This is a supportive statement to someone else's tip, If you are running and older machine and do not have Windows vista as an OS and are running XP compatible hardware. I went out and bought a Dynex NIC card model DX-E102. IT works with Win7. Also AVG free edition is compatible with Win7. It is obvious that if you can't get on the internet then you can't download updated drivers for your original NIC card or wireless adapter. Even if you have another machine to use, the Vista or updated drivers are hard to find if at all. The card can be purchased at Bestbuy for $18.00 or online. Just Google it and you'll find the answers. Good luck to all.
