I am absolutely baffled. I hope someone can help me.

Computer is an HP Pavilion a720n
AMD Processor
512mb RAM
Windows XP Pro v.2002 SP 3

A customer called me the other day complaining they could not get on the internet. I've done all the ususal steps. Cleaned up malware, turned off firewall, rebooted cable modem, Netgear router and computer. Checked LAN drivers. All installed properly. Customer also tried installing a new PCI Network card to no avail. However, when they hook up either of their two laptop's both get online, either wirelessly or with cable.

So I take the computer back to my shop thinking its some kind of hardware issue. I hook it up to my network and the thing gets right online, no problem at all. In fact its this computer I'm using to type this message. I take it back to the customers house and no internet. I bring it back here again and sure enough I have internet.

I don't get it. Anyone have any ideas??

Thanks

Robert

did you try pinging any sites? or you just relied on a browser to tell you no internet? Does it get an IP address from the router? does it have a static IP? Did you release/renew the IP? Did you connect it directly to their modem and see if it can surf?

I did disconnect the router and connected the computer directly to the cable modem. I did /flushdns, /release, /renew. Did get a 169.xxx.xxx.xxx number and a subnet mask number. However, I did not try to ping any sites.

well the 169.x.x.x means it is not getting an IP address. When you hooked up the laptop(s) wired did you use the same wire you used for the PC? I am hoping not, cause that is the only thing in the chain you haven't said was working.

The NIC is OK cause it connected at your place. The router is OK because the laptops connected wired and wireless. But something is stopping the PC from getting a proper IP address. You could assign a static IP and see if it will connect.

If it has a 169.x.x.x IP it won't ping anything so no worries about that.
