I am in France having trouble connecting to a particular wifi device.
Called a Freebox.  My wireless adapter can connect to other wireless
devices except the one in this flat (which I connect to with a
cable). I can connect with Windows7 (wife insists on using).  So
there is nothing wrong with the device, I should say.

~$ iwconfig

wlan0     802.11bg  ESSID:"Bouygues Telecom Wi-Fi"
Nickname:"rtl8191SEVA2" Mode:Managed  Frequency=2.412 GHz  Access
Point: 02:1F:9F:BB:80:CA Bit Rate=36 Mb/s

I am connected here to Bouygues telecom but I can not access the
internet.

I suppose you use the network manager applet which Ubuntu uses by
default. Some people have more luck using wicd instead of network
manager. If you install wicd, please remove the network manager packages
because they may be in conflict if both try to use the wireless
interface. But before you try wicd, what is the output of these
commands?

route -n
cat /etc/resolv.conf

That should at least clarify if you got the needed network configuration
via DHCP. The route -n command should give you the IP address of the
access point. You should be able to ping that address. If that works,
you can test the name resolution with

ping www.google.com

Another option would be to reset the access point (disconnect the power)
but I'm not so sure it would help.

When I search for Additional Drivers I do not show proprietary
drivers in use.  I thought Realtek would show up on the list.  I
would reinstall if I could.

As you can connect to other access points, it is unlikely that the
driver is the problem.

Nils, here are the outputs. I also doubt the driver is the problem.
Other networks on the list give me login window on the browser so I am
connecting to those routers.

I can connect fine by cable.

Thanks for your help
