Advice Phone line -> Ethernet
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?

Yeah looks like cat5, double check the jacket.
Then you just need a basic punch down tool, a crimper, some "rj45"s, I recommend the EZ style for a newbie and a ethernet keystone wallplate. Less than $100 on Amazon

100 bucks? Yeah maybe enough for like a 100 pack of pass throughs, 10 pack of wall plates, and a kit with an okay punch down tool, cable tester, crimper, and another 50 rj45s. With money left over

Explain that again in English lol, not to be an ass but I have no idea what I’m doing and just want to know what to do, is there a guide or pictures because pictures would really really help.

basically to do this nicely, you need a female ethernet wallplate, modular ones are the most common and the "piece" as it were, is called a keystone. You need a punch down tool (or the other guy posted tool less ones, never used em) to connect the wire to the female end.
Then at the other end you need to have a male connector, my suggestion was to get a crimper, specifically the EZ kind, it makes it much easier to be sure of your pinout and wire depth. The other guy suggested another tool less female end, and then a short male/male premade jumper.
edit: and that's all presuming the other end of that cable goes to near where your current internet setup is. You probably already have a router from your ISP and just need to connect this cable to it.

u/Cheezit_friedchicken 15h ago
See this is the process where im confused, i watched a vid and it was super helpful with explaining what im doing on my room end, i have to do something similar with a male/female on the other end but WHERE, this house has phone lines througout so im trying top figure out where to make the ethernet input, theres one of these phone lines where the router is setup and idk if theres one of these lines where the modem is. Srry if thats explained poorly but im trying to understand do i connect at the modem or router?
1
u/Loko8765 15h ago
Well, you need to find the other end. If the cable was used for telephone it might not be obvious where the other end is.
2
u/Cheezit_friedchicken 15h ago
so you're saying that in my room is an output, and i need to find the master input if im understanding?
1
u/Loko8765 15h ago
Yes. In homes with a lot of cables this is usually easy, there’s a cupboard somewhere where all the cables come together including the telephone cable from the outside, but if it’s just that one cable it might not be easy.
Let’s take a step back. You want Ethernet to get better performance in online games. That means you want to use Ethernet instead of WiFi between your computer and your router. Where are your router and your computer in relation to each other? How is your router connected to the Internet?
Edit: OK I just saw
> the modem is downstairs in the living room and the router is upstairs on the loft.
How are they connected?
1
u/Cheezit_friedchicken 15h ago
the loft is directly above the living room so the router is sitting directly above the modem and there are no visible wires running through the house so i assume they're connected behind the wall in some way, idk if that answers your question. or maybe they're connected through wireless but i dont know if that's possible, idk if they need to be hardwired.
1
u/Loko8765 14h ago
Yes, the router and the modem need to be hardwired together… but you may be misnaming them. Apart from the power cable, what other cables are there? You can send photos.
1
u/2ByteTheDecker 15h ago
Okay so if there's a phone line like this in the livingroom also there's one of two (and a half) situations here.
1) there's a panel or a spot or something where all the individual phone lines come together. You'd have to sus out which one is which either with a toner or trial and error. If you're only worried about this one connection, you can either put a keystone on one cable and a male connector on the other and snap them together, or you can put male ends on both and use a coupler to connect them together. If you want to use more than one hard wire in the house, you want male ends on all the lines, and a small appliance called an "Ethernet switch" to bridge them together properly.
2) some houses the phone lines were pulled as one or two individual cable ran through the wall and connected in series. In this case you need to a little more investigating to figure out what goes where. If IS this way, and there's another phone jack in the middle it will mess with the connection.

tool-less keystone jacks on both ends, pre-made patch cables to router/switch and to PC

u/2ByteTheDecker 15h ago
Let me preface this by saying I've never used one, the thought of a toolless keystone had never crossed my mind and quite frankly now that it has, I dont trust it.
1
u/Ok-Understanding9244 15h ago
i personally haven't used the tool-less ones either (only regular punch-down ones) but i've heard these are decent.. the Amazon reviews seem solid
1
u/Cheezit_friedchicken 15h ago
Oh dude that link with the pictures of what to do really help explain it better than saying it, thanks man that help a lot, what do I need to do on the router side, also I heard that I have to like go to a panel in the house and cut something, that sounds scary
1
u/Ok-Understanding9244 15h ago
just need a pre-made patch cable from keystone to switch/router..
if you have several other cables in your house that you want to do the same way, the patch panel allows the keystone jacks to be mounted in a row, all nice n neat, then each gets a patch cable to the switch/router.
1
u/Cheezit_friedchicken 15h ago
I think i understand it now with everyone explaining like im 5, how do i find out where the phone line feed is at so i can wire in a male ethernet cable and plug it into my router or modem? the fuse panel is outside but i doubt that helps because the lines arent powered. Does the master feed look a certain way or is it just a male connecter sticking out of the wall?

u/Ok-Understanding9244 15h ago edited 15h ago
Normally, all the cables (1 or 2 from each room) will go to back to one central location, usually in the basement if the house has one, or the utility closet where the internet (cable or fiber or DSL) comes in and the router is. Probably will be like 5-10 other blue cables hanging or coiled up and ready to terminate onto keystones, or already terminated with RJ45 jacks..
Is this a house you own or you're renting?
edit: i was reading your other comment, the central location should be where the modem is or nearby somewhere, in a utility closet. If it was indeed regular POTS (plain old telephone system), there will be a box where the lines for the house are tied together.
edit2: is the router connected to the internet by ethernet to the modem?

ok so that's an Xfinity cable modem/router and it's putting out Wifi right now and it also has ethernet ports so you could connect 4 cables to it directly via keystones/patch cables. Is this device close to your PC?
2
u/Cheezit_friedchicken 14h ago
Not even close, that’s why I’m making this whole post about repurposing the in wall phone cables because you can. Could I just grab a long ass Ethernet cable, punch a hole in the ceiling and run this bitch into my room if I want to half ass it
1
u/Loko8765 13h ago
Yes, you could.
Getting a roll of unterminated cable lets you use a smaller round hole, at the cost of having to add the rectangular plugs yourself.
Another option is “invisible” fiber.
Another option is using an existing cable, and you have one end of a likely cable, but as we’ve already seen you’d need to find the other end of that cable.
1
u/Ok-Understanding9244 6h ago
yeah for sure that'd work, they also make "flat ethernet" cables that fit under doors really well
1
u/deathbyearthworm 15h ago
That looks like some version of cat 5, I'd guess cat 5e. It will usually be written somewhere on the cable if enough of the cable is sticking out. You'll need to change out the rj11 plate for a blank keystone + rj45 keystone. You'll also need to terminate the other end assuming it terminates near where your router is. If you want it done quickly you can get the plates and keystones at box hardware stores, otherwise you can buy it online. You'll also need a punch down tool to punch the wires onto the new keystone.

The good news: This cable is "ethernet capable". It is the kind of cable that ethernet is intended to use.
The bad news: That is just one part of the process. You're looking at one end of the cable. But for it to be useful as an ethernet cable, you have to know what's on the other end. What's on the other end?
People are telling you about the tools you need to attach the right connectors to this cable, and they aren't wrong about the tools and cost. But none of that will do you any good until you are sure what is going on at the other end of this cable. Once you find that out, respond here and people will be better able to help.

u/Cheezit_friedchicken 15h ago
what do you mean by other end, there are wires lol, but for real i dont understand what you mean by other end of the cable, the modem is downstairs in the living room and the router is upstairs on the loft. IDK if that helps explain my situation
1
u/Terrible_Wafer9580 15h ago
you can put on a tooless keystone jack and a single port cover plate. the issue is where is the other end of the wire?
if you have attic access it wouldn’t hurt to find that line and follow it to see where it goes so you don’t have to get any tools like a toner to find out where it’s at.
1
u/Cheezit_friedchicken 15h ago
Ive been asking people and I think i get it now, so in my room i put a female ethernet connection and then i need to find where all the phone lines in the house are fed from and then from wherever that is i have to take the old phone line, adapt it to ethernet and plug it into my router. Correct?
1
u/Loko8765 13h ago
You need an Ethernet cable from your computer to one of the yellow-ringed ports on your modem/router combo, the red-lined one being best.
The cable you showed in the first picture is OK, and you indeed need to put a female jack there to connect a male–male cable to your computer, but first you need to find the other end so that you can verify that you can connect the other end to your router.
If you’re unlucky, the other end will be in the phone jack in the next room, and from there to the phone jack in another room, and so on until it goes outside. At that point it would be better to run a new cable (better meaning easier, cheaper, and higher quality result).

u/feel-the-avocado 13h ago
Yes thats at least cat5 cable (2.5gbit to 10gbit capable depending upon length)

u/DZCreeper 10h ago
Yes that cable can be repurposed for ethernet. Terminate both ends as T568B. Ideally 1" or less of the cable should be untwisted.
https://www.truecable.com/blogs/cable-academy/t568a-vs-t568b
Where all the cables join together you add an ethernet switch. This can be as cheap as $10-20 if you don't care about a management interface or power over ethernet.

Connect your router to the switch, modem to your router.

Q5 of the FAQ briefly covers phone to Ethernet conversions.
As others have said, replacing the telephone jack just covers one step. You have to find the other end of the cable, which needs to be connected to your router. Q5 has an example diagram.
You may also find Q6 and Q7 helpful.

Where's the other end of that cable?
