BT Smart Hub 2 dropping 1 device constantly - how to fix it?


[link to this post]
 
Hi, my BT Smart Hub 2 (FTTP 150Mb/s) has started dropping one laptop device from my network repeatedly. It happens when I'm just generally working and on video calls etc. It reconnects sometimes after a few seconds and other times I have to manually trigger it.

BT suggested it could be a VPN issue but I don't use one. They "dialled in" to the router but said it all looked fine. They told me my Sky Q box could be causing it by bombarding the router with requests for info(?) and to reset the box it but it's made no difference.

The log shows these entries for a couple of recent times it's happened. I have no idea what this stuff means and when I read some of it out to the BT support they didn't really explain it or suggest they heard anything that was a problem.

As it's only one device I'm wondering if it's the device or the network?
Incidentally the range on the hub has gotten poorer lately and I've been considering replacing it with something else but want to figure out if this is the laptop or hub first.

Any help would be greatly appreciated!
Thanks.

Windows 10 Pro Surface Laptop, Core i5 7300, 8GB RAM, all updates installed, wifi driver up to date.
Wireless channels 2.4GHz = 11 and 5GHz = 48.
Wireless mode = Mode 1. BT Support suggested changing to mode 2 but warned it comes with some performance drop(!).

"Reason:Deauthenticated because sending station is leaving (or has left)" seems to suggest that the problem is with the laptop. There are lots of reports of similar issues on Microsoft support forums. Just one example here and oodles and oddles here

Hi,

Have you tried to connect the laptop via ethernet? Might solve your issue.

Sadly the laptop doesn't have a LAN socket and only one USB so I'd have to buy a powered hub of some kind to enable this.

Hi,

I use a non-powered 7 port USB 2 hub personally...Cost about £20 several years ago...also have a 4 port USB 3.0 hub which I got last year for less than £20 on Amazon (search for Sabrent on Amazon).
