Manage the Basic WiFi Settings and WiFi Security of the Main
Network
The modem router comes with preset security. This means that the WiFi network name (SSID), network key
(password), and security option (encryption protocol) are preset in the factory. The preset SSID and password are
uniquely generated for every device to protect and maximize your WiFi security.You can find the preset SSID and
password on the product label (see
Bottom Panel Product Label
on page 17).
IMPORTANT:
We recommend that you do
not
change your preset security settings. If you do decide
to change your preset security settings, make a note of the new settings and store the
note in a safe place where you can easily find it.
View or Change the Basic WiFi Settings
You can view or change the basic WiFi settings and WiFi security. The modem router simultaneously supports the
2.4 GHz band for 802.11b/g/n devices and the 5 GHz band for 802.11a/n/ac devices.
If you do decide to change the WiFi settings of the modem router’s main network, use a wired
connection to avoid being disconnected when the new WiFi settings take effect.

Wireless Network (2.4GHz b/g/n)
By default, the modem router broadcasts its SSID so that WiFi stations can detect the WiFi name
(SSID) in their scanned network lists. To turn off the SSID broadcast, clear the
Enable SSID
Broadcast
check box.Turning off the SSID broadcast provides additional WiFi security, but users
must know the SSID to be able to join the WiFi network of the modem router.
Enable SSID Broadcast
The SSID is the WiFi network name. If you did not change the SSID, the default SSID displays.
The default SSID is also printed on the product label (see
Bottom Panel Product Label
on page
17).
We recommend that you do not change the default SSID. If you must change
the SSID, enter a 32-character (maximum), case-sensitive name in this field.
Note
Name (SSID)
From the
Channel
menu, select
Auto
for automatic channel selection or select an individual
channel. The default selection is
Auto
.
In some regions, not all channels are available. Do not change the channel
unless you experience interference (shown by lost connections or slow data
transfers). If this situation occurs, experiment with different channels to see
which is the best.
Note
If you use multiple WiFi access points (APs), reduce interference by selecting
different channels for adjacent APs. We recommend a channel spacing of four
channels between adjacent APs (for example, use Channels 1 and 5, or 6 and
10).
