Freifunk Monitor

What to do if Freifunk appears to be down

Log on

  1. Connect the C.H.I.P. via USB to a Mac and execute screen /dev/tty.usbmodem*. It will bring up a serial console (via USB).
  2. Log on (you may have to press Enter before that, so that the login prompt appears). Default username and password are chip.
  3. When done, exit screen with Control-a, Control-d (where Control-a is screen's prefix).

Check the WiFi connection

The C.H.I.P. is connected to the Freifunk network via WiFi. Use nmcli to check and, if necessary restart, the networking on the chip:

  • nmcli n connectivity should report full.
  • If it is none, restart the network with sudo sh -c "nmcli n off; nmcli n on"

Optionally, check the IP address assigned with ip address show wlan0.

  1. sudo TERM=linux nmtui
  2. Select "Activate a connection" adnd then "Freifunk".
  3. If that doesn't help, unplug the Freifunk router's power cable to make it reboot.
