How to lay a 20m self-retracting LAN cable - tips?

I have already had very good experience with dLan. You just have to try it. If it doesn’t work, you just send the things back.

I have also already had good experiences with it in several places. However, only with the "originals" from Devolo. Two other manufacturers distinguished themselves by frequent reconnections. The speeds were always faster than the respective internet connection would have required and what a WLAN (without purchased access points) could have provided.

Of course, if you have a 400 Mbps connection, it could be tight. Then only the network cable helps. But the average 50 Mbps in Germany should work.

Another question: Why don’t you want to keep the last meters constantly connected? Isn’t your PC fixed on/under a desk? If it’s not a PC but a notebook, I can’t think of any use that wouldn’t be sufficiently supplied via WLAN. (Well, actually, I could think of one... but I don’t believe in it ;-)

Regarding the actual topic: a 20-meter LAN cable is already quite long and not really practical anymore. With self-retraction, the cable would have to have some kind of reel or similar. If so, it would have to be in two parts or is the whole cable supposed to be pulled through the house, or where is the retraction supposed to be located? You can lay the cable and have the open end sticking out, and that’s fine. Or you can use one of the ideas from here in the thread.

One could securely lay the cable itself onto a surface-mounted box and then attach the pull-in device there. Or work with a coupling.

Good day, Thank you for the tips! I have a FritzBox 7590! 5 GHz WiFi is already running at my home. But I prefer a LAN cable on the PC. I am rather thinking of extending the LAN port of the FritzBox, which then slightly sticks out of the strip, so that I simply have a shorter LAN cable in the room. Do you know if the speed will drop because of this? Currently, I have a 100,000 connection, if 70-90 thousand arrive, I would be quite satisfied.

LAN at home == 100Mbit or 1000Mbit. There are no intermediate stages. Either it works or it doesn't. The FB has 1GBit (1000Mbit) LAN ports. If you use norm-compliant CAT5 or CAT6 cable, do not exceed 100m cable length, and the connection elements (plugs, sockets) are correctly installed, you will get 1000Mbit speed between the PC and the Fritzbox.
