iMBAPrice - RJ45 Network Cable Tester for Lan Phone RJ45/RJ11/RJ12/CAT5/CAT6/CAT7 UTP Wire Test Tool

Do NOT use a flathead screwdriver, as it could damage the punchdown terminals. Get a cheap punchdown tool and do it right. It may also be worthwhile grabbing a cheap continuity tester, to validate the rework.

You could add plugs at those cuts and then try a cable tester like this, moving the remote part to each jack until you get a signal: https://www.amazon.com/dp/B01M63EMBQ

All the rooms have a coax and phone jack that I replaced with Ethernet ports. IF the Cat5+ cabling has been properly prepped for data/networking, you’d just need to add an Ethernet switch at the central junction to get the physical cables interconnected as an Ethernet segment. example Ethernet switch A cheap continuity tester, >like this<, can be exceedingly helpful for line identification and validation, to make sure that the wires are mapped straight though. (Better testers can offer more functionality, but at greater cost.) One you’ve verified the lines are properly terminated, you should be able to connect >these cables<, I’m guessing, to the network switch to get all the Cat5+ lines interconnected as an Ethernet segment. You’d then just need to get your router’s LAN wired to the switch, either directly or via one of the now interconnected in-room RJ45 jacks. (see >here< for more on reworking Cat5+ for data/networking; see >here< if you find that you still require MoCA for some locations)

The wall jacks not being properly connected was my one fear Nothing to "fear"; it's a common issue and typically an easy fix ... with the right tool. punchdown tool RJ45 continuity tester central Cat5+ termination highlights

Seems like the prior resident may have already been using the Cat5+ cabling for networking, given the old Linksys network switch shown in your photo. (What's its model #?) You may still have some rework to do, but it's possible that you just need to connect the necessary cables to the Linksys switch to enable Ethernet connectivity between rooms ... upgrading the network switch if it's just Fast Ethernet (10/100 Mbps).

As others have said, those blue cables are more than likely CAT5 capable of handling Ethernet. You would want to buy a few things to be able to use them as Ethernet RJ 45 Plugs (Pass Through): RJ45 PlugsCrimping Tool: CrimperWire Strippers: Wire StrippersCable Tester: Cable TesterNetwork Switch: Network Switch You would strip the blue wires back enough to crimp the RJ45 connectors on to them, and then use the cable tester to ensure that all 8 wires crimped correctly and find out where the run goes (which wall jack in the home) Then use the switch to plug all the cables into and you have a network with Ethernet now. The switch I linked is probably overkill because its really meant for an Omada system, but it works well for powering devices over Power Over Ethernet like Wireless Access Points or IP Cameras... I did this at my first condo in 2018. Took me a few days to get the crimps right and figure out where all the lines went, but once I did that oh man it was so nice having wired Ethernet. I did this again in my single family home when I ran the cables myself, that took longer but the result is so worth it.

This was a goal of mine, when we first bought our house. There was no clear path from our basement, where our utilities come in, to our second floor. It wasn’t until years later, when I was replacing our second floor flooring, that I revealed a pass through that allowed for clear passage of wire up to the attic. The main path was running the Ethernet cable through the air return ducts. Running wire through air return ducts isn’t ideal, but you can buy specific rated type of cat6+ cable called “plenum” rated, which has extra insulation for this use case. If you have a clear path room to room, the most challenging part of this DIY might be splicing and crimping your own cable. Bug a good cable crimper. I used this Klein cable crimper, which works great, but it’s still takes patience to get it just right. After you splice and cap each end of the cable, a network tester saves a lot of frustration by ensuring you have a solid connection on both ends.
