Ok so I am having an issue My SSID on my wireless has a space in it and I have tried modify the /mnt/udisk/system.cfg with an escape character WIFI_SSID="xx\ xxxxxxx" but I still getting Error: invalid extra argument 'Wireless'. Any help would be appreciated this work on the raspberry pis no issue even with no escape character.

So it seems your script /etc/wifi_config.sh that is parsing /mnt/udisk/system.cfg is not taking into account a space in the SSID which is a huge issue as I do not feel like changing 75 device to make the CB1 work. I could create a separate network but that defeat the purpose of a guest network.

Read /etc/wifi_config.sh and inspect how it parses WIFI_SSID from /mnt/udisk/system.cfg. Test the configuration with an SSID containing a space, such as the reported "xx xxxxxxx" value. Done means the script accepts the SSID without reporting an invalid extra argument and can configure the wireless network.
