You won't be able to get a normal wireless router to do this, as it would breach the law. There are transmission power limits for standard wireless devices due to their nature of being for local area networks.
You will have to look at professional point to point wireless systems to do this (if you are just wishing to provide network access to a another building) or have to install a managed wireless network to cover a building of that size. Probably in the region of 30 or so access points.
Answer:
You have one hell of a big house or office.
Answer:
No chance, without either a whacking great transmitter and an aerial, or a series of repeaters.
Edit for Tracy, below: how do you propse a mesh network helping here? The network topology has nothing whatsoever to do with this, unless you assume there are other computers within that 900m. If two nodes are 900m apart, you still have the thorny problem of bridging that gap - which, without serious equipment (and in the case of your example, two handy mountains) is quite clearly not feasible.
The best medium for the job is copper cable (cheap and fast, does not require LoS, makes a perfect backbone), or fibreoptic.
Answer:
Don't think you'll ever find a router which will work over that kind of distance, even Ethernet cabling is limited to 150m IIRC. You would need to put in repeater stations every 100m or so.
You could build a seriously high powered antenna and see if that works instead - do a search for Wifi Sniper Rifle to see what I mean

Answer:
You will be lucky. lol Are you trying to share your friends connection or let them share? You will not get 900mtr on wireless, dude it is nearly 1km are you mad?
You can look into this, the spec is at the bottom of the page when you open it, but it still falls short.

pssstt heres a magic trick …….the maxium length is of most wireless is 950 meters ..thas about 300ft…. now some are also adjustable id prefer linksys…easy to setup and use ..
Answer:
900 m? u need antennas for sure…. now depends what u want to do… connect 2 places, or cover area….. to connect 2 places directional antenna for coverage omnidirectional. U cant have more than 19-21 DB transmitting power, after that u are illegal….
Answer:
The real answer here is what is between you and the intended receiver? Wifi is basically line of sight. If you can see it, it will work type of thing. 900m is not a big deal unless you are inside a building and the receiver is outside or there are lots of walls etc.
Links for WIFI have been established at 237miles (yes miles-

)
There are several high powered routers with external antenna connectors which allow you to "customize" your installation.
see some of them at
http://echotechwireless.com and http://defactowireless.com
you can also find information at
http://tranzeo.com and http://motorola.canopywireless.com/solut…
all designed for really wide area coverage.
None of these type units will be at your local stores, it just is designed for "professional" wifi market and stores simply do not carry that. If I were to say you need a pro to set this up, I would be giving you the best advice possible. This needs an experienced hand to help get you the right gear and the right equipment. Check with some.
And if you need "non-line of sight" check on "mesh" networks!
There are companies that set these up and can cover all the area for you with very little effort using just exactly the gear needed.

Answer:
you wont get converage for general wi-fi clients over that range with a single access point.
long range point to point wi-fi links are possible using custom antennas. for example here is the website of someone who achived 10 miles using a pair of old sattalite dishes. Note that this may be illegal depending on what country you are in.
