With Deco mesh, there is also another option. Keep your ISP Router (hub 2), turn off its WiFi and run Deco mesh in Access Point mode to provide WiFi over the house.

Benefits of that approach: if you have issues with broadband link, your ISP Tech Support will be less dismissive when you use their router. The moment they hear "Deco" they'll reply "it is third party router" and they'll tell you it is not their equipment fault. Unless you are quite technical person, and even if you are, overcoming that initial dismissal could be challenging.

Also, in that setup if you don't like Deco WiFi mesh and want to replace it with different brand, you will not need to change your network settings: IP address range, IP addresses reservations, etc. Power off Deco mesh, configure new WiFi mesh, and you are done.

If you are interested in that option, I can discuss it in more details with you.

Hello Alexandre,

Many thanks for responding so quickly.

Understand your approach...

With my bt router I have three deco m5 1300ac's, which I will replace, of course.

What I want is to make best use of the incoming 900Mbps stream, throughout the house.

Xbox's, 4k streaming over 2 or 3 tv's, quite a few phones and tablets.

So, I am open to any system you can suggest, which will deliver...

I reckon wifi 6 AX dual or triband? Would like to future proof if I can.

Three bed house, largish downstairs and reasonable size garden

Let me know what you think?

Sure, no problem.

For upgrade from M5, on gigabit home LAN and gigabit Internet link I am going to suggest you the following options, with WiFi6.

1. Deco X55. It is dual-band, but reasonably good device by price/performance. 

2. Deco X68. Should be similar in performance to X55, but it is tri-band.

3. Deco X90/95 - top of the line WiFi6 Deco offer from TP-Link. It is tri-band. A bit on a pricey side comparing to X55 and X68, but with maximum range and performance you could get from Deco X-series.

If you want to try WiFi6E, consider Deco XE75. Note that there are two other similarly sounding model names: X75 and XE75 Pro. Do not buy those, what you need is XE75.

Unless you live in very WiFi signal congested area, WiFi6E won't deliver much benefits on gigabit LAN/Internet speeds. Also, 6GHz band used with WiFi6E travels shorter distance and more sensitive to obstacles. When distance matters, WiFi6 is better than WiFi6E.

In case you narrowed choice to be between X90/X95 and XE75, I'll recommend X90/X95.

One more thing. You can combine indoor WiFi6 mesh with outdoor unit to provide better coverage in the garden, if you want to. There is just one Deco outdoor model to choose from: Deco X50-outdoor.

You can deploy new indoor Deco mesh first and then decide if you need outdoor unit.

  @Alexandre. 

Many thanks.

I will look into those options and will choose one of them.

Very much appreciated.

Regards

Peter

One more thing... if I stop wifi and connect mesh to the hub2, will the full 900Mbps go to the Deco mesh system?

  @Peterb02 

Main Deco has gigabit Ethernet port. hub2 should have gigabit Ethernet ports. So the answer is: yes. 

You also have another benefit of splitting the load between two systems: hub2 CPU will be in charge only of network management while Deco mesh CPU will only be in charge of WiFi. It is like doubling home network performance for free.

Wonderful. Thank you.
