Upgraded to internet 150 now Roku TV cannot connect to internet - Telus Tech is at a loss?

[wireless]

I had no issues with my Telus internet 50 but was offered an upgrade to 150mbps (pure fibre is not available in my neighbourhood at this time.)

I had no problems before the upgrade and I have added no new items. The new faster internet was not as good right from the start... noticeable on Roku TV when streaming, slow when checking email on computer, gaming on PS4 etc. Telus Tech comes out and tests it and says it's all great and running like it should. A few days later I call the tech back because things are even worse - he tests everything, replaces the modem and adds Telus Boost.

Now Roku TV connects to wireless but cannot connect to internet at all. Tech tests the Roku TV by setting up a hotspot on his cell phone and it works immediately. The Roku TV does not have an ethernet port so connecting through wireless is the only option.

I contacted Roku who says it's your ISP's problem.... Telus knows it worked flawlessly on internet 50 but has no clue why it won't work with internet 150 and says maybe it's Roku's problem - HELP!?
