Applied on 5.19 and worked. AP: QCA9984 STA:AX201 Before patch: iw dev wlan-ax201 link rx bitrate: 866 MBit/s VHT-MCS 9 160MHz short GI VHT-NSS 1 tx bitrate: 866 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 After patch: rx bitrate: 866 MBit/s VHT-MCS 9 160MHz short GI VHT-NSS 1 tx bitrate: 866 MBit/s VHT-MCS 9 160MHz short GI VHT-NSS 1 Notice that the tx rate did not change and the NSS reduced from 2 to 1. But actually it should support VHT-NSS 2 and achieve 1733 MBit/s at least for rx bitrate (verified this with the same AP/STA using another OS, and iperf showed 1.2GBit/s). Do you have any idea to fix that? Although it is beyond the scope of this patch. with iw 5.19 ax201 showed VHT RX highest supported: 0 Mbps VHT TX highest supported: 0 Mbps VHT extended NSS: supported
