I have a Virgin Hub 3.0 as my router and an Archer C50 as an access point connected by ethernet.
Occasionally the AP will lose connection to the router. At that point I have network connection but no internet. This is the case for all connected devices. I cannot ping the IP address of the router (192.168.0.1). I can log into the AP, I cannot see any errors. Sometimes the clock has been reset to 1970 but this does not seem to relate to the issue.
If I reboot or restart the WAP it reconnects to the router and everything works fine for a while. Then, after a time (30 minutes - 2 days), it loses connection again.
I've tried giving the AP a static IP address (reserved at the router). I've tried getting the AP to reboot in the middle of the night. I don't know if the issue is at the router side or the WAP.
Any suggestions would be greatly appreciated.
