I've just installed Ubuntu 6.10 and I'm trying to get the internet up

installed the windoes drivers using ndiswrapper and everything seems
to be working fine. I can login to the router at http://10.1.1.1 and
see my linux box as a connected DHCP client through firefox and I can
even successfully ping addresses like www.google.com.

I'm assuming that you mean you can ping google.com from your linux
box (as opposed to from the router).

However, when I try to navigate firefox to any web address, i get no
action. I just sits there for ages before eventually timing out.

If you can ping google, then you do have basic connectivity. A
data packet can get from your box to the Internet and a reply can
come back.

Perhaps the place to look to see what happens to HTTP packets is
your firewall configuration.

Here is the output from "sudo iwconfig wlan0"
wlan0 IEEE 802.11g ESSID:"Jane_Is_Great"

That looks fine. You have an 802.11g (54Mb/s) connection, and with
a signal level of -71 dBm you've got maybe a 10 dB fade margin to
work with.

and here is the output from "sudo ifconfig wlan0"
wlan0 Link encap:Ethernet HWaddr 00:0F:B5:85:A0:61

That looks fine too. No errors showing, but you'd only run a few
packets of data at that point, so it probably doesn't mean much
other than it basically does work.

Any ideas why everything exceopt actually using a browser to see the
internet seems to be working??

When you /ping/ another node the data is sent using ICMP (control)
packets. You might also try using /traceroute/, which sends UDP
(datagram) packets, just to see if there is a different result.
That would be another indication that your firewall is getting
in the way.
