Is this a bad time to point out that you could do this on Untangle with no other hardware required? Just sayin’.
Syslog?
Sent the logs over last night.Did you manage to get the logs over to Glenn? It does sound like a possible HW issue though.
I got to the point last night where I reset the unit, deleted the wifi config from the controller and configured it again. Same signal power, same channels, same SSID, same passwords and things are better. RX Frames on the unit are 50% on the 2.4Ghz band.
Meant to have a look at retries this morning, but didn't have time.
