Oi Fibra Modem Login
A complete guide to the Oi Fibra modem admin panel — covering the login page, default credentials, Wi-Fi name and password changes, and what to do if the modem page does not open.
This is not your modem’s admin page.
To open the real modem interface, enter 192.168.1.1 directly in your browser’s address bar while connected to the same Wi-Fi or Ethernet network.
If the page does not open, make sure you are connected to the correct modem and that the address is entered without extra spaces or search terms.

If the login page does not open
Having trouble accessing your Oi Fibra modem settings? Connection issues, rejected credentials, and slow-loading admin pages are common problems. Below are the most frequent issues and how to fix them quickly.
⚠192.168.1.1 is not reachable
Make sure your device is connected directly to the modem, preferably via Ethernet cable. Double-check the address for typos. Try restarting the modem and wait about 30 seconds before trying again.
⚠Login credentials are not accepted
The default credentials may have been changed by you or your ISP. Check the sticker on the back of the modem for the current password. If it was changed and you cannot remember it, a factory reset will restore the defaults.
⚠The page loads very slowly or times out
Disable any VPN or proxy settings on your device. Try a different browser or use incognito/private mode. Clear the browser cache. If you are connected via Wi-Fi, try using an Ethernet cable instead.
⚠Wrong IP address?
Some devices use a different default address. Try these alternatives: 192.168.0.1, 192.168.100.1, 192.168.1.254. You can also find the correct gateway address in the network settings of your operating system.
⚠How to reset the modem to factory settings
Locate the small reset button on the back of the modem (you may need a paperclip). Press and hold it for at least 10 seconds until the LEDs start blinking. The modem will restart with the factory defaults, including the original login credentials.
