Hello everyone!

This is my first thread here in the forum, hope this question can help me and help others seeking a solution for a similar problem.

I currently live in a student accommodation with less than 200 meters from my university however i cant connect to the university wifi from home cause the signal is too weak.

I checked on the software Wifiinfoview the signal quality is around 6 out of scale of 100.
Im currently using an Asus T100 netbook.

I wonder if i buy a long range adapter of wi-fi it would enable me to access my university's network from home?

I spend 50 dollars monthly just to get a limited internet and i am really short in money, so it would be great to use the university's good internet and save money in it.


I was thinking about buying this one :

Here are two pictures one of the google maps with the distance measured and another one a picture from my patio so it gives a good idea (there is a lake in between but not buildings or trees).

If it is possible, what long range wi-fi adapter would you recommend to me ?
Sorry for the long post and thank you so much for reading through it!

That is old crap that used to be one of the better adapters. It is now junk because it is goes not support 802.11n.

Your best bet is to use a device that is designed for this application. You want a outdoor directional bridge. Something like a engenius ENH202 but the exact model will depends on if you want to use 2.4g or 5g.

Now this will entirely depend how much signal can get out of the building on the far end. Since you can at least detect the signal with the built in card you have a pretty good chance. Now you can get pretty big antenna like ubiquti AG-HP-2G20. The advantage of outdoor bridge is these run on ethernet cable and you can mount them far away from your pc if you really need to.

Thanks for the advice, i will try this one as well and see if it works. It seems pretty small besides the info says that is 6x more powerful than traditional ones

Your solution seems pretty good, but is it possible to do a bridge without access to the wifi configuration ?

As i am a student i only have access to a wifi connection with a user authentication which is my uni login. Also, if i get the outside bridge i would be able to use my pc inside of my house with this stuff outside with no wires ?

Regarding 2.4g and 5g i am not sure how to check it?

Thanks a lot for your help!

It is kinda scary that you ask how to check if it is 2.4g or 5g. These are rather complex devices and are not hard to configure but you do need basic knowledge of wireless. If you are only using 1 PC and you attach it via ethernet then it will be really simple. To connect multiple pcs and share a single login will depend how your uni id works but it is generally possible. To connect via wireless inside you will need another device called a AP. This can be any simple router. You would plug that into the ethernet cable coming from the outdoor bridge and place in the house at a good location. You have in effect made a repeater. Still I would get the bridge on ethernet working before you attempt to add the AP.

The frequency and channel being used is very obvious in the scanning tool you used.
