I don’t know too much about routers and how wifi works, but my parents bought a “gaming” router a year back or so and it’s been absolutely amazing, even all the way from my room which is at the opposite end of the house. Thing is, when I’d take some time off from college to hop on my Playstation, the TV in the living room would lag when they tried to watch football or movies so, one day they messed with it somehow. They made two wi-fi networks to connect to: “Template” and “Template5G” and they said they’re moving the “better wifi” to 5G and only the TV could use it. It worked for a while but now… goddamn. A 10GB update for a game I have takes 3 hours or so now. Even the TV doesn’t work and the wifi is just super slow and sometimes will spike and completely not work from time to time. I even recommended to my dad that maybe if we put the router higher in the room, we’d get better connection? So, they taped/nailed it behind the top of the TV and called it a day. Anyways, I need some help… I don’t even mind if ya’ll use words I don’t understand, I’ll learn. Thanks for reading ;

Edit: I don’t know if this is important but it also sttes we have “weak security” under our wifi networks.

TL;DR my parents messed with some wifi settings and now it doesn’t act right/it’s slower for everyone
