Internet comes in through my furnace room

Kitchen right over my furnace room

TV drops ocassionaly in my living room and main bedroom

Okay i think i’ve covered most of my issues here

I have a gaming router which hard lines into my pc and a couple other areas in my basement. I wanna find a good mesh system to cover all my areas and stop the freezing of my streaming channels. Any advice would be appreciated.
