My building is concrete so I get no Wifi signal on the 2nd floor. I use a powerline adapter to connect a Deco M5 on the 2nd floor to the main unit on the 1st floor. This uses the "Ethernet backhaul" functionality of my Deco M5 (your E4 also supports it). The WIFI speed on the 2nd floor is therefore limited to what the powerline can manage. The other Decos operate at max Wifi speed. 

 

The way you have explained your setup, you won't be using backhaul -- the main Deco will use the powerline device to connect to the router. This means all the devices in your house will be limited to whatever speed the powerline adapter can give you. My experience is they usually don't get faster than 8MB/s, but it depends on the adapter and the electrical system in your house. That's the only downside, and it might not be a problem, but if you are paying for high speed internet you probably won't achieve the max speed you are paying for.

 

BTW The Deco PX50 and P9 systems have powerline capability built in, so you don't need extra powerline units.

  @Neill78 thank you so much for your reply.

 

I'm a novice and I think I follow (I pay for 1GB wifi btw).
 

Is there a solution to my problem? Will I not have the same issue if purchase the PX50 or P9 systems? What do you think is my best option?

 

Cheers.

And are you saying there’s no point using a powerline adapter for the main deco next to the router?

  @Psyurmh 

 

David-TP gave a good answer.

 

Your solution will improve the Wifi signal but your total network/internet speed may drop because all the traffic will go through the powerline device, and they are not usually very fast.

But if you are currently having connection trouble or speed issues, the powerline adapters will probably solve it.

Thank you.
 

With my current setup (ethernet cable from router to main deco), should I select the operation mode to AP mode in the Deco app? Instead, it is currently set up in wifi router mode and I'm wondering if that could be a contributing factor for the poor performance.

 

Alterno, should the deco be in WiFi router mode, but the main deco doesn't need to be near the router and/or connected by the Ethernet cable?

Sorry for the basic questions.

  @Psyurmh 

 

If the router/modem from your ISP is actually a router and not a modem (more than 1 ethernet port), then it might be a good idea to switch the Decos to AP mode. It MIGHT improve your performance.

 

Also, if the ISP router has wireless, you should turn its wireless off and let the Deco handle all wireless traffic. Part of your performance trouble could be wireless interference.
