WOULD I NEED TO CONNECT SOME GIZMO TOM Y LAPTOP--AN HP G7 PAVILLION 1070US NOTEBOOOK TO THEN TRANSMIT TO THE BRIDGE OR IS THERE A SMART WIFI BRIDGE MODEL I CAN USE THAT WILL PULL NET ACCESS OUT OF THE SKY AND BRING IT INTO MY SHARP LED HDTV VIA THE ETHERNET CABLE AND IF SO, WHICH MODEL IS BEST, HOW TO SET IT UP AND WHAT DO I NEED TO DO?
