I'm sorry for my english.
I just checked my emails and then noticed a weird symbol that I've never seen before. It was near the Wi-Fi icon. I clicked on it and it was written that it is an icon for "Location Services" and that they are off. I went to Settings, found there "location services" and there it was written, they were "in use". When I noticed that web pages were not loading, I turned off and on the Wi-Fi and found no Wi-Fi network. Then I restart the laptop, the sign for "location services" disappeared and they were now turned off in the settings and WLAN said that no wireless adapter was found.
I tried not to find the wifi adapter in Ubuntu 18.04 and could not get the wifi adapter working – clean 19.04 installation – network unclaimed
I do not know what else to post, that can help ….
