Windows 10: Wifi speed on Lenovo laptop

I have a Lenovo laptop with a Broadcom wifi adapter, the upload and download speed has fallen through the floor along with network drops outs.

The laptop is running Windows 10 1909, the laptop is currently running Microsoft wifi adapter drivers, I have downloaded drivers direct from Broadcom but the performance was even worse using the Broadcom drivers. I have checked with the Lenovo web site and according to the driver support I have upto date drivers.

I have checked wifi performance using speedtest.net on my phone sat next to my laptop and I am getting the expected broadband speed. My son has also tested the wifi speed on his PC upstairs and it is only slightly less than expected broadband speed ( to be expected based on distance from the router etc.). My broadband speed is 100+Mbps on average, the laptop is giving just 10Mbps.

Can anybody make any suggestions on what I can do to get the laptops wifi performance back to wear it should be please.

WiFi internet speed running slow on Windows10 Lenovo U31-70 laptop

Hi,

I have a Lenovo U31-70 laptop which I bought in August 2015. It had Windows 10 pre-installed at the time of purchase.

Since last 1-2 months I have been observing that the the WiFi internet speed on my laptop has become slower. If I go to speedtest.com and measure the speed, I see Download speed=5Mbps and Upload speed= 0.5Mbps on Lenovo laptop. However, if I measure the
net speed using my 3years old Windows 7 Toshiba laptop, I measure Download speed=55Mbps and Upload speed= 5Mbps.

I am wondering if this is a Windows 10 problem or something has happened to my new Lenovo laptop suddenly. Any suggestions to debug and fix this problem?

I have tried installing this driver but doing so (followed by system restart) doesnt improve the internet speed: Intel WLAN Driver for Windows 10 (64-bit) - Lenovo U31-70 - DE

 

wifi speed degradation in win 10 laptop

I am more confused now. I have 100/100 Mbps fios. the laptop achieves a speed of 101/118 when it is restarted. that to me means my settings are proper. Within 24 hours the upload speed drops to near 35-40 Mbps. At that point a simple restart of the laptop
brings the speed back to 100/118 Mbps range. That to me suggests that some processes within the computer are limiting the upload speed. all other computers are working at the specified FIOS speeds. I have tried using Ethernet as well as wifi.
