Never set up wireless internet on a PC before, but this was very straight forward. I've got a Virgin Super Hub and Windows 7, and this works perfectly. You'll need to load the driver from the PC (unusually Windows 7 didn't find it), but don't bother with their software, as Windows 7 is all you need.
Took my PC downstairs to test the signal strength and it's also showing as excellent, and having used an ethernet cable for yonks, I can barely notice a difference in speed too. For 9 quids this is a bargain! Excellent product and would recommend if you have a similar setup.
