Re: Hurricane damage to office, need static IP

Do you have a DPQ3925 all-in-one static-IP modem, or a any-modem+Cisco 851 router combo?

The latter has the 851 bonded to the modem (by way of configuration) - you cannot move the 851 to a different cable modem.

Please call support to help you - the fact that you're getting a dynamic IP (which is completely unusable for sending mail to world) seems to indicate that the static-IP config on your device has been lost, and needs to be fixed.

Also, you cannot take your static-IP assignment with you from one major service area to another (like NJ to CT, or NJ to LI) - that is not supported, and will not work.
