@gian Thank you very much for your explanations, I’ll take a look with my partner because the problem still exists.

It’s not exactly common that you have to manually set a WiFi channel on the router for smartphones/tablets, but in this case it’s worth a try since the problem still exists. The error is probably to be found with Centro Business, since you wrote yourself that your S23 Ultra doesn’t cause any problems in other networks. I am also not aware that the S23 series has or had any general problems with the WiFi.
Apple and Samsung mobile devices are known for allowing the weather radar detection (DFS) to be addressed by the wireless access point, which leads to an immediate WLAN radio channel change including a long-term radio interruption. Manual WLAN radio channel selection in the wireless access point provides a solution. See:

@GrandDixence But I can’t underline that. Why should Apple and Samsung in particular have problems here? Here in particular, almost everyone actually uses an Apple or Samsung cell phone. If many people had problems like this, the forums would be full of them! I have never had to manually change the WiFi channel because the device kept losing the connection. Regardless of whether it is a cheap or expensive smartphone.
@r00t No, I actually don’t know anything like that. Have you set the WiFi channel on your router manually or, in other words, do you also have WiFi interruptions with your device if you have set the channel selection to automatic?
The problem was also discussed by a few people in the Samsung forum, but there have been no new posts for a good 2 months…
What else occurred to me, maybe resetting the network settings would help. Select — Settings — General Management — Reset — Reset Network Settings. You then have to enter the password for your own WLAN again. It’s definitely worth a try.
@Samsi I once told my partner that and he said you couldn’t select the channel at Centro Buisness. I’ll have to take another look with him at the weekend and show him all the posts here again. Thank you very much in advance. Unfortunately, I haven’t found anything new in the Samsung forums yet. In other WiFi (it works on my Eltern). I was hoping for the July update, but unfortunately the problem still exists. I already tried resetting the network around March, but I’ll do it again at the weekend.
I have/had the same problem again and again with the S21 Ultra. Since it didn’t get any better with the new IB in public WiFi or at home and only works with WiFi (5G works without any problems), I tried a cache reset.
This doesn’t help in the long term, but it gives me peace for 2-3 months.
You can do the whole thing like this: https://youtu.be/N_DHV36xAzU
Caution: DO NOT choose Factory Reset!!! This will delete all data.
Wiping the cache partition does not delete permanent data.

@DomiP Thank you very much for your tip. I haven’t dared to do that yet. I got another update a few days ago and I’m curious to see whether the error is still there. After the penultimate update the error was still there, but not as frequently.

Solution found for WiFi problems with Centro Buisness 2.0 and Samsung s23 Ultra and two brand new laptops
Our Zyxel switch used the same IP address on the Centro Buisness 2.0 as it has itself and newer devices apparently can’t handle it afterwards.
Now my partner has assigned its own IP to the switch and the problems have been solved for almost a month now, I hope it stays that way. Otherwise I’ll get in touch later.
