In my whole flat the internet is good. In the all places where i ping google.com i got about 23ms. I have router on my table but when i put my mac on this table and try to run something on internet i get ping spikes but huge ping spikes. The average is something about 600+ms and can get over 3000ms easily and lots of time i just got "Request timeout for icmp_seq". The sites are loading endlessly and also playing some youtube video is impposible. But i dont get it beacuse the mac is close to the router.When i take mac of that table i got back 23ms and everything works fine. My flat mate is using Windows OS and he didnt get this ping spikes likes me. When i am at my mums flat where is 5g 500mbt/s internet i also dont have this problem.
I tried to restart the router, deactivating my firewall, deactivating localization on my mac but still nothing helps me.
