1) Install Wireshark
2) Connect laptop to Wifi network
3) Connect TV to laptop's Ethernet port (and set TV to use wired Ethernet)
4) "Share" your wifi connection with devices on the Ethernet port.
5) Run Wireshark and start a capture session on your [edit: Ethernet] port.
Edit: recommend capturing from Ethernet port as there will be less other traffic.
… or use http://fritz.box/html/capture.html if you have a Fritz!Box router – it's a great device anyway but especially useful for capturing your own LAN and WAN traffic.
WOW! I have a fritz box and never knew it could do that.......... mind blown!
You would need a Ethernet crossover cable for step 3, not the regular cable, correct?
Most ethernet ports auto-detect these days so there isn't really much need for crossover cables any more.
