1 cable modem with 1 router and 1 wireless router...possible?

bentz69 · 03-01-2009, 01:49 AM

Heres the situation. I am renting an apartment in someones home. They have provided me with an ethernet cable from their router(not wireless) but the line is located in a different part of the room that i want my computer to be located in. I CANNOT snake the wire under the carpet or along the wall and do not want a line running through my living room.

So basically there is a cable modem in one section of the house with a conventional router attached to it. That router supplies me with a ethernet cable. I would like to put a wireless router on the cable that I have so I can use my computer in a different location. Will this work?

Yes but you will most likely have to turn the DCHP function in the router off.

in both routers?

No the wireless one you add because the DCHP resides elsewhere on the network you're basically making it a wireless air point.

this is all new to me so forgive my ignorance

No you'll have to buy a wireless router the configuration changes would be made in the router set up not your computer, does your computer have a wireless card now?

Bite the bullet and just run some cat5 cable, I couldn't believe the increase in download speeds I got. I bought 150 ft cable for like 35 w/shipping online, and ran it from downstairs where our modem is. Anyways, if you're going to get a wireless router you would have that act as your main router and the second one(non-wireless) act as a switch. You can usually make a router act as a switch. If you get a wireless router, have that be your #1 router, and the other be a switch. Disable the DHCP in the switch/router #2 as it will get it from #1 router. Also, set #2 router to a different IP. I don't know the specifics, but from what I've learned it goes something along thouse ligns. I'm sure someone else know exactly how to do this.

Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

For reference, here's a link to a Typical example config using a Netgear router
