Hello,
Thank you for posting in Microsoft Community forum.
Based on your description, we suggest that you try the following methods to re-establish the connection between your desktop computer (Windows 10) and the TV's set-top box.
Firstly, ensure that your desktop computer and set-top box are connected to the home broadband modem and have a normal network connection. Check all network cables and connections to ensure they are not loose or damaged.
Secondly, on the desktop computer, open the network settings, search for available networks, and try reconnecting to the set-top box. Ensure that you have entered the correct network name and password (if any).
Then, make sure that your desktop computer and set-top box are both on the same LAN so that they can communicate with each other. In Windows 10, you can view and change network sharing settings through the Network and Sharing Center in the Control Panel.
Finally, try mapping the network location so that you can access the network shared folder in File Explorer. You can try the following steps:
Open File Explorer, select the "Computers" tab, and then click "Map Network Drive". Enter the network path of the set-top box and follow the prompts to complete the mapping process.
If none of the above methods can solve your problem, we also recommend that you try contacting Fetch TV support for a solution. Please refer to:
