Have tried everything I can think of, and more! It sometimes will present wifiloggersetup as a wifi network name but will stay logged on for a very short time which is insufficient for me to go to the browser and enter
http://192.168.4.1 before it attaches again to my usual home wifi and drops the connection with wifi logger.
I vaguely remember someone talking a long time ago about a crypto key. Anyone heard of this? Might it be relevant?
Please keep suggesting things if they come to mind. I don't really want to buy a new logger if I can help it!
