LTE Plus Internet Poor Performance: D-Link DWR-116, Huawei E3372, AK C2 Uni Antenna, Płaczkowice

Hi
I have a problem, to the point:
I have LTE internet from Plus and unfortunately it works very poorly:
The router I have is D-Link DWR-116 in which I have connected the huawei e3372 model
The antenna I have is the AK C2 Uni that I got on Plus

On the router side signal strength and power: (-79dBm) and 4/5 range bars.
I live in Płaczkowice in the province Swietokrzyski
Help, and I have a question in which direction should the antenna be mounted on the transmitter? Currently I have set up for Klimontów.
I am completely green in it, best regards.

Edit: I forgot to add speedtest

Have you tried checking, for example, by inserting this SIM into your phone? I live in Chorzów. I used LTE faster than WiFi at home. Now, after a few years, I can't have LTE, because the signal from Plus is so weak that it's a shame to talk. They broke with one word. Advertise with them. Ping is at a good level.

But you don't have an antenna, just a silencer, because this is how Akc2 uni works. You won't set it to any BTS because the junk has omnidirectional characteristics, it's electro-junk. In addition, a fatal choice of the operator with weak equipment, The speeds shown are evidence of an overload of the BTS. It is not known whether it is a LTE or 3G connection and with which BTS and in what band. The nearest operating BTS LTE1800Aero2 is Borek Klimontowski, there also LTE800 Sferia. LTE1800 Aero2 also in Wojnowice, there also LTE800Sferii. UMTS900aero2 in Klimontów. E3372 from Plus to HiLink, works with http://www.lte-anbieter.info/ltewatch/count_huawei.php?Datei=ltewatch_h Download, install on your computer and log in to the program on E3372 located directly on your computer. You force LTE800 and LTE1800 in turn, show program screenshots and speedtests. LTEWatchH shows BTS-a-CID data and LTE signal parameters. Plus, it's rather not an operator for this location. And don't advertise anything because it's a waste of time, it's a service without a speed guarantee. You need to check how nearby LTE1800Aero2 BTSs work and force a connection with the least loaded dual LTE1800MHz directional antenna.
