I'm using the linksys befw11s4 router with the latest firmware installed. For maybe a year or so I haven't had any problems with it. However, maybe about two months ago, whenever any of my pc's on my network attempts to access msn videos or mtv overdrive, it never connects. Whenever I try to browse the net afterwards, I have to unplug the router and plug it back so I can surf the web again. Is it time for a new router?
