Hi,
Well I tried using a different location and thus a different router and the strangeness continued.
When I left home the Yun was allowing me log on to its AP mode, but still giving me a 'bad gateway' when I tried to access 192.168.240.1.
When I arrived at my mothers I tried it again. I was able to log on to the AP directly from my laptop, and I got the web panel access, but it was still messed up with the password. I then tried another reset-to-factory-anyway thinking I was on a roll, and then was back to it behaving as a AP and 'bad gateway' when I tried to access the web panel.
I then ran the Yunseialterminal sketch and accessed failsafe mode I noticed that the command prompt for the command line was 'root@(none)' and not 'root@Arduino' as someone has suggested it might be.
Also right now I am loosing confidence in the procedure for resetting the Arduino back to factory.
If I log on the the Yun in AP mode and examine the connection status I noticed that the IP address is listed as 192.168.240.168.
If try the web panel I get 'bad gateway'. If I leave thing along for long enough the IDE port selection finds the Yun and lists it as '7thYun 192.168.240.1'. Now the interesting thing being I called the Yun 7thYun as it identifier when I did have access to the web panel. If I was able to truly reset the Yun then that should have disappeared.
So that makes me think I am not even able to reset the Yun correctly even is I go in to fail safe mode and enter 'reset-to-factory-anyway' I have read a few texts about how to execute that command and one of them says simply enter safe mode and enter 'reset-to-factory-anyway' and another says: enter fail safe mode, enter 'cd /user/bin' and enter './reset-to-factory-anyway'.
Which one is right I am not sure any more and I doubt either is working.
I have taken a copy of the text on the Yun serial terminal and hope to attach it to the bottom of this message in case it helps:-
At the moment I am thinking that the Yun is messed up in a way I can not understand and will start researching how to re install the whole operating system on the Yun
Any thoughts will be appreciated.
Regards
Liam
