“Telmex Infinitum-branded router for Mexican home internet — unusual in that the admin username is the fixed literal string "TELMEX" while the password reuses the device's own WiFi label password rather than a separate admin credential.”

How to log in to the Telmex Infinitum WS880

  1. Connect to the Telmex Infinitum WS880 by Wi-Fi or a network cable. On a phone, turn off mobile data.
  2. Open a browser and go to 192.168.1.11.

If the login does not work

  • Check the label first. This model has a unique password printed on the device — admin / admin will not work.
  • Someone may have changed it. A factory reset restores the login above.
  • Reset: hold the Reset button for about 10 seconds while the device is powered on.
  • Wrong address? Check your default gateway — see how to find your router’s IP.
  • Type http://, not https://, and turn off any VPN or Private DNS.
