Unable to set a static DNS server ip address. Keeps returning "...invalid primary DNS address", same for secondary. I'm sure I'm following the manual, I've used several different and known good addresses. The device seems to be hard coded in the whole static IP address as well as static DNS. It will only let me use 209:18:47:63 and 209:18:47:62. And this also with the cable coax unplugged, no ISP connedction. TNX
