Hi Deco Community!

I hope you can help me!

Iam using today a classic deco M4 Network in Router Mode behind my ISP Modem. Everything ist working fine.

I have one room in my house which is a litte far away and the WLAN Connection is not running good and sometimes it drops.

So i plan to extend my network and i want to use a PLC Backhaul to connect this extended room. 

Now my questions are;

 - i would change my main router from M4 to P7 or P9 to use the PLC

- the other 2 M4 devices are connected via Ethernet Backhaul

Can you give me a advise which device i should buy? P7 or P9

Are these devices complete compatible or could there be a problem i have to check first?

I have read about many issues regarding the P9 device? are this problems fixed? The faster AV1200 PLC Backhaul would be great instead the slower AV600 Backbone in the P7.

Thx for your help!!!
