I've got a 2 months old Laptop with Kubuntu 22.04 ThinkPad T16 Gen 1 (16" AMD).
uname -a
Linux tp-ThinkPad-T16-Gen-1 5.15.0-60-generic #66-Ubuntu SMP Fri Jan 20 14:29:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Sometimes (several times per day or just 1 - 2 times per week) my WLAN doesn't work anymore. In those cases, I seem to be connected to my network but with 0 up and down traffic. There are usually 5 wireless networks visible in my network widget (close to the clock, bottom right). When the network doesn't work anymore, there is only the connected on.
If I disconnect, there are no visible networks anymore.
A normal reboot takes around 30 sec or so.
A reboot during having this problem here, takes around 3 minutes.
I see hundreds of entries here:
journalctl -rb -1

Network / house details:
- There are two floors, the router is in the room directly below me (about 2m as the crow flies, certainly with reinforced concrete in between).
- The repeater is in the hallway (approx. 4m as the crow flies, only one wall/room door in between)
- Router: FRITZ!Box 7362 SL
- Repeater: FRITZ!WLAN Repeater 1750E
- I use the standard WiFi, guest WiFi is switched off on repeater
- I only connect 2-3 devices (2 laptops, 1 mobile phone) to the router directly from the room via the router
- The remaining devices on the upper floor are connected to the repeater (reason: repeater is near the microwave and when it is on, WiFi no longer works)
When I'm in a longer session and it suddently doesn't work anymore, I see:

Currently, I need to reboot to reactivate my network.
This: sudo service NetworkManager restart
does not help.
Hope someone knows how to fix the problem.
Alternatively: How can I avoid the reboot?
