It seems that my Archer C7 v2.0 (S/N 2167193001064) running trunk r50108 (needed trunk to handle new flash chip) does not know how to talk to the 5GHz wifi chip.  I can't figure out what's up with the ath/ath10k drivers, since they seem to be built into base-files.  Installing kmod-ath doesn't work since it seems to come installed.

Still, no dice.  No extra messages, either.

Hi flash to LEDE 17.2 and all will be good.

I really enjoy the stability and support of OpenWRT.   It raises another question:  why was there a departure from OpenWRT for so many people?

Also, it was solved now.  I have no idea why ath10k isn't in the main archer c7 v2 trunk or available by opkg but, you can apparently get the ath10k packages manually from the snapshots ( https://downloads.openwrt.org/snapshots … ar71xx.ipk ) download and install manually and everything works smooth as butter.
