I'm on what is currently a 2 person network... Just used for simple home connectivity. Both computers are using Windows XP and LinkSys 100tx network adapters. My hub is a 5 person 100mbps non-switching hub... Decent setup. My problem began some number of months ago actually, but I haven't paid much attention to it since the network is used primarily for gaming. When I DO copy files however, I'm getting something like 10mbps transfer rates. Perhaps even slower. I've wondered if the hub is auto-sensing one or all of the network cards as 10mbps, because I can't find anything else wrong and the problem goes largely unexplained. A few months ago, I was copying 100mb files in a matter of seconds... Now it takes roughly 10 minutes (On a good day!). Both of the computers (while copying files) have been idle. Also, both hard disks are very capable... No local disk or disk controll problems.. And judging by the disk activity LED indicators, they are both not even close to load while copying is in progress. I wanted to ask if anyone else has had this happen, or if anyone has suggestions as to what could cause this so that I might be able to fix it.
