ESSID: (Extended Service Set Identifier) The ESSID is a unique name that identifies a
wireless network. This value is case sensitive, and may be up to 32 alphanumeric
characters.
Broadcast ESSID: Enables broadcasting of the ESSID. This makes this wireless
network visible to clients that are scanning for wireless networks. Choosing not to
broadcast the ESSID should not be considered a security measure; clients can still
connect if they know the ESSID, and it is possible for network sniffers to read the ESSID
from other clients.
Channel/Frequency: Select the operating frequency or channel for the wireless network.
Changing to a different channel may give better performance if there is interference from
another access point.
Bridge Between Clients: This setting enables the access point to forward packets
between clients at the wireless level, i.e. wireless clients are able to "see" each other.
This means that packets between wireless clients are not restricted by the firewall. Note
that if you disable this setting, but you still want to allow access between clients in the
firewall, you usually also need to configure each client to route to other clients via the
access point.
Wireless security
Encryption and authentication settings for your wireless network are configured under
Access Point. Fields vary based on the security method you choose.
