As mentioned in my first post, webcom/mic monitoring is already off.
I don’t know about unusual network configuration. The SB is frequently docked/undocked which adds/removes the LAN interface. OpenVPN and Ubuntu Bash for Windows are sometimes active, but do not seem to have observable impact when turned off. Nextcloud Client, Directory Opus and Synergy are perhabs less frequently used software with network connectivity. Spotify/Steam/Office but that is hardly unusual.
When working on Ubuntu Bash I sometimes switch firewall mode to “Click to Block”. Thats all I can think of at the moment.
