Wifi connection problem after changing from MATE version 16.04 to 18.04.05

Hi, I have wifi connection problems after updating the system from MATE 16.4 to 18.04.05.

Chromium and firefox browsers and the software updater do not establish a connection to the internet.

But I have connection and can navigate with telegram and TOR. Curious.

Do you have any suggestions? Thank you very much :slight_smile:

I had something similar on my previous laptop with Ubuntu.
Try to change IPv6 settings for your connection from Automatic to Ignore or Disabled.DeepinScreenshot_select-area_20201207175436

Thanks!, I checked and change IPV6 settings, but doesn 't work. I'm changing other wifi confs, but without success till now.

Always this message. Thks again :slight_smile:
