Hello all,
I'm sure this will exasperate some, but I'm at my wits end.
Hardware:
Arduino Mega2560
Arduino Ethernet Shield
Actiontec MI424WR from Verizon
I've loaded the DhcpAddressPrinter sketch on to the Arduino and I consistently get Failed to connect to DHCP server. I have factory reset the router and tried again to no avail.
My main goal is to set up Teleduino on the Arduino. When I use the Ethernet sketch from Teleduino the Arduino never connects...never shows up in my router's list of connected devices.
I've also set DHCP to false inside the Teleduino sketch and added my router configuration, making sure to pick an IP outside the DHCP in concurrence with setting up a static IP with the router using the same MAC address and IP as is in my Sketch....to no avail.
Either the router hates me...the Ethernet shield or I'm an idiot. I'm willing to accept any or all at this point.
Any help figuring this out is appreciated!
