Slow internet using Wifi on desktop

[dustin.huynh11]

The internet on my desktop using the WiFi is very slow. It works perfectly fine using an Ethernet cable, and the internet is fine on my other devices (laptop, other desktop, Ps4, phone, etc). I have ran a speed test on all my devices and the speed I am getting on my desktop is 0.5 mps to 3.0 mps, while on my other devices the speed is around 40 mps. I have tried uninstalling my drivers and resetting my network settings to default, but nothing has worked so far. I have also tried using a wireless USB adapter to see if my WiFi card was broken since it was old, but it was still showing the same speed (0.5 mps to 3.0 mps). I have concluded that this is a hardware problem not a software problem, but I don't know what is causing the problem. I have read on other threads that something called AMD Quick Stream was causing the problem, but unfortunately I do not have that on my computer. I know I should use a wired connection, but I need to get this fixed soon because there will only be WiFi in the place I am going to live in next year.

Windows version?

What wireless adapter are you currently using on your desktop? PCIe as I understand your post.

PCIe card fully seated? Any antenna's or antenna extension cables? All connections properly in place and snug?

Is the wireless adapter correctly configured to match your router. Try "manual" settings if auto. Or "auto" if already manual.

Do you have admin access to the router? If so, check the router's logs for errors if the router has logs and the logs are enabled.

You can also do the following:

Connect up wired and work as normal. Then open Resource Monitor and take a look at the Network tab.

Observe all four categories within the tab.

Get a sense of what all is running and the resources being used.

Then switch over to wireless and again open Resource Monitor and take a look the Network tab.

Wireless may reveal some possible resource issue.
