Question powerline speed drops when netflix starts

Hi all

First I'll describe the current situation.

I live in an old house so there are no ethernet cables in the walls. Therefore we needed to use powerlines.
Our telecom distributor (telenet) provided us with some powerlines (Topcom 200 85 mbps) many years ago because the modem is in the garage and there wasn't enough coverage in the house. So 1 of the Topcoms is in the garage connected with the modem. The other 2 are in the living room (one connected with an AP and one connected with the digital tv box)

Few years ago I descided to move my room upstairs and therefore, internet was needed in this room as well.
I bought TP-LINK AV500 (TL-WPA4220KIT) to get this done.
The guy at the store told me these powerlines were not able to connect with the older ones (because of the difference in speed 85 mbps vs 300 mbps) so 1 of the powerline is connected with the modem in the garage, the other one is plugged directly into the wall (no extension cords) at my room

When I test the speed directly at the modem, I have 150 mbps down (up I don't remember)
When I test the speed by a laptop connected with the powerline at my room, I have 40 mbps down and 17 mbps up which is ok

Now, the issue is when someone is starting to watch Netflix on the smartTv in the living room (connected over WiFi, coming from the AP in the living room). From this moment, the download speed at my room drops directly to 1 mbps and the up to 0,18 mbps

Does anyone have an idea how to solve this issue as this is not workable
 
Toss them all in the trash and buy av2 units. You could I suppose toss the av200 ones and buy more av500 but the newer av2 units do not cost much more and work much better.

You can run more than 2 powerline units in a network. So you could put 1 unit by the modem and then 3 remote units. The newer units in theory you could mix the av200 and av500 and they would all run at av200 speed. That works fine in theory but there still seem to be issue running equipment from different manufactures. The newer stuff works better but I still see people complaining about some of the lessor known brands.

The reason it does not work to have a pair of av200 and a pair of av500 units is they interfere. 2 pair of even the newest av2 units have the same issue.

Rather than run as single network they both think they can use all the bandwidth. The signals stomp on each other. It will kinda work if the traffic is low enough because if you get lucky they will not both send data at the same time. When you start using stuff like netflix it transmits data at a fairly high rate almost constantly so it greatly increases the chance the other signal is getting corrupted.

Thanks a lot for the reply
Do you have recommendations for powerlines (I need 4 if I understand your answer) that are good?
I can't really say what my price budget is as I don't have any clue what a reasonable price is
 
There are 2 basic kinds of av2 units mimo and siso. Used to be you saw numbers like 600 and 1200. Now you also see 1000 and 2000. I am not sure if these are just different fake number or what. They are all fake numbers.

Tplink units tend to get good rankings.

This site has some test results. It does not have all models but should give you some guidance as to what to expect.
