Smart Wifi Pro slow... < 10 Mbps

I've got a 900MB service, a Smart Hub Pro connected to a Smart Wifi Pro by gigabit ethernet (cat 5e I think), via a switch to stop the connection dropping. After initial start-up of the Pro, connecting to it via 5Ghz wifi, I might be getting 850Mbps or so (no issue there). After a period though, this drops to < 10 Mbps, across devices, regardless of how close they are, with only 3 or four connected devices, two of which are inactive. Speeds are normal for devices connected directly to the Hub via ethernet and wifi. When the Hub Manager interface eventually loads, it'll show the Pro extender having a 'Good' connection at 1000 Mbps via ethernet.  

I've been searching for a solution to this for ages and not found anything, hoping someone has some insight?

@JK130 The EE PRO and Smart Wireless are they not all 2.5Gb/s Ethernet high speed interface, and as far as it has been reported before they are very cable picky in operation, do you know that the backhaul is working as expected when testing between the devices. 

Do not rely on the software to tell you what the speed is, it did have a reported bug in it so not sure if it ever got round to displaying correctly the actual connection speed!

I was getting speeds around 850 Mbps ish via Wifi from the extender for the rest of the day yesterday, having reset the Smart Wifi Pro. 24 hours after that, however, it was running slow again, back down to 9.5 Mbps over WiFi. I connected a device directly to the Smart Wifi Pro via ethernet, using the remaining available port, and got a similar 9.5 Mbps max speed. I took the cable from the Hub to the Smart Wifi Pro and connected that to my other device, and got a result of about 925 Mbps. Then reconnected the Smart Wifi Pro to the Hub via that same cable and speed was back to 855 Mbps via WiFi.

@JK130 The cabled backhaul up to the EE Smart wireless device, you have already said that you have a switch in the mix, so unless you get it all out off the loop there is not much more can be done or said, the fact you pulled it out is off no significance in the slightest, something is clamping the operation and reducing the speed that the Hub thinks, it's folding back in operation and recovering by the looks of it removing the Ethernet Connection.
