DNS - Networking Issue

[stormedcrow]

Hey all, I'm getting some odd problem. When I try to access a website the browser says that the DNS is not resolved. But after a couple of seconds it responds, finds it, and opens the page. And that for everything on the internet. Remote control also fails for a second then works again and it keeps semi buffering to the point of frustration. I have tried changing the DNS to google, changing the IP but it just seems not to work. Has anyone an idea what could be wrong ? What is even more interesting, when I dual boot on ubuntu (seperate hard drive) these errors do not occur. Everything is stable.

nslookup google.com -> https://pastebin.com/J8FrD0UM
/etc/resolv.conf -> nameserver 8.8.8.8
ip a -> https://pastebin.com/VxbCUZ0E
ip r -> https://pastebin.com/nGFstCr5

I am using a static IP adress. The internet speed is stable (above 800MB/s). If I try to ping this specific PC I get a packet loss of 70% which means that the PC is probably having trouble finding the correct DNS/Proxy/Firewall.

MY first thought is that you have a duplicate ip address so some other device is getting the packets that ought to be going to your machine.

Hmm, but how come is that when I use the same machine on Ubuntu and ping it I get no packet loss whatsoever ?
