Another thought, guessing you are using Ethernet to connect. Do you have Indicator Applet Complete on a panel. If so click on network icon and see if a wireless connection is also shown (would show with more bars and most likely would not have a lock icon like mine) and also if enable Wi-Fi is checked. Blurred out one is my WiFi connected to Internet.
Another question are you dual booting and able to boot XP or did you wipe it?
ok, post the output of lspci, it should show 2 network adapters.
Here is the output of lspci:

I wiped XP
I am using Ethernet to connect.
The Applet looks different to the one you show. It has the Ethernet connection but no wi fi. If I go to edit connections it shows the WiFi connection I set up.
this is your wifi, I cannot find a suitable driver for it.
I suggest buy a $5 usb wifi adapter, plug it in to a usb port and hopefully you can have wifi.
Thanks for your help. Will do.
