I am using a windows 7 premium OS compatible Acer aspire laptop, which i basically use for internet access from both of my official and home network. I am using this machine from approx more than a year. I am using a secure authentication network service at my home. There is no problem with the network service also with the machine till last few days back. But now from last two days I am facing a problem in my machine with the network connectivity, I usually enter my network secret key, whenever I tried to connect my machine with network. Now the problem is, when I enter the network key it says that, the windows cannot fine the windows cannot find the network to put the key. I canít understand what this message means. I hope someone from here will definitely help me to overcome from this problem.
