IEP address

what are you refering to when your asking for a new "iep address"

And what device/devices do you have? 

A better description of your problem might help. 

There's a support site with access to manuals, firmware, install guides, etc.
Go to https://www.netgear.com/support/
Type in your model number and from there it'll take you to the above.
Its a great resource to start with.
