skycrew:

I try to configure 5ghz wireless on my archer c7 v2, unfortunately it seems unable to use the 5ghz.

I have no issue with 2.4ghz wireless.

dimberr:

looks like the driver is looking for firmware "firmware-6.bin" and board file "board-2.bin" in /lib/firmware/ath10k/QCA988X/hw2.0/

In that directory there is only "firmware-5.bin" and board file "board.bin", so changing the name of this files helps to interface up and wlan0 starts working.

however I get that output:
