Parameter Description
Lease Time
It specifies the validity period of an IP address assigned by the DHCP server to a
device.
When half of the lease time has elapsed, the device sends a DHCP request to the
DHCP server to renew the lease time. If the request succeeds, the lease time is
extended based on the request. Otherwise, the device sends a request again when
7/8 of the lease time has elapsed. If the request succeeds, the lease time is
extended based on the request. Otherwise, the device must request a new IP
address from the DHCP server after the lease time expires.
You are recommended to retain the default value 1 day.
Subnet Mask
It specifies the subnet mask assigned by the DHCP server to devices. The default
value is 255.255.255.0.
Gateway
It specifies the gateway IP address assigned by the DHCP server to devices.
Generally, it is the LAN IP address of the LAN router connected to the internet. The
default value is 192.168.0.1.
Only through a gateway can a LAN device access a server or host which is not in the
local network segment. You are recommended to enter a gateway IP address which
can access the internet. Otherwise, the device in the LAN network cannot access
the internet.
Primary DNS Server
It specifies the DNS server address provided by your ISP. If you do not know it,
please consult your ISP.
To enable devices to access the internet, set this parameter to a correct DNS server
IP address or DNS proxy IP address.
Secondary DNS
Server
It specifies the second DNS server address (if any) provided by your ISP. This
parameter is optional, which indicates you can leave it blank if your ISP does not
provide this parameter.
If another DHCP server is available in your LAN, ensure that the IP address pool of the AP does not overlap
the IP address pool of that DHCP server. Otherwise, IP address conflicts may occur.
7.3.3 DHCP clients
If the AP’s DHCP server function is enabled, this module enables you to view detailed information about
devices that obtain IP addresses from the AP’s DHCP server, which includes host names, IP addresses,
MAC addresses, and lease times.
