Received a new Rock 5A board, 8 GB. Booted Debian from SDcard, all ok.
Then inserted an USB WiFi dongle to connect to my home WiFi network.
It worked, to a point. Every about 10 second there is a message telling that the network is disconnected, but immediately after it reconnects. All ok for about ten seconds, then the cycle repeats…
Understood, I had misinterpreted your suggestion.
But the problem is that going to the shop, I come back home with the dongle in my pocket.
Ordering the M.2 WiFi card from Radxa I will have to wait a few weeks for it to arrive from China…
