John,
Something is out and about and playing with routers as I have a regular client with the BitDefender suite (including the firewall) and a router and something got onto her laptop and caused all sorts of flakey behavior prompting her to bring it to me. BitDefender's logs show it had said some king of a major struggle with some version of QHost but seems to have brought it under control just about the time she gave up and brought me the laptop (because I couldn't find anything wrong with it).
However, her she discovered that while her old laptop would do Email, it wouldn't do the web until after she called me up and we tried several things before getting round to rebooting the router which fixed the problem. I myself had no trouble here as long as I had her notebook connected wirelessly. When I connected it by ethernet for a big download, then a little later I started to get poor net behavior -- a ping would time out, take a long time, time out, take a long time. I thought it was just RoadRunner being flakey but it was still doing the same the next morning. I'd already tried hard-resetting the modem and it didn't help, but after I hard-reset my router suddenly everything was back to normal.
I've had this router several months and never had to reboot it -- curious indeed. So, I'm doing a double, double check of her system but so far everything I've thrown at it has come up with nothing except a few cookies.
