Wifi problems x1c

I have the x1c for about one month and one or two weeks ago the WiFi started to get extremely spotty.
Sometimes I get good connections for a few min and then no connection at all.
I have a wlan connection with only 2.4ghz only for the printer and it is limited to one access point.
All other clients on that access point have no trouble connecting (even further away from it).

I get hundreds of these messages from the management console of my net:

Bambu Lab X1C connected to “WIFI”
on “Access Point”
. Connection Info: Ch 6 (2.4 GHz, 20 MHz), -64 dBm, 192.168.xxx.

Sometimes it reconnects twice a minute sometimes only every 2-5 minutes.

It has become so bad that sometimes I loose connections in the middle of sending a new print.

The network and setup (physical place of the printer) has not changed.

What are my options here?
