I doubt its a DNS problem, all TELUS Optik customers use the same DNS servers, if they were bad all customers would be having issues and I assure you that is not the case. If your internet is slow or unstable its probably going to be a service call to get to the real cause, regardless of how the TV is looking.
Have you tried another PC, do you have someone who could bring their laptop over and see how their PC surfs? It could be your PC has aquired a virus, or has an issue. If you can connect another PC this would be a sure way to check your internet's performance.
Good ammo to have when you call up for service too, if you can say "its not just my PC either no PC has good internet when connected" this will get you through the troubleshooting stage alot faster with the CSR
