Ubiquiti AmpliFi mesh networking kit

I have a Ubiquiti AmpliFi router & three AmpliFi HD (High Density) mesh points, with which I am very satisfied.

To achieve 100% high quality coverage in my 400 year old house, and my office (in the garden), I need to add two more AmpliFi mesh points.

I was about to place an order, but am now procrastinating as it has been suggested that each additional mesh point which I add will degrade the overall performance.

Is this really so?

In which case what are my options; cabling would be very difficult!

I honestly think you'd be far better asking the question on the Amplifi forums. Just as on the Unifi forums you get a fair mix of end users and Ubiquiti staff.

Many thanks.

I had considered that, but to use the forums it appears that you have to have a Facebook or Google account, which I am resisting.

Ah. I hadn't noticed that bit. Not good.

You can still use a regular registration on the Unifi forum. Try that and ask the question there on the Unifi Wireless section.

You wouldn't be the first to ask about Amplifi there - https://account.ubnt.com/signup?redirect=https%3A%2F...

You can try support with an email or chat 24/7. I have used Ubiquity chat before and they were very helpful.
