While trying to install software-updater software updater in my pc windows 8 it often says "network error--Nokia software updater has attempted to connect to the internet but has failed three times. This could be poor quality, slow or intermittent network connection, or firewall firewall restrictions. If the use of network proxy is required in your network, please check the application's network setting."
I allowed it from firewall restriction. But could not operate. So please suggest me how to solve this problem
