@BertEpp -- I think the problem is with the Blue curve modem!
Verify that the coaxial-cable between your BlueCurve and your wall-port is tightly-connected at both ends. Also, try a different coaxial-cable.
If that does not help, then note that this is a peer-to-peer discussion forum, not a path to Shaw Support. So, I recommend that you contact Shaw Support (currently, online chat has priority over telephone) and get them to trouble-shoot. They can remotely logon to your BlueCurve, to verify the incoming signal-strength, which may be the problem.
