FAQ
Wi-Fi adapters are not recognized after reconnection of the Thunderbolt™ 3 connection:
• Disconnect, wait for approx. 2 minutes and then reestablish the connection.
The adapters are still not recognized despite waiting before reconnecting:
• Disconnect and restart the system (reboot).
How can packet drops be prevented (at high bandwidths)?
• To prevent packet drops, the standard “interface kernel buffer” of 2MB should be increased
to 30MB. A snap length of < 300 bytes is also recommended to also avoid losing any packets
with high-speed networks according to IEEE 802.11ac or IEEE 802.11n. Reducing the snap length
also reduces the stored information in each frame. The relevant radiotap header is still included
with a snap length of 100 bytes. Details of a packet, such as the actual packet contents, are then
not saved.
• For long-term recording, the long-term capture function is strongly recommended.
How can the filling up of storage media be prevented?
• The filling up of storage media due to an ever-increasing file size can be prevented by a so-called
“ring buffer”. This can be set in Wireshark under the tab “Capture/Options/Output”. Check the
checkbox for “Use ring buffer with” and select the number of files.
Does the WaveXpert have an assigned transfer direction?
• For best possible recording of Wi-Fi communication, it is recommended to align the cover surface
of the WaveXpert in the direction of the sender.
