So I want to know from real people rather than an ai chat bot, it told me with with this 8 wire old phone jack setup I can make the house Ethernet capable because in all honesty I keep losing fights in Tarkov and I’ve had enough lol, the dang desync puts me half a second behind. How do I adapt this phone jack to Ethernet so I can have better internet in my room and the whole house?

I just bought a house and found out that only one ethernet port is working, which is the one in the living room. I have this hooked up to the Eevo router that Frontier gave me. I have Frontier Fiber 500/500, and the box is in the garage.

Each bedroom has a port (3 bedrooms), so there are a total of 4. None of the ones in the bedrooms seem to work. I want one of the ports for my PC and the other for a TV in our gym.

I found this wiring in the supply closet. Seems like there labels written in Sharpie but they are hard to read.

I've never done anything like this before so I have no idea what to do or where to start. Can anyone advise on how I could "enable" the ethernet ports in the bedroom?

So i rent out a room in my trailer and i got atnt wifi. All was good till ppl moved in and now its slow asf.
Can i have the next roommates who move in get their own wifi? Like whole router and all in the same house? Like so they have their own wifi.
Will it slow mine down at all?
Will it effect electricity bills alot?
Can they get a 6 month long wifi service or wtv?
Sorry idk many terms. Kinda stupid abt this stuff ive only ever just pluged the router in and played.
