I just upgraded to the latest firmware on both my CS18AI and my RM32AI. After the update, I can only get them to talk via wireless connections. WIth a direct cable between the two I see link lights on both devices but no IP pulls on the CS18 like it used to. I see the screen is a bit different so maybe I am missing something simple but so far can not get it to work. Wireless dongles work great connecting to my network.
