    Can't surf the internet on my laptop because the DNS lookup keeps failing in chrome and firefox. There are three other computers in the house all with working internet so I am sure it isn't the router or modem. My wireless internet is a built in Atheros AR5007EG and has working perfectly for two years but stopped a week ago when we switched cable providers to AT&T, though none of the other computers were affected. The wireless status symbol on the start bar tells me that I am connected to the network, but when I ping google.com in the command prompt the ping request can not find host google.com. Help? My laptop is a windows xp

    results from ipconfig /all when let the DHCP and DNS set themselves:

    From a Johnwill post

    IP addresses of all zeros are normally caused by one of the following.

    Diagnosis:

    1. DHCP Service not running.
    2. Duplicate IP address on the network.
    3. Bad NIC card drivers.
    4. Defective NIC hardware.

    Resolution:

    1. Check Control Panel, Administrative Tools, Services. The DHCP Client service should be Started and its Startup Type should be Automatic.
    2. Turn off ALL of the computers and other network connected devices, restart (power cycle) the router, then restart all the computers and other network devices.
    3. Check for upgraded drivers and/or reload the Network drivers.
    4. Replace the Network Interface Card.
