Converting RJ11 to RJ45 requires changing the connector type while keeping the wiring intact.

You're worried about extra delay when connecting a USB dongle, but it shouldn't affect your mouse or keyboard performance.
Based on your current pricing, you might be saving costs. Most home ISP cellular plans also bundle the modem/router together. The Polish rates aren’t clear, but in the US you can find Starlink Residential Lite for $80 per month (250mbps). There’s a data limit, but it’s unlikely you’ll exceed it. Recently, you can rent a satellite dish or router from Starlink without paying upfront; previously you had to buy it outright, with no hidden monthly fees, which often proves more economical over time. The main issue with Starlink is setting up the satellite dish and running the wiring. With cellular, as long as your provider offers strong coverage inside your home, you can place the device anywhere and it should function properly. For a modern router, remember that none support RJ11 ports—you’ll need a separate DSL modem or a combined modem/router package. As @Kilrah mentioned, verify with your ISP whether BYOD is permitted and what connection standards they require to ensure compatibility.
There are a few issues to note. Viewing images of the equipment would have been useful. You’re using a modem unit that connects to the ISP via an RJ11 port and provides internet through either a standard RJ45 port or an integrated wireless access point. Depending on the model, it might include a built-in switch with several RJ45 ports at the rear. The connection speed listed is 60 Mbps upstream / 6 Mbps downstream. The ISP’s documentation specifies "PTM over DSL (VDSL)/PPPoE" and indicates speeds of 60/6 Mb/s. Your actual performance shows a very low upload of about 2Mb/s and an even lower upload speed. The built-in router offers wireless connectivity with potential speeds ranging from 54 to 150 Mbps, depending on the standard used.
Common standards include:
- 802.11b (Wi-Fi 1): ~11 Mbps max, only 2.4 GHz
- 802.11g (Wi-Fi 3): ~54 Mbps max, same frequency band
- 802.11n (Wi-Fi 4): Dual-band, up to 600 Mbps in theory
For your laptop to connect properly, it must support the same standard as the router. If the router only supports 802.11g but your laptop can handle 802.11n, the link will be limited to 54 Mbps. Conversely, if your device is slow on the network, you might request an updated modem with better capabilities.
Obstacles like physical distance or interference can reduce speeds. Using a USB Ethernet adapter (1 Gbps) works well, and a USB hub can help if needed. If possible, consider switching from DSL to fiber or another faster service. In your area, UPC is now part of Vodafone; you may want to check for newer options.
It seems you're dealing with a DSL connection. DSL has distance limitations—your speed drops the farther you are from the central office. For instance, I can't get DSL in my area. But where DSL is available, speeds reach up to 18 Mbps. There are several ways to improve performance. First, check if your current device can switch to bridge or IP pass-through mode, effectively turning it into a modem and then connecting the desired router. Second, you can disable the WiFi in that box and use a wireless AP; some routers can become APs. Overall, you can enhance slow internet speeds. In the US, many providers like AT&T and Verizon are focusing on copper networks, which often result in poor DSL performance. They’re also rolling out fiber and cellular options. I agree with @mariushm—consider exploring alternative providers. Coaxial, cellular, or satellite services (like Starlink) might work better for you.
