@CindyW67 -- has Shaw recently replaced your cable-modem, or installed a signal-amplifier to boost the signal, or has a Shaw technician done a site-visit to trouble-shoot your issues, or when you have telephoned Shaw Support, have they done any remote trouble-shooting?
No, I have not reached out directly to Shaw yet. Actually thought it was a television issue but have recently realized it happens to both tvs in the home. I will be reaching out to them soon, when I catch the system in this loop and can call in the moment.
