I have been successfully running Windows XP, Service Pack 2, for a long time, without any problems connecting to my router, to the cable modem and to my Internet Service Provider. Then, for some unknown reason I received the Limited or No Connectivity message. I've tried a number of things to no avail: ipconfig /release and /renew, uninstalling and reinstalling the network driver on my built-in adapter, installing a PCI network adapter, recycling my router, changing CAT 5 cables and running WinsockXPFix. I'm still left with the Limited or No Conncectivity message and no connectivity to the Internet.

I have 3 desktop computers in my home as well as a laptop and I have switched ports between the various computers with no change in results. The same computer still cannot connect to the Internet while the other computers are fine. I can plug the CAT 5 cable into my laptop and the connection works just fine. When I plug the CAT 5 into the offending desktop I still get the Limited or No Connectivity message.

I could definitely use your help. Thank you.

I had a similar problem with the wireless on one of my laptops a while back. It suddenly stopped connecting to my router, very much like yours. What happened with mine was that for some reason the router was failing to communicate with the laptop and it was not properly assigning it an IP address. One thing you can try is manually configuring the IP on the offending computer. Since you have working ones it'll be pretty quick.

1. On one of the WORKING computers, go to Start>>Connect To>>Show All Connections.

2. Double-click on the connection you are trying to use so that it opens in a new window.

3. Click on the "Support" tab, then click on the "Details" button.

4. Write down the IP address, the subnet mask, the default gateway, and both DNS servers.

5. Get on the offending computer. Go to Start>>Connect To>>Show All Connections.

6. Right-click on the connection you're trying to use and go to "properties"

7. Scroll down to the Internet Protocol (TCP/IP) icon and click the "properties" button

8. Check the bubble/box that says "use the following IP address:" and then fill in the subnet mask and the default gateway with the same numbers as you got on the other computer.

9. Do the same for the DNS settings at the bottom.

10. For the IP address, fill in the first 3 sections with the same numbers, but for the last one pick any number between 1 and 255 that isn't selected. I usually just use something like 10 or 20

11. Hit "OK" on all of the windows that are open and see if that fixes the issue.

I can't guarantee this will work, but as I said, I had what sounds to be a similar problem, so this is at least another option to try (since you've clearly tried many others already). Let me know if anything changed after you configured it manually.

After manually entering the connection information I now receive a "Connected" status, but still no internet access. I would guess it has something to do with DNS. I did an ipconfig and the IP Address, Subnet Mask and Default Gateway all appear with valid information, but there is no information listed for Connection-specific DNS sufffix.

[ThPenguinsRComin]

Did you try manually configuring the DNS, too? Or just the IP address?

[LC123]

Yes, I manually configured DNS as well.

[LC123]

I had previously run winsockxpfix without any luck. However, I ran that program again and still no luck. After running the program I did lose my static IP address so I reentered all of the information: IP address, subnet mask, default gateway, preferred and alternate DNS servers.

As happened when I previously did this, I received "Connected" status, but I still have no internet access. When I ran an ipconfig in the DOS command prompt I see the IP Address, Subnet Mask and Default Gateway information, but there is no information listed for Connection-specific DNS sufffix. This despite the fact that I manually entered preferred and alternate DNS servers in the IP properties.

[ThPenguinsRComin]

Hm...I wonder why your DNS won't hold...try doing this:

Go back into the IP properties for your LAN connection as if you were going to change them manually again. Leave everything set up manually the way you have it, and click the "Advanced" button in the bottom right. Click on the DNS tab along the top and then hit the "Add" button under the top box. Fill in your primary and alternate DNS server addresses in there, and put the primary in the first slot. Then close out and see if it'll hold your DNS server addresses after that. It's strange that you're getting the "connected" message if you aren't really...

The other thing you may want to try is going into DOS and running ipconfig/flushdns followed by ipconfig/registerdns, if you haven't already.

[LC123]

Still no luck with DNS. I've tried both of your suggestions: 1) Using the advanced tab to enter the DNS server addresses, and 2) Flushdns and registerdns via the ipconfig command. Still have "Connected" status but no access to the internet.

Other thoughts?

Hi LC123,

Just a few questions.

Can you post a ipconfig /all from a working PC please.

Also are you able to run this command "ping www.google.co.uk" successfully from the problem PC?

And what does the command "nslookup 212.58.224.81" result in?

Any ideas on how to proceed? I'd like to get my computer operational again.

[Pseudopath]

Thanks for the info.

Okay another couple of things please.

Can you post the result of this command on the problem PC "ipconfig /all".
And would you please try this command too "ping 192.168.1.1".

Thanks,

made any changes to your software setup lately? like a new firewall or antivirus software maybe...try disabling any security software you have on temporarily and then trying to connect...

have you tried connecting directly to your cable modem, theres nothing wrong with the router coz it works to the other PCs, I'd still try connecting directly to the cable modem(if possible) ...

also the next time you get "limited or no connectivity " try going to my network places and then right click on the connection you are using select properties and under the General tab uncheck the checkbox that says notify me when this connection has limited or no connectivity and then reboot the comp...see if this works

hope this helps iam not much of an expert, just learning stuff as i go along
