I think I have really bad luck with computers;

Basically, my internet randomly stopped working one day and hasn't since.

It says 'Limited or no Connectivity' and when I repair the connection it says the IP address can not be found.
I am running Windows XP Pro. The D-Link Model No. is DWL-G122. I have tried going My Computer/Properties/Network/D-Link etc and it says the device is working properly.

I don't know what happened or how to fix it :S
Help would be appreciated.

P.S.- I saw a topic almost identical to this but after a while of reading it I got confused ><

SavvyClay,

Have you tried power-resetting your D-Link router? If not, try this and see if you can get on the Internet. If this doesn't help, then try directly connecting your PC (in PLACE of the D-Link router) to your broadband modem. If you can access the Internet at this point, the the problem is likely with your D-Link Router.

If this doesn't make sense - please reply with more detail and we'll be better able to assist you.

I see what you're saying, but remember, it was all working fine until randomly it stopped.

The D-Link little green lights are on, and when I disconnect it, the internet disconnects too.

I am pretty sure the problem lies with the IP address, as I discovered by following another post.


P.S. I accidentally posted this 3 times. How do you delete topics?

SavvyClay,

Have you been able to fix this problem or do you still need help?

If you're still having problems, please go into more detail about your IP address problems.

Are you using Cable Internet or ADSL (i.e. who is your Internet Provider?).

When did your Internet connection via your router STOP working?

If you're still having problems - reply to this post and I might be able to help.

Lets try and see whether you have equipment related problems. In this step, we will allow the equipment to self-diagnose and resolve the problems.

If you suddenly lose connectivity over your High Speed Internet line, have a slow connection or are unable to browse the Internet despite indications that you are connected, it is possible that your modem is not communicating properly with the Internet network.

Save all your current work, close all open applications, then shut down your computer ...unplug router and modem

Power up the modem first and after it gets initialized and all the lites are steady..
power up the router...after all the lites are on...
power up the computer

The above steps should take care of your problem

no joy then try this..

TCP/IP stack repair options for use with Windows XP with SP2.

For these commands click on Start.... Run..... type in...CMD ....press enter....to open a command prompt box

Reset WINSOCK entries to installation defaults...type in ... netsh winsock reset catalog .... press ...enter

Reset TCP/IP stack to installation defaults...type in...... netsh int ip reset reset.log ... press ...enter

Thanks happyrck,

but neither of those suggestions worked for me

;(

John Hook - I am on Telstra Cable, and it suddenly stopped working a few weeks ago, after it had been working fine. I am almost sure this is something to do with the IP addresses not matching up or something.

Try fushing the DNS.

  • Go to Start -> Run.
  • In the Box, type in "cmd".
  • A black box will appear. Type in: "ipconfig /dnsflush".
  • This should clean your DNS cache.

Argh, stupid me.
I'm so sorry.
The correct one would be:

Ipconfig /flushdns

Again, I'm so sorry.

No problem.

The DNS has been successfully flushed, but there is still no change in connection.?

A few questions.
If you plug in the cable from your internet directly to your computer, does the internet work then?
Is your router correctly configured?

well to connect it directly we'd have to run a cable through the whole house- my laptop works fine on the wireless network though, so does the other PC.

Is there a way to synchronize the IP addresses? One might have the wrong one or something?

Could you run ipcofig/all on all the computers on that network and show me?
IP addresses are things that should be unique. Just like your home's address.
