I've just bought a new computer with a 64-bit Windows 7, and I can't get online with it because my old Retail Plus IEEE 802.11b/g Mini Wireless USB Adapter, which worked fine with my old Windows XP computer, doesn't seem to be compatible with my new one. I've plugged in the adapter and used the setup CD, but whenever I open it it just seems to appear in the Superbar for a second, then dissapear again. I've tried switching it's compatibility to Windows 2000 and such, but nothing works. I have a D-Link 524 router downstairs and the Microsoft website says it works fine with 7. Should I buy a new adapter? If so what ones work with Windows 7? Or is there something I need to download online for it?
