I replaced my old modem and router with a used Netgear C6300BD modem which has a built-in router
I did this because Spectrum claimed they had raised my speed from 100 mbps to 400 but my old modem was not capable of such a speed.
My speed is much better now. It used to be around 15 mbps. Now when I connect to the 5ghz ssid sometimes it goes as high as 200mbps according to speedtest.net.
And yet my video conferences on Zoom is MUCH WORSE than before. It hangs constantly. And not just on one device; I tried on another laptop too. On my old setup it hung very rarely. Also noticed that YouTube on Samsung smart tv also takes it awhile to show the thumbnails.
Does anyone know why this is? Something about "latency"? But the internet provider is the same company. So something wrong with the new modem? How can I troubleshoot this?
I did a test at this place: https://packetlosstest.com/ And it says my avg. latency is 194 ms and avg jitter is 198 ms. screenshot here: https://static.md/da00cd158964d46a5df880af64ecfe65.png
But the speedtest software I installed on my laptop says my jitter is only 6.87 and my ping is 12 ms.
So I don't which is right and how to know for sure.
Thank you in advance.
