Im looking at the specifications for your 9300 and Im a bit surprised it
runs ubuntu at all. However, glad to see it works on that old of a
machine. I just did a job for a company where we took about 50 older
laptops and put a wireless adapter in one slot and a ethernet adapter in
the other slot. This way they had access to parts of the building that
do not have wireless. You can get a linksys ethernet adapter for less
than $50.
