The other tidbit of information to this problem is that I just restarted
my computer and then the print job completed and I was able to log into
the wireless router and display the printer properties page.
It seems like Linux loses the ability to connect directly to the local
network.

Hi linuxguy123!
When it is messing up, from a terminal run #/sbin/ifconfig, and then
#/sbin/iwconfig. Pay attention to the IP settings in the ifconfig
output, and the link quality and specifics of the iwconfig message.
I have two suspicions. 1. The RF path or quality of the wifi modem
(or both) make the actual RF connection unreliable - or - 2. As with
one of the machines I work with the MAC address for the wifi somehow
got the actual MAC of the ethernet connection. If it is #1 change
and improve the RF path (move them closer, see if a differant channel
works better, use an extender). If #2 pull out the pcmcia card (or
turn off the wifi) from the Linux laptop, and then turn it on again -
which consistantly clears it for me.
Regardless, have fun!
