[olug] Network appliance for a small business

[T. J. Brumfield]

A friend's restaurant wants to offer wifi and yet keep their internet
connection safe and secure. I haven't had to look into rolling your own
network appliance recently and was curious if anyone on OLUG had
recommendations.

I'm somewhat familiar with pfsense, ipcop and untangle. What is the easiest
and best these days? Are there any distros specifically aimed at wifi
networks for businesses?
