• Make sure the Ethernet cable is connected properly to the NSA and connected to
another (Ethernet) device. Make sure the other device is turned on. If it's
connected directly to a computer, make sure that the computer network card is
working (ping 127.0.0.1 on the computer).
• Use another Ethernet cable. If you're connecting to a Gigabit Ethernet, make
sure you're using an 8-wire Ethernet cable.
• If the problem continues, contact the vendor.

download task after it restarts.
