Home network transfer speed is slow. Help.

[lauroy8]

I have two NICs in my main PC, one is connected to the DSL and the other is connected to a 4 Port 3Com hub for connection sharing. When I transfer files from the main PC to the other computers it goes fast as expected. But when I copy files from one of the other comps back to the main PC the "!" light on the hub goes on solid and transfers are very slow. I have tried different NICs and still have the same problem. It is entirely possible that I am just stupid and have configured something wrong. Any help would be appreciated.

Thanks

Doubt it was intentional, go easy on the n00b.
