I received my Intel 5350 adapter and all day I've been trying to get the Intel Proset software installed - getting nowhere on the WiMAX part. I'm running Windows 7 on the Mini 9. Intel doesn't have Win7 drivers for the 5350 yet, but I've read that the Vista drivers might work. The WiFi portion is functional - I get a good wireless connection, but the WiMAX drivers will not install and the Intel Proset setup ends up rolling back the installation. This seems consistent with what I've read on other threads where people run into a dead end trying to get the WiMAX working on the Mini 9. Or maybe it's a Windows 7 thing, I'm not sure..
