Old Phone Jack for ethernet

Moved some old furniture in my room to make room my new desk. Found this old phone jack that was hiding behind it. My parent's house is about 35-38 years old, just for reference. I was wondering if I can just straight connect an ethernet cable to the plug to my computer. Or do I need other peripherals? The main router and modem of the internet is downstairs with my dad's computer, if that information needs to be relevent.

Ethernet and phone jacks is not the same the phone jack is smaller 

Reminder⚠️

I'm just speaking from experience so what I say may not work 100%

Please try searching up the answer before you post here but I am always glad to help

No. Not only would the ethernet plug not even fit, but that phone line probably only has two conductors in it (maybe four) so even if you somehow managed to fit the ethernet cable in there and have the pins on the connector line up with the contacts in the plug...it still wouldn't work.

well thats a pohone plug, not a ethernet plug, so a computer can't connect directly.

 

Depending on how your house is wired there are some dsl solutions for a locak network that may work here for getting wired networking to your pc.

Take the faceplate off and look at the cabling behind it. Does it have any kind of writing on it? You want to look for Cat5. 

Fine you want the PSU tier list? Have the PSU tier list: https://linustechtips.com/main/topic/1116640-psu-tier-list-40-rev-103/

Normal Ethernet needs 8 cables/conductors, if you have those in the cable just replacing the plug might be enough. ;)

When i ask for more specs, don't expect me to know the answer!

100mbps ethernet only needs 4 wires, 8 is for POE or Gigabit

Would you consider 100mbit 'normal' ethernet in todays world? :D

But you are 100% correct! (didnt want to confuse the situation even more.)

yea that looks wired for phone.

 

THis is proably your best you can get https://www.amazon.com/Tupavco-Ethernet-Extender-Kit-Repeater-VDSL/dp/B01BOD8C9W/ref=sr_1_2?dchild=1&keywords=ethernet+over+dsl&qid=1601403175&sr=8-2

 

You probably need to change wiring at the central panel aswell.

 

Wifi or powerline might be better options to look into.

Most people just want internet they don't even know or care that they have a small LAN at home. 100mbps is OK for things like adsl

I appreciate the help guys. I'm just looking for way to get a faster internet connection so I can download huge video game files. I have wifi but since I found this I thought it would be worth a shot to check what my options are.

Well there are options to make wifi work a bit better as well.
Changing channels on the router to something thats less used.
Better antenna placement. And if its only point to point maybe an antenna reflector.
Goodluck! :)

what speeds do you get over wifi? Upgrading your wifi might be the best option.

As someone who used powerline, if you're going this route be warned that your connection will go down often, especially in that old of a house. Have wifi as a backup, and regular Ethernet wiring is always preferable to powerline.

 

My powerline went down so often that i just decided to switch rooms lol. When it works, it works great, but when it doesn't it really sucks

For wifi thats really not bad.
(would depend on your internet ofcourse but still, nice numbers)

 

If range isnt much of an issue maybe upgrading to 5Ghz wifi might be an option, its less used so reception can be better but speeds are way higher and pings are usualy lower. (but its easier to drop connection when range becomes an issue)

Phone uses RJ11 connector, while ethernet uses RJ45.

You could use the conductor on the wall to pass new cable and change the faceplate to RJ45.
