I have a Vaio laptop that has Windows Vista installed in the same. It is a new system. I had configured the laptop to work with my home wifi connection. Later on there were some updates that were downloaded and prompted for system reboot. I did the same and then somehow the internet failed to work. I have to restart the same a number of time and then only the system works well. I am facing problem with the network connectivity. Does anyone has idea on the same why this problem appears.
