Hi,
Thanks. I've always heard countless rumors about WPA being wise :) I'll
take your advice and take a step up in technology. My "stubborn
conservatism" probably roots back to the time when not all devices could do
WPA, or at least I had crazy trouble getting things to work. But this
learned attitude was probably around 2000, which was like a million years
ago with dinosaurs and stuff. Time for me to finally get with it.
I found the lagg documenation in docs
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-aggregation.html
Duh! I went through wireless section in the handbook several times, I don't
know how i missed this paragraph in 32.3.6:
"We will cover link aggregation and failover in Section
32.6<http://www.freebsd.org/doc/handbook/network-aggregation.html>
where
an example for using both wired and wireless connection is also
provided at Example
32-3<http://www.freebsd.org/doc/handbook/network-aggregation.html#NETWORKING-LAGG-WIRED-AND-WIRELESS>
."
Thanks again,
Waitman
