    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?

  2. Yes, you must select protocol to complete the process. To check other solutions for the issues you are facing, visit the links below.

  3. I cannot uninstall TCP/IP because it is greyed out. The button cannot be clicked. Is it because it isn't installed? or?
    Thanks for your help
