@frederikk I'm planning to connect all the slaves ( E4s) to the main device (M4) that is connected to my router via Ethernet cable. I really hope I could get somewhere around 200 Mbps, which is my current internet speed rather than the 95 Mbps that I'm currently getting. 

@Muji if you go through the main deco, you should be able to have the new features. there is another post about that, i answered, but we are waiting for official statement from tp-link.

for the speed, it depends on a lot of factors unfortunately....ans your main will be the bottleneck as it will concentrate all the traffic. but if it is a more powerful one, might be possible.

@frederikk I have read that it is possible to connect different TP Link devices together but I'm worried about the speed. I only need it to be close to the 200 which is the speed I am paying for. I have already bought an M4, and I hope the combination works. 

@Pseaman66 

But why its not around 300 mb on all decos . even i am having same issue i have 1 m4 and 3 e4 but i am getting 300 only on main deco . other are giving only 150 mb

@Muji i tried , I have 350mb plan and earlier i was having 3 deco e4 . only providing 90mb max speed . but now when i installed one more deco which is m4 as a main deco . i am getting 320mb from main deco and rest giving 1

50 mb maximum. Not satisfied .

I think there's some limitation. If someone is using all 3 m4 deco please let me know what max speed they are getting ? Thanks

I understand your pain. Honestly I have given up on Deco series  & gone ahead with a second broadband connection.

Specifically on Deco E4, suggest be happy if you are getting a stable/consistent speed of 150

@Muji Did it work? I have the same problem.

@Kevin_Z Thanks. I hat decided to go ahead with option 2. I am able to buy Deco M5 single piece in my country.

 

Follow up query - I can see Deco M5 provides many advanced features (homecare, antivirus etc.) which are not supported by E4.

 

I wanted to know if I use M5 as my master node, will I be able to utilise these features via the E4 slave nodes

@Himanshu_IN 

Hi! I am also considering adding an M5 to my existing 3-pack E4. Did you get the additional M5 features (like speed test, homecare, etc) when you made it your main node even when connected to an E4 node?

  @Kevin_Z Option 2 works great...

Main Node:

DECO M5, First Floor Hallway.

Satellite Node:

DECO E4, Ground Floor Living Room.

Some loss in transfer speeds is to be expected in the satellite node. That said there is better 2.4 ghz coverage and transfer speeds.
