Replacing UPC Modem with Cisco EPC3928AD: How to Configure AppleTV and Dual-Band WiFi

Gentlemen,
I would like to refresh this thread on the example of my case. Well, I signed a contract with UPC for 250mbit, I got a Thomson, on which AppleTV did not work - a few calls to UPC and they exchanged for Ubee, now it works. Nevertheless, both Thomson and Ubee are tragic, branded with UPC soft, nothing can be configured on them (more than wifi) and they do not work simultaneously with 2.4 and 5ghz wifi, which totally disqualifies them for me because continuous switching between bands depending on the devices used in the home it is really a pain in the ass. So I did some research on the net and found this:
http: //www.klonex.com.pl/category/transmisja-danych/sy ...
I decided to buy a Cisco EPC3928AD and put in INSTEAD OF Ubee from UPC. And now the fun begins. I call UPC for technical support, where they pick up a guy who has no clue what he is talking about and keeps quieting me down asking someone behind my back what I am asking. And I asked a simple question what should I do or what should UPC do to make my modem work in their network - by asking this question, of course, I mean mac address authorization in their network. After 15 minutes of a exhausting conversation with the technical support layman, I gave up because it's a waste of stress. He obviously stated that there was no such option and would only work with their modem. I came up with another idea - at the time of installation, the technician uses the UPC installation page where he enters the modem's mac address to authorize it on the network - does anyone know such a page and have practiced it before to authorize his modem there?

I will add that there is no - I am not interested in inserting an additional router behind the modem from UPC, I want to have a 2-in-1 device, not 2 separate ones.

Greetings to those who fight for better internet and wifi

The problem has been raised many times.
NIKOM has not yet managed to persuade UPC to connect foreign (for UPC) equipment,
it also looks IMPOSSIBLE.
UPC has all its devices in its database, so a technician will not help here either.

It remains to confirm the statements of colleagues from previous posts. Money down the drain.

And is it not a coincidence that UPC simply has an agreement with the above-mentioned equipment manufacturers? Because it is probably not just a matter of the presence of a coaxial socket in the router?
Someone enlighten me ...

Sure, he has a contract with an equipment supplier and what's weird about that?

You don't understand the authorization problem. If it were not there, there would be thousands of foreign devices plugged into the network. Therefore, UPC and other operators allow access just own equipment

In the 21st century, I would solve the authorization problem like my previous internet provider. I drive to the Customer Service Office with my own router, authorize it on the spot, I return home and the internet is flashing on my equipment.

If they wanted to, they would have let him in, but with a minor exception.
Someone would have to add it to the base and additionally brand it with UPC software. So it basically doesn't do you any good.

I had a similar experience when I bought an STB for Jambox myself.
I bought a MAG254 instead of 250 because it has more RAM. It ended with the return and exchange for a lower version, because the software was not prepared, but only on their works.

The only plus is that I do not have to pay 10 zlotys for lease

That's the point, so that the user doesn't have too much control with the modem

You forgot to add the adjective "better".

Because I would even fire UPC something for the router / modem lease, but let at least the USB 3.0 connector be there, so that I could connect a network drive ...

authorization is not only after MAC, there are also hardware and firmware security

And how is it with these safeguards? Because honestly, somehow I don't want to believe that there are any reasonably good security measures on my Thomson. The more so that UPC does not try to even use a decent password to secure the router (even on portals it was written about it, there were a lot of break-ins on routers with "factory" passwords).

What to do then, how is such a shoddy router? What to stand behind him?
I dream of a mini linux server, but I don't have the money or time to configure it yet. What is worth buying to "bypass" the issue of a bad modem, since there is no chance to replace it with your own?

I saw an ordinary modem at the client's place, up to 150 Mbps + a fancy Tp-link (AC) model. On the phone, it pulled out 145 Mbps in the 5 GHz band and was very pleased. So it's possible

I am clear now. Thanks!
