What sort of transfer rate can I get on an HD connected to the USB port? I have a sata/usb bridge with a 1Tb sata2 HD connected and tried both RT-N16 & 3500L. To cut a long story short I can't get anything more than 3.2 MByte/sec. Initially I thought it could have been an USB 1.1/20 issue but on the usb config page only support for USB 2.0 has been enabled. P.S. the data is coming from a NAS connected at 1Gb to the router itself. Perhaps I'm missing something...?
