I've just got 3x XE75s and I'm disappointed. Not able to get speeds above 500Mb - the Virgin Superhub 5 was delivering that before.

It's on AP setting and Superhub has wifi turned off.

Worst thing is that the connection in the garden is worse than ever - what a waste of £330

Just saw this reply,

I ended up changing the TP link XE75 3 pack for the Asus XT9 two pack and single extra XT8. I can get 700+ over wireless XT9 node in my loft conversion. Also allows manual channel selection and USB Media sharing ( have a 4tb HDD with films via DNLA) Was more than happy with the Deco M9 plus 3 pack i have on standard copper fibre ( BT 70mb) but upgrading to superfast i think TP links implementation of DFS , not being reliably able to use the 160 band without the stupid strikes.

Being able to manually select wifi  channels for 2.4 GHz , 5 GHz  and the actual wireless backhaul  gives you scope to find the channels that work for where you are located region. Also the Wifi 6E is generally not worth it as it seems to have slightly lesser range than standard Wifi 6 which is still very fast when working well. 

Hopefully this setup will last me until Wifi 7 get mature enough to invest in.
