Protocol: Chooses between Static address, where you
can specify the device IP address, or DHCP client,
where the device obtains it IP address automatically.
Static address is necessary if other devices obtain
internet connection through this device. Static
address is also recommended if you wish to configure
the device via the web interface.
Protocol – Static address
IPv4 address: Sets the IP address of the device e.g.
192.168.21.1, where you can access the radio's
configuration web page.
IPv4 netmask: Sets the subnet mask e.g.
255.255.255.0. The IP address and netmask together
determine the subnet or network ID e.g.
192.168.21.0/24. Two devices must be in the same
subnet in order to establish a (Layer 2) link between
them.
IPv4 gateway: Specifies the IP address of the remote
server that allows the device's shell to gain internet
access.
IPv4 broadcast: Specifies the IPv4 broadcast address,
optional.
Use custom DNS servers: Configures the IP address of
the DNS servers e.g. 165.21.100.88 for the SingNet
DNS server in Singapore or 8.8.8.8 for the Google DNS
server in the USA. The computers in the same subnet
as this device can then set this device's IP address as
their preferred DNS server to obtain the same DNS
service.
Protocol – DHCP client
The Dynamic Host Configuration Protocol (DHCP) is a
standardized networking protocol used by servers on
an IP network to allocate IP addresses automatically
to client devices.
Hostname to send when requesting DHCP: Specifies
the name of this device as seen by the remote DHCP
server.
Advanced Settings
The following are options in the Advanced Settings
section tab. Some of these options are shown,
depending on the protocol being used.
Override MAC address: Allows you to specify a
different MAC address other than the radio's original
MAC address. This is useful if the ISP uses the MAC
address of a radio to identify a customer. Suppose
that the radio needs to be replaced. The new radio
can take on the MAC address of the previous radio in
order to continue having internet access.
Override MTU: Sets the maximum transmission unit
(MTU), the default being 1500 bytes. Unless, your ISP
requires, it is not recommended to change this setting.
Use gateway metric: Allows you to specify a gateway
metric. This acts as a cost for choosing the gateway
when a connected device has to select between
multiple available gateways. The gateway with the
smallest metric is chosen.
Use broadcast flag: When sending DHCP requests, a
client can indicate if it wants an answer in unicast or
broadcast, by setting the broadcast flag. This is
required for certain ISPs. Unchecked by default.
Use default gateway: Configures a default route.
Checked by default.
Use DNS servers advertised by peer: Uses the DNS
settings advertised by the DHCP server. Checked by
default.
Client ID to send when requesting DHCP: Sets the
identifier that may be required by the ISP or network
