after upgrading my win7 to win8 today, I found I could not get online properly , totally blocked.
After a long time testing ,reinstall win8 and all the software, I found that it is caused by Avast Free network shield module , once the module disabled,I could go perfectly online and once the module is activated , my network is blocked again .
now my solution is to deactivate the network sheild forever , I hope someone could give me a solution to solve it , my avast has already updated to the latest ver.
Thanks
