Huawei B525: Low LTE Speeds, Download & Upload Issues, Antenna Solutions with T-Mobile Contract

Hello. I have a contract with tmobile for unlimited LTE 60 Mb / s internet. I used to have this contract, i.e. a few months ago, but I took advantage of the return due to low speeds in the evenings and terrible drops. Today I decided to try again, to my surprise the maximum download for LTE is the whole 2 Mb / s, while the upload ranges from 8 Mb / s to 12 Mb / s. I read somewhere that this is probably the fault of the loaded relay. The point is that the upload is much larger than the download, but sometimes the upload drops even below the download speed. It is quite strange because a few months ago the Internet was even 50 Mb / s per second at night. When it comes to 'dashes' it is currently 1, sometimes there are two, it never goes above 3. I completely don't know it, I don't know how to set it up, maybe I could do without an external antenna, although I doubt it. This time I don't want to return the device and withdraw from the contract (the only other available in my region, no limit is two Mb). Generally speaking, I don't know what to do. The router is Huawei B525. I add some signals, they are probably weak:
RSRQ: -9dB
RSRP: -97dBm
SINR: -4dB

@Edit: Now the internet has gone up a bit, up to 6-8 Mb / s download, 15 Mb / s sending.

Normal situation if there are too many users. Signal strength is good, but SINR is weak.

Provide location.

Show screenshots, select different bands and aggregations, do speedtests and give screenshots.

Very normal situation.

I checked a little bit, I got the best results on the auto function, without selecting any band.
I also send all screenshots I made during tests: https://imgur.com/gallery/YwuUg

In the 2600 band, the range is relatively weak, but this does not necessarily mean that it will malfunction. 1800 pretty good, similar to 800. I personally don't see the need to buy the antenna, it's not far to BTS, everything works as it should. Repeat this speed test in hours of lower load, even now. The worst upload indicates that the signal quality is ok, only the load from other users does not allow for higher speeds.

Speeds from now:

It's a pity, I don't know if it pays to pay 60 zlotys for 2 Mb / s during high intensity. [/ Quote]

Well, it's LTE and the offer is very favorable, people take it and the network is clogging. There is nothing you can do about it. If you have no other alternative, then you have to use T-Mobile, somehow it's not bad?

And where exactly do you use this T-Mobile because interestingly for the car and LTE1800 is the BTS LTE1800 at the top of Mużeń. Only LTE1800 works there. LTE2600 + 800 is BTS Kurów. Parameters naLTE1800 sufficient but not crazy, LTE2600 as the baseband in aggregation with LTE800 and here the signal is weak. Take the LTE2600 + 1800 and LTE1800 + 800 test.

It is not bad, but I would prefer to pay for 60 Mb / s instead of 2 or a little more when the intensity is high, well maybe soon relieve the network, or there will be some other solution.

As such, there is no difference between the auto mode, at the moment that is at 3pm there is 15 Mb / s download and 15 Mb / s upload.

On all screens, B525 only connects to LTE1800NetWorks at the top of Mużeń. , band aggregation did not work under any circumstances. Is the location around Kunów?

Exactly.

@Edit: I also noticed that sometimes there are significant ping increases, literally for a few seconds. Also sometimes the internet just loses power to recover it again after a few seconds, but a moment ago I had to restart the entire router to restore the internet.

Every now and then disconnects my internet, as if the router was losing the signal, I think I will try the antenna, check if the situation will improve, I will give it back.
