I recently came back from a trip to find my dad complaining of the internet no longer working on his laptop. He said he didn't do anything to it, he just turned it on and tried to go to a website, and it wouldn't work. This problem happens on both IE and Firefox, as well as any other program that tries to access the internet (like the Anti-Virus looking for updates).

The computer connects wirelessly to a home network to get to the internet. Two other computers on the network also connect wirelessly and work fine. Also, one computer is connected via ethernet and it is also working fine.

The computer does connect fine to the home network. It says it is connected and with a strong signal strength, and does not give any indication of a problem. However, anything internet-related will not work. However, accessing network drives and networked printers works fine.

I've tried repairing the wireless connection, but that had no effect. I set up this network and am pretty comfortable with most networking aspects, but I've never had a problem like this before, so I'm not sure what else to try. Any suggestions are greatly appreciated.

Have you checked configurations on the router? Sometimes power surges are known to revert setting on a router back to default.

Have you tried: ipconfig /flushdns?

Can you ping 72.14.207.99?

Does you ISP use PPPoE?

Have you tried plugging a PC directly into the modem?

Also, a simple one, have you power cycled the the modem and the router?


Give those things a try and let me know the results.

The router configuration is fine. Remember, all computers but one that are connecting through this router work fine.

ipconfig /flushdns had no effect on the situation.

Yes, I can ping 72.14.207.99. Hmm, this is surprising! I can also ping google.com, yet cannot visit it using Firefox or IE.

Yes, my ISP uses PPPoE.

The laptop has no ethernet port, so it can't be connected directly to the modem.

Yes, both modem and router have been power cycled.

Solution:

1. Type netsh winsock reset in the Command Prompt.
2. Restart the computer.

Thanks for your time, Titan.

Edit: Upon closing Firefox, and re-opening it, the problem started again. Argh!

Are there any signs of malware on this computer?

Which antivirus program are you using? It's likely that your AV program is blocking your connection. I would try reinstalling your AV program.

Actually, I hadn't heard from him in a while so I assume that he resolved his issue. If I had to guess I would say he was another victim of the Windows Update that made Zone Alarm user's internet inoperable.

Ah, yeah, I had that same update and Symantec AV didn't like it, but I reinstalled the AV program and it let me through.

Hey guys, sorry for the late reply, but I had gone away the day after Titan's last July response, and I had become unsubscribed to the topic by the time I returned. Anyways, I managed to solve the issue by doing a clean re-install of XP. Laptop works much faster now too, as my dad had a bunch of junk on it. I don't think Windows Update was the issue, because Automatic updates were turned off and he said he didn't install any updates. (I believe him, because he honestly wouldn't know how to update manually. )
