Keeping your set-top box or Android TV device running optimally often requires a firmware update or reinstallation. If you are looking for a Technicolor DWI259S Go to product viewer dialog for this item.

Once the router stabilizes and the internet light turns green, log back into the web interface ( 192.168.1.1 ).

If the GUI rejects the file, the download may be incomplete. Delete the file, clear your browser cache, and download it again from your ISP.
