I have had this problem for a while now across at least last 3 firmware updates. The 5Ghz WIFI radio drops out and is no longer discoverable, logging into device shows 0% signal and all clients disconnected.
2.4Ghz radio works fine, no issues.
This isn’t an interference issue, and I also checked that the channels were not set to auto so not selecting DFS as I thought they may be disappearing due to interference.
Only way to resolve it is to reboot the device, but this is happening daily.
It’s like it’s switching off and no longer working, I have tried long periods of not rebooting to see if it will sort itself with no improvement.
I’ve tried different antennas to rule out this issue but nothing seems to work.
Sometimes 36 hour pass and think I’ve solved it then happens again.
Tried fully flashing unit and starting again, doesn’t fix anything.
Could this be a faulty unit as it doesn’t seem to be firmware dependant and secondly after speaking to my supplier no one else is having the issue.
The WiFi on the 5GHz has always been slow on this router, if I connect via the Ethernet port and get 400gbps the wifi will only do 60-80gbps, which has always struck me as odd.
Maximum number of clients on 5Ghz is no more than 6 at a time.
Any suggestions would be helpful.
