Wifi on Cyanogen issues

I just finally got sick of waiting for an official Froyo(Bell isn't about to give me an upgrade anyhow.) So I went to a froyo rom that was based on one of the stock roms. But I figured since I'm rooted anyhow why not play around, and grabbed cyanogen 6.1 and installed it. Then I end up with the issue of its not connecting to my wifi, I have no issues on the stock 2.2 roms. One thing I have noticed is the cyanogen shows the network as wep, but it's actually wpa encrypted. I flashed into it from the stock without clearing it first and it worked until I shut off and came back to it. Any ideas on what might be the issue. I'm fairly new but I did look and couldn't find anything to fix this.
I assume you flashed 6.1 stable version? I have no issue whatsoever on my device (and I also used official froyo previously). Did you wipe all before flashing 6.1?
He said he "flashed without cleaning"...so I presume no wipe. This could be the problem, a wipe is strongly adviced if going to CM from a non CM ROM. Also check the number of WiFi channels set by default in advanced settings of wifi. It is set for 11 and if the router is set to 13 or 14 it could not work

I had the same problem when i was installing CM6.1. (with wipe)
The phone could just se a wep version of my network and not the wpa that i have. But after i turned on and off the wifi a couple of times i suddenly saw the wpa version of my network and after i connected to that the problem was solved. I also did click "forget network" on the wep version.
Hope this will help you

Trying this now but no go. Sometimes will flash it as wpa and then jump back to wep. This is after a full wipe. What I was trying to say was once I flashed in without wiping and it worked for a bit but jumped right back to not working, after the phone going to sleep.
Bump.
Any insight into this issue? Still only reading my network as wep.
Try installing "WiFi Advanced Configration Editor" from the market. You should be able to change to WPA manually with it.
Did you try to reset your wifi router?sometimes the issues came up from wifi router, not the phone itself.
Mine is fine. I share my broadband wifi to my phone using connectify.
The only problem remains is wifi disconnect frequently, but I heard that it's due to a new kernel which I use (.32 kernel)
hope it helps
Ya reset the router a few times, and it still came up like that. I did install the wifi advance config software mentioned it seemed to fix it. I didn't actually set anything up on it and it seems to have fixed it. Thanks.
CM 6.1 messed up my wifi. Wiped everything, but it suddenly doesn't find my networks.
Wiped again and restored nandroid backup of working rom but STILL the same issue now!! Can I flash the wifi drivers again somehow?

WiFi activation loop

Hello everyone,
I flashed CM 10.1.2 with build-date 2013 Jul 11 and I can't activate my WiFi anymore.
Bluetooth is ok, but I can't disable NFC - same as WiFi.
I push the button and it's "working" to activate wifi or deactivate nfc - but nothing happens. [edit: nfc working after reboot]
I've got not many ideas what I can do. Everything is working fine with the stock rom v.20a EUR_Open.
Has got someone an idea what I can try?
I did every step on it's own to have a look on which point the problem appears - after installing cm 10.1.2 with cwm recovery.
Bootloader is unlocked.
I'm looking forward to your suggestions and please accept my apologies for my bad english.
Kind Regards
FChaos
For nfc, just restart once, that will fix it
Hey,
im having the same issue with wifi.
When i try to activate the switch gets stuck in grey but it does not activate.
I have it since I installed CM 10.1.2 stable. Before everything worked just fine.
Any solutions for this problem?
Greetz
Wipe cache & dalvik cache
Fix permissions
Reboot
If that doesn't work then full wipe and reflash.
Note: WEP encryption will not work with CM v10.x so make sure you are using WPA on your wireless networks.
I already tried everything you mentioned, but nothing works for me.
WEP is not the problem, because I can't even get to the point to select my router. Also I'm using WPA2 at home.

I presume the CM build you refer to is a nightly? Try a different one or CM stable - nightlies are a beta software and may have random bugs.
The problem occurs since I installed the CM 10.1.2 stable.
After that I also tried some of the new CM 10.2 nightlies, but the problem still exists.
Any other ideas?
Edit:
When I install Android 4.1.2 Stock everything works just fine, but the moment I install CM wifi does not work anymore.

Serious Wifi problem.

I have had this problem ever since I installed my first rom (FreeXperia unofficial cyanogenmod 11) and stayed ever since
The problem is that every time I try to connect to my home network it will say "saved, secured with wpa" but never connects.
so far I have tried:
Forgetting and re-adding
Factory reset
Flashing different kernel
Flashing different rom (Vanir and official AOKP)
unchecking wifi-optimisation
changing region.
Non of these work, somebody please help me figure this out
P.S it also happens on WPA2 but less.

Wifi woes with the Z3 Compact

Hello all,
Just having an issue with my Z3 compact. The wifi keeps connecting and disconnecting every few seconds. This is a new development and it has never done this in the two years I've owned it. It finds the networks, connects and then promptly disconnects after a few seconds and then starts to look for networks once again.
Here are a few things I've already tried....
I have tested the same WiFi network with my S7 and laptop and they are stable on this network.
I have tried a different WiFi network with the same results
I have downgraded to a previous TWRP backup of my ROM when the phone was still stable.
I have changed the ROM completely with a factory reset and new custom ROM flash
None of the above has worked so far so not sure what has happened and if this is a possible hardware failure of the modem? Is there a modem file that could possibly be flashed?
Thanks for the help.

This has been mentioned several times in the Q&A thread, and @toxic-hero even posted a fix
Thanks Didgesteve,
I have tried the Legacy DHCP Client fix in the developer settings and I've also done a "Network settings reset" under Settings > Backup & reset before rebooting and still no help. The issue persists and I'm at a loss as to what the hell has happened here....
Same problem... I still have guarantee, so I flashed back the original up-to-date firmware and the phone was sent back to the local sony service, and I'm waiting for it.

WIFI stucks on "Obtaining IP-Address" after Flashing

Hi.
I've used my Mi5 for two month with the Global Dev Rom, no Problems.
Then I wanted to try Lineage OS, unlocking and flashing was fine but when I wanted to connect with my Wifi, the Phone can't obtain an IP-Address.
Meanwhile I've tried everything obvious: Restart the Router, try to connect with other Routers and WIFIs, Flashing other Roms (Lineage, miui.eu, cyanogenmod, china stable, china dev, global stable, global dev), others Kernels - everything works but the WIFI
Has someone an Idea whats wrong with my Phone?
Thanks for Help!
i dunno if this will helps.
Go to etc/firmware/wlan/qca_cld/ and rename wlan_mac.bin to wlan_mac.bin_bak.bak
Hope it helps!
Have you tried connecting to some other wifi ?
Same issue. My wifi only works on official MIUI and on .eu (haven't tried any other MIUI roms). However, on Havoc, Pixel, LineageOS.... nothing. Its able to find the networks and attempt to connect but theres an authentication errror (password is well written tho) and it can never connect. Just like you, I have tried using different wifis (even without password), reset router, change wifi channel, 2.4/5ghz, different firmware for the phone... nothing seems to work.
Any idea?
PS: the antenna and the charging port flex on the device has been replaced because it didnt have good cellphone reception, so it might not be the original from xiaomi. Im not sure if this might be causing the problem.
Thanks for your help!
