I can't seem to get my browser/email to connect to Internet. In terminal I can ping www.google.com to my hearts content but I can't connect to it with Firefox. I have no hair to pull out and I don't want to pull scalp. BTW, Ubuntu gets on just fine, out of the box, but I can't stand Debian Linux.

when you installed, did you enable firewall? if so, check there to start...
can you
$ telnet www.google.com 80
if you get a connect, outbound is ok...

No to the telnet and I disabled the firewall and still had no success. Also IPV6 is disabled.

Has your browser got "File->Work Offline" checked?

Configure NetworkManager to manage your interface. Some Gnome apps ask NM if the net is connected and believe what it says, even if it's not actually managing the interface.

Assuming you have a router and that Ubuntu works fine through the router: from a gnome terminal try: netstat -nr. Make sure the default route (0.0.0.0) is pointing at the correct interface (eg eth0). Check your name servers (cat /etc/resolv.conf). Since you can ping, you should be ok, but sometimes these steps will show you what the problem is. Make sure your browser is not trying to connect through a proxy server.
Minor misconfigurations can cause some interesting problems (such as my Thunderbird issues and I should have known better).
Again, use telnet (as said previously) to make sure your firewall is not blocking outbound ports 80 or 25.
[gaf@rosetta ~]$ telnet www.google.com 80 Trying 72.14.204.99... Connected to www.google.com (72.14.204.99). Escape character is '^]'. ^] telnet> quit Connection closed.

If you can see a Network Connect Icon, put your mouse on it, what does it say ?

I cannot telnet out, 'cat /etc/resolv.conf' yields
nameserver 192.168.1.254 #Generated by NetworkManager domain home search home
and 'netstat -nr' yields

also, the upgrades work too.

I assume 192.068.0.1 should be 192.168.0.1
For 1, your name server is set up to point to your LAN, possibly your router. I would suggest manually adding a valid public name server: For instance: nameserver 8.8.8.8 nameserver 192.168.1.254 #Generated by NetworkManager domain home search home
Then ping some site on the Internet, such as www.blu.org. Then try the telnet exactly like this: telnet www.google.com 80 Then copy the lines and paste it to the email. Additionally, try disabling both selinux and iptables. It is possible that these are blocking outbound port 80.
