I seem to have a related issue.
I have two ChumDash's. I have them set up to use a fixed IP address.
The behavior is the same on both: if I unplug the Dash from outlet / power, it goes through the boot process and brings me to the network configuration page.
If I choose " (X) Use an Existing Connection ", / Next / Choose a Network Configuration / (my SSID) / Next / Confirm my settings (which has all correct info re: IP Address) / Next .... Then it tries to "Connecting to Network... " ... and after a relatively long time: "Network Connection has Failed... wlan0 link is down, failed to obtain IP Address, Internet is unreachable".
Does it not support a fixed IP address?
