There are some great Wireless traffic filters on wireshark website as well as on WiFi Ninjas Blog Wireshark filters. Wireshark supports limiting the packet capture to packets that match a capture filter. Wlan.fc.type_subtype = 0x04 & wlan_radio.signal_dbm < -75
The filter used in this example is: ip.addr 192.168.0.45. Wlan.fc.type_subtype = 0x05 & wlan_radio.signal_dbm < -75 With the latest releases of Wireshark, you can capture data for the Ethernet, wireless. (wlan.fc.type_subtype=3)&(=55)ĭisplay Filters related Weak signals: wlan_radio.signal_dbm < -67 Wireshark Display Filters related 802.11 k,v,r traffic: 802.11 k,v,r Wireshark Display Filters related Retries: retry Every field in the packet details pane can be used as a filter string, this will result in showing only the packets where this field exists.

It was shared as image file so I decided add different filters together and type here so people can just copy paste the filters instead having to type again themselves. This filters for any packet with 172.16.1.1, as either the source or destination. You can also use the syntax of the form tcp.flags 0x0XX, for example. These display filters are already been shared by clear to send . The same is true for 'tcp.port', 'udp.port', 'eth.addr', and others.
For example, 'ip.addr' matches against both the IP source and destination addresses in the IP header. Some filter fields match against multiple protocol fields.
