I have a 5 year old Linksys wireless router (G, I think) connected to a cable modem (that I replaced with today through my ISP in an attempt to fix this problem).
The problem: For 5 years I have had no connection issues but over the last 2 months the I can only maintain my internet connection for about an hour at a time on any device. The connection to the router is always present but the internet connection is lost. If I power down the modem and router then the connection returns for another hour. I have changed the wireless channel twice on the router but have done nothing else to the router in the last 5 years.
I'm ready to go buy a new router tomorrow but thought I'd ask for some advice before dropping the money on something that may not fix the problem.
