K1 connectors designed for Ethernet networks
K1 connectors designed for Ethernet networks
Hi all, burning question: I am currently using the existing landline phone connections in my home to carry an Ethernet connection from the main office into my room: my current plan is based on my belief that the phone cable is just one giant run of cable that wraps around the entire house, eventually connection to my room from that main office. To do this, I am just putting rj45 wall jacks into the main office and my room. My issue lies here: while taking out an RJ11 jack in my kitchen wall to check the wires, the individual wire (blue + blue/white) broke. I remembered I had some K1 connectors from a networking kit I purchased. I'm unfamiliar with these little guys, as I've never used them. I only know they can be useful for splicing together landline wires in a pinch. Can I use these little connectors to splice those blue/bluewhite pairs back together (blue + blue, bluewhite + bluewhite)? The cable continues its normal twisted pattern after about an inch of being split. Note: the entire line is a cat5e cable. If there is any other better, affordable way of doing this without having to pull the line, please let me know. Let me know if you need any additional information; I'm not in a rush.
Avoid using Scotchloks on Ethernet unless you're comfortable with limited speed. Extend the cable further and rewire it. Don't overload a single Cat5 run, as it can turn into a passive hub. All devices on that line should stay within one collision domain. Success is unlikely if performance improves. As Ethernet speeds rise, crosstalk becomes more problematic. The four pairs transmit balanced signals; continuity isn't sufficient for reliable data transfer, unlike older systems such as POTS or LocalTalk where you could route it through rough terrain.
I understood everything and (with K1) my speed is around 850 Mbps download and 30 Mbps upload. Back then, over Wi-Fi it was 200-300 Mbps download and 15-20 Mbps upload. Either you don’t trust these small devices enough (go K1!!!) or I had a lucky connection that went straight from the office into my room. On every wall port, there’s just a cable with a phone jack built in. I think this lets the signal flow smoothly without disruption. As you said, cables are twisted for a reason, which can reduce interference. I have two ports in my room and an unmanaged switch nearby in case I need to extend the line further. Since I don’t know the full layout, any advice would be great. I’m still learning network setup.
The phone lines start in a phone box outside, and where they end, I have no clue. Like I said, it's just a phat run of Cat5e configured for landline. Since all the cables for the T568A/B are there, I figured it would work for Ethernet. This was a week-long project (including the time it took for everything to come in the mail), so I got disturbingly lucky that it was this easy. And from what I know (do NOT quote me here) , Ethernet cables can be spliced into for another device as long as you use a switch, managed/unmanaged. So: [Modem] │ (Ethernet Cable) │ [Wall Jack - Room A] │ [Cat5e In-Wall Run] │ ┌────────────────────────────┐ │ Room B Wall Plate │ │ ┌────────────────────────┐ │ │ │ Keystone Jack 1 (IN) │<──── From Modem (Room A) │ │ Keystone Jack 2 (OUT) │─────> To Next Room (Room C) │ └────────────────────────┘ │ └────────────────────────────┘ Keystone Jack 1 --> Connection to switch | ----> Device Switch | | ----> Continue the run to a different room Edit: This is all me spitballing. I took a Networking class last year (going into another one tomorrow) and I'm just going off what I remember Edited August 7, 2025 by christian244
