I have had 2 EZB4's connected to my robot for some time now and connecting to them has never been a problem. Tonight, however, I can't connect to the second one. I have one setup in client mode (which connects no problem) and the one I am having problems connecting to has always been in AP mode. I have checked out all the basics to trouble shoot the problems , reset it a couple of times and replaced the EZB with another one which is brand new. Can't connect to it either.

I get this message in the debug window,
8/3/2015 9:49 PM - Disconnected
8/3/2015 9:57 PM - Attempting connection on 192.168.1.1:23
8/3/2015 9:57 PM - Connected to 192.168.1.1:23
8/3/2015 9:57 PM - EZ-B reports EZ-Robot OS v25.5

at EZ_B.EZB.Connect(String hostname, Int32 baudRate)
8/3/2015 9:57 PM - Disconnected

and this window has popped up a couple of times




I have looked at the firmware update video - it seems to be old as I don't have an "update Firmware" in my EZ Builder or do I and I'm not looking in the right place.
I am running the latest version of EZ Builder.

Your help is always appreciated - Thanks

Edit; So now I tried to connect to 4 different EZB's in AP mode and I can't connect to any of them.
