Wi-fi connection issue

Posted by John Liu on Tuesday, December 21, 2021

When playing with Hyper-v, I somehow managed to break my local Wi-fi connection. The issue was that download speed is normal whereas upload speed is very slow (~0.6Mpbs) which caused web browser very slow and sometime error out. I initially thought might be firewall rules (I setup some new firewall rules). After using a physical cable connection, download/upload speed are as normal. Played with update/reinstall Wi-fi NIC driver with no luck. Uninstall device made it worse as it completly broken with error “Windows is still setting up the class configuration for this device”.

To finally fix the issue: Go to Start –> Settings –> Network & Internet, then click on “Network reset” and then restart the computer.
