If you have "laptop with wireless internet connection", you have a wireless router built into your modem, if there is no separate router. What model is your Modem, and how many outlets does it have?
You have a Bell Sympatico "2-wire" wireless modem/router Best is item 1 plus a 50' ($15) or 100' ($25) cable. Use one of the three ethernet outlets on your modem.
If you do not like to run a cable from your Modem for esthetic reasons, use powerline adaptors (Item 3).
Item 2 will also work fine. There may be an occasional signal drop problem which will not be there if you go the powerline route.
In my opinion, direct cable is excellent, powerline adaptors are very good and wireless bridge is good.
The Netgear WGPS606 Wireless Bridge has an additional advantage of connecting other items to the network - basically for you it will increase your connectivity to the existing 4 plus four more. But do you need them?
Pizza already has 118.7 LNB. He is focusing on questions relating to details of networking which I have already addressed. He seems to have focused on kbox and I do not dispute that.
