Public NTP server interaction, used for system time initialization
If DHCP option 42 is provided in the DHCP response from the local DHCP
Server, the Network Extender will try to sync with the local NTP server IP address
provided in option 42.
If the above is not provided (it's not mandatory), the Network Extender will try to
resolve the following public NTP.org FQDNs and attempt to get NTP sync from
the public NTP servers.
NTP uses UDP/TCP port 123

Description
If DHCP is on, this field is read-only. It shows the DHCP allocated Secondary DNS
Server's IP address. If DHCP is off, this field is read-write and shows the user-
defined Secondary DNS Server's IP address.
If DHCP is on, this field is read-only. It shows the DHCP allocated IPv4/IPv6
address. If DHCP is off, this field is read-write and shows the user-defined
IPv4/IPv6 address.
If DHCP is on, this field is read-only. It shows the DHCP allocated Subnet Mask. If
DHCP is off, this field is read-write and shows the user-defined Subnet Mask.
This setting is used to keep the bandwidth consumption rate to under the specified
limit by limiting uplink traffic. The maximum 1Gbps value is the default setting and
should not be changed unless there is a strong need to limit the amount of data the
Network Extender can send. The Network Extender will not allow bandwidth
consumption greater than 150 Mbps, regardless of the value set here. The
Backhaul limit should never be set under 20 Mbps as it will negatively affect voice
call quality
This is the Maximum Transport Unit (MTU) used to create IP Packets.
This setting adjusts the maximum packet size for data transmission over the
network. The default setting should be used in most cases. If the Maximum
Transmission Unit (MTU) size is set too high, users may experience poor voice
quality and increased latency in their data service. If set too low, overall bandwidth
consumption will be increased and users may experience lower data speeds.
