I have installed several devices on my wireless network and I am confident about the basics of MAC addresses, encryption and suchlike. However, I followed the instructions to the letter with this device and could not get past the point in the installation where it asked me to attach it to the computer. I tried downloading drivers from Lynksys' website but met the same problem, and spent 25 minutes (at 10p per minute!) on the helpline - again, with no success. Nothing worked. I suspect it is something to do with the 64 bit architecture on my new machine? Returned for a refund and bought a Belkin USB wireless stick that took 5 minutes to get working. Avoid.
