How do I find out my WEP key?

Fennec asked:


I have a wireless Linksys modem but I didn’t set it up myself.
How do I find out what my WEP key is (I need it to play online on the wii)
My serial number and ‘Mac’ number are both 12 digits.

Also, when I go to my security settings on IP address all it has is firewall settigs, additional filters and the ability to block WAN requests
Got it, thanks!
