I have 2 computers on a wireless network with a WEP shared configuration. I have a 26 hex character network key. Now my stepson wants to put his computer on the network. He has a notebook with built-in wireless. I go to the wireless network, right click on advanced and click on WEP and shared. Then i type in the 26 characters but it only allows me to type in 24 of them. So how can i enter the key and get him on the wireless network? what am i doing wrong?
