Welcome to this user forum for BT Retail phone and broadband customers.
You are never going to get the full speed on wireless, and no ISP, including BT, will guarantee wireless speed, only the speed on a fast computer directly connected to an Ethernet port on the home hub.
Connection to the discs are still over wireless.
You are unlikely to get anything like the full speed over wireless, on a single device.
It was never intended that people get full speed on all devices, especially on a wireless connection. The intention is to allow that bandwidth to be shared among family members and multiple devices, without each user noticing any slowdown.
Here is a quote from old post by @SeanD on 18/06/2021
"I think for the first time ever we are in a situation whereby the speed you can now get through Full Fibre outperforms the capabilities of many devices.
The Smart hub 2 does not come with Wi-Fi 6 but this is something we are looking to include in our next generation of Hub. I don't have any info as to when we will launch a new router by Wi-Fi 6 will bring some improvement.
As an example of what I mean in terms of devices not being able to support the full breadth of speed available on Full Fibre , take a look at the table below. This is just for a couple of Apple Smart Phones and Tablets along with popular Samsung models,
