Hi all, I'm having an intermittent issue where all LAN ports on my 2860 stop responding about once per week. When this happens all devices connected to LAN (2 PCs, VOIP phone, Xbox, NAS) loose all network connectivity. Tried setting manual IP address on a PC - still couldn't ping the router. LED lights on LAN ports keep flashing normally. Devices on Wi-Fi are not affected. To resolve the issue (until next time) I have to reboot the router. Any ideas?

Maybe a dodgy PSU? When the ports stop responding, are they slowing link lights/link speed, etc?

Just happened again LED lights next to ports look normal, activity lights flash randomly. Dashboard in the GUI also shows that all ports have connection . In reality, only Wi-Fi devices work.
