Enable logging

Modify the Mesh Discovery Sequence

You can put the following values in /etc/NetworkManager/mesh-start

  • school-mpp
  • infra
  • xo-mpp
  • local

These will control where the _mesh_ device starts. Since the mesh device is the first device that gets picked at startup, this affects the immediate connection search of the laptop.

Remember, the current automatic connection cycle is this. You can jump to a specific step in this cycle by putting the string above into mesh-start.

/* Steps:
 *
 * 1. For each channel in [1, 6, 11]:
 *    a. try DHCP
 *    b. if DHCP times out, try next channel
 *    c. if DHCP response includes a non-link-local IP address,
 *      then CONNECTED/DONE
 *
 * 2. Try last successful AP connection
 *    a. if success then CONNECTED/DONE
 *
 * 3. For each channel in [1, 6, 11]
 *    a. try DHCP
 *    b. if DHCP times out, try next channel
 *    c. if DHCP response includes a link-local IP address,
 *      then acquire autoip address and apply DHCP settings (except for
 *      IP address), CONNECTED/DONE
 *
 * 4. Jump to channel 1
 *    a. acquire autoip address, CONNECTED/DONE
