I am running XP and ubuntu 9.04 on a Dell Inspiron laptop. I have wi-fi access and ubuntu can see and connect with it. However none of the intenet applications (like Firefox) can see the net. What do I have to do to make these applications see and use the connection. The XP side works fine.
The first thing is to make sure that you are really connected to the net. Try pinging Google. Then, just to be sure, you can use "echo -e 'GET / HTTP/1.0\n\n' | ncat www.google.com 80".
If that is working fine, you could try a packet sniffer like Wireshark to see where the information was trying to be sent. It could be a setting in your programs, but as it effects multiple programs I would think it is a system wide setting. Some things to check are your routing table and your firewall settings. It seems strange that you can connect to the internet, but applications can not. You may want to try some different applications, perhaps Lynx, to see if they are effected too.

That's an unusual problem unless you tampered with Firefox's proxy settings. Try checking the proxy settings to see if anything other than the "use no proxy" or whatever is checked.
click edit > options > advanced > network > settings
and you should see the proxy settings from there

Pop a shell and try
If not, say:
There are dozens of things that could be wrong, the results of these should point out the most common problems though.
