All was working well with my dell insp 1501 laptop using Ubuntu 8.10 amd64 and Ndiswapper for about 3 wks and now I cannot access internet any longer. It appears that I am connected to WAP I can see packets are going in / out yet have no internet access through browser or update/insatller. Not sure what may have changed.

Any suggestions would be appreciated.
Im extremely new to linux so plz try to bear with me.

thank you
