it´s gargoyle-router (openwrt with webinterface)

Yes, I´m just lacking of a pc with a serial port :) (but will try to manage to find one)

I think, the problem isn´t related with voyage itself. Maybe it´s because the board (alix 2d2) initialize it´s usb ports so late. I experience something similar with the external harddisk. Specifying the drive in fstab isn´t enought to mount it at boot, running a script after bootup with "mount -a" works.
I removed wlan0 from /etc/network/interfaces and added to the post-boot script

sleep 10s
ifconfig wlan0 up
iwconfig ....
wpa_supplicant...
dhcpcd ...

These commands connect to the wireless if I am connected through eth0.
Still, establishing an automatic connect at boot to the wireless only works, if a wired cable is plugged in. Surprisingly the cable doesn´t need to be plugged to the router, it can be even plugged into another (turned on) notebook, without having a dhcp server installed on the notebook. Are there some special scripts started, if there is a cable plugged in the wired port?

For the moment it´s at least working like this (connecting a cable during boot), I´ll try to find a pc with a serial connection within the next days.

regards,
Thomas
