Buy another Ethernet card. It's cheap.
Personally I got a good one for 15$. Now you can get it for 10$ there: New Intel 8390MT PWLA8390MT 1000 MT PCI Desktop Adapter - eBay (item 250643221285 end time Jul-31-10 11:50:34 PDT)
This may solve your issue because the drivers are well supported in Win7 (the pro category is always better for drivers).
go to network and sharing center click change adapter settings select your card right click properties click configure card go to advanced tab and make sure receive side scaling is disabled.
