Are LAN sockets still up-to-date? WLAN/wireless is the future!

That's how it looks. Depending on the model, it is also possible to "test" increase the transmission power beyond the allowed level, but even that often brings almost nothing due to the immense attenuation of reinforced concrete/glass/...

Otherwise, I am still looking for an access point that can radiate around the corner, but unfortunately, such a thing does not exist. ;)

I really have to wonder what you all have against houses. I currently have a TP Link Deco M3 mesh system in my house and excellent reception everywhere, even my lawn mower has reception at its base (20m straight line from the nearest Deco). But as some have already said, devices that have a LAN port should definitely be connected via LAN. In our development area, the 2.4GHz WiFi is quite heavily occupied on all channels.

It's more about 5GHz coverage. The ranges are significantly shorter there or get blocked more quickly. We have (including outside) 17 APs. Various ones from Unifi. With our construction style, not even the 2.4 GHz signal reaches the next room :p

Ok, I should test 5GHz sometime. But the decos definitely communicate with each other via 5GHz and that works. One Deco is on the ground floor in the study and the second one is on the first floor on the other side of the house. Luckily, it works for me anyway. 17APs? Intense. How big is the house and what is built into the walls that causes so much loss?

A lot of reinforced concrete and somewhat larger than average.

One should always keep the structural conditions in mind when it comes to WLAN. Often you hear, I only have drywall. But almost no one knows that these consist of gypsum boards and that the boards contain a lot of bound water. Water and WLAN are not the best of friends, though. This was just an example alongside reinforced concrete.

What is also often forgotten is the client. You can install very powerful APs, but if the client can’t manage to communicate back to the access point, it won’t work.

Anyone who wants WLAN in the garden should plan an outdoor access point from the beginning. It should, of course, be protected against direct access.
