Would dis work? HELPPPPPPPPPP

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

1.The antenna on the Belkin does not unscrew but is soldered to the internal cct.bd.
2.It operates at 2.4GHz not 5.6GHz so the "parabolic" would probably be inefficient.
3.If you don't have Line of Sight between the 2 locations it probably won't work.
Attenuation caused by 18in concrete wall is 18dB
Attenuation caused by 27in external concrete wall is 53dB

Which belkin ROuter would work the best then? From which i can unscrew the ariel?

I do have line of sight - The signal can reflect through mirrors cant it?
