The USB Ethernet adapter gets disconnected from the USB bus on suspend and re-discovered on resume. ifconfig will show that it does not have the autoconf flag set nor does it have any IPv4 addresses configured. Effectively it becomes a new device on resume. I'm not aware of any way to fix / work around this. Calling netstart(8) from apm probably races against the kernel and the USB adapter might not be there yet when it runs. > > Is this kind of behaviour expected?
