Join a Network
If this mode is selected, the device will scan for available networks and attempt to join the
network specified by the SSID setting. If for some reason the device cannot join the desired
SSID (that is, network out of range or incorrect parameters), it will go to a low power state and
periodically (approximately every 1 minute) retry.
Create a Network
The NL241 can be configured to create a network. In this mode, it acts as the access point
which other Wi-Fi enabled devices can join. If this configuration is enabled, the user may set an
SSID (network name) and password. If a password is supplied, the network created will be
secured by WPA2 encryption. If no password is supplied, the network created will be an open
network with no encryption.
If this mode is selected, the channel may be specified manually using the Channel setting in
the Settings Editor. If the Channel setting is left at the default setting Auto, the device will only
use channels 1, 6, and 11 on which to operate to minimize interference from other networks
detected in the area.
When manually selecting a channel, it should be noted that two Wi-Fi networks operating on
the same channel will interfere with each other and will have to compete for bandwidth. The
center frequencies of adjacent channels are 5 MHz apart and the bandwidth of each channel is
20 MHz which means that adjacent channels overlap. To completely avoid interference there
must be a spacing of at least 5 channels between each Wi-Fi network. It is therefore
recommended to use channels 1, 6, and 11. For a list of all the wireless networks in the area and
the associated channels on which they operate, see the Settings Editor > Wi-Fi Wireless
Networks in Area box.
A network created by the NL241 supports up to 8 joinees.
B.2.3 Network Name (SSID)
The Network Name (SSID) setting is the name that identifies a wireless network (31- character
maximum). The SSID differentiates one wireless network from another, so all devices attempting
to connect to the same network must use the same SSID. If the device is configured to Join a
Network, enter the SSID of the network to join here. To join a hidden network, manually enter its
SSID. If the device is configured to Create a Network, the SSID entered here will be the SSID of
the network created. When creating a network, the device will not create the network if the SSID
specified is the same as one that already exists in the area.
