WLAN disconnect automatically

Hi all

I’ve a very big problem.
My new Jetson Nano Ubuntu server is disconnecting automatically from the wifi.
I’m able to find the following at /etc/log/syslog (this repeats about 300 times in the log):

Hi schmuckimarco89,

Not sure if this is still an issue, please try with the latest JetPack 4.4 DP to see if issue still present.
