Can I convert phone jacks to ethernet?

By Liam14 ·
I wish to move a PC into my bedroom, with the goal of utilizing ethernet to increase speeds. I believe the ports around my room to be phone jacks. One is labeled to be CAT 5, while the other is unlabeled. Is this possible for me to do as a budget-friendly DIY project? Thanks for any and all help, I really need it.

You need to...

....look at the outlet closely. An Ethernet connection looks very similar to a telephone line but is slightly larger to accommodate the extra wiring required. If both plugs are identical, you will either need to rewire the connection (add a Ethernet cable in the existing plug) or install a new Ethernet cable with a new connection/receptacle.

You can't just retrofit an existing telephone line that only has 4 wires with Ethernet that uses 8 wires.

The one labeled cat 5

might be an ethernet connection or can be wired for ethernet. Where is the other end of that cat 5?

The one with the CAT 5 label is a good find.

Remember this question has many priors such as
https://www.google.com/search?&q=Can+I+use+phone+jacks+for+Ethernet

And while there are offers such as https://www.amazon.com/Phone-Jack-Ethernet-Adapter/s?k=Phone+Jack+to+Ethernet+Adapter we can't expect operation at Ethernet speeds (10 megabit and up) on POT (plain old telephone) lines.

Given the primary goal my nod is to Powerline kits. Here's a few examples:
https://www.amazon.com/NETGEAR-PowerLINE-1000-802-11ac-Gigabit/dp/B01929V7ZG/ will give you the Ethernet and WiFi in that location.

Ethernet only is a little cheaper: See the top 10 at https://www.amazon.com/gp/bestsellers/pc/1194444/ref=pd_zg_hrsr_pc

What is the hardware setup where the machine is now that allows you to get on the internet?
