Hi Lee
After the first format ( using version 5.0.1) and loading of the latest software it took quite a while before it started scrolling through a list but stopped and hung then came up with a message disk corrupt use scandisk , so I Scandisked the sd card and tried again this time it scrolled through quicker and finished at the paw login, I then turned it off and inserted the wifi dongle the screen came up with the rainbow then after a couple of seconds scrolled through to the paw login, but still no wifi, turned it off to change the wifi dongle,that's when I found the dongle was hot and had melted the red plastic.
Stripped unit from it's case checked for any obvious signs of burning, found none. Then leaving unit out of it's case put the new wifi dongle and my old gps dongle in and powered up, ran through the scrolling screen and it stopped at paw login.
Still no wifi, temperature of the board was ok no hot spots, the gps dongle started flashing green.
I have now ordered another wifi dongle , will give it one last try when that arrives next week.
Thanks to you and Peter for your time and patience.
