Cannot activate Wifi on hallon (cm-10.2_hallon-LX-20131013-NIGHTLY.zip)

[kitabema]

Wifi cannot be activated on current hallon build (button in settings is grayed out). I don't know for sure but if I remember correctly with "cm-10.2_hallon-LX-20131001-NIGHTLY.zip" it started not working (previous CM 10.2 builds had working Wifi but (a lot) other issues).

Last (more or less) fully working build (for my hallon phone) was "cm_hallon-LX-20130925-NIGHTLY.zip" (CM 10.1).

Some logcat output (complete file cannot be attached here...):

Use the kernel from the zip.

I did use the (appropriate) kernel from the zip file, I always do. Am I the only one with that problem?

Did you clean your (dalvik-)cache-partition? I had that kind of problem some time ago ... i forgot to clean the caches after flashing a new version, maybe it helps you too.

[mikeNG]

Every "Cannot activate Wifi" bug is a problem of the user not following the installation steps exactly. I test wifi on every single build before releasing. It always worked since my first builds on March.

[kitabema]

I'm a software engineer myself and that could be my words to our quality assurance. ;) I did clean up (wipe) caches (including data) and I'm back to "cm_hallon-LX-20130925-NIGHTLY.zip" - wifi working again.

Only problem I can think of is that I save settings on my Google account - including wifi settings. Perhaps that's the problem: restored wifi settings from cm 10.1 on cm 10.2?

If you try the latest build again, get a dmesg log too so I can get more info. Usually when wifi is not working there is some problem with the wifi modules not loading

Problem solved.
I did lot of thinks to solve it. Factory reset didn't work. I delete adb-bundle and I downloaded it again. I installed the flashtool-driver again. I deleted Google Account Settings.
I took the same boot.img, flashed it again and now Wlan works fine!

Original comment:

Exactly same problem here.
I flashed the right kernel from the zip, had no problems while flashing.
I also wipe data and cache before i installed the zip.
My SD Card was in the beginning complitly empty and i also think the save settings from Google account couldn't be the reason, because it didn't work even before i could login into my Google account.
One Minuat ago, i deleted the settings on my Google account (including Wlan password), wiped cache again and restarted the phone - same problem, the wifi button is grey and does nothing.

I could create a dmesg log, can you say me the command line, wich you need, because i don't know much about dmesg and what you need.

Though trying "N2Blue"s suggestions unfortunately it does not work for me,

wl12xx: ERROR could not get nvs file ti-connectivity/wl1271-nvs.bin

[kitabema]

What does that mean? I had installed the latest ICS firmware before trying FreeXperia and
afterwards your builds. My current baseband version is 8x55A-AAABQOAZM-203028G-77.

There's something wrong with the calibration file, it's missing. It should be there, it seems that somehow the calibration script isn't getting executed

[kitabema]

#101 seems to be similar. I did not test without google apps.

[siyman]

As stated in this comment (#123), I also executed /system/bin/wifical.sh as root and rebooted. Afterwards I could login to my wifi again. I did everything as expected in the installation guidelines and haven't had such problems before.

[adrientetar]

I confirm this and has the same problem as @siyman. Still occasional dropouts after flashing but they're sparse and short compared to e.g original CM10 kernel. Maybe fixed with latest wifi changes? Not reflashing for now personally.

[kitabema]

With MT11i (Neo V) ftf flashed on my Neo (MT 15i) - not so easy to accomplish with Windows 8.1 (not working at all) and Fedora 19 (a bit tinkering with flashtool start script and libusb necessary) - Wifi is working fine again.

Therefore this issue can be closed in my opinion.
