Ok, so the drivers are up, it is able to resolve names, it could be just a browser configuration problem in Ubuntu. I am not sure if there is a firewall, but maybe you could try disable it temproarily and see if that works.

Also in the browser you are using, perhaps try telling it that it has direct connection to internet.

now i am able to access the internet via firefox.

i am unable to access the internet via any other means.

viz
gaim - not connecting.
bittorrent - not connecting
XchatIRC - not connecting
Evolution mail - not connecting.

any idea how to cure this ?

What was the problem with firefox before (when you were not able to use the ineternet)?

have you tried disabling the firewall or atleast allowing the ports required by those services access to internet?

[arai]

i dont have firewall in linux. i have firewall only for windows.

or atleast allowing the ports required by those services access to internet?

how shud i do this?

[AlexK]

Uh, ubuntu might have a firewall, Since I have only used it briefly, I can't say for sure. Try checking under network settings or system settings.

As for opening the ports, it again depends on which firewall software you have installed on your system, or the system has installed for you.
