WEP only client

I have a client whose wifi adaptor (Linksys WUSB11) can only do wep key encryption and I was wondering whether it would be possible to use eap-tls or something similar given the restrictions. What is the most secure system that can be used with this type of adaptor? -- Ian Truelsen s/v Sting Email: ian.truelsen@gmail.com AIM: ihtruelsen MSN: ihtruelsen@hotmail.com Google Talk: ian.truelsen@gmail.com
