I found a manual here: Siemens Manual

The condo we've rented for the winter for the past few years has DSL. The owner has it set up as an open system, probably so week to week renters in the summer aren't bothering him for login instructions. When we checked in, I logged in to the router and checked for users. There were 34 people using this one account (think of the computer savvy 14 y/o to the nth degree)!

I promptly set up the router with my own id and password, then set up the wireless connection as secure. Of course, I had to reset everything when we left, but no biggie.

On a forum I found an entry which said the default id for the Siemens is "admin" and the password "telus". These, of course are the entries you'd want to change to keep out the 14 y/o.
