How to identify in TL- MR 100 4g router Antenna are working or not ?
How to identify both antenna/ antenna port are working or not ?
In my router, Near Dc jack right side antenna port, when i attach single stock antenna, it's show all signal.
But, when i attach single stock antenna left side, not showing Internet LED, or not any signal.
But when i attach both antenna its shows all Signal.
I purchase this router in June 28, 2021.

I would have thought that you would get a signal on both 4G Antenna ports, the SMA Antenna sockets are the Main (ANT 1) & the other is the AUX (ANT 2), maybe it faulty, I dont know, maybe its not MIMO and that's why & you need 2 antennas connected, & that's what happens when you are only connected to the Main Antenna socket (ANT 1), i am still learning about these modems myself, if anyone else has any insight that would be good.
What you could do it open it up & see (this Voids the Warranty) if maybe 1 of the wires has come off the 4G LTE Modem (Grey wires), here is what is inside an MR6400 for reference, hope this helps.
Edited: Confirmed by TP-Link, it will not work with ONLY 1 Antenna connected to the AUX Antenna in. (NO Signal)

Hi, I see your another post consulting the Main (Ant 1) & Aux (Ant 2) 4G Antenna SMA sockets.
For MR100, the one next to the power DC port is the main antenna port which also explained the issue of @Santosh7.-_Safi
For the MR600, I am checking with the senior engineers, and please wait for a moment.
Thank you very much.

What abt solution of my problem ?

Hi, the antennas are not broken and you might need to keep the main antenna(next to the DC port) properly installed.

Hi all,
Looks like you can use 1 external Antenna (Not MIMO though), it must be connected to the Main (ANT 1) Antenna in socket, & you still must have the standard Antenna supplied connected to the other AUX Antenna in socket as well.
P.S. looks like having only 1 Antenna connected to the AUX Antenna in, just does not work, can someone please confirm this is the case or not.
EDITED: Confirmed by TP-Link, it will not work with ONLY 1 Antenna connected to the AUX Antenna in socket. (No Signal)

Very helpful info. I've been struggling to understand why there is 42kohms at the main aerial port and an open circuit at the auxiliary. I swapped small aerials around and found that as mentioned, only the main aerial port activates the modem and all lights show. I guess the question would be, what does the aux aerial do, why does it not show a 42kohms circuit, how does it handle carrier aggregation? I can't achieve more than 10Mbps in a 5G area, even with a quality directional external antenna. my mobile gets 50Mbps.
