Deco X50-5G - Getting worse signal with external antennas
Deco X50-5G - Getting worse signal with external antennas
Hi. I think I might me missing something as regards adding external antennas to my X50-5G as I get much worse and unstable signal when I add them.
I have tried two types of antennas.
One is the nedis 5g/4g/3g Outdoor antenna. The other is a pair of Teltonika 5G mobile Antennas. Please see the attached photos.
Are these antennas not compatible?
Also, you see that X50-5G has two "RP-SMA Female" sockets. All the 5G antennas have "SMA Male" sockets. So the only way to connect a 5G antenna to the X50-5G is to get an adaptor (SMA Female on one side and RP-SMA Male on the other side). I managed to find such an adapter (please see the attached photo).
Question:
Why did Tp Link do this? Why they put RP-SMA Female sockets? Why didn't they put SMA FEMALE sockets on the router for connecting 5G antennas which come with SMA MALE sockets? (so there would be no need to use an adapter).
Am I missing something? The antennas that come with RP-SMA MALE sockets (and connect to the X50-5G without the need of an adapter) are for wifi, not for 5G/Lte.
In any case, even if I use the adapter and I connect the external antennas, my signal is worse.
Is this a software or a hardware problem? Unless I am doing something wrong or using wrong antennas.
Your kind assistance will be appreciated.

So I just received and tried the poynting XPOL 2x2 5g V3 antenna.
Indeed there is a big difference in signal streangth.
Just for reference, my SNR before connecting the antenna was about 11db-13db and after connecting the antenna and pointing it to the nearest tower the SNR jumpded to 24db-26db.
So I understand that the x50-5g works better with well known and expensive antennas.
I will mark this post as solution. Many thanks for your help.

Hello,
I use the X50-5G V1 with the same firmware and an external antenna. I use the Poynting XPOL 2 V3 5G antenna and was able to achieve significantly better reception with it. The prerequisite for this is that the antenna is correctly aligned and the X50-5G is switched to external antenna. I also cannot understand why TP-Link has installed RP-SMA sockets, but at least the appropriate adapters are included in the package. And I do not have the feeling that the RP-SMA - SMA adapters supplied with the X50-5G have any influence on reception in my case.
best regards

@delong91 Thank you for your reply.
First of all, no adapters came with my Deco box! Please see the photo showing the included items! (I only got an ethernet cable).
Secondly I will try to get the same antenna as you did, since you tried it and it works.
But now, I am mainly concerned that maybe the adapters I got are not correct, and this is why the antennas I have don't work.
Can you please show me a photo of the contents of your Deco included items? Can you also show me a photo of the adapters that came with your deco? Are they the same as the ones I purchased or are they different?
@David-TP Can you please explain why I did not get adapters with my Deco X50-5G?

OK, you're right, that's strange. Neither the packaging nor the data sheet say that the adapters are included. In my case, they were in a small bag with the network cable and the quick installation guide. I've just watched several unboxing videos and these adapters weren't included anywhere. Maybe I got a returned product from Amazon, but it was wrapped in foil like original.
Please note that the Poynting XPOL 2 V3 antenna is a directional antenna and must be aimed directly at the cell tower.
Maybe it would help if you took screenshots of your reception values with the internal antenna and with the external antenna connected. What is the download and upload speed in each case? How far is the cell tower from you? Do you have a direct view of it? For example, you can try app like "CellMapper" to find out where the cell phone towers are nearby and which frequencies your provider uses. If the area is poorly served, even the best antenna will not bring any improvement, because the laws of physics cannot be tricked.

Thanks for your reply.
So ok at least the adapters I got are the same as yours.
Imagine that without external antennas the x50-5g connects automatically to N78 bands. The signal is low but it still connects and I have the best speeds.
So I bought the external antennas to strengthen the signal, and as soon as I connect them and enable them, the X50-5g cannot connect to N78 and reverts to n1 or n28 and the signal SNR fluctuates.
It is like the internal antennas are stronger and can pickup the low n78 signal, whilst the big external ones can't. Or it's like the external ones are not connected...
As soon as I revert to the internal ones, I get N78 and the signal is much more stable.

I don't want to cell lock because the pci of N78 changes during the day(s). I sometimes get connected to n78 with pci 406 and others with pci 73.
If I cell lock, some times per day I lose 5G signal completely.
So I just want to lock the band to n78.
The internal antenna handles this just fine.
The external antennas (even if supposedly are stronger) they lose the signal of n78...

Fyi, I ordered the same antenna (Poynting XPOL 2 V3). As soon as I get it I will run some tests and let you know.
Again, many thanks for your help.

@madvinegar I experienced the same issue with the Bluespot antenna, which is similar to the Poynting antenna. It seems like a software problem where it can’t consistently select the fastest band.
As a developer myself, I find it frustrating not being able to fix or debug some of these bugs. I really wish TP-Link’s firmware was open source so the community could help address these issues.

@Bader-bsn Thank you for your reply.
I can understand that the system may choose the band that has stronger signal. But this should be done only when it is in auto mode.
When I select and lock the band I prefer (because it is faster), I want the system to stick to this band, even if the signal of this band is weaker.
I really hope this relatively easy problem is fixed.
The only way to achieve the band lock is only if I also Cell lock. Which is not ideal because bands change PCI during the day.
Fyi I have not received my poynting antenna yet. I will keep you advised. Hopefully there is some software update till then to correct this issue.
