I have a Linksys WTR54G router. At just some random point in the day, my internet will stop working. When I ping the internal address of the router, it just times out. If I release and renew the connection, it will not reconnect. The WLAN l.e.d. light on the router also is no longer lit. My solution thus far is to turn off the power switch on my surge protector that has my router and modem plugged into it and turning it back on again. Any idea what's going on?
