Does anyone have any useful OIDs for the Linksys WAP54? I'm especially interesting in Client connections or authenticated clients or something to that effect...

Good luck. Linksys uses a limited subset of SNMP to do configuration and setup. All that SNMP does is set some values and return a few results. No ANS.1, no vendor specific OID's, therefore, no MIB. If you walk the MIB tree, you'll see some of the ID information, followed by some glop that can be identified as settable values. I tried to reverse engineer a WAP11 and found a long binary OID that was all the status information on one line. I decoded some of it and suspect I could figure out the rest. However, I was looking for things like number of associations, signal strength, S/N ratio, and other useful stuff. They apparently weren't there, so I gave up. I also found that if I polled this OID repeatedly, the AP would eventually hang. If I find my notes, I'll pass it on.
Incidentally, the D-Link DWL-900AP+ has a similar SNMP misfeature with no MIB available.
Good luck.

I figured that was going to be the answer :(

Yep. What you probably want is an access point that supports the ieee802dot11 private MIB. None of the cheap AP's do that because of the processing horsepower required to grind the full ANS.1 tree plus the wireless/bridge private add-ons. Methinks the cheapest of the bunch that does real SNMP is the Netgear WG302:
If all you want is traffic analysis, that can be done at the router. If you want MAC layer stuff (retrans, connections, RSSI, S/N, etc) it has to be done in the access point (radio). There are scripts that invoke the web page configurations, extract the numbers, and return them in a form suitable for plotting. If the AP has a telnet interface, it's even easier to extract values.

Jeff: Contact me for a copy of the DWL-900AP+ MIB which covers the ..iso.org.dod.internet.private.enterprises branch, including the ..dlk80211bPlusDot11 (sic) branch which implements IEEE 802.11d Annex D.
Hope this helps
