@bdobson -- for what I can tell is a problem within the Shaw network itself
Looking at your packet-trace:
I see a 15% packet-loss between your computer and your cable-modem. That is definitely not normal.
Try a different Ethernet cable, or, if you are using WiFi to connect to your cable-modem, switch to using an Ethernet cable, and rerun the trace.
Or, try running the trace, using a different, Ethernet-connected computer.
I've tried multiple cables, I don't use wifi for my computer as I don't trust it enough. The only thing in my apartment that uses wifi is my iPad and iPhone that's it.
This is not a problem on my side, it just went away and guess what it's back again.
I'm not sure they'll be any better but I'm seriously eyeing Telus at this point to give them a chance because this is irritating. I'd call support but that will lead me to the same things I've already done as they don't troubleshoot anything (not their fault).
To be clear on this one just in case.
@bdobson -- two thoughts:
