wireless – Update to Ubuntu 19 and now the wifi does not stop disconnecting

I have a 2 surface book with Jakeday core that I have signed.
I have updated Ubuntu 19 the other day and now the wifi is disconnecting, it is always said that the ssid but the icon is with a "?" instead of the signal strength, to make it reconnect again, I have to turn off and turn on the wifi.

Here is the output of the lshv -class network:
