Re: BT Smart Hub2 Erratic WiFi with Full Fibre 900 Hardwired

wifi speeds are never guaranteed and not sure what openreach engineer is going to to if your fibre connection over ethernet is giving full expected speed

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

Ethernet should ensure you get the maximum possible speed but I also appreciate that connecting this way is not always possible" End of Quote

Thanks for the reply.
My engineer has just been cancelled automatically as theres no fault on the line. But the Hub2 is awful and erratic - sometimes the WiFi connection is as low as 60Mbs now how do BT think that is acceptable when paying or 900Mbs. I'm on the verge of cancelling.
So frustrating.

the problem is more likely to be the devices than the wifi from the SH2

have you tried changing the wifi channels to a fixed channel rather than smart/auto? I would use a wifi analyser on mobile and see what channels are in use by neighbours then try and select a free or less congested channel. also if you have SKY Q then ensure the 5ghz channel is not set to 36 but maybe 44/48 as SKY Q uses 36

Yes have used an analyser and changed to 48 - no improvement.

Is the smart hub2 capable upto 900Mbs over wiFi?

Yes

Thank you for the clarification - I'm seeing the same in 5GHz properties as shown below but on fast.com wifi speed test my laptop is recording 270Mbps and my phone (Galaxy S21 5G) 390Mbps when both are near GB capable (laptop 867Mbps and phone over 1GB). So now I'm not sure where the loss of speed is occurring? The stated Link speed is that what's coming into the router as I can get that hardwired but the wifi drop off is massive...

Trying to assess if I need to request a new router or is there something I'm doing wrong?

As can be seen from both your screenshot and mine, the hub WiFi speed is not the issue.

I really can't understand this obsession with running speed tests that are usually meaningless. What on earth do you intend doing that you can't do with the speeds that you are getting on the individual devices?

Not unless you were using a 3x3 MIMO device - most are 2x2 and limited to 600Mbps real world throughput in ideal conditions (i.e. 80MHz channels with no local interference). For higher speeds you would need to look at a Wifi 6 access point and probably need more than one to provide high speeds throughout your house.

You obviously missed the 2 screenshots.
