Hi, i have linovo z560 with windows 7 os. I had macffee antivirus and now its subscription is over so i have uninstalled this from my machine. My problem is when i am using internet it suddenly goes down and shows "No Network Access", it shows the available networks in the lists and the one which i am connected in internet connection lists. when i clicked on the network connection, it shows me limited access but i am not able to access the internet with the limited access. when i click on troubleshoot the problem, machine gets hang while resolving problems. if i disconnect the internet connection and try to connect it shows me "windows was unable to connect to this network" . And all the networks removes from the lists. If i restart the machine sometime it works. i am not aware why this issue started. i dont have old backup to restore and start working. i have some recent backup and i have resstored but it is not working. Can someone give me direction to resolve the issue? i am very much frustrated with this issue and trying to resolve this issue since long time. Thanks in Advance.
