Hi Arjav,

Are you really using a real OpenWrt?
The presence of the "wigig-firmware" package makes me suspect that
you're using the "QSDK" fork instead. In that case, you should probably
ask QCA for support instead. We won't be able to help you properly,
since the system that you're using is very heavily modified in many ways.
