Hi Neil,

NetworkManager should be running in the notification area. I'm
assuming you click and selected your network? If you right-click the
notification icon, and click properties/info, does it show DHCP with
your IP, gateway IP, DNS server etc?

You may want to check the network settings
(System->Administration->Network), to make sure that it's set to auto
(=managed by NetworkManager).

and keyring-manager, it Just Worked for me after I typed in a master

For the manual approach... check ifconfig wlan0, see if it's got an
IP. Also check route -n to see if a default gateway is set up. Can you
ping your router?
