I know it's not supported but for anyone on CM13 I gave it a go. On the A3000 I didn't have WiFi. Just thought I'd let anyone considering testing it what I found.
Not surprised, WiFi is going to be problematic on this phone. They've built the driver as a module and did not release the source.
Right now I just hacked the kernel so the stock module will load, because I don't want to modify the system partition and break OTAs.
The WiFi driver source is sort of available from CAF, but we don't know if they've added any proprietary stuff to it or which config options are used.
It makes me wonder what else could be different or missing in the source code that has been released.
You guys should bug OnePlus to release their source properly. As it is, I'm not impressed and this will be the last OnePlus device I buy.
