Updated my EA8500 to 22.03.3 from 22.03.2. Kept settings. Same packages installed in both cases (I use the firmware selector to build my images). It's used as a dumb AP and switch.
Not a good result. 5GHz WiFi speed to a desktop PC client (AX200 2x2 WiFi card) dropped from ~340 Mbps to ~110 Mbps. I reinstalled 22.03.2, and WiFi speed went right back up. I measured WiFi throughput from the PC client to my NanoPi R4S gateway with iperf3 on a quite network in both cases, back to back with less than 10 minutes separating the measurements.
More detail: AC, Channel 149, 80 MHz Wide, WiFi SSID bridged to a VLAN (several VLANs are trunked into the AP).
Edit:
With no other similar problem reports, I concluded the poor throughout I observed must have been user error - something like all my clients jumping on the AP after upgrade. Who knows? In any event, I tried upgrade to 22.03.3 again on my EA8500 and it is working just fine.
