Someone Help please

[wireless]

First off we had Internet 25 and then we switched to Internet 75 because it had a better offer for the pretty much the same price. As soon as we got the new internet there were problems. Disconnections through the day like every 20 minutes. Cant even run certain sites like Twitch or Crunchyroll. I cannot play games that would run perfectly on the old internet League of legends, any steam game and not even runescape. I have talked on the phone for 6+ hours with telus service and have had a technician come 3 times. He blames the game servers or my setup even though the old internet ran everything perfectly. The dude literally comes and shows me speedtests and tells me its fine (same guy every time). I have tried different channels, tried stuff with the firewall, different routers. I don't know what to do please help. Heres a trace route from the game with shows the worst(I think).https://bhzof35755.i.lithium.com/t5/image/serverpage/image-id/7813iDCA38A8C26CE0748/image-size/large?v=1.0&px=999
