https times out after using utorrent for a while

[ioi101]

So I've been having this odd problem for a long time (2-3 years). After utorrent has been on for a while (~5-10 mins), I cannot connect to any websites that use https (i.e. basically anything that requires a logon). Everything else is fine - speed, browsing non-https websites, etc. It looks like recently google search goes through https in some way because it's messing that up, which it didn't use to a few months back.

Reseting my router fixes it, and I'm guessing it's a problem with the router. I'm pretty sure it has nothing to do with my comp (I had the exact same problem on my old winXP machine and now on my new comp with win7). I messed around with some utorrent settings - lowered the global connections, etc, but that doesn't seem to do anything

Also I tried using azereus for a little while it seems like it doesn't have this problem, although I'm not certain, it may only happen with seeding many torrents (I only tried one as a test).

Any ideas?
