When I first time tried install my TV to my notebook it found LGtv and i put PIN code but connection was not established, since that time i could not find LG TV via my notebook. I upgraded all drivers in notebook and got new soft for LG TV but still notebook doesn't see LGTV. So i start thinking, thinking once again thinking and eureka ;D. When i first put Pin code LGTV installed on notebook as new projector like Belkin Screencast doing. but becouse of LG's software old version it couldn't wark well and notebook had not seen LG but it still was install in a system. So go to control panel i found in Devices and Printers option my LGTV. I removed it from notebook and tried once again establish link between notebook and LG. Notebook found once again LG, i put PIN code and connection wan established and run without any probles since that time.
But new software is required in TV and notebook (drivers of Intel video card and wifi card)
Sorry for my english ;P
