Upgrading Netiaspot Router for Enhanced Range, Stability & Speed: Considering TP-Link, Netia CU

On Asus you need to set login, password, VLAN ID, encapsulation and PPP tunneling. The necessary data is in the appendix to the contract or you have to call the hotline.
Although in my opinion it still makes no sense - first of all, I bet you do not have a single client device with four antennas at home that can work with this Asus. Secondly, you still need to buy a third PLC adapter that will stand next to the main router, so it's easier and cheaper to turn on 5GHz WiFi on it. Thirdly, the Netia spot stays anyway, and you have not checked the wired connection so far - if the cable is ok, it is enough to turn off WiFi in NS, and leave the device itself, as there is a problem on the cable, the additional router will not help anything ( even if NS was in bridge mode). Fourth, each unnecessary extra device is 50zeta a year thrown away for no reason.

1.Of course, if the option with 5ghz, or a stable 2.4 in the area where we need the Internet, will satisfy us, then PLC is unnecessary.
I would like to remind you that Netiaspot works so dramatically that when you connect a laptop, tablet and 3 phones, the wifi almost stops working.
2. "Not a single client device that can work with this Asus" - here I would like to ask for examples. ??
3. The option to disable wifi in Netiaspot and connecting it immediately to the PLC adapter should I understand? I admit I did not take this option into account, a correct observation.
4. "Each unnecessary additional device is 50zeta a year thrown away for no reason." Here, too, I would ask you more clearly if you can.

Ad2. Asus has four MIMO 4x4 antennas. Only in this mode the real bandwidth will not be 10 times lower than what it says on the box. Your home devices usually have up to two antennas. In such a system, a much cheaper max 600Mbps transmitter is enough. The results will be identical (about 50-100Mbps) to the real transfer.
Ad3. As you write
Ad4. If Netia Spot in brigde mode and an additional router (powers of about 10W) work for a year, it will consume 2 * 0.01kW * 8760h * 0.6 PLN / kWh = 100 PLN. When you buy a router with an integrated VDSL modem, you will consume
energy only for PLN 50, i.e. the second PLN 50 is in your pocket every year. NS + Asus + PLC = PLN 150 / year, NS + PLC with WiFi = PLN 100 / year.

"When you buy a router with an integrated VDSL modem, you will use energy only for PLN 50, i.e. the second PLN 50 is in your pocket every year"
So, theoretically, you give the 3rd option: a router with a built-in VDSL + PLC modem? So I deduce from what you wrote

As for Companies - look for Asus, FritzBox, maybe you will also find something from Netgear.
Are you looking for VDSL / WAN hardware.

PLC also FritzBox, Devolo, Netgear.

If I did it at home, I would buy an additional AP that supports roaming (e.g. Unifi UAP) and connect it to the NS with a UTP cable.
You don't want to run wires, so I'd buy a pair of PLCs (both with WiFi) to get started. One was connected to Netia Spot and the other on the first floor. In NS, of course, he turned off WiFi. Both PLCs with an Ethernet port and the ability to work as a standard AP, should the electrical system prove to be in poor condition.

I don't think the installation is in poor condition, as I have mentioned before that it is new, there are 3 wires in the whole house, hence my willingness to go in the direction of PLC. 1 adapter connected to the router (here I am not sure if this one also produces a wifi signal), one on the way (it can be without wifi) to connect the TV via the cable. 3 adapter at the end to cover the farthest kitchen.
