Thread: Internet Connectivity Issues

I was hoping one of you might be able to help.

Signus' computer suddenly went offline tonight. One minute it was connected to the Internet fine, the next it was gone. He is running Windows 7 Ultimate 64 bit edition. This is a wired connection.

Here are the errors he is getting:

• windows can't communicate with the device or resource (primary DNS server)
• Your computer appears to be correctly configured, but the device or resource (www.microsoft.com) is not responding.
• The DNS server isn't responding

This isn't a configuration issues with Windows because no other computers in his house can get online either. And like I said, he was online one minute and then off the next.

Does anyone have any insight that could help? I'd be incredibly grateful.

What type of internet connection is it? DSL, Cable, satellite, ..?

The first thing you should always try is restarting your modem and/or router.

Yes, tried that. Also tried restarting the computer. Obviously, that was fruitless since none of the computers in his house are able to get online.

It's a DSL connection.

What he said.

Beyond that, troubleshooting is usually pretty easy. The only time it becomes difficult is if you have to authenticate (PPPoE or similar) with a username and password configured on the router. 99% of people forget these credentials and then end up having to call their provider for them.

There are plenty of self explanatory status lights on modern routers and modems. You obviously want to see Internet or WAN illuminated. I think the old school DSL modems have a Sync light that needs to be illuminated.

Hey JJ im not sure if this helps in any way but this happens a lot to me,One minute im on the internet fine the next cut off.The last time it happened to me it came up with the same DNS error,after a lengthy discussion with my ISP they told me my modem was faulty and i needed a new one if all the computers in signus's house are ran of one modem mabe the problem is with his modem.I also had this problem when my ISP was down in my area im not sure what its like in OZ but here it can be pretty unstable here mabe its worth him havein a chat with them?
sorry if this dosn't help in any way just wanted to say ive seen these errors on my computer before and this is what i did BK
