Enable High 5GHz Wi-Fi Channels on CyanogenMod 12 & Cyanogen OS 12 (CM12S)
(and potentially other OnePlus One ROMs too, subject to testing)
Here in the UK I have a Wi-Fi router running on channels 136+132. This worked fine on CM11S when the phone was new out the box, but with CM12 I was unable to see (or connect to) the 5GHz network. It would only show the 2.4GHz network, as my router separately broadcasts 2.4 and 5GHz networks.
After messing with various modems and Wi-Fi drivers, I found that extracting the CM11S Wi-Fi drivers and Qualcomm configuration files and placing them on CM12 worked perfectly fine, and my phone can see my 5GHz Wi-Fi now.
I have no idea which channels are now enabled, or whether this will work for you, but do give it a try. If anything messes up just dirty flash a CM12 nightly or CM12S stock zip over the top to restore.
Download and flash the zip attached in recovery.
Thanks go to the CyanogenMod / OnePlus Teams. I didn't create these drivers or configuration files - I just extracted and tested them, and made the flashable zip.
Tested on CM12 nightly from 4th April, and CM12S released on 14th April build 12.0-YNG1TAS0YL.
Please post your results on this thread, ensuring your state which channels your Wi-Fi router broadcasts on. This way I can track which channels the phone has enabled under which circumstances.
Good luck!
