can connect to router but not internet

Sony Vaio vgc-rb40 desktop
August 4, 2009 at 22:41:35
Specs: Windows XP Home SP2
It all started with the installation of SP3! Network stopped working in spite of numerous forum searchs for answers. Tried them all, nothing worked. Rolled back to SP2 and was able to connect to the Internet...for a while. Current status is can connect to router with a direct connection, but can't browse and no access to email.

Do have 4 other laptops/desktops in the house, all connecting wirelessly via WEP.

Equip:
Sony VAIO VGC-RB40 Desktop (system in question)
- Intel PRO/100 VE NIC
Netgear wired/wirless-G router WGT624 v3
LinkSys cable modem BEFCMU10
ISP: Cox Communications 7Mb/512Kb
WinXP Home SP2, ver 5.1.2600

DNS Servers . . . : 192.168.1.1

Try the DNS of the ISP instead.

Side notes: HOME <20> UNIQUE Registered
You have file sharing enabled. Make sure the machine is password protected.

Secondly, change the default password of the router since WEP will only keep newbies out.

Thanks for fast response.

Turned off file sharing. Had enabled to share a printer.

All other three machines that wirelessly connect work fine and have a DNS server showing 192.168.1.1. I did manually enter the three DNS servers offered by Cox. No change.

I always change router default password to a strong password - thanks though.

While I was at it, I reset the IP and Winsock stacks:
netsh int ip reset reset.log
netsh winsock reset catalog

Other ideas?

The next thing is your firewall. Did SP3 makes some changes to it? I seem to remember something about that. Disable it for testing & look at secondary firewalls, such as Norton.

I have SP3 and Norton too and had no problems when I went to SP3 but I have heard of other people having problems. Their solution I think was to update their Wireless NIC drivers because they were not compatible with the new service pack. Have you tried downloading new Wireless NIC drivers yet?

Also, you can determine if it is a DNS problem or not by pinging the IP instead of the FQDN like...

Pink 69.147.114.224

Instead of

Ping Yahoo.com

If you get a 100% packet loss then it is not the DNS.

also are the other laptops having the same problem or are they on SP2?

I have four systems on the network:
HP/Compaq 6710b, XP Pro SP3,
Fry's Electronics laptop, Windows Vista SP2
IBM R40 laptop, XP Pro SP2
Sony VAIO desktop, XP Home SP2 (system in question)

> There are no problems with any of the other systems.
> All other systems connect wirelessly.
> The VAIO is direct-connected to Netgear router and and I have tried all four ports and multiple cables. No change.
> I have also connected the VAIO directly to the cable modem. No change.
> Windows Firewall and AVG Antivirus are disabled
> I can ping yahoo.com or 209.131.36.159 and both work with an average of 37ms round trip

Try doing a IPCONFIG /FLUSHDNS then a IPCONFIG /REGISTERDNS

The /flushdns & /registerdns commands didn't effect any change. I have also tried entering my ISPs static DNS server addresses into the client TCP/IP setup, didn't help.

In the past on various occassions, I did have an duplicate IP address conflict on the network. I usually noticed the message on another on of my laptops. The situation usually cleared itself up so I never examined the system in question (the VAIO.) Searching the event viewer for the VAIO, I did find the same error message.

I have done an address reservation on the router for the VAIO only, rebooted all machines as similtaneously as possible, multiple times, trying to recreate this isssue. It has not happened so I believe I can rule out the duplicate IP issue.

Interesting that I can't ping my own IP address from the VAIO, 192.168.1.2, while on every other machine, I can ping it's IP address.
