Just a quick entry to check if others are observing the same (will add troubleshooting data later)
I’m running a Rock Pi 4 (1.3 hw) with the latest Ubuntu Server image, and I’m planning to use
it headless. The board is connected via WiFi, the router is located on the same floor (i.e. well within an acceptable distance, i.e. more or less optimal conditions)
In AC mode, the connection is not stable at all …a ping to the gw will show highly variable RT-delays, and the connection drops.
in 11n mode, the connection remains up, but an active SSH session to the board (openssh-server) shows very bad “reactivity” … characters entered will not be echo’d for several seconds (especially after some idle time) etc, something which is typical for frameloss & retransmissions … …I never observe this on a Raspberry Pi, connected over the same Wifi network & located even further away.
Does anyone observe the same ?
