I am away from home.
My wife at home cannot access the internet with her laptop.
I suspect the problem is in the home server I am responsible for.

In brief, the internet can be accessed from the CentOS-6.4 server.
Her laptop accesses a WiFi router which is connected to the server.
I have to confess that she is the only household member
running Windows - Windows XP in her case.
Connect to=>Show All Connections shows the WiFi connection is good.
But she cannot access the internet, or ping google, etc.

I can get access and login to the server from far away.
I see nothing wrong.
I have restarted the network, dhcpd and shorewall services.
I checked that forwarding is on.
I can ping my wife's laptop from the server.

Her setup has been working fine for months if not years,
accessing her work over VPN.
But now she is just trying to browse.

I'm not sure what tests I can run to diagnose the problem.
Any suggestions very gratefully received.
They may save a marriage ...

Step 1: Reboot the WiFi router. It may have lunched its routing tables.
It happens.

Step 2: Reboot her laptop. Not a warm boot (ctrl-alt-del), but
a full-tilt cold boot from power off. You say she uses a VPN to contact
work, and it's often that the VPN clients leave crumbs in Windows'
routing and DNS lookup tables.
