Disconnecting precisely every 2h04m

this behavior started a few days ago, vpilot disconnects after exactly 2 hours 4 minutes.

any ideas? an isp problem? vpilot? vatsim itself?

reliably:

alright. I appear to have come across a specific solution.

its something with netgear routers, a bug going back many years apparently. the solution is to turn on QoS (quality of service) which is some proprietary bandwidth management system. nobody knows why it works but it does.
