I just want to make sure if I use it, I don’t mess up the internet for other people on my wifi. Thank you.

Hi there.
The network lock function is used to prevent your real IP or DNS from been revealed if for any reason your connection through Air VPN’s encrypted tunnel gets dropped.

It works by forcing all your traffic through the tunnel and onto Airs servers. When you activate the lock no other traffic will reach the Internet

There’s no danger of you borking your WiFi or connection, as soon as you deactivate the Network lock you will be able to access the Internet.

This feature is one of the stand out uses of Airs VPN client.

You can always ask at Airs forums for advice.

EDIT: Using this feature will only affect the machine that the client is run on.
