How to update modem firmware

Your modem's firmware is the software that is installed and controls it. To maintain modems operating at their peak performance and provide new features, firmware is updated on a regular basis. Through the Brightspeed network, updates are carried out automatically, so you typically never have to worry about them. If your modem isn't functioning properly, you can log into the modem settings and make sure the firmware is completely up to current. Before you begin, bear the following in mind:


• For the most dependable internet connection, we advise using an Ethernet cable to connect your device directly to your modem. You can use a wireless (WiFi) connection if this isn't an option.


• You do not need to first make a backup of your custom modem settings because updating the firmware will not wipe them out.

NOTE:  Depending on your model, your modem's user interface may appear slightly different from the images below.




  • Operating System: Windows 7 Pro 64-bit 


  • Processor: Intel® Core™ i5-3320M CPU @ 2.60GHz (4 CPUs) 

  • RAM: 16 GB 

  • Network adapter (naming device varies): 1000 Mbps, 1000baseTx, or GigE 

 5.  Select "Upgrade Firmware" in the left sidebar.

  •  If it says Firmware is up to date or N/A, you don't need to update. You're all done! You can log out and close the modem settings page.
