Unhappy How do I setup my router?
I need HELP, Iíve had cox ISP and recently moved and have Cavalier ISP now, the problem Iím having is that I can connect fine wired to my desktop or notebook but not wireless to any notebook also I canít connect my Xbox, Vonage or Ooma devices wired from the router or even directly from the modem. Error message when I bypass the router and connect the Xbox direct to the Cavalier 6381-A4 modem: ďCanít obtain IP address from your modemĒ
Iím using a Linksys WRT310N Router
Cavalier 6381-A4 Bridge/Router Modem

DO Cavalier ISP allow multiple PCs to connect - they may register the first MAC address and then thats all that is allowed on the PC

So both machines will work fine via cable

how many notebooks do you have?

What is the status of the
The wireless LED

Wireless (Blue) The Wireless LED lights up
when the wireless feature is enabled. If the LED
is flashing, the Router is actively sending or
receiving data over the network.

Let's see this when connected directly to the Cavalier 6381-A4.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

There's a good reason for the problem. Your "modem" is a modem/router, and it's using the same base subnet as the Linksys. Here's an alternate configuration for the Linksys that will solve that problem and eliminate the extra NAT layer that may also give you problems with some applications.


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
