Lounge is below the Main Deco/Office. Looks like 500MbS, but it's not the speed, but the signal drops mostly.

I'm struggling to understand the best way to set up my network. Please see the below. I find that the Dining Room deco frequently gets "lost" and the Kitchen Deco usually has a really weak signal....

I have a 6 room terraced house and 5 decos. I'm not sure which is where without taking them off the wall, but it's something like this: 1st floor: P7 Main (office) -> nothing (bedroom1) -> P7...
