Hi David,<br>
<br>
One peril of running a (what I think is a) no-longer-supported
version of xubuntu is the possibility that the repositories for the
version are stale. If that's the case, they're not being updated.
So, while a later version might support your wifi chipset, 12.04 may
not. Also, you are probably far behind the kernel update system. <br>
<br>
The file /etc/apt/sources.list controls what drivers are upgraded,
among other tasks. If you type 'sudo apt-get update && sudo
apt-get upgrade && sudo apt-get dist-upgrade', your computer
references sources.list to see which servers it should draw
information from.<br>
<br>
Try this. It's a bit risky and convoluted, but I can help you out
if the computer gets stuck.<br>
<br>
Pre-steps. ----> Go to your terminal. <br>
<br>
-------------------> I like ROXTerm (shameless plug). Type 'sudo
apt-get update && sudo apt-get -y install roxterm' to try
it. <br>
<br>
<br>
<br>
1) copy /etc/apt/sources.list to another file. ie. go to x:x/$
(your root directory) and type 'sudo cp /etc/apt/sources.list
08132015-sources.list' or however you like to organize your backup
files. <br>
<br>
2) get a thumb drive and, while in the root directory, type 'sudo mv
08132015-sources.list /media/x/[drive]' (whatever your thumb drive
name is, check /media/). Unmount the thumb drive and put it
somewhere safe.<br>
<br>
3) Now type 'sudo apt-get update && sudo apt-get -y install
gedit && sudo gedit /etc/apt/sources.list'. This will
install gedit, a basic text editor. Then sources.list will appear.<br>
<br>
4) Hash out all the lines (#). This will tell the computer to
ignore the old commands.<br>
<br>
5) Copy the hashed out parts, put the copy first in the file, and
remove the hashes from this copy. The computer will read this part
of the file.<br>
<br>
6) Where your see 'precise' in the un-hashed out part, delete and
insert 'vivid'. What this does is temporarily upgrade to 15.04.
There's a backup of the old 12.04 sources.list on the thumb drive,
so no worries. <br>
<br>
7) Save sources.list, close gedit, and return to your terminal.<br>
<br>
8) type 'sudo apt-get update && sudo apt-get upgrade
&& sudo apt-get dist-upgrade && sudo reboot'. This
should update/upgrade the system and then reboot it.<br>
<br>
9) See if wifi works when the computer comes back up. <br>
<br>
Good luck. Keep us informed. <br>

</div>
<div>I've since done this and it does show up. I'm using 12.04
because I both like it and it runs better than 14.04 on these
machines, but on the Ubuntu support area there's someone who
had the same problem - also with an Intel 2200 board - on
14.04 and followed the suggestions as far as I could without
success.</div>
<div><br>
</div>
<div>I wish I understood all the various commands, but as yet,
I've not really got my head round them (it takes so much
longer when you are older).</div>
<div><br>
</div>
<div>The update was downloading/installing Google chrome major
update (10s of MB download) when the wifi suddenly failed. As
I say, the wifi board works perfectly under Win XP (indeed I'm
using the actual computer now with the XP HDD in it to write
this).</div>
<div><br>
</div>
<div>I assume that something has corrupted the driver(s) and I
need to reload these.</div>
<div><br>
</div>
<div>When I click on the eternally running attempt to link with
either our (Virgin Superwimp) hub or the repeater, the system
sees it perfectly but can't link with it. It behaves as
though the password is absent.</div>
<div><br>
</div>
<div>Regards</div>
<div><br>
</div>
<div>David</div>
<div><br>
</div>
<div>PS Michelle, I've spent some time getting the machine
loaded and exactly as I want it and I'm reluctant to reload
from scratch, which was my first thought.</div>

Type lspci | less and see if the network card shows up on
the list. Look for a term like "Network Controller" or
similar.<br>

<div>Hi David.<br>
</div>
If you don't have much personal data, or if
you can do a backup I would simply use a new
version of Xubuntu and reinstall everything
formatting the HD.<br>
<br>
</div>
I know that it's quite drastic, but probably
quicker than trying to fix things!<br>

<div dir="ltr">Hi All,
<div><br>
</div>
<div>I was updating my Xubuntu this morning
when it announced that it had failed to
download and stopped. Since then I
haven't been able to reconnect to WiFi.
It continually tries then asks for the
password for the wifi, repeated ad
nauseum.</div>
<div><br>
</div>
<div>Now I have two identical laptops, so,
knowing the other has a perfect,
identical, wifi board, I swapped the HDDs
over, only to discover:</div>
<div><br>
</div>
<div>a) The other machine with the Xubuntu
SSD transplanted now can't connect to
WiFi, although it could when it was
running Win XP</div>
<div><br>
</div>
<div>and</div>
<div><br>
</div>
<div>b) the computer that couldn't connect
under Xubuntu, happily connects when
running Win XP!</div>
<div><br>
</div>
<div>So the problem *has* to lie in the
Xubuntu system. This is my "Notebook" and
I will need it running next Monday and
Tuesday, as I'm on a course then.</div>
<div><br>
</div>
<div>Here's the system details:</div>
<div><br>
</div>
<div>The machine is a Toshiba Satellite Pro
A10 (yes I know it's virtually scrap -
that's why I can use it as my Workbook,
it's not even worth stealing!)</div>
<div>It has been upgraded to a Pentium 4 and
has 1 GB memory and an 80 GB SSD.</div>
<div><br>
</div>
<div>The WiFi Board is an Intel 2200 one.</div>
<div><br>
</div>
<div>The system is running Xubuntu 12.04
(personal taste).</div>
<div><br>
</div>
<div>I'm still a fairly new newbie and would
appreciate fullest explanations of how to
sort this out (please talk down to me!!!)
and how to generate any further
information the list might need to help
me.</div>
<div><br>
</div>
<div>I am wondering if the drivers have been
corrupted and if so, how to remove and
re-install them. The system runs fine on
a wired connection.</div>
<div><br>
</div>
<div>Thanks in anticipation,</div>
<div><br>
