Wifi configuration for Pine phone

[suren21]

The driver should try to load the required file from a path under /lib/firmware. In pmOS I have /lib/firmware/rtlwifi/ and /lib/firmware/rtl_bt/ containing a number of firmware files, supplied by packages linux-firmware-rtlwifi and linux-firmware-rtl_bt respectively. I don't know exactly which ones are used by this driver, or whether there's an interaction between the wifi and bluetooth drivers. You may need to check the distro bug trackers to see if there were any fixes for wifi problems in case there's something unusual they have to do to make it work reliably.

Ok looks like the driver is getting loaded. I am able to use iw tools to see the available SSIDs in range. 
Also able to connect to open networks. 
Error is only for WPA2.

Any idea what could be the problem

thanks
