Hi,

im after some advice, I've got 3 P9's round the house and I'm looking to expand / increase (speed) the WiFi in certain areas of the house and wondered what would be the best option?

ive looked at the new x20 & 60 and would one of these play nice with the P9's - As the X series is a newer device I'd use it as the main deco but would the power line back haul still work on the P9's also as the house is an old Victorian five bed with quite a few rooms and many walls. 
 

currently, with the P9 coverage is good but in one room in particular the speeds aren't great (shame that's my office currently). 
 

Any advice greatly appreciated
