I have Wi-Fi in my university and it is provided to every student. But I live a little far from my university. I want to receive Wi-Fi signals with this 24dBi Directional Range Booster WiFi Parabolic Grid Antenna. Is it possible to catch wifi from around 2kms. Also the wifi router of university is not in line of sight and one or two buildings come in between.

Is it possible to receive? Thanks for your help!

I think this is a lost cause. If you could set up a chain of repeaters, that might solve the problem, but you'd need people along the route willing to set up repeaters. Even then, repeaters aren't the best idea, each one adds latency and another point of failure that would be out of your control to fix in a timely manner.

Well receiving won't likely be a problem. However transmitting back will be a problem, the power output on your wifi chip and antenna aren't likely powerful enough to be picked up by that antenna. Even if it does pick it up, there is likely to be so much interference from sources closer to the universities antenna, your uplink will just be noise.

Do you have any possible solution to this?

Have you tried to connect to it? Does your laptop even see it's SSID?

That is a huge distance when you consider wifi is meant to run at 100 meters in a house and maybe 300 meters outside. You get nowhere near that because of all the people using wifi and interfering with each other.

You to a point are on the right track but you need a directional antenna on both ends in most cases. The main problem will be that the far end likely will not be able to detect your signal without some large antenna.

Next nobody uses antenna like that anymore. The cable that you use to connect to the end device is expensive for stiff that does not absorb most the extra signal the antenna gets. What is done now days is to combine the antenna and the radio in a single unit. The cost is about the same so nobody uses just antenna anymore. The company linked in the above post sell lots of these solutions.

In addition to all these other problem you must have a clear line of sight, no trees and especially no buildings.

Thanks for your opinion. Can I use TP-LINK TL-WA5210G to solve my problem?

You would need them on both ends on very tall poles to get over the top of the buildings.

Those are extremely old technology. They run only 802.11g which degrade 802.11n connections so lately people disable the ability of their router to even support old stuff like this.

Just checked the displacement distance and it is just 750 meters. What are the possibilities now?

Clear line of sight maybe if you are lucky. A building in the way you have no chance. It takes almost nothing to block wireless signals. We have some kind of energy film on the windows at work. You can see though it but the day they put it on you could no longer even detect the AP outside the building.

I would go outside and stand on your roof. If you can even detect the AP at the college with your PC or phone you might have a chance. If you get nothing then I would not be too optimistic.

not to mention each one halves the bandwidth!
