Sorry if I was unclear somewhere along the way, but I'm not connecting
through my mobile phone.

I'm talking about using a wireless LAN card. Specifically, this one:
http://www.logitec.co.jp/products/wlan/lanwgcb.html

Since I last posted on the topic, the situation has got a little worse.
When I boot up, I get a Gnome error. Basically, there's a grey box on
the screen and it takes a looooong time to complete the login process.
Then I get an error, which is described in detail here:
https://answers.launchpad.net/ubuntu/+question/4499

The short story is that the reason I'm getting this error, so far as I
can understand it, is because there is an error in my drivers that is
holding up some component of Gnome. Since the WLAN card is the only
thing I've messed with, I'm assuming that there is some error in the
driver installation that is the root of this problem.

This error came up after I read on the net somewhere that using
"apt-get" to remove a package called "network-manager" would solve the
problems I reported earlier.

Briefly, after I uninstalled "network-manager", the activity light on my
WLAN card was very active, indicating it was working. However, at that
time I was not in a wireless network zone, so I couldn't properly test it.

When I went to a wireless network zone, I had to shut down my laptop for
the journey. When I rebooted, the Gnome error became apparent, and the
WLAN card was no longer working.

Since then, uninstalling and reinstalling the drivers, and uninstalling
and reinstalling "network-manager" does not seem to have any effect.

So, the current situation is that the WLAN card driver is installed with
some error, causing a Gnome error, and not connecting to any netowrk.
Further, when I try to go to "System->Administration->Network" in Gnome,
the it opens a blank window in which there are no buttons or options at
all. Probably another symptom of the same Gnome problem.

Here are some commands and output that hopefully provide some insight.
If there are other commands I should report the output from, please let
me know.
