Have you called Rogers to have them check the signal strength and S/N ratio, or do it yourself? These sorts of issues can be due to a marginal signal on certain channels. The higher QAM frequency channels are usually the first to go.
SS should be above -10dB and preferably close to zero and not above +10dB. S/N ratio should be above 33dB.
The issue could either be inside the home our outside in your neighbourhood. As temperatures drop outside (or inside), sometimes the connections outside can be marginal as the metals contract and the signal can come back as temperatures rise and the metal expands again.
A poor signal is the cause of the vast majority of these sorts of issues. Can you temporarily remove upstream splitters, or move the equipment closer to the demarcation point in your home to see if that has any effect?
there is an opened network issue and it was a confirmed transmission issue and not signal related.ticket ID is C116768405
Seems to be working here.
1. Make sure your cable connections are tight.
2. The local feed is also available on channel 191 in Ottawa - does it work on that channel?
3. To get a quick weather update, use the "D" button on your remote to activate the weather app.
Black Channels (if the channels themselves are "transmitting") are usually the result of a poor signal in your home or neighbourhood. Here's a post on that topic. You can call Rogers to have them check the signal - they can do this remotely, or you can check the signal on that channel yourself, per the link:
Most people today use the internet or an app to check the weather, either by phone, tablet or computer. Here are a couple of links for the Ottawa weather:
