Wireless printing with AT&T U-verse and 3800...

Question

I have been set up on AT&T U-verse with a 2Wire 3800 HGV-B. I have a Wireless printserver by Linksys WPSM54G. I was able to print wireless until I switched over to U-Verse. I am having trouble setting it up again. I did some research and found that the wireless network key on the 3800 HGV-B is to be used for the WEP Key. The installation program for the printserver picks up my 2Wire but when I get to the end to be wirless it does not connect. Am I using the correct number? Do I input it as a Passphrase or WEP key?
