I've installed Ubuntu on this old netbook as it struggled on Win7 (and i'm fed up wrestling the laptop off the kids).
All well and good except I cant get wireless connection. It works fine when wired, and by fiddling with settings I get an icon that tells me i'm connected but I can't access any web pages. The icon is a bit odd though - rather than the radio waves it looks like a little telly with radio waves in it. I've no idea what this means, and can't find by googling.
Am I close to resolving this or on completely the wrong track?
Linux is a bit funny when it comes to wireless drivers.
That aside, are you sure security settings etc are correct?
I think so, I've matched the setup on the laptop as much as i could
If you run a terminal session and run ifconfig it should show you all of you network cards and settings.
Does the wireless adapter show up and does it have an IP address?
Ifconfig says:

Okay so WLAN0 is your wireless link and it has an IP address. The next thing you need to do is establish if you have a default gateway and basic network connectivity so if you run the route command in the terminal it will tell you the default gateway.
Then run a ping to the default gateway address. If that returns okay you have basic network connectivity.
