I live on the sixth floor of a flat and office is jus 150-200 metres - can see from my balcony but its not direct (there is another flat entrance covering the way) and I need a wireless connection dere

Ive got the Belkin F5d7231 Router (which im not sure if i could take the ariel of and what connection it is) and would like to connect an antenna to improve the range so can pick up the internet connection in the office

Ive got the 5.6ghz Square Grid 27dbit Parabolic antenna - Would i be able to receive a wireless connection in my office



Will this work?

Any Help would be very appreciated

Thank You
