I am able to ssh into my new RPi. One of the things I like to do to my infrastructure devices is to go ahead and convert their DHCP assignment to a reservation. My router is a CradlePoint
Firmware Version : 2.0.0, 2012/04/16
WiMAX Version : 4.1.645
I added a reservation, revoked it on the router and did a sudo dhclient -r then sudo dhclient and it picked up yet another IP address instead of the one I had reserved - a full reboot seems to have little effect.
I don't have any other trouble with this router and other devices.
