Problem solved after updating to Win 10
it started two days ago, every now and then i start getting one of these errors (or all of them) :
the most frequent one is :
When this one appears, google searches still works (from the address bar) but i can't open any websites, including google.com or youtube.comERR_CONNECTION_FAILED
then there is :
This one happens with certain websites, like speedtest.net, actually it is happening right now while am righting this post and google and eightForums and other websites works perfectlyERR_CONNECTION_RESET
Also sometimes the internet in the browser is completely down, nothing works while skype & dropbox and steam are still working, and sometimes nothing works.
Like i said this happens with wireless and wired network.
I am sure that my internet and my router are fine since i tested it with 5 devices (win7 laptop, ubuntu laptop, macbook, Android smarthone and an iPhone)
Also i just want to say that my internet in this pc has become very slow, while in other devices it's constant 8mb/s.
I am trying to update the pc to win10 at the moment and it's been 2 hours and the download is only 2% ...
I tried netsh winsock rese and restarted the pc and the router and the problem still persist.
I turned off completely my anti-virus (avast free) and all other security services from Microsoft and still couldn't find a solution for this.
I have a doubt that this is related to my other problem,"can't save settings like default app, folder and icon size", and i was going that upgrading to win10 will solve all this but i clearly can't do it with a broken network.
Can anyone help me to solve this please ?
Thank you and have a good day
