Troubleshooting Procedures

  • Making a backup: The easiest way is to use the LuCI web GUI that archives the entire /etc directory. You can also use sysupgrade -b backup.tar.gz to save the important files.
  • Discover the link-local IPv6 address for your router.
    1. Connect your computer to the router using Ethernet.
    2. Determine the name of your computer's Ethernet interface (not the router's). It will be something like eth0, en0, etc.
    3. Use ping6 to the IPv6 link-local multicast address to get responses from all devices on that link. You will see responses like this (computer's interface was en0):
      ping6 -I en0 ff02::1
      	
      PING6(56=40+8+8 bytes) fe80::aebc:32ff:fe8e:d769%en0 --> ff02::1
      16 bytes from fe80::32b5:c2ff:fe84:d35e%en0, icmp_seq=0 hlim=64 time=3.662 ms
      ^C
    4. Now you can SSH in using the link-local address found above:
      ssh root@fe80::32b5:c2ff:fe84:d35e%en0
  • Enter Failsafe mode. If your router seems uncommunicative after making a change, you can usually reboot into failsafe mode to log back in.
  • opkg errors: As of July 2016, LEDE is evolving quickly. If opkg install gives errors, it is likely that the current package builds do not match the firmware image you installed. Get the current firmware image, reinstall it, and retry the steps above.
  • getstats.sh a script that collects a known set of statistics and log information into a single file for easy review
