Wireshark is a service that allows you to monitor and see what people are using your wireless network for, if you have public wifi. This is primarily used by businesses to ensure that their customers are not downloading illegal items.
WireShark is a great tool for analyzing networks, finding bottlenecks, or for analyzing attacks.
Alone, Wireshark is not a significant threat. provided that no hubs are used on a network and switches are not attacked (see Macoff) then a user running wireshark will only see traffic from their own host (see micro-segmentation). Wireshark and other packet sniffing programs should only be used by administration staff on networks as traditional users have no legitimate use for them.
Wireshark is a perfectly legal network troubleshooting tool. However it is possible to use it in illegal ways, like many other tools.

Down load and install Wireshark network packet sniffer onto a windows machine. Connect the PC to the same switch that serves the AP. Boot the PC, start Wireshark. Set Wireshark to promiscuous mode and select the NIC device you are using on the PC to connect to the switch from the dropdown menu in Wireshark. Write down the mac address of the AP (tag on unit) Start up the AP and watch for DHCP broadcast request from the AP MAC address. You'll see the comment "who has IP address?" XXX.XXX.XXX.XXX? Then a response with the MAC addy XXXXXXXXXX has XXX.XXX.XXX.XXX the IP address tied to the AP MAC is the IP addy you seek.

Fire WireShark, select the Network Adapter you want to scan and it gets to work. By default, WS will scan all data going out or coming in through that adapter. If you want some specific ones, you can always apply a filter.
sequence number is 0 in ethereal but 1 in wiresark :) thank u
