My ax86 arrived today, got it set up and everything on WiFi was slow. Investigating it looked like everything was connecting at 802.11n. Didn’t matter if it was 2.4 or 5 GHz. After a lot of trial and error, I found a fix, on the Wireless settings, Professional tab, set Modulation scheme to up-to MCS11 and OFDMA/802.11ax MU-MIMO to both. Did that to both 2.4 and 5 and speeds picked right up. Maybe it’ll help you too. I attached a pic of the settings.
