Third Party router decreases Sky hub speed substantially

[KWM]

Good Afternoon,

I recently bought the Sky Hub Gigafast package just about a week ago. I have installed a third-party mesh Wi-Fi (Netgear Dual-band AX1800 2 Pack MK 62) to the Sky hub. For the first few days the Wi-Fi seems to be working flawlessly, however last night I realised that the Sky Hub itself wasn't functioning properly. While the third-party router was working quite pleasantly (400-600 Mb/s), that is not the same for the Sky hub. It was giving out 5-20 Mb/s maximum. It was to the point where I can hardly look things up with Google as it was take about 30 seconds each search. 

I'm uncertain whether it is because of my third-party router, but I doubt it as when the Sky hub and the external router was installed, both seemed to be working fine without any problems (400-500 Mb/s and 300-400 Mb/s respectively). 

I know that fluctuations are common on the first 14 days after installing the Sky hub, however this has been a problem for the past 3 days already. As I plan to connect the Sky hub to my desktop via Ethernet, this may turn out to be a major problem as then I won't get the guaranteed speed of 900 Mb/s to my desktop. 

All help will be much appreciated and thank you for reading this far.

@KWM if you are trying to use both the Netgear and Sky hub's wifi at once you will almost inevitably have interference issues. Normally you need to turn off both wifi bands on the Sky hub if you want to use Netgear system. That is  unless you can ensure they dont use overlapping channels by default Sky hubs other than the Wifi Max SR213cuse ch36 to 52 (80MHz bandwidth) in the 5GHz band.but you can switch the hub to use a 40MHz bandwidth so ch36 to44 or 44 to 52.

Noted, I'll try to turn off the Sky hub's Wi-Fi. By the way, I heard that you can directly connect the router to the ONT. Is this true? If so, would you recommend connecting it directly or using the Sky hub instead? Thank you. @Chrisee

@KWM you can connect most Netgear routers to the ONT if you are in the UK you need to set the authentication to DHCPv4 Option 61 rather than PPOE and include the log on string which is

Understood. I'll connect it tomorrow. Thank you!

I have some questions to clarify: Why does the sky hub have poor speeds while my netgear is functioning just fine? Additionally, is there any tutorial on how to directly connect my netgear to the ONT? I'm a bit afraid as I might mess things up.
