D-Link's usually have a netmask of 255.255.255.0 -- and an IP of 
192.168.0.1, and since your linux boxes are 192.168.1.x, they are outside of 
the netmask range and the dlink ignores them.

Set the LAN netmask on the dlink to 255.255.0.0, or change it's IP to 
192.168.1.1, or change your linux boxes to 192.168.0.x..

Also, the dlinks default to have a DHCP server running on them -- so you 
could set your linux boxes to use DHCP to autoconfigure an IP, but then you 
wouldn't always know what IP they would be. (They would probably start at 
around 192.168.0.100 or so.)(To try dhcp, just type dhcpcd and press enter 
and wait. dhcpcd stands for "Dynamic Host Configuration Protocol Client 
Daemon. dhcpcd requests to be assigned an IP, netmask, default gateway, and 
DNS from the dlink.)

After changing the IP or netmask as above, just set your default route to be 
192.168.0.1 (or whatever you set the LAN ip to on the dlink.)

I don't know what distro you use, so I don't know which network 
configuration utility you would use, but to test it, you could type these on 
one of the linux boxes:

ifconfig eth0 192.168.0.2 netmask 255.255.0.0
route add default gw 192.168.0.1

Of course you might type route -n (then press the ENTER key) to make sure 
there isn't already a default route.

You'll also need to set up a DNS server IP. You can use whatever network 
configuration tool you have or like, or you may be able to just edit 
/etc/resolv.conf and add the line:
nameserver 192.168.0.1

before any other 'nameserver' lines.

Hope this helps.
