Windows 10: slow upload speed while using wifi on laptop

I have a problem with wifi upload speed. It's too slow. When I do speed test the download speed is good about 60 mb which is good in relative to my internet provider and country. But the upload speed begins at about 17 mb which is good then decreases fast to less than 1 mb. the problem occurs only while using wifi in the laptop ,and doesn't occur while using ethernet, and doesn't occur while using other devices with wifi. I am using windows 10. I will be glad for help.

slow upload speed

I'm embarrassed I didn't think of plugging the ethernet into another computer. Anyway, the result is that the speed on a laptop with the same cable is 91 Mbps download, 39 Mbps upload.
A couple of other puzzles: One is that the download speed on my desktop was around 900 Mbps, which is insanely fast, but the upload speed was under .2 Mbps. Now, after going through several of these iterations of remedies, the upload speed is still extremely slow, but the download speed is now around 32 Mbps, which is about 4% of what it was. But to my surprise, with a download speed of around 30, I don't notice too much difference for what I do. Anyway, awaiting your next suggestion.

With regard to re-installing Windows 10, even with keep my files this seems to be way over the top, as it removes apps and drivers. I find that a bit terrifying.

I don't know if it will help, but some things to try.


Open the Device Manager
Go down to your networking
choose the wifi or ethernet connection
and double-click on it to bring up properties move over to the power management tab and uncheck both options
on the advance tab scroll down to large send offload ipv4 and ipv6 and disable both
reboot.
try speed test again





also disable any green, powersaving mode, or energy efficient modes

 

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.
