Hi everyone, I've got an issue with my internet connection : once in a while (like 3-4 times every day), my internet is very slow and when I test it with a ping, I see that about 50% of the parquets are lost (request timeout). That only happen on my iMac (10.13.5). My Macbook (WiFi) and my other PC with Linux have zero issue. Also it doesn't happen if i turn the WiFi on. It's only when I'm connected via Ethernet. I also tested multiple Ethernet cables but the problem keeps happening. Most importantly, if I then remove the Ethernet cable and put it back on, the connection is perfect again (0 paquets lost). If I do nothing, the connection issue can last for 5-10 minutes, sometimes more, then disappears. What could cause that ?
