Hey guys, i just wanaa know that whether this router will be able to receive those WiFi signals from at-least {200 metres}, where the actual Wireless modem is kept??

It's Antenna gain is 3dBi.
Reception Sensitivity is as following:
270M: -68dBm@10% PER
130M: -68dBm@10% PER
108M: -68dBm@10% PER
54M: -68dBm@10% PER
11M: -85dBm@8% PER
6M: -88dBm@10% PER
1M: -90dBm@8% PER

I don't know what these values indicates...

You are asking a lot from a general WiFi adapter even without physical obstructions and signal interference. It may not work in the best of conditions, but if you are anywhere but the country, signal interference is almost certain to overwhelm the WiFi connection you want.

If you put it outdoors the signal might travel that far...ie you might be able to detect it. That does not mean you could use it. The critical issue is that there everyone uses wireless and the radio frequencies are jammed full. People are lucky to get this to work at 10 meters sometimes because of all the other people interfering with them.

The actual answer to the antenna gain question is very complex and partially depends the mode the router is transmitting in. You are best to think of this as 2 independent 3db gain signals they do not add to increase the signal level. Do not assume putting larger antenna on makes much difference the problem is not the signal strength it is the interference.

There is no way anyone can answer this question with assurance that it will work. It is very situational dependent. Things like being in a city or in the remote countryside matter significantly. Your best bet is to buy an adapter from a place that has a good return policy and experiment to see what the results are.
