Converting RJ11 to RJ45 requires changing the connector type while keeping the wiring intact.
Converting RJ11 to RJ45 requires changing the connector type while keeping the wiring intact.
You're dealing with a slow home Wi-Fi connection caused by several factors: outdated hardware, limited bandwidth from a single RJ11 port, and many devices using the network. You're considering upgrading your physical connection to a standard Ethernet cable to potentially improve speed and reliability. This approach could work if your router supports higher speeds and better performance with wired connections. If you'd like, I can help you explore other options or troubleshoot further.
I’m uncertain about the precise internet package I have, since it wasn’t selected by me and comes from my ISP’s proprietary router. It uses a phone line because my building is quite old, and installing new Ethernet isn’t feasible.
Start by understanding your current setup. Determine the technology they use—ADSL or VDSL—and reach out to them for details. This will help you assess alternative modems and possible configurations, like using a bridge mode with another router, which might enhance local performance without altering your overall internet speed.
I’ll try to find the plan I have. I recall the rated speed was about 100Mb/s, but the speeds I’m seeing don’t match that. It seems it’s likely VDSL. The router is quite old and simple, so I doubt it supports advanced features like bridge mode—it doesn’t even have antennas. I know the cable limits my connection speed, but I still want to make the most of what I have. That’s why I’m considering upgrading to a better router with a RJ11 to RJ45 conversion idea.

The router's output will match the input speed of the cable as long as it meets its specifications. With gigabit Ethernet ports being common, it’s unlikely the issue lies with the router itself—more likely the problem is with your internet service provider's line. Try connecting directly to the router and measure the speed without other devices, then compare it to your plan. A better device won’t help if the connection remains slow.
The network setup predates Ethernet becoming common, so it likely used a traditional phone line. Testing internet speed via cable is tricky since my laptop lacks an Ethernet port and I don’t have another device with one.
Hey there, friend! You’re in the UK, right? In my area, the RJ11 port on your ISP router connects to a type of broadband like DSL or faster ADSL/VDSL from FTTC. Most home phone sockets act as standard BT connectors, while RJ45 ports (Cat5/6) are used for linking computers, gaming consoles, and smart TVs. Does your router have both RJ11 and RJ45 options? Is there a login page you can access—usually something like 192.168.0.1, but often listed on the device itself with credentials? What speeds are you seeing? If you’re on an FTTC line and live close to the cabinet, speeds around 80/20 are typical; anything slower might mean a weaker signal or you’re too far away. You can definitely wire a laptop or PC directly using RJ45 and run a speed test. If you notice much faster wired performance compared to wireless, does your router support both 2.4GHz and 5GHz bands? Try switching one off to see the difference. Also, are all your wireless devices showing similar slowdowns? If you can share some photos of your router, I’d love to help identify the model and ports.
Poland. Testing the actual internet speed is tricky since my laptop lacks an Ethernet port and I don’t have any other devices connected. I managed to access a configuration page that seems dated from around 2015. It lists the connection type as "PTM over DSL (VDSL)/PPPoE" with upstream/downstream rates of 60/6 Mb/s. The speed I see on my laptop is only about 5756 Kbps down and 105 Kbps up, which is far below what I expect. When I run a speed test, I get around 2Mb/s upload and 0.23Mb/s upload. This huge lag seems to come from other devices using the router, not just the router itself. The router only supports 2.4GHz, and it’s fluctuating every few days or weeks unpredictably. Right now it’s so slow that browsing is nearly impossible, and even watching YouTube videos buffers constantly. I’m not sure what’s causing this inconsistency. Sorry if my understanding is off.

I'm not sure how it functions there, but you could contact the ISP explaining the disconnected devices and the mismatch, especially since the equipment is outdated—they might send you a replacement for free.
