How to find MAC Address of Default Gateway ?


This is my first question here. I am on a LAN and I need to find the MAC Address for my default gateway. Googling out said that I have to use packet capture to do this, so I want to use Wireshark. Thanks.

No need to use Wireshark, even though you could. It is usually much easier just to use a couple of system commands to find that one out.

E.g. on Windows, run "ipconfig /all" on a command line to see the IP address of your gateway. Then ping that IP. Finally, run "arp -a" and find the gateway IP. Next to it you'll see the MAC address.

If you want to do it with Wireshark, ping the gateway and capture the ICMP packets. Look at the ethernet layer for the echo request destination MAC.
