Netia Internet Speed Drops - Fiber Optics, Huawei HG8245X6-10, Speed Test, Technician

I have had the Internet from Netia for several years, it is optical fiber to the house, Netia router (now replaced) Huawei OptiXstar HG8245X6-10. Bandwidth 1 Gbps. For over a month and a half, circuses with the operation of the Internet have begun. At random intervals, throughput drops dramatically, even to zero. Then after a while it jumps to the maximum level, 1180 MB/s. The technician, both on-site and remotely, determined that there was no interruption in the connections between the router and the control panel (equipment). There is no change in the diode signaling on the router (the same diodes flash the same). The problem manifests itself in specific lags, regardless of the type of connection: WiFi, cable via a switch, cable directly to the router.
The measurements taken at https://testujpredkosc.pl/speedtest show a decrease or increase in speed in the graphs.
I am uploading a PDF with the measurements and a few screenshots of these charts. Sometimes it even happens that the measurements do not start.
The operator recommended that I perform a certified Pro Speed Test. I`m halfway through (1 day, 6 tests) and 4 were OK, but two were terrible: about 30 Mb/s and just over 1 Mb/s. And until then he did nothing.
I hope you will be able to say something more after the test results. Or maybe you can even tell us where to look for the causes of these jumps?

I will also add that these measurements were made in a working environment, with a browser and devices connected to the network. I need a working connection, not a laboratory connection to measure reference measurements. Resetting the router doesn`t change anything.

Regards,
Jack

As it is optical fiber, neither you nor we can check anything remotely - as far as the service is concerned.

It may also be the fault of the operating system itself, therefore:
We download the latest Live image of the Linux System (the word Standard in the name).
https://cdimage.debian.org/debian-cd/current-live/i386/iso-hybrid/
Record the system image using Rufus on a memory card:
https://rufus.ie/pl/
Then, depending on what boots first, we set the BIOS to boot from the memory card and test it.
The system runs from the memory card, so it does not install anything on any disk.

I did not specify that it does not matter how the devices are connected to the router. I have the same problem on a computer or phone connected via WiFi, on a laptop connected directly to the router and on another connected via a switch.

Then you submit a telecommunications complaint in writing to the operator - there is nothing more that neither you nor we can do.
If there is a problem on any equipment, any device and any transmission medium, the operator must check everything.

Complaint about telecommunications services:
https://cik.uke.gov.pl/uslugi-teleko/pytania-i-odpowiedzi/reklamacje-i-skargi-faq/
Complaint in writing, including all evidence of problems.
In the complaint, describe exactly what we are demanding, how much money should be given as compensation from the date of the complaint until the defect is permanently removed, and how much money should be given for the subscription when the service did not work properly.
The rate for compensation and reduced abo is 1/30 for each day of the problem.
Specify that the response must also be in writing (it can be an e-mail, because it is also a written form).
The response should be provided within 30 days from the date of submission.
The deadline of 30 days for the operator`s response to a complaint is counted from the day following the date of submission of the complaint.
If the complaint is not considered within this period, it is presumed that it has been accepted (Article 106(2) of the Telecommunications Law).
If the response to a complaint is negative or unsatisfactory, the subscriber may apply to the Office of Electronic Communications for intervention or to conduct out-of-court proceedings to resolve consumer disputes (ADR proceedings).
A Consumer Ombudsman may also be helpful.

I know this, I wrote that the operator recommended me to do a certified test, and previously replaced the router.
I posted this post because maybe someone has already had such a situation and knows what the cause is. Maybe the test data I posted will tell you something, because they don`t tell me much. Maybe this will be a clue. The matter has been going on for a long time, I have been talking to Netia for over a month, they claim that there are no problems with the connection between the router and the headquarters.
Since Plus took over Netia, everything has fallen apart. This topic had not come up before, and if it did, it would be solved quickly. It`s annoying when I`m watching something and suddenly it freezes and there`s a circle in the middle. In a moment it starts and after some time it starts again. Or I`m looking for something on the Internet, click a link in the search engine and suddenly everything hangs and I wait for it to start. I do a test and it turns out that the speed is close to zero. And the operator is in no hurry to solve the matter, and there is no comparable alternative to Internet access in the area.
However, thank you for your tips and suggestions.

This is optical fiber, you can`t check anything here yourself, nor will the data from the modem tell you anything, if anything like that is shown there at all - that`s why there`s a problem with diagnostics from the side of the service, the operator`s network backbone.

Until you submit a written complaint, the case will not proceed.
Honestly, you won`t be able to get anything done because they will sell you off.

Do prospeedtests and report it to them as I mentioned above.

I will do the same. Thanks for the help.
Maybe I won`t close the topic for now, because maybe someone already has some experience in this matter.

Hey, thanks for not shutting down. I've now ordered Netia and I also have a similar problem, I wanted to ask how you solved it in the end? Because I don't know whether to cancel the service after all....

I have the same with Netia (1 gb fibre, Huawei HG8245X6-10): speed jumps from 0-1000 mb, connection drops (I have to switch between 2.4 ghz and 5 ghz or reset the router to get it to work). I have this on cable and wifi. Replacing the router did not help either. Is there a solution to this ?

I have noticed that this is a problem with one particular laptop in my case. On my phone and on other devices it works fine for me.

99% of the problems are on the client side.

Dirty system, too weak computer, too weak other hardware....
