My desktop PC is plugged into the LAN port of the repeater and my modem/router is plugged into the WAN port. The repeater is running in router mode, using the same SSID for the wireless network as the router/modem. This has worked without issue for several months , but all of a sudden, and without making any changes, there is no WiFi signal from the repeater. If I reset the repeater and reconfigure it, there will be a signal for a short while before it drops. I have also tried just switching the power to the repeater off and on again, and the signal was available briefly before disappearing again. Any suggestions would be appreciated.
