Hi! I am moving to wireshark for use in sniffing wireless 802.11
beacons. My team used to use Wildpackets OminPeek. However, I am
having an issue. Wireshark averages 166305 beacons/hr in my
location, channel 6, while OmniPeek averaged 293149 beacon/hr, same
location, same channel, same card.
Same operating system? Probably not, as:
OmniPeek is Windows-only;
Wireshark uses WinPcap on Windows to capture packets, and WinPcap
uses NDIS to see packets;
Windows prior to Vista doesn't support supplying management packets
such as beacons to NDIS, and Vista supports it but WinPcap doesn't
support that mechanism;
so you're probably not running Wireshark on Windows to capture beacons
(you'd get 0 beacons/hr on Windows unless you're using an AirPcap
adapter, and OmniPeek doesn't support AirPcap adapters, as far as I
know).
What version of what OS are you running Wireshark on?
