Thanks for the reply. I am doing this for my better half's new Surface and need a lot more help, I guess. I have a Trendnet 452 brp working here and her laptop is connected wirelessly to it and working fine. Surface is next to it on the desk. Went to Network and Sharing Center. I don't see a 'connection' to click on to get to a 'details' button to get the MAC address (MAC addresses are used for filtering access). The only MAC address that I found was for Marvel Wireless Network Controller. I doubt that is the correct one for the Surface. The name of the wireless connecxtion doesn't show up in the list of available connections nearby, and I don't understand why or what to do about it. Your help will be greatly appreciated.
