I currently have an Arris cable TV set-top box (HMC-4000) from my cable TV provider, which allows me to watch TV programs on the same WiFi network without competing for the TV with my family. This is a great feature. However, due to WiFi security concerns, I need to separate the WiFi network from the local area network. Could you please advise me on how to use an app to specify the IP address of the set-top box, instead of relying on the app to search for the set-top box within the same local area network? Your assistance in resolving this issue would be greatly appreciated.
