Section 3 - Configuration
The Quality of Service screen will allow you to set priorities for traffic passing
through your network. By default all types of traffic are assigned the same
priority. Multimedia applications use UDP (User Datagram Protocol) for
data transfer, while database applications use TCP (Transmission Control
Protocol) for data transfer. Rule 1 priority is higher than Rule 2. After you
have completed you prioritization settings, click Update.
If you forgot the encryption key, click the Reset button to reset the node,
which will restore the initial factory configuration. You can only reset a
node connected directly through Ethernet.
To upgrade the firmware, click Browse and then locate the firmware file
and click on Upgrade Firmware.
