Exclamation DNS Issues. Please help!
Please Help! When I plug my desktop into my wireless router I have slow internet but when I plug directly into the modem I have no connection at all. It says "cannot connect to primary DNS server". I'm using a Motorla SURBOARD SB6121 and a NETGEAR WPN824V2 Wireless Router. When I do ipconig /all this is what I get:

Any ideas on how to fix this. It's quite irritating. Thanks!

What is 10.0.0.1?

Try setting it to automatic. But keep track of the current settings in case you want to go back.

Ipconfig is the same even with automatic gateway and IP assignment?

Why do you think it is a DNS problem?

Can you get to sites without using DNS?

I went into "network and sharing center" and "properties" under Local Area Connection and made sure under TCP/IPv4 that Obtain IP Address Automatically was selected as was Obtain DNS server Automatically was selected. They both are. This is what I get now with Ipconfig /all:

It's the same as the manual settings. How about whether you can connect to a site without using DNS?

your pb NOT with your laptop or your router ... the internet provider server cant give you IP adress , i suggest you 2 steps :
1- Reconfigure /reset/ your router and try it after installing your user name + password
2- if this not work then all what you have to do is calling your ISP .

Is the IPCONFIG /ALL from a connection to the router?
If that is a router connection, what do you get connected directly to the modem?

With the computer connected to the router and a working connection from the router to the modem, what is listed on the Router Status page for the Internet Port.

MAC address
IP address
DHCP
Subnetmask
Domain Nane Server

That DNS message can be a generic message.

When connected to the router can you click on these links and tell us which one works:

http://www.google.com -- http://74.125.227.130

If the second one works but not the first one, then you indeed will have a DNS issue.

As dlsayremn mentioned, if you go direct to the modem instead of the router, do you get the same results with those links? If so, then in Command Prompt, type cls then press enter first, then type in nslookup google.com and press enter. Then right click on the black screen, choose select all, press enter then paste the results here.

You can also try adding a DNS server manually like google 8.8.8.8 or Open DNS 208.67.220.220
