Basic Settings
Configure the basic Wireless Network attributes for this Wireless Router.
SSID Name
. The SSID is the unique name shared between all devices in a wireless network. It is case-sensitive,
must not exceed 32 alphanumeric characters, and may be any keyboard character. Make sure this setting is the
same for all devices in your wireless network. The default SSID name is
linksys-n
.
Wireless Network Mode

B/G/N-Mixed
.
B-Only
: All the wireless client devices can be connected to the Wireless Router at Wireless-B data rates with
a maximum speed of 11Mbps.
G-Only
: Both Wireless-N and Wireless-G client devices can be connected at Wireless-G data rates with a
maximum speed of 54Mbps. Wireless-B clients cannot be connected in this mode.
N-Only
: Only Wireless-N client devices can be connected at Wireless-N data rates with a maximum speed of
300Mbps.
B/G-Mixed
: Both Wireless-B and Wireless-G client devices can be connected at their respective data rates.
Wireless-N devices can be connected at Wireless-G data rates.
G/N-Mixed
: Both Wireless-G and Wireless-N client devices can be connected at their respective data rates.
Wireless-B clients cannot be connected in this mode.
B/G/N-Mixed
: All the wireless client devices can be connected at their respective data rates in this mixed
mode.

when you click the
Save Settings
button, and it will take several seconds to scan through all the channels to find
the best channel. For the Wireless-N 40MHz channel option (see Wireless - Advanced Wireless Settings Tab), the
Wireless Router will automatically select the adjacent 20MHz channel to combine them into a wider channel.
SSID Broadcast
. This option allows the SSID to be broadcast on your network. You may want to enable this
function while configuring your network, but make sure that you disable it when you are finished. With this
enabled, someone could easily obtain the SSID information with site survey software or Windows XP and gain
unauthorized access to your network. Click
Enabled
to broadcast the SSID to all wireless devices in range. Click
Disabled
to increase network security and prevent the SSID from being seen on networked PCs. The default is
Enabled
in order to help users configure their network before use.
