Windows 10: Extremely slow Wi-Fi on my PC only?

I just recently bought my PC a few days ago and ever since, the Wi-Fi has been terribly slow. I have really good Wi-Fi and I know it is just an issue with my PC because the Wi-Fi works fine on my phone, laptop, and smart T.V. This is also a good P.C. I can't even open google without it taking an hour. Sometimes the Wi-Fi will just randomly disconnect too. I need help. Any suggestions? Thank you.

Slow wi-fi

My laptop, with Windows 10, runs extremely slow on Wi-fi - about 15 Mbps. The warranty dept at Costco is suggesting running Windows 10 back to the factory default. Do you think this will help? I'm thinking it must be a hardware issue, specifically the
network card?

 

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?

 

Slow Wi-Fi after clean install of Windows 10 v1903

I have Intel 9560 Wi-Fi on my ASUS Z390 motherboard and when I do a clean install of Windows 10 v1903 I get very slow Wi-Fi speed at around 1mbps on speedtest.net. I have Xfinity Gigabit Plan with Arris TG3842G modem. Everything is slow until I manually update the Wi-Fi Driver from Windows Update to v21.10.1.2 through Device Manager which downloads very slowly and sometimes aborts and I have to retry because another driver is already installing in the background. After a few retries the Intel 9560 Wi-Fi driver finally installs and the rest of the drivers go much faster. Why is the inbox Wi-Fi driver that comes with Windows 10 extremely slow at only 1mbps download speed with 40bps upload speed at 5Ghz when running speedtest.net? If I disable and re-enable the Wi-Fi adapter in device manager using the original inbox driver I get normal download speed until the next reboot in which the download speed will become extremely slow.
