Is it interference with other frequencies ? Is it the LPSS adapters I am out of idea what would cause this slow internet speed or at least unsteady speed. I know wifi range can be an issue and my next step is to test a wifi booster. I can't plug to the ethernet since the MacBook has no port. I tried DNS Cloudflare 1.1.1.1 and 1.0.0.1 and still nothing changed. Then, I changed the DNS to Google 8.8.8.8 and 8.8.4.4 Same thing, it gave me around around 100-200 Mbps for a while and came back to slow speed.

Well, it gave me around around 100-200 Mbps so I thought it was it, but later in the day it came back to 30-50Mpbs. I removed the existing Wi-Fi preferences in macOS Sierra in the system configuration I tested the ping which gave me 100% transfer with 0.0% packet loss which indicate that it's might not be a wifi problem but Internet. I removed the caches, cookies and navigation data, empty the trash, etc. I call the Internet provider and after troubleshooting and assessment of very good internet, the problem remains for this device apparently. Depending on where we are (close to the modem Internet speed can reach 500Mbps but it is normally around 200Mbps in the office). I tested the speed online for my MacBook Retina and it gave way below (30-60Mpbs) what it is use to be (200-300Mbps). Navigating on the Internet is fine, everything seems to work but only when it comes to video it just lagged, connection is weak and then come back to normal, etc.Įverything is still fast on the other devices, no lagging when using video platforms. Since September, my Internet provider offers me a high speed internet (up to 700Mbps).Īll of my devices including the one in question worked very well, particularly with video conference (around 300Mbps).īut recently, on the MacBook Retina, video on Google Meet, Zoom and Skype started lagging. I have a MacBook Retina 16 inch with macOS Sierra 10.12.6 I am turning to the community to see if a similar issue has arisen among other users.

For mac instal Antidote 11 v5.0.1
