I have more fundamental problem to that which started this thread, in that I can't get the Arduino to respond (running ChatServer) to another device on the network via Telnet. No matter what I do I simply get the Connection refused statement. I can't work out whether this is Arduino related or router related.
What I have established is telnet works on my system (OSX10.9), it's connected via wireless, the Arduino has adopted an IP address and I can ping this IP. How do I establish the cause for the non-connection i.e. it is because I have router restriction (I don't believe I have but I'm not ruling it out) or is it in somewhat related to the firmware issues which started this thread?
Any pointers/suggestions please?
