#20986: 5ghz not functioning on Archer C7 v2 with 15.05 factory bin
----------------------+--------------------------------
Reporter: spam@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: packages | Version: Chaos Calmer 15.05
Keywords: ath10k |
----------------------+--------------------------------
I've just installed
https://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/openwrt-15.05
-ar71xx-generic-archer-c7-v2-squashfs-factory.bin
onto my Archer c7 v2. The wifi interface will not come up. Luci gui says
it is enabled but has 0% tx power.

I've done `opkg update && opkg upgrade kmod-ath10k`. Not sure what else
to do.
