (Now called lineage) is out since a while and 910G roms are becoming stable if you want to give it a try.
I'm on dpl1 bootloader and dpk2 modem on my 910G and I don't have any troubles with WiFi in recent build (Stock/Ports/lineage 14.1)
using 910G / Govtuner 3.8

Maybe this is ur problem

I found the problem,it was my wlan encryption mode.
It didn't connect with WPA2 +WPA3 (FritzBox), WPA2 only works.
Thanks for the help anyways

My redmi note 8 has the same problem but it's a little different, it doesn't even turn on wifi and mobile data, it keeps activating infinitely on any android 11 rom, it only works normally on android 10 :/

The issue is regarding either your wifi or the ROM which you're using , (since lavender doesn't have A11 update officially by Xiaomi) , So you can try flashing the fastboot version of latest miui fastboot ROM , and then flash your ROM again , it should fix the issue if it's from your side. If not fixed then contact your maintainer.
