Telmex / Infinitum — Login and Wi-Fi Setup Guide
Provider-supplied gateways can vary by model, region and firmware. Start with the label on your installed equipment and use the customer account or local administrator account intended for that task. A provider subscription password, a Wi-Fi key and a local management password are not interchangeable.
Telmex provides an official service for changing the Infinitum Wi-Fi name and password. Use that customer workflow or the instructions for your installed modem. Confirm that you are changing wireless settings rather than the Internet service account; different supplied models can have different local menus.
Open the correct management interface
Connect to your own device's main Wi-Fi network or an appropriate LAN port before opening its management page. The address shown here is a starting point: use the current gateway, device label and exact model documentation to confirm it.
- Check the complete model and hardware revision on the label. Keep the administrator account separate from the Wi-Fi key.
- Open the documented address in the browser address bar. If the LAN address was changed or the device is an access point, check its current assignment on the upstream router.
- Sign in using the password you created during setup or the model's documented initial process. Do not assume admin/admin applies to a newer device.
Change the Wi-Fi name and password
Open the wireless settings for the intended network, select the correct band or shared Smart Connect network, then edit the SSID and wireless password. Save the changes and reconnect your devices. A wireless change can end your current session. Keep a wired connection available where supported.
If the page does not open
Check the active connection's address, subnet mask and gateway. Guest isolation, an upstream router or a VPN route can prevent management access. A failed browser request does not identify a device or prove that a password is wrong. Use the exact model instructions before changing addressing or resetting anything.
Keep Internet settings intact
Back up the configuration where supported and make one change at a time. Preserve provider connection details, VLAN and telephone settings. Restarting and factory resetting are different actions; use a reset only when you can restore the configuration or the provider has instructed you to do so.
