Hello James and all,
This is what you want.... if the AP supports SNMP (e.g. ORiNOCO,
Cisco, Linksys, etc.), you can use MRTG (open-source) to capture stats about
your AP. I have done this on a Win2k box and a RG-1000. Not too
difficult.... and I'm not a programming type person, more network admin.
SNMP = Simple Network Management Protocol
MRTG = http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
Good luck,
-Ben
