Linksys Wireless G Router Model WRT54G

It didn't work for me.
Should the username be the email address from At&t that controls the DSL line, or should it be the username to get into the Netopia modem?

k so u moved to AT&T-DSL-so u have a user name and password right then the authendication method is different let me tell u the connection
AT&T-DSL-modem--->inter net port on the w/l router>and one of the ether net port on the router to ur pc(or)laptop>
and open an explorer browser screen on the pc and in the address bar type-192.168.1.1>hit enter>and
user name-- admin (lower case)
password-- admin (lower case)
and u can see the setup screen>
there change the (Automatic Configuration -DHCP)--to PPPOE
u can see a different screen where u need to enter the USER NAME >AND PASSWORD WHICH U GOT FROM UR AT&T
AND CLICK ON SAVE SETTINGS>AND REBOOT THE ROUTER AND MODEM>AND U CAN ACCESS INTER NET AND IF U WANT TO USE WIRE LESS GO TO THE SAME SCREEN LIKE 192.168.1.1>WITH USER NAME AND PASSWORD AND GO TO WIRE LESS SETTINGS AND CONFIGURE IT
rate me solved if its help thx

You need to set your Netopia for "Bridge Ethernet"
