====== Install licenses via USB stick ======

===== How-to =====
  - Router must be in [[faq:install-licenses-via-usb-stick#reset-router-into-factor-reset-state|factory reset state]] (unconfigured)
  - Format an USB-Stick FAT16/32
  - Download the [[faq:install-licenses-via-usb-stick#files|files]] autorun.key and autorun.sh
  - Copy autorun.key and autorun.sh on the stick
  - If you got the licenses in an archive, extract the license files
  - Copy all the license files (00112B*.lic) on the stick
  - Power on the router and wait until it has booted completely. The STAT LED will turn solid green.
  - Plug in the USB stick and the WLAN1 LED will blink slow green.
  - When the installation starts, all LEDs blink green and it takes some time.

Finaly LEDs are 
  * green: ok
  * yellow: ok, but there was no license change, e.g. installed the same license two times
  * red: something went wrong. (WLAN1 blinking: red = no license file, yellow = license file corrupt)
