WAN Router Tutorial

Hi all - wonder if someone could point me in the right direction.

I work in a computer/commo lab that would like to simulate and test
TCP/IP over RF. Basically - we want to use an RF link for our
transmission medium instead of a T1/Cable/DSL/other...

The RF Link is not a problem, and setting up a LAN is not a problem.
The problem is that none of us is familiar with setting up a WAN
router. We would like to serialize the data from the LAN to pass it
over the RF link and analyze the results.

We currently have all the equipment for the RF link, and I am setting
up a Linux box with an ImageStream WanIC520 card to be the router.

The manufacturer has not been a lot of help, probably because they are
used to dealing with TELCO pros. I am not one.

So - if anyone has a good recommendation on a beginner's tutorial on
WAN technology, I would appreciate it. I apparently am not googling the
right terms.

Thanks for any help!

The $1000 question is: Is there a driver for the card or enough
information to write one?

Yes - there is a driver supplied, and it seems to be working - but we
have not been able to get data into or out of this card, and I am
starting to suspect that it may be how we have our stuff wired...

I built the cable to interface to our equipment, but I think there may
be something I missed. Hence the request for a tutorial or guide on WAN
technologies...

Working - how?

Does it show in 'ifconfig -a'?
Does it have an IP address?

If you tried to ping the local address of the WAN card,
it proves nothing of the card or driver: the Linux IP stack
is smart enough to route ALL local addresses via the loopback
interface, lo, so the ping never visited the driver or card.
