Windows DNS Flush Cache

First try: unplugging both router and modem for a few minutes. Reconnect and if there are still problems, try the below.

I am not sure if you need to be having DNS configured for your Win XP system. It will depend on kind of internet connection you are using. Since you are using wire free, and are getting dynamic IP assigned everytime you logon then you are on DHCP. Based on this IP allocation to your system will dynamic.

To check at command prompt run ipconfig /all, check DNS server are listed. To start DNS client, click START button > click Run and type services.msc and hit Enter button. This will open services and now you can right click on DNS client and Start the service if its not started. What starting DNS client will do is it will resolve and cache Domain Name System (DNS) names.

Once you do so, at command prompt run ipconfig /flush. Then run ipconfig /release and then ipconfig /renew. That should do it.

In case you are still unable to surf net, try to ping your default gateway ip and check with the link or finally contact your ISP support for further assistance.
