Hello 7 users I too am suffering with wireless conection problems under win7 beta. I have beta7 on a test machine with the following spec: GIGABYTE GA 7N400L-1 M/B AMD 2400 CPU 1 GB RAM NVIDIA 7300 GT 40GB HDD D-LINK DWL-G122 WIRELESS G USB ADAPTER In device manager there are 3 devices with a problem. nvidia nforce mcp networking controller. multimedia audio controller. sm bus controller. I haven't found a suitable driver for these devices as yet.Still looking. Everything else seems to be working properly. I do have onboard sound working in a fashion.(Its a bit crackley).It wasn't working at all before i downloaded and installed a newer AC97 driver from Gigabyte website. I'll worry about that later. Wireless. The D-Link usb adapter shows up in device manager and is working properly. When i try to connect i see a list of connections with my seimens router (supplied by Orange) with mine at the top followed by a number of other connections which i imagine belong to other users in the neighbourhood.(Netgear42,Cougar2500,BTHomehubA34D). I click on my router name and enter my SSID (on the bottom of my router)and it tries to connect. The lights flash on the usb adapter a few times then i get a message to say 'unable to connect'. Have tried various driver updates to no avail. On my router,Broadcasting is 'ON'. Any suggestions would be greatly appreciated. Thanks and good luck with win 7.
