Thank you Alastair, yes I panicked. I'm about to go out so will come back later.
1. I have not used the Config tool - I use SmartPSS. My Mac doesn't allow Config Tool because it says it's not authorized (Should I just override that?)
2. I assume because I couldn't access it using my usual IP address - I will check again later
Alastair, you know how
Wiki says to reset the device after firmware upgrade - do I press Factory Default or just Default - to reset (under System > Default)
Thanks, and apologies, I appreciate the pointer.
