To be able to use some vpn, i installed the xl2tpd on Ubuntu, but it did not work and i removed it. I changed a bunch of configuration files during the process. I used this tutorial: http://markusthielmann.com/blog/hotspot_shield_ubuntu
My modem configuration is set to bridging mode. So I also used pppoeconf to configure my broadband connections. And after restarting my system I can't see the connections Icon on the top bar. Wireless networks are not recognized and listed.
What can I do to identify and solve the problem?
When I right-click on the connections icon on the top and select "Edit Connections..." in the wireless tab i can see the connection but when I click the connections icon under "Wireless Networks" it says "Device Unmanaged". Previously it listed the available networks there.
The output of
sudo lshw -class network is:
