Still wont work most likely. We need to know what driver your machine is
using. Once we know that, we can make sure it detected the card properly
and see what we need to do to get your stuff running. We are almost there,
plus you are learning a lot:) The stuff we are doing here will help you
troubleshoot all kinds of hardware stuff, like scanners not working etc.
As a side note make sure you are broadcasting your ESSID on your router.
Not doing it really isn't that much of a security help, anyone sniffing in
the area can find it out in a few packets anyway.
Ok, when you get home do the following to make sure you have everything set
In a terminal:
sudo apt-get remove wpasupplicant
sudo apt-get autoremove
then do
lshw | less
This will give you driver info etc.
find your card in there, and post the info here...
you should be able to search on wlan0 (once in less, type /wlan0 and hit
[Enter])
my server (wired ethernet) looks like this:
