I had 3 computers on a network and my friend decided to download something. All of a sudden, no one was able to access the internet and resolve any host until after he finished his download. What happened? And is there a way to stop that from happening? That was the first time, but I suspect it may not be the last. I am using a 2wire router.
Update He was downloading something from MediaFire, I believe. It was not Bit Torrent for sure. It was a direct download. It started happening a while after he started the download, but as soon as his download was finished, we were all back able to connect to the internet like instantly.
Update It seems it has happened again. This time, I was just one YouTube streaming 1080p. No one was able to make new connections, as in they could not visit a website or connect to AIM, etc... Do you think ISP is tampering with connection? I am not a heavy downloader, but I have downloaded before without any problems such as this.
