I've got an iMac and an eMac connected to a Linksys wired router (BEFSR41). When I'm downloading a large video file (movies and such) on one computer, surfing the net comes to an almost complete halt on the other computer. Is this normal? I'm using DSL and download speed is around 1.4 mb when I'm not downloading large files on one computer. I've already returned one router for replacement due to other issues so I'm wondering if I got another lemon. Thanks very much for any help.
