Q3 Which security mechanism is configured for SSID 'LazyArtists'? Your options are: OPEN, WPA-PSK, WPA2-PSK. The Radio Information section is provided in all the wireless packets therefore you are supposed to filter only the SSID of the access point.
This information is linked with frequency and physical medium, therefore you can find it in the Radio Information section. If the access point sends beacons in a specific channel, only stations configured in that channel will be aware of the access point's existence. Q2 The SSID 'Home_Network' is operating on which channel?Ĭhannels are used to divide the WiFi band into multiple sections to share the same band without causing any interference. Here is the combined filter I have used in the Wireshark wlan.fc.type = 0x0 & wlan.fc.type_subtype = 0x8 & = 0 To display only open networks, you can use = 0 filter. This information is carried in the Fixed Parameters Set of each beacon frame. If the WiFI access point is OPEN and no encryption or authentication is enabled, it will have privacy bit in the capabilities flag unset. To display all the beacon frames, you can use wlan.fc.type = 0x0 & wlan.fc.type_subtype = 0x8 filter. The type of management frame type is 0x0 and subtype of the beacon frame is 0x8, in the wireshark you can use the wlan.fc.type_subtype filter variable for this. This is a subtype management frame which contains the information about the WiFi and instructions to establish connection with it.
Your WiFi access point broadcasts the beacon frame in the air medium after a specific interval of time which can be configured in the settings page as well.
Q1 What is the name of the Open (No Security) SSID present in the packet dump? The labs are using pretty older version of the Wireshark, logical operators combinations of the filters may vary, but the field names are hardly changed.
