Asus usb-ac56 dual sma mod

I did a mode for my rx Asus, removing internal antennas,
soldering a bridge inside the test connector and mounting a second sma connector.
Removed the test connector outer housing with a very sharp / thin wire cutter. I had to bridge it because I broke it. If you don’t touch it, it’s already bridged, just leave it as is.
Now RSSI reading on the second sma is the real thing.


omg… After reading this I realized that I cut traces to PCB antennas for no reason. I am using those test connectors to connect antennas. So I thought I need to disconnect those PCBs…
I am trying to use tplink t4u v1 though.

How did you get both antenna rssi to show up? I have done similar connection as you but i only see the main antenna, i dong get any values for the second antenna.

Is there some special setting to activate to get the diversity of the ac56?

There is one AC56 with 2 antennas air side and 2 AC56 ground side. Openhd displays the two RSSI signal from ground, not from the 2 air side antenna. Each wifi stick from ground (and no matter how many antenna has each ground card) will get one RSSI value to show up in osd.

What about TX side? I saw in your settings you are using STBC. As far as I figured out, STBC uses both antennas for transmitting. But in your photos/videos, I see that you only have single maple antenna connected on TX. Shouldn’t second maple antenna on TX improve the signal in case of STBC?

I posted above your question, that I have 2 antennas on air side too (tx).

Hello !!
i am new to open HD and have AC56 also .
Is there need to bridge J2?
I am afraid to remove it with cutter.

Hi. No need to touch that connector, it’s bridged by default. I broke mine, that’s why I had to bridge it.

thanks !

Heavy… but strong. Good for ground side.
