Unfortunately, I was disappointed by the new technology. The 520E were always so in the 200 to 300 range. The 1000E should which theoretically provide up to 1000 Mbit were among 200 MBit. Even after a long wait to nothing did. Had wavering as to the 70 MBit. Processing equipment is solid as the older devices.
