@shotty_workmens -- there are several "points of failure":
- your Shaw cable-modem and/or Shaw TV box
- the coaxial-cables inside the walls
- the coaxial-splitter inside Shaw's "demarcation" box (where the Shaw cable comes from the nearest telephone-pole into your residence)
- bad connections at either end of that cable between the "demarc" box and the telephone-pole
- the Shaw infrastructure along the telephone-poles
I recommend that you contact Shaw (1-888-472-2222) and book a service call. Also, the Shaw employee can remotely logon to their cable-box, and view the "signal strength" reaching that box. Having a weak signal can cause your issue.
