Wireless conection with usb adapter but no network access

I've just installed a linksys wireless usb adapter I had laying around to my new pc (windows 7) Under the heading of Wireless connection status everything looks good except the IPv6 Connectivity says no network access. I'm stumped

As no-one else has picked this up I'll try. As far as I know you should disable IP v.6 as it is not widely supported.
