skype with windows 8.1

Dear friends,


Im using skype for very long time. And i bought a new laptop last year with windows 8 and i used windows desktop skype since then. Modern skype (the one we can download from windows apps store) didnt work well for me. I dont know it was slow and really slow to respond. So i used windows desktop skype for windows 8. I had no problem with it

But after that i have updated my windows 8 to windows 8.1 and now both skype types are not working (desktop and modern skype ).
The desktop skype always says you have "internet connection problem" which i dont have. There is no any internet problem with me. Im saying this coz my mobile phone skype is working well in same wifi network (home wifi network). At the same time i can watch Youtube videos in my laptop. So laptop also dont have any internet connection problem .

So i dont really find what is wrong with my skype. here is my skype calling procedure
I m rining my friend
then he answer the video call
then after 30 s or one minute time it says internet connection problem ,
it automatically rining back or something like that happen.
then i disconnect the line and get the call back again.
and same thing happen over and over again

please help me on this. I have re-install the skype now for 3 or 4 times . but the problem still persists

 

You could also check your firewall settings, maybe something changed when you did the update. It should be working, desktop skype has been working for me on all recent versions of Windows, even 8.1 upgraded from 8. It's always possible something went wrong during the upgrade process.

 

Sometimes my VGA drivers says its not compatible with the new operating system. Is that the issue?
