I've had an Airport Extreme in our home for a couple years now, and havent had any issues up until a couple months ago. It seems like all devices connected to the WiFi network now seem to timeout when pretty frequently when trying to load a website, and when the sites do load it seems to take forever. I've tried power cycling both the modem and the router multiple times without success, and have changed the wifi channel from Auto to Manual, and have selected several different channels...without success... Anyone experience this or have any tips?? Thanks!
