This is not happening only to IE. It happens also to my Mozilla Thunderbird e-mail client and the Bittorrent torrent application.
I have to close the network controller on the network centre screen and re-open it to work for some time before it freezes again.
In line with David: get rid of any and all torrents you may have. They tend to work well to start with, but they only cause trouble. Download programs for torrents are also hazardous. It's all a big bunch of creeps who act as friends but they only look for their own "some" advantage. Been there, experienced some.
