I have an early 2008 iMac (24", 2.8Ghz Core2Duo, 4Gb RAM) with OS X.5.8. I've recently installed Vista Ultimate (32-bit) via Bootcamp. We're staying in my parents' house for 6 months because we're renovating our house. In our room, we don't have an ethernet connection, so I'm using Airport to go on to the net (they obvioulsy have a wireless router). The thing is, in OS X, wireless reception is excellent (all 5 bars are filled), whereas in Vista I only get 1 bar. Maybe the bootcamp drivers aren't good enough for Vista. In Vista device manager, my airport card shows as a broadcom card. Is it safe to update the drivers on the vista side ? Same goes for my ATI radeon HD 2600 Pro (which shows up in device manager as a ATI Mobility Radeon 2600 XT). Can I update drivers without causing problems to my configuration and to the "OS X side of things" ?
