I was setting up a friends net connection for them and saw that comcast gave them a wireless Linksys cable modem/router. Well if it was just like all the other linksys routers the default password for the routers webpage should be "admin". It was not (big suprise). Comcast has had someone (linksys?) modify the firmware for them for this router. It has been stripped down to a very basic set of things you can do. Problem is the set a username an password for this router/modem and it was not a linksys default password. After some searching I finally come to find out the login id is "comcast" and the password is "1234". If you do a hard reset of the modem (little black button on the back of the unit) this is what the default userid and password will revert to.
