For example when I type in
www.gmail.com the Website is loading very slow. On any other device my mailbox is instantly opened. The same with
www.google.de. Youtube sometimes does not load or the video pictures are appearing very slowly. Besides that my Office 365 Outlook does not connect instantly, it takes some minutes to get the connection.
I have tried three different browsers, same result.
I figured out that this behaviour is the same with Ethernet cable connected. Due to this is a Azure AD managed device it might be a new security realted setting. I will geht you updated when I got more information
