Lost Internet

[BagelAnne]

Please help.
I seem to have lost the internet. I contacted my isp support and was escalated to a higher level techician 4 times with no resolution.
Through troubleshooting we got to the fact that we can ping ip addresses but not names.
I gave googled this but have not found a solution and do not really understand a lot of what they were suggesting.
Can someone help?

did they come to the conclusion that the problem was on your end or theirs

How is your system set up , are you connected to a router or directly to the modem
Are you using cable, dsl or dialup

[BagelAnne]

They concluded that it was a dns problem on my computer.
I get on the internet by wireless router but I connected directly to the cable modem during the trougleshooting

They concluded that it was a dns problem on my computer.

Try to flush your DNS
open command prompt: start - run - type cmd - hit enter
type ipconfig/flushdns - hit enter

[BagelAnne]

I am so glad you are there!
I performed the flush yesterday and again today.
Still cannot get on the internet.
Also tried netstat and get Messages received 1, messages sent 13, destination reachable received 0, deatination unreachable sent 12

Try "nslookup www.microsoft.com" and post results.

Also noticing that every time I go to shut down, it seems to want to install 2 windows updates.
I have shut down at least 8 times and it is still wanting me to wait for the installation of 2 updates.
Relevent?

[jconstan]

Lets try this.

Power off the modem, router and pc.

Then power on the cable modem and wait 30 seconds.
Power on the router and wait another 30 seconds.
Then power on your computer....anything change?

Do you know how to get into the router? What kind and model is it?

[BagelAnne]

I had called my ISP and they had me do just what you suggested. They also reset the cable modem from their end.
Nothing worked

[buggabear]

Have you tried another computer to see if the problem is on the isp's end or in your computer.

[BagelAnne]

The computer I am on now is sitting next to the problem computer and both are using the same wireless network.
The problem computer worked until 2 days ago.

OK that narrows it down the problem is in your computer not the isp.
Try something simple first before the experts come with the hard stuff.
Have you done a system restore.
Go back 2 weeks and once it comes back up see if it connects

[BagelAnne]

I did a system restore. I went back to February 12

[BagelAnne]

I have been following the troubleshooting methods I found on
»www.zdnet.com.au/insight/soa/How···1,00.htm
Using nslookup, I got to the conclusion that the DNS server is functioning properly and the domain is properly registered on the internet, but none of the naming servers are operational.
Now, I need to determine whether the problem is with the DNS server or with the root registration.
This is where I an stumped.

Hello,

I've one thing you can try - if you haven't already - that has resolved some sticky internet connection problems for me; at least for hardwired connections . . . you stated the computer you are having problems with is capable of both.

Determine what make/model of network interface you have - be it on-board or an add-on card - and make sure you have the drivers on hand for it . . . though if using XP (or Vista, but unsure) you probably won't need them . . . but I'm not sure about the drivers for the wireless functions.

Go into device manager, and uninstall the network interface listed. Reboot. Windows will find your "new" hardware and install the drivers for your network adapter.

I have no idea what causes it, but sometimes a network adapter gets, well, "locked" I call it . . . it refuses any kind of input from a DNS server, or anything else for that matter. I've had it happen twice - well, at least I've had two incidents of connection problems that were solved by this method - and simply removing and reinstalling drivers didn't work . . . I had to actually "uninstall" the adapter via the device manager.

Hope this is of some assistance.

Thanks for the reply.
Thanks for the suggestion.
I actually swapped out the wireless adapter with one I know works and that did not resolve the name resolution issue.
Any other ideas are more than welcome.
Nothing I have tried is working.

[BagelAnne]

want to thank everyone for your help.
I am especially grateful to BuggaBear for all the time he spent with me in researching this problem
I finally decided to try a repair install of windows xp and that seems to have fixed the problem.
