Freifunk is 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)
3. When done, exit with Control-a, Control-d (where Control-a is the 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.
