Channel 149 and 161 Connection Timeouts

Reported by: Dakman05@… Owned by: developers
Priority: normal Milestone: Designated Driver (Trunk)
Component: kernel Version: Trunk
Keywords: mt76 Cc:

Description

When in client mode (sta) and when connecting to ASUS RT-AC56U Router, and when broadcasting a 5G 802.11ac access point on 161 or 149 (VHT80) MT7612E/ MT76 fails to connect.
The only way to use 149 or 161 is to force the AC56U to transmit on VHT20/VHT40 . All other channels work great:

36 (VHT 20/40/80 OK)
40 (VHT 20/40/80 OK)
44 (VHT 20/40/80 OK)
48 (VHT 20/40/80 OK)
149 (VHT 20/40 ONLY) - 80 NOT WORKING!
153 (VHT 20/40/80 OK)
157 (VHT 20/40/80 OK)
161 (VHT 20/40 ONLY) - 80 NOT WORKING!
165 (VHT 20/40/80 OK)
