Channels pixeling

[Debp4897]

I have seen many people post on here about higher channels pixeling. This is happening at my home as well. Seems to mostly affect those that are part of the Discovery family. In the evenings it is worse than during the day. My cable was ran to my house 17 years ago. It happens on every TV and all my connections are secure inside the house. Nothing new or has changed. How do I convince Xfinity to send someone to check the outside line.

I have the exact same problem here in Illinois! It hits mostly between channel 150 and the upper 200s but definitely the Discovery channels and especially TBS and FX. It also takes out the HD feed of our local ABC channel (187). Starts around 5:50p and keeps it up until about 11p. The rest of the day, the channels are fine.

It's been happening for about a month and seems to be getting worse. At least now I know I'm not going nuts.
