After sudo apt-get update last week and restart I lost WiFi, tried to fix through Ethernet:
Code:
sudo apt-get update
sudo apt-get remove bcmwl-kernel-source
sudo apt-get install bcmwl-kernel-sources
sudo apt-get install --reinstall linux-headers-generic
Did not had WiFi when I first installed Xubuntu 16.04 2-years ago, then all I needed was bcmwl-kernel-sources. Now I also lost Ethernet as well, I can see the home network, but it keeps connecting forever, but never connects.
So currently my Xubuntu 16.04 has no internet connection. On dual-boot Windows Ethernet and WiFi works perfectly. I removed bcmwl-kernel-sources and manually built from dpkg with needed dependencies. As other dependencies version were (2.23-0ubuntu10) I used same.
I read these, but could not fix myself:

https://askubuntu.com/questions/5586...reless-drivers
https://ubuntuforums.org/showthread.php?t=2214110
Code:
bcmwl-kernel-source_6.30.223.141+bdcom-0ubuntu2_amd64.deb
libc6-dev_2.23-0ubuntu10_amd64.deb
libc6_2.23-0ubuntu10_amd64.deb
linux-headers-generic_4.4.0.130.136_amd64.deb
This neither helped. I am a Linux rookie and using Ubuntu is always ongoing use, learn and study project for me. So a fix and hopefully an explanation what is wrong and why would be helpful.
Would appreciate both fixes- WiFi and Ethernet. Will post useful information that should provide the current state of my machine.
