Slow WiFi on BT Hub6

[ssrco02]

We used to have a wifi speed of about 6Mbps but it has recently dropped to just under 2Mbps.  No changes to anything else. One of our laptops is only about 4 feet from the hub so any suggestions to fix it please? 

The PC connected directly gets about 40Mbps.   I have already tried the obvious hub restart and also switching Smart Setup on and off.

If Windows laptops are your network drivers up to date as even 6 is a big drop from the wired 40?

Just thinking we had a big Windows 10 update the other day,  I wonder if that has messed things up?

[ssrco02]

Just ran the same wifi speed test from my mobile and that is getting 7Mbps both ways so it certainly seems it could be a Windows problem.

Googling "slow wifi speed windows 10" throws up a list of a few things that may help. Good luck

Hi, I suspected a problem with the driver for the Realtek wireless LAN adapter after the latest Windows10 update. I didn't like the look of the various offers of driver updates available as they are all trying to sell me something. Finally I disabled and re-enabled the adapter and the speed is now back up to 20+ Mbps. What a pain.

Have you tried seperating the 2.4GHZ and 5GHZ bands? also make sure you're using Wireless Mode 1

[ssrco02]

Yes the 2.4 and 5 Ghz bands are on separate channels and Wireless mode is 1. All seems OK since I did the disable/re-enable on the wireless adapter so everything crossed here.
