Rogers Ignite Downloading PC Game TV Stops Working

So it is 1:30AM EST and no Internet traffic. My ISP provider is bad and gives bad advice to fix problems. Anyway problem below ,I am just showing when downloading PC Games my TV's do not work. Picture freezes and no sound.

Advice I got from ISP ,well best answer I ever got was to turn off and unplug TV's and Xi6 Wifi and WiFi pods .Running one TV and one Xi6 at 1:30AM still sucks.

Downloading PC game,TV not working,pause downloading PC game, TV working. Funny how that works.

Gear
Ignite Internet 150u
XB6 Modem- Hardwired to two computers
Xi6 4 WiFi pods to 4 TV's
VOIP Phone

Problem-

I play PC games and I need to download these PC games from Steam/Orgin/GOG/Uplay/EPIC/RosckStar

When downloading PC game my TV's stop working and phone stops working because I am using all the bandwidth from downloading a PC game. I do not want to compromise my Internet download speed for these games.
Rogers has no answers but to say unplug TV when downloading.
