Overview

---

For Windows devices, the Winsock reset command restarts the communication required between your device and the network. The int ip reset command rewrites the rules, resetting it to factory default, that are followed by devices to connect to the internet.

For Apple devices, removing the preference lists (plist) resets the network settings. Removal of the certificate and the password ensures that the device does not automatically fill in the wrong information when reconnecting to the network.
