3Com

3Com Login Username and Password

Use this page when you know the router brand is 3Com and need the default login credentials before changing settings.

How to use 3Com default credentials

Match the model and IP address before trying a username/password pair. A shared brand can have several defaults across model generations.

Find the router model on the label or in the browser title of the admin page.
Open the matching router IP address from the table.
Try the most specific row first, then broader rows only if the model is unknown.
Change the router admin password after a successful login.

FAQ

Are all 3Com routers using the same password?

No. 3Com routers can vary by model, firmware, ISP bundle, and region. Use the model/IP row as the source of truth.

What if the default password fails?

The password was probably changed. Check the router label or ISP documents before doing a factory reset.
