Ok so i got the latest firmware installed yesterday, thnks for that. Now the options are the same between the Deco P7 and the M5 i got.

Also i can now see to wich of the Deco's my devices are connected, great.

But, before i noticed that the new firmware was available my daughter was upset and complaining about loss off internet/wifi on the PS4 she was playing. When i tested the network speed i saw massive drop of speed and it was also very unstable. Also the tests i did with my phone and Speedtest showed very unstable and an dropping speed. (i got 250MB down and 25 up connection) And it got dow to 10mbit.

Luckily at the same time last night the update for de P7 arrived and installed it. Afterwards connection was a bit sluggish but af resetting and testing al the conected lines and wires it seem like its stable now and also is gettig higher speeds.

But.....,the strange thing is now that i can see to wich Deco the devices are connected. The PS4 does not connect to the nearest Deco but to the Deco one floor below. And this is through ethernet and not wifi. All the devices from the top floor are connecting to the deco one floor below... strange.

I disconnected the deco 1 floor below and kinda forced the PS4 to connect to the nearest Deco. This worked. But now the next day al the devices are again connecting to the Deco 1 floor below. Speeds are kinda ok but ik dont think it is the right way to connect right?

Situation is:

Bottom floor

Internet -> Deco P7 as main deco -> Switch -> ethernet Nas and to Deco P7 first floor
Deco M5 in Wifi mode for main living room

First Floor

Ethernet from switch bottom floor to Deco P7 on first floor -> Deco P7 on second floor

Second floor

Ethernet from switch first floor Deco P7 to Deco P7 on second floor -> switch and connects to PS4 and other

So why dont the devices on the second floor connect to the Deco they are directly connected to on the second floor, but are all connecting to the one on the first floor???
