D-Link 655, the router I recently installed, is a router only, so I have to use a separate modem.
The problem is that I can access the router configuration pages only, but there is no way I can access the modem config pages.
The only way is to disconnect modem and connect it to the computer NIC directly.
I don’t know if I set IP for each device correctly, but I read somewhere that router and modem must have a different submask, so:
Modem IP: 192.168.x.1
Router IP: 192.168.y.1
(IPs are not the ones I’m using, it is only an example).
With these settings, the computer NIC must be 192.168.y.2, i.e. it must have the same submask of the router.
But because of modem and NIC have different submasks, I can’t access to the modem config pages.
There is a way to solve this or I have to disconnect modem, change NIC IP and connect the modem directly to the PC?
