21: No address assigned by DHCP server
What to check on the transmitter
On the transmitter, IP address is set to [Auto setting]. Is this
the correct setting?
If no DHCP server is used, configure settings after setting the IP
address to [Manual setting] on the transmitter (p.94).
What to check on the DHCP server
Is the power of the DHCP server on?
Turn on the DHCP server.
Are there enough addresses for assignment by the DHCP
server?
Increase the number of addresses assigned by the DHCP server.
Remove devices assigned addresses by the DHCP server from
the network to reduce the number of addresses in use.
Is the DHCP server working correctly?
Check the DHCP server settings to make sure it is working
correctly as a DHCP server.
If applicable, ask your network administrator to ensure the DHCP
server is available.
What to check on the network as a whole
Does your network include a router or similar device that
serves as a gateway?
If applicable, ask your network administrator for the network
gateway address and enter it on the transmitter (p.89, 94).
Make sure that the gateway address setting is correctly entered on
all network devices, including the transmitter.

Also check the following points when responding to errors numbered 21 - 24.
Are the transmitter and the access point set to use the same
encryption key for authentication?
This error occurs if the encryption keys do not match when the
authentication method for encryption is set to [Open system]. The
setting is case-sensitive, so check upper- and lower-case characters.
Make sure that the correct encryption key for authentication is entered
on the transmitter (p.27).
