Slow transfer wired comp to server no middle man

Im upgrading my system to windows 7 64 bit and im running 32 bit vista so i needa back up my files. so my dad has a 1TB raid 1 server i believe and i hardwired it to my comp via ethernet cable. My mobo says its transfer speed is about 1gigabit/sec? which my dad says is bout 120 MB/sec so i should be transfering at that speed or like 100 but im transfering at like 8MB/sec... can someone please help me out i dont no why this is. Also when i open task manager and go to networking it says Adaptername: Local Area connection. Network utilization: ~7%. Link speed: 1 Gbps. State: Connected

Also this is just another question i had i used the Windows 7 upgrade advisor and it says im compatible for 32 bit everything except my wireless netword card (its a 802.11g Wireless PCI card made by Texas Instruments, so its pretty old )and in 64 bit it just says compatibility unknown. do you guys think itll work...cause i really dont want to spend money on a new network card=\ Also im running a 2.6 GHz 9950 black edition AMD CPU incase you were wondering and 2gig of ram but plan on upgrading so figured id put 64 bit on now.

Thanks in advance,

John
