I suggest you have a look at the WirelessLeiden and IEEE 802.11 MIBs. Some weeks ago I reviewed these for applicability to FreeBSD. My findings can be found here:- http://people.freebsd.org/~bms/dump/ieee-mib-freebsd-applicability.txt http://people.freebsd.org/~bms/dump/leiden-mib-freebsd-applicability.txt I haven't released my trafd/snmp code yet as it's unfinished. Many of the statistics you mention could be computed within the net80211 framework with some changes, although they sound more suited to the needs of network performance research within an academic context as opposed to the needs of Joe User, which has been my focus at this time. Some further work could be done in the area of presentation. Currently I use Cricket and rrdtool to produce time series graphs with a 4-minute average. Real-time monitoring and visualization tools are highly desirable. BMS
