Every drop counts

Automate email process

Note: When design Power Automate flow, for file path or folder path values, try not to pick from the dropdown list, but instead type in the actual name. When picking from the dropdown list, the designer will undercover save the actual internal physical ID of the location as well. If you then try to export the package and modify it for a different folder, it will be hard as the physical ID will no longer match with the one for the new location.

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.
