I've been having intermittent disconnects from my router recently. I though it was my network card acting up, but now I'm not sure what is going on. Sometimes, the router disappears for a minute, sometimes 5, and it recurs sometimes every few minutes, sometimes not for hours. The weird thing is that when it disappears from my list of wireless access points, all my neighbor's wifi disappears too.
So that had me thinking my network card was the problem, but since my roommates have this issue, maybe it's Comcast's problem. On the other hand, I also have had issues where I'm still connected to the router but I have no internet access. In those cases, not only can I not access the internet, but even the router's internal web interface is unreachable. Resetting the router has fixed the former problem, but not always the latter...Any ideas?
It's a Linksys WRT54G with the most recent firmware by the way
