Slow WiFi until Change Setting On Adapter. Then Eventually Slows Again
Hi All,
I have a very weird problem and after some help if possible.
I have a rock-solid 100Mbit cable connection and my laptop is only a couple of metres away from the wireless router.
I check the speed at Speedtest by Ookla - The Global Broadband Speed Test and get an unstable speed reading that peaks at about 40Mbit. I will retest 10 times to ensure the reading is accurate.
I then go to Device Manager and open up the properties of the Wifi Adapter and change any setting (such as preferred band) and hit 'ok', the adapter seems to restart.
I then go to Speedtest by Ookla - The Global Broadband Speed Test and it is a rock solid 98-99Mbit for 10 tests.
After a while, it will eventually slow back down again. The only solution is to go back to device manager change a setting in the WiFi adapter again, which immediately speeds it back up.
What I have Tried:
Tried multiple drivers for Wifi Adapter.
System File Check
Fresh install of Windows 10 (last week for another issue)
Disable DHCP and Set manual IP from PC settings
Reserved an IP on router side
Just about every combination of settings in Wifi Adapter
Any ideas what could be causing this behaviour?
Any help greatly appreciated.
Cheers
Mick
