Sadly non of the listed things helped.
I already had the best bios update.
I updated the chipset driver, but nothing.
I reinstalled the latest network driver but nothing. I guess it is a hardware issue. If you know anything else that can maybe help i am always watching this post. Thanks for your quick respond.
