I have a L35-S2171 running XP Home, purchased in December, 2006.
When I use the Software Upgrades link on my Start Menu, after
refreshing it always says there are no upgrades available. And when
I go to the Toshiba website and then Downloads (or Technical
Support), I don't even find my computer model listed.

But when I go into Ask IRIS, and search for downloads relating to my
model number, there's a whole list of drivers and other updates. In
particular, there are a dozen or more released on or about 8/29/06
which don't appear to have been installed in my machine. I don't
know why 8/29/06 drivers wouldn't have been included in a computer
sold in December, but apparently they weren't. Of particular
interest to me right now is an updated Atheros wireless driver since
I'm having problems in that area.

So I'm confused. Why doesn't the Software Upgrades link show these
drivers as being avaiable? How do I know which ones I should
download and install? Is the whole Upgrade thing broken at Toshiba?
