I have a small office LAN, windows 2003 SB server running a domain, 4 workstations attached via a 8-port switch.  There is a stand-alone workstation that had internet access via a westell DSL modem.  The customer had purchased a linksys wireless kit (wireless router & wireless USB NIC) in hopes of allowing one of the wired workstations to have internet access.  I installed the wireless router at the stand-alone PC, configured the westell to bridged mode and attached to router, connected the stand-alone PC to the linksys router (4-port wired and wireless) via wired connection.  The problem I'm having is with the networked PC.  My thoughts is this setup would be like a bridge only without the actual bridge (they don't want the rest of the domain to have internet access).  On the networked PC, with both connection active, I can access the server but not the internet, if I kill the wired connection I can then access the internet via the wireless connection.  I have tried both connections on a 192.168.1.x segment and with the wired on a 192.168.1.x and the wireless on a 192.168.2.x, doesn't make any differrence.

What am I missing?  Thanks in advance.

It should work.  But you may need to screw with the routing table.

With two interfaces, the issue on the networked PC is where do I send packets to?  That's what the routing table does:

C:\Documents and Settings\Burton>route print
===========================================================================
Interface List
0x1 ........................... MS TCP Loopback interface
0x10003 ...00 80 c8 93 05 77 ...... Intel 21143-Based PCI Fast Ethernet Adapter
(Generic) #2 - Deterministic Network Enhancer Miniport
===========================================================================
===========================================================================
Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric
          0.0.0.0          0.0.0.0    192.168.142.1  192.168.142.100      30
        127.0.0.0        255.0.0.0        127.0.0.1       127.0.0.1       1
    192.168.142.0    255.255.255.0  192.168.142.100  192.168.142.100      30
  192.168.142.100  255.255.255.255        127.0.0.1       127.0.0.1       30
  192.168.142.255  255.255.255.255  192.168.142.100  192.168.142.100      30
        224.0.0.0        240.0.0.0  192.168.142.100  192.168.142.100      30
  255.255.255.255  255.255.255.255  192.168.142.100  192.168.142.100      1
Default Gateway:     192.168.142.1
===========================================================================
Persistent Routes:
  None


See that default gateway?  That is where to send anything that doesn't match.  What you need is for the table to tell the networked PC to route local stuff out the server side interface and everything else out the other one.

Post your route print output and I'll help you with the proper command.
