I have a "small" problem with my Yun and after searching the forum I couldn't find something similar. The problem is at follows.
I have a Yun and I moved the root to SD following this link http://arduino.cc/en/Tutorial/ExpandingYunDiskSpace All went fine or at least looked like. The Yun acts as an access point and bridges the wan (on eth1) with lan (on wifi). Untill this point works perfect. I can connect to the wifi of yun and have access to the internet like on a regular router AP. Now comes the "funky" part. If I disconnect the Yun, or reboot it, it returns to the standard SSID (ArduinoYun and no password for wifi) but it keeps the new name of the device and the password for webinterface, also keeps in memory the bridge thing becoming a free wifi hotspot for my neighbors.
What can I do to keep the SSID and password after I reboot or disconnect the yun? It is annoying to have to set up every morning the SSID and password.
Here I found only the file for the default SSID https://github.com/arduino/openwrt-packages-yun/blob/master/arduino/yun-scripts/files/etc/init.d/rename-wifi-if-access-point#L12 but does not help me too much to hard-code the new SSID as long as is still have to setup the password.
Has to do with this file? https://github.com/arduino/openwrt-packages-yun/blob/master/arduino/yun-scripts/files/usr/bin/wifi-reset-and-reboot If yes, where should I put the key and the encryption? - I don't know too much about linux commands, I am in learning process.
Thank you for your answers, Christian
