Wi-fi connection issue

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.

Change NIC category

A network card (NIC) can be classified as in Private network, Public network or Domain network. One can setup different firewall policies for different network category. If need, you can use Powershell script to change NIC netowrk category. #to list NIC network connection profile info Get-NetConnectionProfile #to change NIC network connection profile Set-NetConnectionProfile -Name "Unidentified network" -InterfaceIndex 56 -NetworkCategory Private
