Use Ethernet over telephone lines for connectivity
Use Ethernet over telephone lines for connectivity
The cable in the photo begins at one telephone socket and ends at another in a different room. It’s a copper telephone cable, not an UTP type, and its diameter is bigger than standard UTP wires. I understand Ethernet Cat 5 uses four wires, so I attempted to connect my router via this socket using a Cat 5 cable, hoping it would give the PC in the other room an Ethernet connection. However, the signal doesn’t seem to work properly. Is there any possibility to use this existing cable for Ethernet in that setup? Since it’s built into the floor without a conduit, replacing it with UTP isn’t feasible.
That's fascinating. I had no idea it was possible. Appreciate the reply! It also sparked the thought of using an Ethernet-to-USB adapter. Would be cool to test it out.
I wasn't referring to connecting it into the main DSL, since only one router is allowed. I was talking about Ethernet to VDSL adapters, which are quite uncommon and costly. In most cases, WiFi or Powerline would be more suitable, though Powerline might interfere with your DSL if that's how you're getting broadband.
I also wasn't aiming for the exact goal you described. I think I'm following what you're trying to achieve. My plan is to use the existing Cat3 cable for a LAN connection between rooms without digging through walls—a situation that's not feasible here. Right now, I don’t have RJ45 connectors ready to attach, but I’m sure I’ll give it a shot once I get them. I’ve already physically separated the rooms you want to link from your ISP connection. You don’t need to set up your own DSL for the LAN. I’m confident this is possible, even at 10 Mbps, which suits me well. EDIT: Yes, it should work. EDIT2: It looks like it might function even faster at 100 Mbps.
In my case, it looks like your cables aren't ideal for Ethernet transmission. The signal didn't make it through. I hope it works for you!
I’m unsure whether that cable is twisted pair—it seems unlikely—and why it doesn’t connect properly. Even if it did, you’d likely be restricted to 10-BASE-T. You might attempt to set it to half-duplex via the network adapter in Device Manager, which could trigger CAT3 mode. However, your switch or router might reject it. The Gigabit NIC on my laptop indicates curiosity, as it appears capable of half-duplex operation for 100Mbit over voice-grade cabling.
