Successfully managed to upgrade to the latest and just finished the factory reset, everything working great. Thanks again for fixing the issue.

No worries. I will check and report back soon, thanks for your time.

I am currently connected via the R2 over WiFi. I am not sure about the model number exactly, but manufacturer is Arris and was provided by Shaw (Hardware Information: BlueCurve Gateway (shaw.ca)). I will try to put R2's IP in the modem's DMZ. EDIT: DMZ has been enabled for the R2's IP from the modem provided by Shaw.

Done.

I am unable to upgrade the firmware from the 3.0.179 that came installed when I bought the router. I tried installing 3.0.205, 3.0.394 & the latest firmware 3.2.453, all fail at the end of the upload process. Inspecting requests on the browser window reveals that the router seems to be rejecting the upgrade with a 400 Bad Request with what appears to be missing auth_token cookie being sent with the request. What am I supposed to be doing here to fix the issue with upgrading my router?
