I need to configure about 25 computers to use our wifi network so I would like to copy the settings to a USB drive and install them from there. On my Windows 7 machine when I go into the wifi properties and select "Copy this network profile to a USB flash drive" the next window opens that says "Insert a USB flash drive into this computer, Plug in a USB drive to continue". I plug in my flash drive it gives a message that the driver is installing and I can see it in Windows explorer. But the "Next" button on the "Copy Network Settings" window stays grayed out and I can't continue. I know I've done this in the past on this computer but I can't get it to work now. I tried this on two different windows 7 machines with the same result. I've tried 2 different USB drives - same result.
