I want to change the SSID and password on my Technicolor CGM4141. If I do that will my wireless cox tv boxes still work?
Turn off your router and test for TV programming. If no programming, you'd need to update the network setting on your cable box.
Also, what portion of the service is wireless?
I assume there's a coax from the wall going into your modem. Is the TV signal from the modem to the cable-box wireless?
Or is your cable-box connected to the wall coax (splitter) and the signal is wireless from the cable-box to the TV?
What's the make and model of your cable-box?
