Parental Control Time of Day Access Policy Page
This
page allows you to block all Internet traffic to and from specified devices on your
SBG941 network based on the day and time settings you specify. You can set policies to
block Internet traffic for the entire day or just certain time periods within each day for
specific users. You can add up to 30 eight-character categories (filter names) with
different day and time settings. You enter a name for each time filter in the
Add New
Policy
field. Any time filter for Internet access can be enabled or disabled at any time.
The time filters for limited Internet access are applied for each user in the
Time Access
Rule
field on the
Parental Control User Setup Page
.
After each category change is made, click
Apply
at the bottom of the page to store and
activate the settings. These same category names for blocking profiles show up in the
Parental Control section on the User Setup page in the “Time Access Rules” section. On
that page, each user is assigned up to four of these categories simultaneously.

Parental Control Event Log Page
This page displays the Parental Control event log report. The event log is a running list of
the last 30 Parental Control access violations, which include the following items on
Internet traffic:
If the user’s Internet access is blocked (time filter)
If a blocked keyword is detected in the URL
If a blocked domain is detected in the URL
If the online lookup service detects that the URL falls under a blocked category

Wireless Pages
The SBG941 Wireless Pages allow you to configure your wireless LAN (WLAN). WPA or
WPA2 encryption provides higher security than WEP encryption, but older wireless client
cards may not support the newer WPA or WPA2 encryption methods.
Wireless 802.11 Radio Page
This page allows you to configure the Wireless Radio parameters, including the current
country and channel number.
Field Descriptions for the Wireless 802.11 Radio Page
Field
Description
Wireless Interfaces
Shows the MAC address of the installed wireless card (not
configurable).
Wireless
Shows if the wireless network is enabled or disabled.
Country
Restricts the channel set based on the country’s regulatory
requirements. This is a display-only field.
Output Power
Sets a percentage of the output power of the hardware’s maximum
capability.
Channel
Selects the channel for access point (AP) operation. The list of
available channels depends on the designated country.
For this field, the channel selected on the wireless clients on your
WLAN must be the same as the one selected on the SBG941.

Wireless 802.11 Primary Network Page
This page allows you to configure the Primary wireless network.
Field Descriptions for the Wireless 802.11 Primary Network Page
Field
Description
Primary Network
When
Enabled
, beacon frames are transmitted with the
Primary Network SSID.
Network Name (SSID)
Sets the Network Name (also known as SSID) of the Primary
wireless network. This is a 1-32 ASCII character string.
Closed Network
With a closed network, users type the SSID into the client
application instead of selecting the SSID from a list. This
feature makes it slightly more difficult for the user to gain
access.
WPA
Enables or disables Wi-Fi Protected Access encryption.
WPA-PSK
Enables or disables a local WPA pre-shared key passphrase.
WPA2
Enables or disables Wi-Fi Protected Access 2 encryption.
WPA2-PSK
Enables or disables a local WPA2 pre-shared key passphrase.

WPA/WPA2 Encryption
When using WPA or WPA2 authentication, these WPA
encryption modes can be set: TKIP, AES, or TKIP + AES. AES
(Advanced Encryption Standard) provides the strongest
encryption, while TKIP (Temporal Key Integrity Protocol)
provides strong encryption with improved compatibility. The
TKIP + AES mode allows both TKIP and AES-capable clients to
connect.
WPA Pre-Shared Key
Show Key
Sets the WPA Pre-Shared Key (PSK). This is either an 8-63
ASCII character string or a 64-digit hex number. This is
specified when the Network Authentication method is WPA-
PSK.
Show Key
- When selected, the WPA Pre-Shared Key is
displayed.
RADIUS Server
Sets the RADIUS server IP address to use for client
authentication using the dotted-decimal format
(xxx.xxx.xxx.xxx).
RADIUS Port
Sets the UDP port number of the RADIUS server. The default
is 1812.
RADIUS Key
Sets the shared secret for the RADIUS connection. The key is
a 0 to 255 character ASCII string.
Group Key Rotation Interval
Sets the WPA Group Rekey Interval in seconds. Set to zero to
disable periodic rekeying.
WPA/WPA2 Re-auth Interval
The re-authentication interval is the amount of time the
wireless router can wait before re-establishing authentication
with the CPE.
WEP Encryption
WEP Encryption enables or disables Wired Equivalent Privacy
encryption.
Shared Key Authentication
The WEP protocol uses the Shared Key Authentication
protocol where the CPE sends an authentication request to
the access point. Then the access point sends a challenge text
to the CPE.
The CPE uses either the 64-bit or 128-bit key to encrypt the
challenge text and sends the encrypted text to the access
point. The access point decrypts the encrypted text and then
compares the decrypted message with the original challenge
text. If they are the same, the access point lets the CPE
connect; if it doesn’t match, then the access point does not let
the CPE connect.
