I regular face these problems of "Requested Time Out", "Destination host / net unreachable" Can't understand where is the problem. I tried to follow this process of uninstalling and installing of tcp/ ip protocol. But, in my laptop, first I could not find LAN. We have a wireless network connected. When i saw the properties of WAN, the TCP/IP Protocol is already uninstalled. On clicking install button, there are three options client, service and protocol. Do I have to choose the protocol option? Would this process will stop the problem we are facing?
