Wireless card, Dual Antenna VS Single with larger dBi

[kazol97]

I recently bought a wireless card (TL-WN8200ND v2) which has two antennas, 5dBi each. I need to be able to receive signal from a router which is located at about 100m away with some obstacles in the path that I cannot avoid. For now I have only been able to connect for a limited time with low speed (at about 500kb/sec). I have to move the antenna very often, disconnect and reconnect, all these in a non practical manner. So I was wondering if it is worth to buy a new antenna which will be 9dBi. From what I've read the two antennas are in order to cover a larger area and they cannot be used to lets say replace a single antenna of higher dBi. Does anyone know if the new antenna will improve the situation, so at least I wont have to move it all the time? Is it worth to try it ?

If you are trying to connect to a WIFI source 100M away, you really need to use a directional WIFI bridge. Like a Engenius or Ubiquiti. The antennas on a WIFI card are not directional. You need all the transmit to be focused toward the WIFI source.

Look at an Engenius ENS202 or a Ubiquiti nanostation

So the wifi bridge will work LIKE a repeater ? I mean I will have to set it up to point to the direction of the router (since it is directional) and then it will CREATE A NEW AP to which I will be able to connect to ?

Also is there any cheaper solution like lets say a directional wifi adapter ?

Keep in mind that although the distance is big, I can still see the access point with the 5dBi antenna, and occasionally I can also connect at low speeds.

Get a repeater or range extender

I know the Engenius will create a local WIFI source (I have one of them), I haven't played with a nanostation. You can alos use a wired connection from either of the units, which if you have a desktop would be a better choice.
