What is that? Is it some external hard drive that connects wirelessly to the computer, or are you talking about a USB Wireless Adapter?
If it is a wireless USB adapter, why do you need it on the two newer Windows 7 laptops? Do they not already have wireless connection inbuilt?
I have a wireless USB connection I sometimes use & works well on my laptop running with XP OS, but when I tried to install on 2 laptops running Windows 7 OS, the USB installs but will not connect i.e. - does not initialise.
When USB is connected i show a blue light, this is showing but set up box on screen says no service. Both these laptops are newish ( under a year old ) Is there a problem with Windows 7 OS & some software ?
