Poor Signal Strength on Iphone From Fibre Broadband

alidolphin89 — Wed, 29 Mar 2023 20:05:16 GMT

We have recently moved to Full Fibre.

We can get a decent connection on our Macbook but struggle on Iphone.

This is a photo of our Iphone 13 which shows a comparison of speed on Fast.com

44MB on Iphone and 120 MB on Macbook.

Any help or suggestions appreciated.

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,

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

Thanks for your speedy response.

So when BT says 'it is our best Router yet' this is a clearly misleading statement.

I would say we were getting considerable better speeds on our mobiles across our house from our old Technicolour Router.

What would you recommend we do to fix this problem?

Thanks

What is the actual link speed to the router rather than throughput from a speedtest site? No idea where you find it on a iPhone, somewhere in network settings.

Hi @licquorice

Not sure what you mean by Link Speed?

When I am ethernet connected to the Router to my Macbook I get 150MB DOWN. The problem is the Iphone and the slow speeds.

If the Hub 2 does not support WiFi 6 then clearly there is a case for replacing this.

Thanks

Ali

Link speed is purely the speed of the wifi signal between your iPhone and hub and is independent of any broadband.

This is from my Android phone. As you can see the link speed is 866Mbps. As I only have a 40M FTTC broadband connection, it is irrelevant what my link speed is though.

Link Speed is clearly not an option on a Iphone unfortunately.

How quaint, even Windows shows Link speed.

The problem is clearly not the hub as both devices would be affected similarly.

On the iPhone go settings,wifi, click on the I button of the the relevant SSID, and disable private wifi address.
