Just installed OpenWrt 22.03.3 on Archer A6 v2.0 (US) Latest version, OpenWrt 22.03.3
The 2.4Ghz works normally - (Qualcomm Atheros QCA9560 802.11bgn) - picking up dozens of nearby APs
The 5GHz though - (Qualcomm Atheros QCA9886 802.11acn) oh boy - just seeing one or two very near APs when I'd expect dozens based on experience with similar routers in the same place.
Do I have a dud, or could it be the driver or something else? I tried it on the driver that comes with OpenWrt 22.03.3, and also updated the driver as recommended to the commerical driver - same range of APs available.
Oh I see, I thought you were asking if the 5.4GHz was connected to another AP or client during the scan.
I've connected to the router using both Ethernet and 2.4Ghz and 5GHz connections and scanned - not by serial though.
web GUI for the scan - LuCi
Thanks for this - look like the 'lower RSSI signal' might be the problem which I guess is not solvable. There's a few comments about how the 5ghz signal is weak.
It might be that the router i'm comparing it to just has particularly good 5ghz performance and my expectations were too high.
