Wifi speed slow

[calummclaughlin76]

 Hi there, I recently got FTTP installed in my home. I should be getting a stay fast download speed of 300 mbps and a max speed of 500 mbps. I have checked the speed into the router and I am getting over 500 mbps, great. However with using the smart router BT provided, I am only getting a speed of roughly 60 mbps over wifi. Does anyone know the solution to this? I am not expecting to be constantly getting 500 mbps but I would to expect to get roughly 300 mbps.

You are unlikely to get anything like the full speed over wireless, on a single device.

It was never intended that people get 900mb 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 900, take a look at the table below.  This is just for a couple of Apple Smart Phones and Tablets along with  popular Samsung models,

Apple (Smartphones)	Dualband (2.4 & 5Ghz)	Theoretical Max speed on 2.4Ghz connection	Theoretical Max speed on 5Ghz connection
IPHONE SE	Yes	60mbps	300mbps
IPHONE SE 2020	Yes	135mbps	600mbps

Samsung (Smartphones)	Dualband (2.4 & 5Ghz)	Theoretical Max speed on 2.4Ghz connection	Theoretical Max speed on 5Ghz connection
galaxy-s10e	Yes	135mbps	600mbps
galaxy-s10-5g	Yes	135mbps	600mbps

Apple (Tablets)	Dualband (2.4 & 5Ghz)	Theoretical Max speed on 2.4Ghz connection	Theoretical Max speed on 5Ghz connection
IPAD pro 3rd gen (Nov 2018)	Yes	135mbps	600mbps
IPAD pro 4th gen (March 2020)	Yes	135mbps	600mbps

Samsung (Tablet)	Dualband (2.4 & 5Ghz)	Theoretical Max speed on 2.4Ghz connection	Theoretical Max speed on 5Ghz connection
galaxy-tab-s5e	Yes	100mbps	300mbps
galaxy-tab-s6	Yes	60mbps	600mbps

Sounds like you are on 2.4Ghz and not 5Ghz.

Most clients are 2x2 so the figures above are in the rough ball park at max QAM for the WiFi standard on a set bandwidth. 

Do all your clients read throughput below 100mbps on WiFi when you are roughly 10ft from the router?

If so check the 5Ghz signal is broadcast by using a WiFi scanner. 

If it were me when I see an issue with these types of routers where either there’s an issue on the broadcast side or an issue where clients are sticky and not moving to the appropriate band I do a factory reset. 
For more control you would need a third party router that suits your requirements.
