i changed my isp to have a better internet few days ago. My laptop is a new Asus 15", i7 4k display with intel 8265 e realtek 8211.
if i do a speed test with antergos live (18.9) i get a ping of 240-250ms and the upload speed of 0.3 Mb. I have same performance with wireless and cable
if i use other distros live: manjaro 17.1.2, ubuntu 18.04, fedora 28 i have the normal expected speed: ping 15ms and upload 3Mb
tnx a lot
