I've tried many ways that was mentioned and I've called my internet connection supports and they told there must be a problem with my setting in laptop and again tried several ways with no result!!they told me that it must be s.th about using antifilter but all the way that must be related to proxy wasen't the answer.
I've tried these:
IE: Internet option>connection>lan setting>uncheck
IE:Internet option>general>delete browsing history
and also in fire fox proxy is uncheck too.
try this software that s.o suggest: " winsockfix"
start>run>cmd--------> I've tried several things like checking "ping" etc.
I'm so confusedddddd!!!!please HEEEEEEEEEEEEEEEEEELPPPP!!!!!!
