As the list in the Web-UI in a netgear router is correct,
I assume it gets the names from the DHCP requests the clients
are initiating. From /etc/sysconfig/network/dhcp:

## Type: string
## Default: AUTO
# specify a hostname to send ( -h option)
# specifies a string used for the hostname option field when dhcpcd sends DHCP
# messages. Some DHCP servers will update nameserver entries (dynamic DNS).
# Also, some DHCP servers, notably those used by @Home Networks, require the
# hostname option field containing a specific string in the DHCP messages from
# clients.
# By default the current hostname is sent ("AUTO"), if one is defined in
# /etc/HOSTNAME.
# Use this variable to override this with another hostname, or leave empty
# to not send a hostname.

I also have such a netgear router - I have to look ...

Have a nice day,
