Today I've installed Ubuntu 15.10 and I can't using internet with wireless connection. In connection information is written that I'm connected, but I can't do anything. When I'm connected with cable everything is well. I tried to connect my WiFi dongle, which I'm using in raspberry pi and everything is working aswell. Here is my ifconfig with WiFi dongle:

You should set your country code and the script results would indicate you are in Poland

sudo iw reg set PL

Then we will change the crda file gksudo gedit /etc/default/crda

The last line of the file needs to be

REGDOMAIN=PL

Save file and exit gedit. Then use Network Manager connection settings and set the IPv6 to ignore for your connection and in IPv4 settings add DNS of 8.8.8.8 and save. Reboot and see if you can have any connectivity
