OpenWrt "Chaos Calmer" 15.05 released

Where does it say that? For the Archer C7, I think you're supposed to use the v2.0 revision. The page says that 5 GHz WiFi is not supported on the C7 v1.x and the WDR7500 (== C7R) v2.x, but is on the C7 v2.0.

From the link:
> The Archer C7 v2.x uses the BR4A (v2) variant which is supported in ath10k.

Gotta love router vendors and their cute naming schemes.
