Internet in the house - Best solution?

The internet also comes through a cable from the wall and then goes to the access point ... Advantages? Which ones? Besides being invisible? Poe is also available with surface-mounted access points

APs are available for 20 euros, plus the empty conduit and the data sockets. I wouldn't rely solely on WLAN in the house, but that's just my humble opinion.

Wow, thank you very much for the really helpful tips. I really didn't expect something to come so quickly. Thank you

You need a structured network cabling system, preferably with a central point in the connection room/technical room and connection sockets everywhere there are stationary participants (WLAN access point, TV, desktop computer, network printer, heat pump, ventilation system, ...)

You can operate WLAN simultaneously as a convenience or retrofit it later.

I have 30 network connections distributed throughout the house. Mostly double sockets.

The electrician's price per socket ranges between €80 and €150.
I did it myself.

Actually don't want any radiation at night!

Then you only have the option to cut the power to the entire house and preferably also to the houses and power lines in the vicinity ;).

It’s not that simple to just "turn it off quickly". If the APs are equipped as PoE variants, the power supplier must be turned off - that will probably be the switch. That means unplugging cables or completely turning it off in the evening, but then everything including the phone is dead (if you already have a switch, you can hang your phone on any network socket).

Normally, the times when the access point should be active can be set.
