Signal is excelent through 2 concrete walls (-51 on android phone) and also higher than an standard RB951Ui-2HnD with 2-5dbi. With standard tplink 841 signal was very poor and loose conectivity very often.
This is just a testing projects, maybe someone needs this infos.

I assume a solder job ? Good job , looks pretty solid.

Nice

Solder pigtails, and also a thin piece of steel plate on the antenna side. Also I'm proud to see that wireless sped is 98mbps on an online speedtest.

see us photo from inside thanks

see us photo from inside thanks

+1

I have a rb751U-2hnd and I want add a external antenna for more gain.

Can't do. Ruter is already sold.

InoX, please show me photos of the inside boards (antenna connection)

Hi, can you make a little manual where to solder connectors on the pcb?

Can you post some more pictures and manual ?

+1 for some photos. I would like to do this to one i have to get a little extra range

Can't do. Ruter is already sold.

Why you can't it's easy to do?

I think this use that part for solder or install for two external antennas left and right. I will try to do it for my RB951Ui-2HnD. Then I post new subject for my test to know how to do that.

This model is completely different .. but this model RB951Ui-2HnD works I try it.

that is nice !

i have mine working like this over year without issue .

best result if is distance between two MIMO antennas are about 12.5cm

wavelength is about 12.5cm for 2.4 GHz.

you can remove Integrated antennas (there is no need to be 4 antennas)

especially if you put all in the metal box on the roof.

Internal is disabled )
use capacitor

Hi guys,
I also did the mod on my recent RB951Ui-2HnD,

Took the pigtails from a dead TP-Link 941nd and soldered them on the unpopulated (ufl?) connector pads, and moved the small (pain the arse) capacitor on the right track at the Y circuit trace.

I'm currently testing it with 2x10 dbi antennas from Qoltec but I don't see very much improvements, not as my other RB951G-2HnD wich is insane in terms of signal strenght and range compared with the default integrated 2.5 dbi ones. I'll try other antennas I have lying at my lab.

Any tips for what wifi settings would help?

Here are some pics (I know, it looks savage, but I don't care about the looks)

Hi.

Yesterday, i did the mod in two rb951ui, using pigtail u.fl to rp-sma. It was necessary to remove both internal antennas to get the real value of signal.
I compared it with another router and signal is the same through three walls and 16 meters from the Access points (d-link dap-2310 and RB951ui-2hnd with ROS 6.37.3).
Has a print screen from my phone that demonstrate how was the signal strength.
The pigtails have a length of 11cm each.

Here is some prints from mod and App Wifi Analyzer: https://imgur.com/a/GMNP2
