Live TV channel 21.2 and 21.3 keeps dissapearing
I have two OTA channels that sometimes get duplicated TV guide info from the base channel (eg. channel 21.1 will show the same info for 21.2 and 21.3 even though they are different channels). The other day I noticed that channels 21.2 and 21.3 were not showing up anymore even though they are programmed. I then disconnected the ethernet cable so I would not have an internet connection and saw that the missing channels suddenly came back. Plugging the ethernet cable back in then re-established the internet connection and then removed the channels again.
I suspect that whatever duplicate channel guide issue is happening for those channels is now causing them to be removed when the TV has an internet connection as it is only those two channels this is affecting. Is there a fix for this? I have already restarted the TV several times and reprogrammed the channels several times with no improvement.
