I'm reasonably technical but fairly new to the Edision OS Mini box - also this may be more Vix related so I'm happy to post elsewhere if needed.

The issue I have is that, following several months of having no issues, I found today that the WiFi connection had failed. On further investigation this appears to be due to lack of space on the box. This results in the box crashing each time I edit the wireless settings.

I should be able to connect via FTP on a cable connection in order to remove superfluous files but I'm unsure which files I should look to clear out, and where from.

Can anyone suggest anything? I've included a section of the crash log.
