My wireless isn't working?? help?

I've been looking around online trying to find help for this but I can't find what I'm looking for....

My wireless has worked in the past, but isn't now. I haven't used it in a while. Apparently my dad changed the settings to WEP. Would that be a setting you change on the router or how does that work? I tried changing my settings to WEP as well.

here is a screenshot

I read somewhere that my WEP encryption strength needs to be the same as the network or whatever I'm trying to connect to...however, I don't seem to have that setting option, as you can see above....(I think it should be 64bit or something?)

Another thing is, my computer doesn't even seem to be able to SEE any available networks? My dads laptop works fine, so the network IS working....

Any ideas?

Nevermind. Apparently I'm just a little slow :o The wireless radio wasn't enabled :o
