[Cialug] looking for help with wi-fi

[Scott Prader]

Hi Chris,

Beware of 10.10, it is new, and thus it has many issues.  10.04 is still the
LTS (Long Term Supported) version of Ubuntu and you may find it easier to
find a solution with it.

Is your wifi card builtin?  If so, does it show up under the list that the
lspci command provides?
