Limited Bandwidth Uploading

[websolutions]

My situation:
- 4 computers on a network
- computer 1 uploads a file to computer 3 at a rate of 1.5 MB/s (byte)
- computer 2 uploads a file to computer 3 at a rate of 0.3 MB/s
- all computers are using Windows 7 Professional

I think I remember having to somehow disable network throttling on computers #1 and #3 at one point, but in trying to recall what I did through searching Google, I found nothing but content on the Multimedia Class Scheduler, which wasn't it, and some other things that weren't it either.

Besides throttling, are all the ethernet controllers the same speed?

All computers have a Broadcom NetLink (TM) Gigabit Ethernet card. Computer 2 was originally connected wirelessly at 54 Mbps, but I switched to the wired, thinking that it may be that, but it wasn't.
