Wi-Fi shows a very low speed Windows 10 Laptop

For past several months, my Dell laptop running on updated Windows 10 shows a wifi internet speed of only around 4 mbps whereas the actual speed is around 25 mbps and tested on other devices. I am unable to resolve the issue in spite of all suggested and
other logical steps.

 

Wifi very slow on laptop compared to other devices

Hi Raghu, thanks for your question. I'm Graeme, a Microsoft Community expert and fellow user.

Do you know if your laptop's download speed improves if you plug an ethernet cable into your laptop from the router?

You could try reinstalling your WiFi adapter's drivers. Here are the steps:

- Press Windows Key+X and choose Device Manager.

- Find your WiFi adapter in the list.

- Right-click it and choose Update Driver.

- If that doesn't work, try uninstalling it and then scan for hardware changes to reinstall the driver.

Or you could see what the troubleshooter does. Click Start and type "troubleshoot" then select the first result. Scroll down and choose Internet Connection. Run the troubleshooter and it may help.

Otherwise, let me know what brand and model you laptop is and I'll find the correct drivers for your WiFi adapter to download manually.

Please let me know how you go! Thanks!

 

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.
