Why do I have latency and lag on the internet?

Episode 1048 (1:41:37)

John from Oak Park, CA

John takes music lessons on the internet to play the harmonica. The teacher uses Adobe's Meeting, but he has extreme latency issues. Leo says it could be hardware, but more likely it's the ISP's data flow rate with Adobe. It's causing a delay from Adobe to John and back. Leo suggests doing PingTest.net to see what the latency is. If it looks good, then the problem is with Adobe.

Adobe has a technote here which may help troubleshoot it.
