Clarifying throttling of Fiber speeds with BGW320-505 in passthrough mode
We had 500MB fiber service installed earlier this week and received the BGW320-505 gateway. Aside from some install hiccups with a line cut in our area, once the service was turned on we were seeing a steady 500MB both up and down on our service. For work reasons, I can't use the BGW320-505 as a router and I installed my own Sonicwall router behind the BGW320-505 and switched the BGW320-505 to IP passthrough mode. Everything works, but I've noticed reduced throughput (~120mb up and down) since installing my router. While it's entirely possible (and likely) that the router is something of a bottleneck here, I know this particular router used to max out a 200+mb connection when used in a previous home. I've seen some references on this forum to ATT throttling connections in passthrough mode. Is there any truth to this? Are there other factors I'm not considering that could result in reduced bandwidth using the passthrough on the BGW320-505?
