Connecting Arris Cable Modem to Westell Wireless Router

[Farrar]

I am fairly intelligent when it comes to networking but I must have a brain fart on this one.

We are on vacation {Panama City Beach, FL} in a condo with a cable modem, Arris SD 3 series. I have brought my Westell 327 W Wireless router / modem from home that I use with my Centurytel DSL account. The IP of the wireless router is 192.168.1.1. DHCP is enabled. My plan is to run the RJ45 cable from the cable modem to the wireless router / modem so both my wife and myself can connect wirelessly. Otherwise, I have to run the 1 Ethernet cable from the cable modem to my laptop. I DID plug the RJ45 to my laptop from the CABLE modem and can connect. And, if I do an IPCONFIG /ALL, I see:

IP address {laptop} 10.202.95.34
Subnet mask 255.255.255.0
DHCP and Default Gateway 10.202.95.1
DNS 10.61.32.1

I know that my Westell router is not on the same network so do I need to change it’s IP addy?

I would like to be able to connect both my laptops wirelessly.

Thanks in Advance,

Sounds like your modem has a built in router. If that is the case, i would recommend logging into the wireless router and disabling the DHCP server. Note the IP address of the router so that you can manualy configure a static IP address to undo this change (or hard reset the router).

Connect the cable modem to an INTERNAL LAN port on the wireless router.

What this should accomplish is turn your wireless router into a wireless access point, the modem will still provide the DHCP and NAT routing, keeping everything very simple. your computer on the wifi will end up getting a 10.202.95.x IP address.

Thank you...that solved the problem and was almost TOO simple.
