Not sure if this is related but I have issues with my Dynalink DL-WRX3 5Ghz networks
I just upgraded from 23.05.2 to 23.05.3 stable
After upgrading and restoring my Config Backup Archive, I had an issue where the WiFi networks were present but not enabled. I enabled them, but then only the 5G raido 0 was active. If I clicked restart on the 2.4Ghz radio 1 it would not activate.
I then reset my router at System>Backup/Flash Firmware
(A full reset may not be necessary, maybe try deleting and recreating your wireless networks first)
And recreated my networks
After enabling my 2.4Ghz network Radio 1 automatically became active and same goes for 5Ghz Radio 0.
But, networks created on 5Ghz Radio were not visible to any devices.
However! I don't know if it's just my devices, but Radio 0 5ghz has never worked properly with my O-WRT. Not in 23.05.2 either. Even when radio 0 is on, my devices can't detect my 5G SSID.
The first time I installed O-WRT My 5Gz network worked for moments (devices connected) and after a reboot (or something I'm not aware of) 5G networks wouldn't show again on any devices scanning, and then I disabled the radio.
Don't know if this is a known issue, let me know if I should start a new thread for it.
