Bit torrents killing my internet?

Nothing to do with your bandwidth. It's the size of the routing table like Wikipedia says.

My router's a BEFW11S4, but still, if upgrading the firmware will fix the problem, I'm willing to try it.

I found a firmware update for it, but unfortunately, it only gave my the .bin file, and all their instructions involve using some executable that's supposed to be included in a zip with the .bin.

Is there a general way of upgrading firmware that somebody knows about?
