@eksc -- check Shaw's web-page for the TM602G hardware:
https://support.shaw.ca/t5/home-phone-articles/hardware-information-arris-tm602-phone-terminal/ta-p/...
where it says that the Ethernet port and the USB port on the back are DISABLED. Sigh.
So, you cannot "start" with this device.
What is your current wireless network adapter? Does it connect to Shaw? Telus?
