+Check which groups you are in, and which are available:

+cat /etc/group
+groups
+cat /etc/group | grep $USER

+Remove yourself from all groups, and add yourself back to only `wheel`, `audio`, and your own group:
+
+```sh
+sudo usermod --groups wheel,audio,$USER
+```

+Add yourself to the `wheel` group:

+Add yourself to the `network` group:

+
+The changes will not take effect until you log in again, so reboot or log into `localhost` with [ssh](../networking/ssh.md).
