Here’s a cool DIY on how to convert your home phone lines into an ethernet network. I’ve tried this before with some success but here’s a great how to you can follow.
This is a guide to hacking the wiring of your home. Changing it from a phone line based system to a flexible and extensible home network. I upgraded the wiring in my condo since we didn’t use a analog phone service. I changed all my phone ports to network ports. This allows me to easily transition back to a phone system in the event we decide to use a local phone service instead of cell phones. Now that all of my phone jacks are network jacks I can add a gigabit hub for fast network access. When I don’t need to transfer large files, 2gb and bellow, I can use my wireless network.
Thanks Coarch for the tip!
