Some of the admin utilites allow these keys to be viewed. I hope you mean WAP and not WEP. If you are the only uses of the wireless, it may not be setup. Just login and and set the wireless up from scratch.
There are utilities like "ariskkey" ( will need to google if needed) that allows you to view what is hidden under arisk text. It does not work in all conditions. If you have access to the wireless setup, it may work.
I find it easy to easier to use notepad, create the key then copy and paste, eliminates typo's, particular if they are true random text and long, 64 chr.
