TJ, thanks for your support on this. I will definitely try what you have mentioned.

Just looking for one piece of clarification. If those tests were done while directly connected to the modem, would the first hop then be the 'modem' rather then the 'router'? (Probably is I just want to double check)

I've been starting to think it's either an issue with my pc or modem but obviously wanted to double check with some experts on here before I go order another modem.
