Hello.

 

A few days ago we changed from our old modem and router to a new modem and router in one. There are four laptops in the house and since then, all has been well on every laptop except for one. This one laptop can connect to the new network, but is not getting any internet access through the network. The troubleshooter shows the message "Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding".

 

The laptop can gain access to the internet when an Ethernet cable is connected, but is not getting any wireless access at all. It's a 4 year old Dell Studio laptop running a 64 bit Windows 7.

 

I have tried contacting my service provider but their only response was basically to tell me to get a new laptop. Is there no hope at all? Any help you can give me would be much appreciated.

 

 

Here's what ipconfig command gave me:

If it stopped working right after you changed out the router/modem, I'd probably chalk it up to a configuration issue somewhere.

 

Make sure that DNS is also being automatically configured (unless there is a reason it shouldn't be, but usually there isn't).

 

1. Open the "network and sharing center" in the control panel, and then click on "change adapter settings" on the left-hand side of the screen.

2. Right-click "Wireless LAN adapter", and then click "properties".

3. Double-click "Internet Protocol Version 4 (TCP/IP v4)"

4. Check "obtain DNS server addresses automatically" if it is not checked.

5. If you changed the setting in step 4, restart the computer to ensure that it sends/receives another DHCP request/reply.

 

If that doesn't fix it, try reinstalling your wireless driver. While there might not be a problem with the driver itself, reinstalling it usually forces every setting within the driver back to its original state.

The DNS is already being automatically obtained from what I can see. I followed those steps and the box was already checked, though i restarted just in case. (I don't know if this makes a difference, but on this laptop it says "Wireless Network Connection", rather than "Wireless LAN Adapter"). I also reinstalled the wireless driver as you suggested, but the problem still remains.

Do you have any wireless security enabled on the network? If so temporarily disable it and see if the laptop can gain internet access wirelessly.

 

Do the same steps that voodoo suggested but instead of ticking the box to use automatic settings for dns, choose the manual option and enter 208.67.222.222 for the primary and 208.67.220.220 for the secondary. Choose ok then ok again and see if you can surf the web.

I'm not exactly sure what you mean by wireless network security, but there isn't any as far as I know. The computer itself is running Kaspersky Internet Security 2014 with Kaspersky's firewall, but this has been installed for a month with no previous issues. Using those manual DNS numbers did not work for me either.

When I refer to wireless security, I'm talking about do you have to type any password to access the wireless network? Or do you just simply find the name and connect?

Yes it does have a password, but when I access the administration it only lets me change the password, not remove it completely.
