STEP
5
In the
Wireless Band Selection
field, choose either
20MHz
or
20/40MHz
as the
wireless bandwidth on your network.
STEP
6
In the
Wireless Channel
field, choose the wireless channel from the drop-down
menu or choose
Auto
to let the system determine the optimal channel to use
based on the environmental noise levels for the available channels.
STEP
7
In the
AP Management VLAN
field, choose VLAN 1 if you are using the default
settings.
If you create additional VLANs, choose a value that corresponds with the VLAN
configured on other switches in the network. This is done for security purposes.
You might need to change the management VLAN to limit access to the
CVR100W’s Configuration Utility.
STEP
8
(Optional) In the
U-APSD (WMM Power Save)
field, check
Enable
to enable the
Unscheduled Automatic Power Save Delivery (U-APSD) feature, also referred to as
WMM Power Save, that allows the radio to conserve power.
U-APSD is a power saving scheme optimized for real-time applications, such as
VoIP, transferring full-duplex data over WLAN. By classifying outgoing IP traffic as
Voice data, these types of applications can increase battery life by approximately
25 percent and minimize transmit delays.

Configuring Wireless Security
For security purposes, we strongly recommend that you configure each SSID with
the highest level of security that is supported by the devices into your wireless
network. You can configure one of the following security modes for the wireless
network:
The
WEP
security mode offers weak security with a basic encryption method that
is not as secure as WPA. WEP may be required if your network devices do not
support WPA. If you do not have to use WEP, we recommend that you use WPA2.
The
WPA-Personal
,
WPA2-Personal
, and the
WPA2-Personal Mixed
security
modes offer strong security to replace WEP.
•
WPA-Personal:
WPA is part of the wireless security standard (802.11i)
standardized by the Wi-Fi Alliance and was intended as an intermediate
measure to take the place of WEP while the 802.11i standard was being
prepared. WPA-Personal supports Temporal Key Integrity Protocol (TKIP)
and Advanced Encryption Standard (AES) encryption.
•
WPA2-Personal:
(Recommended) WPA2 is the implementation of the
security standard specified in the final 802.11i standard. WPA2 supports
AES encryption and this option uses Pre-shared Key (PSK) for
authentication.
•
WPA2-Personal Mixed:
Allows both WPA and WPA2 clients to connect
simultaneously using PSK authentication. The personal authentication is the
PSK that is an alphanumeric passphrase shared with the wireless peer.
The
WPA-Enterprise
,
WPA2-Enterprise
, and the
WPA2-Enterprise Mixed
security modes allow you to use RADIUS server authentication.
•
WPA-Enterprise:
Allows you to use WPA with RADIUS server
authentication.
•
WPA2-Enterprise:
Allows you to use WPA2 with RADIUS server
authentication.
•
WPA2-Enterprise Mixed:
Allows both WPA and WPA2 clients to connect
simultaneously using RADIUS authentication.
To configure the security settings for a SSID:
STEP 1
In the
Wireless Table
(
Wireless
>
Basic Settings
), check the SSID that you want
to configure.
STEP
2
Click
Edit Security Mode
. The Security Settings page opens.

STEP

From the
Security Mode
menu, choose a security mode and specify the
corresponding settings. The following table lists the security settings for different
security modes.
Disabled
If you choose this option, any wireless device that is in range can connect to the
SSID. This is the default setting but not recommended.
This mode means that any data transferred to and from the SSID is not
encrypted. This security mode can be useful during initial network configuration
or for problem solving, but it is not recommended for regular use on the internal
network because it is not secure.
WEP
Authentication Type
Choose
Open System
or
Shared Key
if your network
administrator recommends this setting. If you are
unsure, select the default option (Open System).
In both cases, the wireless client must provide the
correct shared key (password) to access the wireless
network.
Encryption
Choose the encryption type:
•
10/64-bit (10 hex digits):
Provides a 40-bit key.
•
26/128-bit (26 hex digits):
Provides a 104-bit
key, which offers stronger encryption, making
the key more difficult to crack. We recommend
128-bit encryption.
Passphrase
(Optional) Enter an alphanumeric phrase (longer than
eight characters for optimal security) and click
Generate
to generate four unique WEP keys in the
Key1-4
fields below.
If you want to provide your own key, enter it directly in
the
Key 1
field (recommended). The length of the key
should be 5 ASCII characters (or 10 hexadecimal
characters) for 64-bit WEP and 13 ASCII characters (or
26 hexadecimal characters) for 128-bit WEP. Valid
hexadecimal characters are 0 to 9 and A to F.

options:
•
TKIP/AES:
Choose
TKIP/AES
to ensure
compatibility with older wireless devices that
may not support AES.
•
AES:
This option is more secure.
WPA2-Personal always uses AES for data encryption.
WPA2-Personal Mixed automatically uses TKIP or AES
for data encryption.
Security Key
Enter an alphanumeric phrase (8 to 63 ASCII
characters or 64 hexadecimal digits).
Show Password
Check to show the password in plaintext.
Key Renewal
Enter the duration of time (600 to 7200 seconds)
between key renewals. The default value is 3600.

Encryption
For WPA-Enterprise, choose one of the following
options:
•
TKIP/AES:
Choose
TKIP/AES
to ensure
compatibility with older wireless devices that
may not support AES.
•
AES:
This option is more secure.
WPA2-Enterprise always uses AES for data
encryption.
WPA2-Enterprise Mixed automatically uses TKIP or
AES for data encryption.
RADIUS Server
Enter the IP address of the RADIUS server.
RADIUS Port
Enter the port used to access the RADIUS server.
