WiFi infrastructure: 5x Ubiquiti UAP-AC-Pro, firmware 4.0.54.10625 With an Intel AX200 [I think also with 9000 series, but don't nail me to this] iwlwifi is sometimes spilling my dmesg with "Unhandled alg: 0x707" on a WPA2-PSK/CCMP ESS. But only if I am connected to 5GHz. In dmesg you see it stops if I roam to 2.4GHz, but starts again as soon as I roam back to 5GHZ. Throughput on 5GHz is thus limited to some little kb/s. bssid / frequency / signal level / flags / ssid f2:9f:c2:f8:c6:f4 5180 -59 [WPA2-PSK-CCMP][ESS] AGuest f2:9f:c2:f7:c6:f4 2412 -48 [WPA2-PSK-CCMP][ESS] AGuest After 15 minutes it suddenly stopped. I tried roaming again.
