Help finding a driver for a 2701 2wire internet router?

I just got a new computer, which a friend of mine built, the only trouble is, i can't seem to find a driver for my adapter! I'm using an ethernet connection, not a wireless one, so i figured the drivers would automatically install, but no such luck...i've checked the 2wire website, but it only seems to have drivers for every other model besides mine. Any way, i'd be eternally grateful if someone could help me find this elusive driver. I've already looked a good bit, but to no avail. Once i have the driver, I believe I just have to transfer it from my laptop to my new computer via flash drive. Thanks for any help!
