[SlugLUG] Campus wireless problem: gateway in wrong network

[Peter Belew]

Hi Mark - thanks!

I did in fact report this, in an addition to my email about  Ticket 21906,
which was originally about not getting responses from authentication
servers a couple of times this quarter. (It's possible that may have
been due to the subnet problem, but I think I tried from XP as well
as Linux that time too).

Anyhow, I think this will account for what I was observing on the top
floor of McHenry a few months ago, too. It's interesting that Windows
seems to be ignoring the subnet mask!

I appreciate your tracking this down!

Peter
