Share high-speed internet between my condo and a common area building

[Lukamo]

Hello.
I've tried searching the threads but nothing really seems to correspond to my situation ( or if it did, it was terms i could not understand clearly )

I live in a condo complex. In my condo, I have 50mb high speed internet. I have a normal ISP router for 2.4ghz and i got my own router (WD mynet 900) for 5ghz.

In our complex, we have a separate building which includes a gym and a sort of.. common.. rentable "suite" (not sure how to call it) where theres a kitchen, TV, big table, and panoramic windows on 2 sides (see link for the crappiest sketch youll ever see).

My goal, is to LAN in there with friends, as it gets a little too crowded in my condo.

They have internet in that building, but you cant use it for personal use, and you cant use much bandwidth..

I have to find a way to transfer MY internet to that building so that we can all connect to it and have a very good connection.

Now, as the picture shows, theres a couple of factors to weigh in.
I live on the 4th floor, facing directly that building. That building is about 2 stories high. I have a patio facing it also, so when i go out on it, i can see the top of the common building.
Problem is, the actual room, is on the OTHER side of said building (so no line of sight with the windows of that "suite")
I can't permanently install stuff, has to be easily removable and cannot leave any alterations to the building.
Both buildings are about 100ft apart.

So, with all that said, i need a way, wether wireless or wired, to beam/share internet with that "suite" when i want.
I've thought of passing an ethernet cable from my condo to that building when i want to lan, but neighbours will absolutely not allow that as they whine about EVERYTHING (although i can understand how a 100ft cable passing between buildings mid-air might annoy someone)

I've seen something like this http://www.amazon.ca/TL-ANT2424B-Directional-Parabolic-connector-resistant/dp/B003CFATOW/ref=sr_1_1?ie=UTF8&qid=1453041343&sr=8-1&keywords=parabolic+antenna
But i am somewhat a noob in the area of networking, so i have NO IDEA what connectors it takes, how to do the connections, how to catch the signal from the other end (would i need 2?).
I am NOT closed to having to buy a high end router/repeater/AP if it can easily solve the problem.

Can anyone here help me ?

The simplest thing would be an ethernet cable to the patio on your unit with one of these -- http://www.newegg.com/Product/Product.aspx?Item=N82E16833168155 pointed at the common building. You would build a mount that hangs on the railing of your patio. I have no idea how well it will work, but it is probably your best shot.

Wouldn't 2.4 suffer from a significant speed loss?
And from the suite, how would I go about redistributing the Internet via a Ethernet hub?
Would I connect a second one of these to receive the signal?

 

[kanewolf]

Why would 2.4 suffer? From the congested RF environment? Quite possibly. I guess I assumed you wanted to be able to use devices directly. If you really want' to setup a point to point network and then bring an ethernet cable inside to a WIFI access point then Engenius makes the same device in a 5Ghz model == http://www.newegg.com/Product/Product.aspx?Item=N82E16833168151 You would put one on your balcony, and one outside somewhere at the clubhouse pointing to your balcony. Run ethernet cable inside the clubhouse to a conventional 2.4Ghz access point.

Okay. So let me get this straight...
My wired modem connects to a engenius on my balcony with a Ethernet cable.
Beam it down to the clubhouse
Receive signal with a engenius at the clubhouse
Connect engenius to my current router (that I would put inside the clubhouse) via Ethernet cable,
Redistribute via wired or wireless connection to the computers inside the clubhouse.

Is that it?

 

[kanewolf]

You probably could do that. I was thinking ... Current router -> engenius <===> engenius -> WIFI access point (or second router). I don't know that putting it on the WAN side of a router won't work but that is normally not what is done.
