help needed with DNS server not responding

Hello all,

I have a Linksys WRT150N router and a cable modem. I've had this setting working perfect until couple of days ago. My cable company gave me a brand new modem ro replace the old one, ever since I've made the switch, I can  not use my wireless anymore. It detects the network, but it does not allow me to surf the net. When I troubleshoot, it gives me an error message 'DNS server not responding'. I've called my cable company and they say it is problem with the router not getting the DNS correctly. They got me online via ethernet cable but can't do anything about the router. We changed the DNS settings to connect to a local server here for the LAN, but after that I have no idea what to do. I've tried resetting router and modem several times. If anyone has any ideas what to do, please help! Thanks all! Here's my ipconfig/all.

Re: help needed with DNS server not responding

It's also giving me the following when troubleshoot:

'windows can't communicate with the device or resource (primary DNS server)'

Re: help needed with DNS server not responding

On the router setup page,assign the static DNS 8.8.8.8 and 8.8.4.4 and save settings..

Re: help needed with DNS server not responding

How is all that connected? You have a public IP address on the ethernet card and the IP address from the WRT on the wireless. Of course, if your computer is directly connected to the modem and has an internet connection the WRT won't be able to connect to the internet. Your ISP only lets you have a single active internet connection at any given time.

Make sure the wiring is correct: the internet port of the WRT connects to the modem. No other computer is connected directly to the modem (through ethernet or USB).

Wire the computer to one of the LAN ports. Open the web interface of the router at http://192.168.1.1/ Make sure the router is configured for Automatic/DHCP on the internet connection. Then check the Status page. If the router does not get a public IP address from your ISP use the MAC address clone function on the main Setup tab. Clone the MAC address of the computer which had internet before directly on the modem (if it's still the computer with that ipconfig /all info then it's 00-26-B9-0F-D2-89). Save it and check the Status page again. You should now get an IP address from your ISP.

Re: help needed with DNS server not responding

Thanks. I will try that. I do have my cable modem going to the router and from the router there's one desktop connected w ethernet. My laptop was always wireless. There are no computers conncted directly to the modem itself. I know I have the wiring right.

Re: help needed with DNS server not responding

Well, the ipconfig output you have posted tells you that the computer has a public IP address on the wired ethernet connection which means it is somehow directly connected to the modem, either because it was plugged in there or because the router is dead (blinking power light) and the unconfigured switch connects all 5 ethernet ports.
