[Cialug] looking for help with wi-fi

Thu Nov 4 10:22:40 CDT 2010

Looks like I hit the 'send' button when I meant to press 'Enter'.  I noticed
that your earlier snippet included a Realtek device of some kind, but it
looked more like an ethernet controller rather than a wireless controller,
unless that's what the driver was setting it up as, as most wireless devices
tend to use wlan0, ath0, ra0, wifi0 or something similar to denote that they
would have some sort of wireless binding to them that the iwconfig command
would show.  Therefore, I was not sure if the Realtek was the wireless
device to which you were referring or not.
