I have 18 Mbps cable internet, though I notice that right after a restart it won't do it. Only after its been on for 20-30 minutes. If I went to purchase a nic card how will I know if it has interrupt capability? Edit Actually its a bit faster according to the test: http://www.speedtest.net/result/1454906788.png It does seem that it got worse with the speed upgrade, previously I had 6Mbps and it was not as bad. Also, it only happens with web surfing, not FTP, torrent, games or http downloads.
