do change wep key

I just installed Beta 2 and am trying to connect to my wireless network. My laptop detected my network and asked me to put in the key. I accidentally typed the key in wrong, so it obviously won't connect. Where do I change the key it has stored? I can't find anywhere to change the WEP key it has associated with my network.

I just installed Beta 2 on my laptop. When it booted into Windows, it detected my wireless network and asked me for the key. I accidentally typed the key in wrong, so it obviously cannot connect. How do I change the WEP key it has associated with this network? I cannot find anywhere to change the key it has stored.
