|The PBC button is only for use when you have a Linksys adapter - it won't work on the Samsung one.|
When you insert the adapter into the TV do you get a message popping up on the screen? It should ask whether you want to configure the adapter to join your network & following the prompts gets you set up. If you are getting no messages then there's something wrong with the hardware.
Incidentally, the adapter won't give you full internet access - it's meant for streaming media from other PCs on the network (which it does with mixed results) and for updating the (fairly useless) widgets. I don't believe the internet@tv function is available on the 6300.
