Wireshark crashes after ZEPv3 plugin installation. Which Wireshark version should I use ?

There are following 3 branches of Wireshark distribution:

– 1.12.x current stable release

– 1.10.x previous stable release

– 1.8.x old stable release

You may use arbitrary branch of Wireshark if you are satisfied with capabilities of native ZEP dissector.

If you want to use our ZEPv3 plugin which brings additional info such as precise timestamp, channel and band info you need to use the Wireshark 1.10.x or higher. You can find more info among Wireshark branches and their compatibility here: .
