Archer C7 v1.1 wifi issue

Hi There, i'm new on the forum.
I have a Archer C7 v1.1 router and i put OpenWRT on it, version 15.05.1.
I saw on the dedicated page that the 5GHz card doesn't work, the problem is that neither 2.4GHz does.
I tried to connect via SSH to the router, and executing the ifcongif command the output doesn't show nothing else than eth0, eht1, lo, br-lan devices.
Obviously i can't see trace of wifi cards even using the web interface. For example, there isn't the voice "Network/Wireless".
