Peter,
Shaw has changed their signal encoding from MPEG2 to MPEG4, while this has not affected a home system it has affected Trav'ler models manufactured before November of 2017. We are working on an update kit for affected systems. That kit is not available yet, but we are hoping to have it available in the next week or two.
At this time what you have done to get signal is the only way to get signal until the update kit is released.
Thank you,
