So last night I was running a campaign on Roll20.net and using Vent for voice communications. At random, my ping in Vent would jump for ~60 ms to an astounding ~12,000 ms. Audio would get backed up, and nothing was going through on Roll20. Then when it finally cleared I would get bombarded by audio and messages in Roll20.
Any thoughts as to what I can check to narrow this down? Using something like SpeedTest is pretty much useless as it is only a snapshot in time, and it always ends up showing a ping between ~40 and ~60 ms.
I am on Comcast cable internet, and am using a WD Livewire powerline system
to have a hardwired connect at my PC, as when I was using wireless the signal just wasn't very strong.
