WiFi speed massive drop

[kjwng8]

Hi all,

I have had full fibre for a while now. Usually I'm getting around 900-950 down to the hub via the cable and then via any wireless device I normally get 750-850 roughly. Lately that speed over WiFi has dropped to around 350-400. No changes to my network, no new devices etc. I tried factory resetting the router, went via BT support all to no avail. They sent a new router out which came today. I've set it all up and only connected one device and the speed is still around d 350-400. Anyone experienced this before and managed to fix it?

Cheers.

Probably just congested wireless channels, not much you can do about that. Its also going to depend on the wireless device itself, why would it need that sort of speed over wireless?

Best to use wired connections.

Well, I'm trying to figure out why it would drop so much when there have been no changes as far as devices etc. Wired connections not possible due to where the router is. Would just like to try and get the speed backup where it was if possible.

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 what one of the moderators posted a while back.

"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."

You might not have made changes to your devices, but neighbours could have made changes which interfere with your WiFi.  I'm amazed you ever got such high speeds - mine tops out at about 300 Mbps, which is more then enough the vast majority of the time (and I get 940 Mbps on wired connections when I need more).

I can see a new medical condition, which I'll call Full Fibre Paranoia, being recognised soon. 😁
