1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.
3. Log in to the modem's online user interface (Modem GUI) using your Administrator Username and Administrator Password. Unless you have changed the default settings, you can find this information on the modem's sticker. Note that these are different from your wireless SSID and security key.
4. Select "Utilities."
5. Select "Upgrade Firmware" in the left sidebar.
6. Check the "Upgrade Status" area:
If it says Upgrade Firmware, proceed to step 7 to upgrade the firmware.
If it says Firmware is up to date or N/A, you don't need to update. You're all done!
7. Select "Download."
8. Select the drop-down next to "Save" and select "Save as."
9. Select "Desktop" (or choose another folder if you prefer), then click "Save." The downloaded firmware file should now be saved on your computer.
10. Now to install the saved file, select "Browse" on the Upgrade Firmware screen.
11. Navigate to your Desktop (or the folder location where you saved the file in step 9). Select the firmware file, then click "Open."
12. Select "Upgrade Firmware."
13. The screen will show you the progress of the upgrade installation. This step will take about 2 minutes.
14. Next, you'll see a screen telling you that the modem is rebooting. This step will take about 3 minutes.
15. Once the upgrade is complete, you will be taken to the main "Modem GUI Login" screen. Wait 2-5 minutes for the DSL and internet lights on the modem to turn green before trying to access the internet.
