To begin capturing packets with Wireshark: Select one or more of networks, go to the menu bar, then select Capture. The 802.11 hardware on the network adapter filters all packets received, and delivers to the host 1. all Unicastpackets that are being sent to one of the addresses for that adapter, i.e. A broken horizontal line signifies that a packet is not part of the conversation. There are other ways to initiate packet capturing. Tcp scan will scan for TCP port like port 22, 21, 23, 445 etc and ensure for listening port (open) through 3-way handshake connection between the source and destination port.
