They track torrents and stuff you download now and if you go over a certain amount, they'll slow down your connection. I doubt that's what it is since your connection is cutting off too though.
I did but I don't think that's the problem since my connection cuts off at times. I tried upgrading the linksys firmware, which I haven't upgraded since I bought it a long long time ago but that didn't help either.
