I purchased this broadband modem from rogers to support my 25 MBPS service.

The only @#$%%$ thing is that rogers doesn't give you the full configuration password to configure the settings of the device, only a basic config for wifi, etc.

Here are some of the user names that work with read/only and config passwords for the Gateway that may be helpful for you.

user: cusadmin
pass: password

user: mco
pass: cxf1rst

user: rogcesadmin
pass: wra8uje

Hope this helps someone.
