Hello,

here is the situation: we have an "L" shape house and router is in the farest corner. Therefor in some rooms there is signal strong enough, but in the rest of the house, there in none. We have TL-WR843ND router ([HTML]http://www.tp-link.com/en/products/details/?categoryid=1246&model=TL-WR843ND[/HTML]). And I figured out, that a solution for my problem is to buy an antenna to extend signal. First question: Am I right with that one? Iam thinking about this antenna: TL-ANT2409A ([HTML]http://www.tp-link.com/en/products/details/?categoryid=2474&model=TL-ANT2409A#over[/HTML]). The antenna would be connected to that router and I would be receiving wifi via netbook. Second question is: I need only one antenna connected to the router, right? Or another one connected to the netbook?
Between antenna and netbook would be 13 metres of air and another 2 metres of brick wall. Is the antenna sufficient? Will be the signal good and stable?

Or is there any other solution to my problem? (more effective solution?)


Thank you very much for advises.
