WRT350N can't see internet

Question

I may have bought the wrong product.  The box and online info said it included a WAP and I wanted to be able to attach storage as well.  I'll give detailed info so hopefully someone can get me straightened out.
I'm running a Windows Small Business Server 2003 SP2 network at home.  The server connects to the internet via one NIC through HughesNet and to the rest of my wired network via another.  All client computer internet traffic is routed through the server.  Each user (wife and kids) has their own storage space on a RAID in the server that is mapped to reconnect when they log on from any client.
Using the default settings on the WRT350N gets me access to the internet from the clients, but the mapped drives won't reconnect.  First online support tech wanted to change the router IP after disabling NAT in the Advanced Routing tab.  After disabling it I lost all connectivity and the chat session.  Reset the router and tried again.
Second chat session was done from a client PC connected to the wired network with another connected through the WRT350N so I wouldn't lose connection with the chat.  This time I was asked to change the router IP and disable DHCP.  After the changes I was told to reboot the router and my server.  So much for a stable chat connection.
Current network configuration is as follows:
HughesNet appliance has a default IP of 192.168.0.1.  It is connected to the server and has assigned 192.168.0.8 to the NIC.  The server connects to the rest of the network through the second NIC to a multi-port switch.  The server has assigned this NIC 192.168.16.2.  Addresses from 192.168.16.0 to 192.168.16.9 are reserved by the server.  Clients are assigned 192.168.16.10 to 192.168.16.254 by the server's DHCP.  I have  3 UPS, 2 CD servers and a PDU assigned static IP addresses between 192.168.16.91 and 192.168.16.99.  The WRT350N now has a static of 192.168.16.10. 
With the latest settings I still can't get to the mapped drives either by the assigned letters or by typing the full URL for the server space.  From a wireless PC, typing 192.168.16.2 takes me to the server's main page, and 192.168.0.1 gets me to the HughesNet appliance's status page, so I'm getting to and through the server and to the appliance.  Any attempt to connect to a web site returns an error saying I'm not connected to the internet.  I can see other computers connected to the wired ports on the WRT305N and the router itself.  I can also access the router at 192.168.1.1.  From a PC connected to the wired ports of the router, when I try to access anything other than the router's setup page, I get the not connected error.  Using Windows Explorer to look at the entire network, I see the wired and wireless PC in my internal domain, and the router in another network identified as MSHOME.
Any direction would be greatly appreciated.

Update-
After looking at posts for other devices, I moved the connection to my wired LAN from the Internet port on the router to one of the LAN ports.  I don't know if this is the correct fix or just a patch, but it seems to work.  I'd still like to hear from someone with better technical knowledge to make sure I'm doing the right thing.
