Hi,

I have both rt3070 & rt3071 USB dongles, they are notoriously unstable with rt2800usb because of the massive packet loss and duplicate packets - an issue which has not found its solution for over an year. I believe the problem stems from the chip's DMA irregularities.

I think this is exactly why you're experiencing transfer problems, due to packet losses. When you're connected, please try and ping your peer or gateway and confirm if you experience duplicate (DUP!) and/or packet losses as well.

Walter
