I've been fighting DHCP issues with Dish DVRs for as long as they've been IP capable. Neither of my 622s or either of my Hoppers will reliably or consistently pull a DHCP address from any of the three servers / routers I've used with them over the years. It's always the same story; a manual reset of the DVR will result in a successful DHCP assignment, but every time the device does it's nightly reboot it doesn't pull an IP address and forcing it to reset the connection via the menu doesn't work either. This means that my DVRs always end up off-line and I can't schedule or view recordings remotely. I'm to the point I'm going to start pulling network traces overnight to see if I can catch the traffic when it reboots but I have to wonder why we don't have the option to set a static IP address and be done with it.
