I have a wireless router (HDStream Gigabit Dual Band Wireless N Router - 600 Mbps - w/ USB Server) that I need to connect to a Cisco Switch in the server room. the wireless router will be downstairs and will be used to connect to one, possibly 2 computers wirelessly and also setup a Guest account so that the guest in the restaurant can have free WiFi. The one or two computers need to be able to connect to the LAN so that it can access the servers which are upstairs.

Right now I have the wireless router set up in my office so I can configure it (which I am new to doing that). but will go downstairs once it is configured to do what I need it to do. My computer is directly connected into one of the Ethernet ports on the wireless router and a cable from the switch is connected into the LAN port. I noticed that my IP address is a 192.168.X.X address. How do I get my PC (and eventually the one or 2 computers ) have the IP address of our LAN (10.10.X.X).

I am not at office, so I can not try this until I get back there on Tuesday, however I was thinking, would it be possible for me to instead of having the cable from the Cisco Switch going into the LAN port on the Wireless router just plug it into one of the Ethernet ports? Will that work? if not, what do I need to do to accomplish my task?

Task:
connect 1 or 2 computers to a wireless router with our LAN IP address (10.10.X.X) and not of the wireless router (192.168.X.X).
Setup up the wireless router for Free Guest WiFi access and not have access to our Network.

thanks in advance for any suggestions!

That router is almost impossible to find any support information on so I will assume it works like almost every other consumer router.

If you just wanted to run this on your network and have it use the LAN addresses of the main network then yes all you do is connect it to the LAN port and disable the DHCP. Disable DHCP is critical in a corporate network you can causes massive issues if you leave a second DHCP server active.

If that is all you wanted you would be set since this is the standard run your router as a AP trick.

The guest wireless is a huge addition. The guest wireless on most routers is design to protect the lan and main wireless from the guest users. This works ok when the router is directly connected to the internet on the wan port the router can prevent the traffic from coming back. If you were to hook this to your company network the guest would be on your network. Besides when you run as a AP you lose this feature in most consumer devices because this is a part of the router function and you are not using it.

The way you accomplish this is by running multiple vlans. You would need a device that can run as AP and assign guest to a different vlan as the ports on the main network. It then must use what is called vlan tagging to keep these vlans separate over the cable to your cisco switch. And still you are not done. Your cisco switch must now also keep these vlans separate all the way back to a another router that can allow access to the internet. It is this router that will be responsible for keeping the traffic separate and assigning IP to the guest vlan.

Of course commercial AP all have this ability but you can run things like dd-wrt on consumer routers to get the feature also.
