My ISP provides setup instructions for the Internet connection, where among other things it is required to set a specific computer name and a primary DNS suffix. These settings are provided for Windows and they worked as long as I connected my PC directly to the WAN cable. Now I've got a wireless access point (D-Link DI-524) which I would like to place between my PC and the WAN. So I took all the IP settings from the setup manual and entered them into the router configuration. I however have no idea where I should enter the computer name and the primary DNS suffix. I looked through all configuration pages of the device and found nothing similar to these settings. Should I get another router? Or is it even possible to assign a name to a router?
Also, can someone please explain where the computer name and primary DNS suffix fit into the OSI model and why they may be needed?
