In rare situations, you may have bridged your modem. If you can't access your modem settings through http://192.168.0.1, try the following:
1. Press the reset button on the back of your modem using a paper clip or pen tip until the power light turns red.
2. Wait for the internet light on the front of the modem to turn green (5-7 minutes). Now open up a browser and finish setup.
3. Check your modem's Utilities menu for the latest firmware version. You will be able to upgrade from there if needed.
4. If you want to bridge your modem after the firmware upgrade, follow the instructions on the WAN settings page.
If you are a CenturyLink internet customer and your modem isn't listed in the table above, contact us to ask about upgrading to a newer modem.
