The HDHR (at least this model) doesn't support static IPs. I'm setting
it based on MAC address with my router's DHCP server (a Linksys
WRT1900ACS running dd-wrt). Note that it was totally dropping the link
itself, which doesn't sound like a DHCP issue. When it keeps the link
it gets it's IP with no problem.

Thanks!
