I thought that I would experiment with the IoT so I dug out a PICDEM.net 2 = demo board. The board will communicate OK when plugged directly into my lap= top but when connected to my Home Hub I can't get a connection; trawling th= rough the User Guide it seems that the issue is that my hub has a built in = web server and the Microchip TCP/IP stack can't handle more than one DHCP s= erver on the network and disables itself. I am a novice to TCP/IP, is there= a simple fix for this and if not is there an alternative TCP/IP stack that= will be more capable? The demo board uses the PIC18F97J60.
