Hello Sir, my laptop was running fine just yesterday until I bought a book on Amazon Kindle site and tried to download it which failed to download. But unfortunately just after that my proxy LAN setting got disconnected. And since then even after resetting the proxy address the connection goes off no matter how many times I reset the address. The proxy address remains address less even after setting the address. I am in serious trouble as I could not stay connected to the LAN for less then 5 seconds. Any help would be most gracious.
