Is it possible to have long range Wifi?

My school has around 100mb/s up and down speed, and I was wondering if it were possible to maybe use some piece of equipment to get the signal from miles away? If not that far I would still be able to reach other Wifi signals from further away. I've been told to look into a Wifi repeater, but I'm not sure if that is what I'm looking for. Now that I'm rethinking what I've just typed it sounds stupid, but I guess I could go ahead and ask you guys anyways.  

It sounds like you want something like this.

From the reviews it sounds like it's possible for a few miles if you have line of sight. I've always want to get one and try it out.

Ubiquity makes some stuff that may be able to do what you are looking for, but you're likely going to need line of sight, and you'll need one at each end (one plugged in at your school, and one at your home).  Not to mention that anything that's going to work over that range isn't likely to be cheap.

What Woody posted might work, but I have no experience with that antenna so ymmv.  Again, for that distance, if it works, you're gonna need one at each end.

There are point to point wifi solutions that can reach 5 miles (Has to be line of sight and properly aimed)  ... it depends on how much you want to spend and your needs

Also check youtube and they can show you how to build your own directional antennas out of small satellite dishes.. 

Anything that would work would be enough money to just get your own internet connection in the first place, most likely. There is just no easy way to do it. I would think to run cables or something as wireless over that range would be laggy and unreliable, but wired isn't very feasible either. It would be nice, but I don't think is reasonably possible.

back when I used to steal wifi cuz they weren't protected. I got as far as 500 feet. You need repeaters or a huge satellite dish. I think there's a YT video out still where they stole internet from across the lake. I honestly haven't done this since 2008-2010.

Actually, this is how I am connected to the internet here. We have an anthena pointed to an access point on town building 3-4km away. Its really not the fastest way, but it is a way when you have old or no infrastructure to connect to. You can have anthena working on 2.4ghz, 3,6ghz 5ghz - it all depends how crowded the signal is and what interferences you are dealing with. Both transmitter and reciever has to work on same technology.

 First thing to take into consideration is if the school will allow you to tap into their network. If so ubiquiti's nanobridge M series are amazing and cheap ( i get them for around $80 bucks a pop. I have links around here that are 15km away and get good signal just on old tv antennas of houses.

 They are rated for up to 50km but your signal would be crap if they aren't high enough.

 Great thing is they are a fully boxed solution, coming with all the hardware you need. Just put them together run a network cable and they are fairly easy to setup.

 Now go, and google my friend.
