Windows 10: Internet is extremely slow after Windows 11 WIFI driver update

I'm really frustrated because my internet speeds were fast prior. I installed the driver update , after that the internet is very slow. Speed test gives 10mb now but before it was 150mb. the problem is with only one system where the driver got updated,

Extremely Slow Wifi

Hello!

I have Windows 10 on my PC. I have had a WiFi card in it for over a year now and have not had any problems, yet recently the WiFi has gotten extremely slow. Our WiFi network which can output 450 Mbps is only picking up about 7-25
and that's when nobody else is using the internet. Since the speeds aren't due to the actually connection, you may think its because of the location in the house, and yet when I connect to a speed-test online with my phone in the same location, its getting
150-300 Mbps. I do not believe that the WiFi card is the problem, since I have been using it for over a year and until about two weeks ago, have had no problems with slow internet whatsoever. The only thing that I can recall I started doing about two weeks
ago is regularly installing the windows driver updates, and since then I have been have tons of wireless problems, not just limited to WiFi. Please help!

Thanks,

Andrew

 

Windows 10 - Extremely slow WIFI

Hi Joanne,

It seems that the slow download speed only happens on your wireless devices. Since you've basically performed almost all necessary troubleshooting on both laptops, we would like to ask a few questions to help us further isolate this issue.

• How far is your computer from the router?
• What's the make and model of your router? Is it a single-band or dual-band?
• Are there other devices connected to the WiFi network?

In the meantime, we suggest that you change or specify the channel of your wireless network. If you have access to your router, set it to either Channel 1, 6, or 11, then change the Channel Width to 20 MHz only. Once saved, try checking the download speed again.

Update us on how it goes.

Regards.

 

Internet is slow on certain networks but fast on others

At home, both my laptop and phone are able to access the internet using wifi at a good speed. However, at school, the connection on my laptop is extremely slow. My phone, however, is fine at school (all connections described are over wifi)

So far, i have uninstalled and reinstalled the wifi adaptor driver and updated the driver. Any suggestions are much appreciated!
