Vectra 150 Mb/s Internet: Modem Router Guide, Cisco EPC3928S vs Technicolor CGA2121 vs Ubee EVW32B

Hey all of you.
As part of my efforts to make informed purchases. This issue also applies to the Internet.
In my area, it turns out that the only viable supplier is Vectra.
I opted for 150 Mb / s internet power. Here are my requests and questions.
This is not my first contract ... but I signed all previous ones like Leming - for FB to work it's good.
My observations and pseudo tests showed that despite the signed agreement for 150 Mb / s, the internet after WIFI was at the level of 10 Mb / s at most.
This is why
1.I would be grateful for some guide to what this service is all about and what influences such low or high performance.
2. Does the hardware matter here? At the moment, I got a proposal to use 3 Cisco epc3928s or Technicolor cga2121 or Ubee evw32b modems. I will be grateful for comparing these 3 devices and explaining why one is better than the other.
3. What parameters should the ideal equipment for a speed of 150 Mb / s have - so that the devices catch this speed after WIFI.
4. Proposals of the ideal equipment for such power (which VECTRA does not offer)
5. Is this WIFI performance possible?
Simply put, a joke ... I don't want to buy a Ferrari, which I will be standing in Mokotów traffic jams (Fiat 126p will also do for this purpose).
THANK YOU GREAT IN ADVANCE ALL FOR HELP !!

If you buy something, it's most often to use it!
Are you sure you need this speed?
I have a speed of 50 Mbps with Vectra for a very long time and it is quite enough for normal use. With standard hardware, you technically won't use more than 80 Mbps. You will not physically feel the difference while using the Internet - between 100 Mbps and 150 Mbps.

Unfortunately, Vectra gives me a choice of 150 - 300 or 600 Mb / s. I was asking for a lower speed for a lower price. However, apparently they do not have one or they have packages with a TV that I do not watch anyway.
So unfortunately I was doomed to those 150 Mb / s.

Take the 150 - no further conversation seems unnecessary. I have internet with Vectra (from the beginning as soon as they introduced this service) and as far as I know, it is technically one of the best.

But I don't think about power. A decision has already been made in this regard. As I wrote at the beginning, I would like to receive opinions on the equipment they offer. What is the difference between. Why is one better than the other and how to calibrate it or what to buy to get the 150 Mb / s after WIFI on home equipment.

I am sure that Vectra leaves no choice whatsoever for the user in this case!
After signing the contract, a technician's visit is arranged and he has all the complete equipment ready for the client. You as a user are not interested in what he will connect and how he will configure it. Believe me, he does it over and over and I was impressed with how fast! I cannot imagine that the client would buy anything else! According to my knowledge, there is no possibility of any choice. After connecting and configuring it, it does a speed test for you and leaves the premises in a hurry. You will get the equipment that they currently have in stock. The choice is 100 percent not yours.
I have this one at home now Technicolor cga2121 , I won't say a bad word about him, I don't know both of them from practice, but the fitter will explain everything that interests you more professionally!

OK MEN.
I see. I was given a choice of equipment. One of those 3, and I know what a technician visit looks like.
I would be grateful for assessing which one is good and why.
My next question concerns whether by buying the equipment on your own (modem) or by attaching a Router to the Modem (which you buy yourself), the effect of the received Internet will be better. Please, correct me if I have confused concepts, I am learning all the time.

Purchased modem cannot be connected. The modem is owned by the service provider - you just lease it! After the cooperation is finished - you give the modem to the owner!

Ok ... I understand that it is not possible to buy your xyz modem and connect it to be responsible for WIFI emissions at home. The possibility of sharing (leasing) the modem is licensed and only operators like Vectra can trade them, right?

The modem is not responsible for the emission of WiFi in the home. A router is used for this and you can buy one yourself and then connect it to the provider's modem.

Approx ! We are on the course. What the modem is responsible for and whether its model matters. As for the router, what to choose for such power?

You will get the modem from the supplier and you have no influence on it.
You can ask them to set it to bridge mode and the wireless router you buy will be responsible for the wireless network.
Do you live at home or in a block of flats? What size? How much do you want to spend on it? Do you have devices operating in the 2.4GHz or 5GHz band?

I live in a block of 80 meters. The apartment is on 2 levels. I don't know what frequency the devices operate on. How and where to check it? Am I able to switch to Bridge mode myself?

If there are many neighbors nearby, 2.4GHz will be sypy.
Download the inSSIDer program and show tabs from individual bands, if your computer supports 5GHz.

Can you see the frequency on your phone in the same way? Is there any program?

WiFi Analyzer.

Unfortunately, I don't have Wifi access here. How can I read it (attachments) where to check if the device supports 2.4 or 5 waves or if it is possible to change which frequency supports the device?

At 2.4GHz it's terrible crap and I wouldn't expect more than 20-30Mb / s from WiFi.

Ok, and how to make it receive on frequency 5? And will the connected router do anything?

The router must be dual-band, but the devices must also operate in the 5GHz band.
As for this band, the speed will be much higher, but close to the router, any obstacles such as walls, ceilings suppress it very much.
Overall, I recommend that you connect anything you can with a cable.

Ok, and will connecting the router to the modem increase the power of the internet via wifi even on the 2.4 frequency? And is it a good idea to connect 2 modems, one on one level, the other on the other? Is it possible or will they get stuck all the more?

Will it increase my power? Nobody will tell you that, you have a lot of noise in the aether. 2 routers are a very good idea, the second one is set as AP, connecting them, of course, with a cable.

Routers or modems?

Routers, I wrote above. The one from the operator will most likely have the ability to broadcast WiFi.

Ok, at the end, can any calibration of the modem give it better performance in wifi emission? And what router can / can you recommend for the technicolor modem?

For what purpose are you stifling this topic?
You report that you want Wi-Fi before the installer visit and decide whether you are buying a router or they can offer you!
They will connect and configure everything! With the current level of knowledge, the technical aspects of the matter should be left to the specialists.
Check with your signal provider if you have any doubts! Close the topic, because any discussion becomes pointless at this point.

I'm not the soul of the topic. He adheres to the principle that he wants to have knowledge himself and not take his word that it will be fine. To sum up. 1. Connect a router to the modem that the operator will provide me with, which is best placed on the 2nd level of the apartment. 2. Which router do you recommend. 3. Again. Will your own hardware calibration do something about the power of the received internet?

1. The operator's modem must have WiFi and is to be connected to the one on the first floor via a cable ONLY.
2. You have not replied with what budget you have at your disposal.
3. Yes, you can set something up there, but don't expect any miracles from WiFi.

The budget does not matter. I would ask for recommendations of something proven.

Unifi AC Lite or Pro can be used as AP on the floor.
