Ok, so you have it connected through the WAN port to your internal LAN. 
Did you try specifying the subnet mask on the route you put into your
server?  You need to get a route on the server otherwise when you try to
talk to any device on the 192.168.2.0/24 subnet your packets are getting
routed to the Internet connection which not what you want.

Try specifying your route add command as 


route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.7

Someway you need to get this route into your servers routing table.
Are you getting an error when you run this?  If not provide a netstat
-rn when you have added this route.

If that does not work then I think you should try just using the
bridging function of the linksys.

To do that disconnect the cable to the WAN port on the linksys and plug
it into one of the switch ports.  Reconfigure the LAN to use 192.168.1.7
or some other IP address on your LAN.  Would be best if you used an
address outside the DHCP range being used on your LAN segment.  You will
need to find out the range being handled by the DHCP service.

Disable DHCP on the linksys and let the other device on your LAN that
passes out DHCP addresses do that for your wireless users.

In this mode all devices including your wireless users will be on the
192.168.1 network.  The linksys will just act as a bridge.
