Query as per title.

I would of course need to connect the PC to the Smart TV (either via a LAN cable (impractical) or wirelessly (I'd need a wireless USB adapter first to plus into the TV - will almost any wireless USB adapter work? I see that Samsung sell their own)).

I'm also wondering if I could plug a router directly into the LAN port on the TV and then connect to the TV wirelessly via the router (the manual only indicates that a router can be plugged in (via a cable) to gain access to the Internet (via a cable to your phone line) ). Surely though if a router is plugged into the TV it should be possible for the PC to access the TV wirelessly via the router?

Thanks
