Change the default password after logging in

Default credentials for Comtrend routers are publicly documented, so if your router still uses one, change the admin password immediately to a strong, unique password. Leaving the default in place lets anyone on your network reconfigure the router. Many newer Comtrend models instead ship with a unique password printed on the device label - if yours does, use that.

How to log in to your Comtrend router

Open a browser and go to http://192.168.1.1, then sign in with the credentials above. For a step-by-step walkthrough, see how to log in to 192.168.1.1. If you don't know a changed password, you can reset the router to restore the default.
