3.2.2.1 Wireless AP only

When you are in the AP only mode, you can set up the basic wireless functions as below:

AP setting:

SSID: The SSID identifies a specific wireless LAN. Before associating with a particular wireless LAN, a station must have the same SSID as the access point. The default SSID setting is “Conceptronic”. NOTE: Please

DO NOT set the same SSID with your current wireless network.

Channel: The radio channel number. The default channel is “1”. NOTE:

Please DO NOT set the same Channel with your current wireless

network.

Authentication: Authentication ensures that digital data transmissions are delivered to the intended receiver. This option enables you to set the authentication method for various encryption schemes for the selected AP.

Open or shared WEP Encryption: Select “64” or “128” bits for encryption method to protect your data by encrypting it. The WEP key can be 5~13 ASII characters or 10~26 hexadecimal characters based on

37

whether you select 64 bit or 128 bit WEP encryption.

802.1X: IEEE802.1x authentication can be done by using an external

RADIUS server.

Please input the IP address of RADIUS server and Shared Secret.

WPA-PSK: AP and Client need to use identical Pre-shared key (PSK).

Please input 64 Hex key (0~F) or 8~63 characters in ASCII Type.

Note. This device only supports WPA version 1.

WPA: WPA applies IEEE802.1x and Extensible Authentication Protocol

(EAP) to authenticate wireless clients using an external RADIUS server.

Please input the IP address of RADIUS and Shared Secret.

38

Advance Setting:

Wireless mode: 11b/g mixed can let 11g or 11b computers both exist on the network, but the speed will be reduced. Select 11g only for maximum speed, but no 11b users will be allowed on the network.

Beacon interval: This represents the amount of time between beacon transmissions. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. Beacons are packets sent by an Access Point to synchronize a wireless network. Specify a Beacon interval value between 1 and 1000.

The default value is set to 100 milliseconds.

RTS Threshold: The RTS threshold specifies the packet size of an RTS transmission. This helps control traffic flow through an access point, especially one with many clients. The setting value range is from 1 to

2347, and default value is set to 2347.

Fragmentation: In a network, the maximum size or length of a fragment is determined by the protocol used to transport the data. This value should remain at its default setting of 2346. If you experience a high

39

packet error rate, you may slightly increase your "Fragmentation" value within the value range of 256 to 2346, even number only. Setting the

Fragmentation value too low may result in poor performance.

DTM interval: A Delivery Traffic Indication Message (DTIM) is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next

DTIM with a DTIM Interval value. AP clients hear the beacons and awaken to receive the broadcast and multicast messages. Enter a value from 1 to 255 for DTIM. The default value for DTIM interval is set to 3.

Preamble Type: The Preamble Type defines the length of the CRC (Cyclic

Redundancy Check) block for communication between the Access Point and roaming wireless adapters.

SSID Broadcast: Enable or Disable a SSID broadcast. When enabled, the

SSID of the CHD2WLANU is sent to wireless enabled devices on the LAN.

Press “Next” button, you could see the Wireless MAC Filtering setting.

40

The default setting is “Disable Mac filtering”, every wireless client could connect to this AP. When you select “ALL accept”, the wireless clients with the

MAC addresses you enter bellow will be accepted to connect to this AP, the others will be rejected. When you select “ALL Reject”, the wireless clients with the MAC addresses you enter bellow will be rejected to connect to this AP, the others will be accepted.

After press “Next” button, the CHD2WLANU would show you this page about the wireless settings you have done.

How to setup wireless function?

1. How can I use the wireless function?

A: Generally speaking, there are four modes to setup in this device. The common function is “AP mode”. The user can make this device as Wireless

AP device as follows:

First, the wireless client sets up the same SSID with the CHD2WLANU and get

IP from Router. Then Wireless client can associate the network or roam

Internet via Router.

Wireless Client Mode: First, please configure the wireless setting of the

CHD2WLANU via wire. Then use Scan AP of AP-List and join it. Plug up the cable form the CHD2WLANU. The client from LAN can use “Configure” utility to Query.

56

WDS only mode: WDS Wireless Distribution system. This device also supports this function. How to configure this in your circumstance? The below Figure1 is for the reference. First, check which channel you want to use. For example, channel 10. Scan other AP which channel is 10 and supports WDS function. Second, add the wireless MAC address of the

CHD2WLANU in this Wireless Router # 2. (Figure2). And use Scan AP to find the wireless which SSID is “WR-2” and join it in the list. Third, if it is normal,

LAN-Host#1 can find the devices, like Wireless Router #2 and LAN-Host#2.

Figure2:

WDS Hybrid mode: This device also supports WDS and AP mode at the same time. How to configure this in your circumstance? The below figure is for the reference.

SSID: Conceptronic

For the setting of WDS, please refer to the above WDS only mode.

For AP setting, please refer to the AP mode.

2. How to configure 802.1x or WPA with Radius server?

Equipment Details

PC1:

Microsoft Windows XP Professional without Service Pack 1.

D-Link DWL-650+ wireless LAN adapter

Driver version: 3.0.5.0 (Driver date: 03.05.2003)

PC2:

Microsoft Windows XP Professional with Service Pack 1a.

Z-Com XI-725 wireless LAN USB adapter

Driver version: 1.7.29.0 (Driver date: 10.20.2001)

Authentication Server: Windows 2000 RADIUS server with Service Pack 3 and HotFix Q313664.

Note. Windows 2000 RADIUS server only supports PEAP after upgrade to service pack 3 and HotFix Q313664 (You can get more information from

http://support.microsoft.com/default.aspx?scid=kb; en-us;313664)

DUT Configuration:

1. Enable DHCP server.

2. WAN setting: static IP address.

3. LAN IP address: 192.168.123.254/24.

59

4. Set RADIUS server IP.

5. Set RADIUS server shared key.

6. Configure WEP key and 802.1X setting.

The following test will use the inbuilt 802.1X authentication method such as EAP_TLS, PEAP_CHAPv2 (Windows XP with SP1 only), and PEAP_TLS

(Windows XP with SP1 only) using the Smart Card or other Certificate of the Windows XP Professional.

DUT and Windows 2000 RADIUS Server Setup

1. Setup Windows 2000 RADIUS Server. We have to change authentication method to MD5_Challenge or using smart card or other certificate on

RADIUS server according to the test condition.

2. Setup DUT

Enable the 802.1X (check the “Enable checkbox“).

Enter the RADIUS server IP.

Enter the shared key. (The key shared by the RADIUS server and

DUT).

We will change 802.1X encryption key length to fit the variable test condition.

3. Setup Network adapter on PC

Choose the IEEE 802.1X as the authentication method. (Figure

2)

Note. Figure 2 is a setting picture of Windows XP without service pack

1. If users upgrade to service pack 1, then they can’t see

MD5-Challenge from EAP type list any more, but they will get a new

Protected EAP (PEAP) option.

Choose MD5-Challenge or Smart Card or other Certificate as the

EAP type.

If choosing use smart card or the certificate as the EAP type, we select to use certificate on this computer.

We will change EAP type to fit the variable test condition.

60

Figure 2: Enable IEEE 802.1X access control

Windows 2000 RADIUS server Authentication testing:

1. DUT authenticate PC1 using certificate. (PC2 follows the same test procedures.)

2. Download and install the certificate on PC1. (Figure 4)

3. PC1 choose the SSID of DUT as the Access Point.

4. Set authentication type of wireless client and RADIUS server both to

61

EAP_TLS.

5. Disable the wireless connection and enable again.

6. The DUT will send the user's certificate to the RADIUS server, and then send the message of authentication result to PC1. (Figure 5)

7. Windows XP will prompt that the authentication process is success or fail and end the authentication procedure. (Figure 6)

8. Terminate the test steps when PC1 get dynamic IP and PING remote host successfully.

Figure 5: Authenticating

Figure 6: Authentication success

DUT authenticate PC2 using PEAP-TLS.

1. PC2 choose the SSID of DUT as the Access Point.

2. Set authentication type of wireless client and RADIUS server both to

PEAP_TLS.

3. Disable the wireless connection and enable again.

4. The DUT will send the user's certificate to the RADIUS server, and then send the message of authentication result to PC2.

5. Windows XP will prompt that the authentication process is success or fail and end the authentication procedure.

6. Terminate the test steps when PC2 get dynamic IP and PING remote host successfully.

Problems of security level

1. Why can’t I access the file from my places after enabling Security Level?

A:

Sometimes, I can not access the folders via my places after enabling Security

Level, like below:

If the user sees the warning message, please restart windows and try it again.

But there are some situations that the users can not access this folder if even they input correct the account and password as below:

Situation 1: The users can access the files or folders before the CHD2WLANU is not enabled “security Level”. But when the CHD2WLANU is enabled it, the authorization users can not login by inputting the account and password.

Please restart your window OS and It can be accessed.

Situation 2: Change the account and password of the CHD2WLANU. In brief, the users have some Limit authority to access the folders, but if someone changes account and password this time, other authorization users can not access at all. Please restart your window OS.

64

This is because the windows will cache some records so that the settings can not work immediately and the users have no idea to restart the device.

2. How do I configure the authority of file-shared by my places and ftp service?

A: Take an example as follows:

First, Set account 123 and password 12345.

Then Click Configure the shared directory.

Create two folders. One is “read”, and the other is “write”. The authority is as follows:

65

Then click the User Access Configuration and save “Security Level”.

66

Use search the CHD2WLANU hostname, if you can not access the directory

Storage”.

Then you will find the CHD2WLANU and will find some folders, like read, write and Storage.

67

If you are a guest and you just can copy the files in the folder ”read” and copy, move and delete the files or folders in the folder ”write”.

But if you are an Authorization user. Anyway you directly click the folders

read and write”. However, you just have the same limits of authority with guests. Please login the folder “Storage” to begin.

This product also defines two user-level(Guest and Authorization users) to share files by ftp service.

The configuration is the same with above. There are two folders to share.

If the users use guest to login ftp service, he just accesses read or write folders. Or login as Authorization users, he can access all.
