6.7 Interface Grouping

Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button removes mapping groups, returning the ungrouped interfaces to the Default group. Only the default group has an IP interface.

To add an Interface Group, click the Add button. The following screen will appear. It lists the available and grouped interfaces. Follow the instructions shown onscreen.

Automatically Add Clients With Following DHCP Vendor IDs:

Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when Interface Grouping is enabled.

For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are ETH1, ETH2, ETH3, and ETH4.

The Interface Grouping configuration will be:

1. Default: ETH1, ETH2, ETH3, and ETH4.

2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".

If the onboard DHCP server is running on "Default" and the remote DHCP server is running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33).

If a set-top box is connected to ETH1 and sends a DHCP request with vendor ID "Video", the local DHCP server will forward this request to the remote DHCP server. The Interface Grouping configuration will automatically change to the following:

1. Default: ETH2, ETH3, and ETH4

2. Video: nas_0_36, nas_0_37, nas_0_38, and ETH1

SSID

[1-32 characters]

Sets the wireless network name. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access.

BSSID The BSSID is a 48-bit identity used to identify a particular BSS

(Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point); and in Independent BSS or ad hoc networks, the BSSID is generated randomly.

Country A drop-down menu that permits worldwide and specific national

settings. Local regulations limit channel range: US= worldwide, Japan=1-14, Jordan= 10-13, Israel= 1-13

Max Clients The maximum number of clients that can access the router.

6.12.2 Security

The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface.

Click Apply/Save to implement new configuration settings.

WIRELESS SECURITY

Setup requires that the user configure these settings using the Web User Interface (see the table below).

Select SSID

Select the wireless network name from the drop-down box. SSID stands for Service Set Identifier. All stations must be confi WLAN. If the SSID does not match, that client will not be granted access.

Network Authentication

This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified.

Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below.

106

The settings for WPA authentication are shown below.

The settings for WPA-PSK authentication are shown next.

107

WEP Encryption

This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined althou Network Key list box to select the appropriate network key.

Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdroppin case, the capture of wireless network traffic. When data encryption is enabled, secret shared encryption keys are used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers.

Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel.

Encryption Strength

This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a are considerably more difficult to crack. Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data.

6.12.3 WPS

Wi-Fi Protected Setup (WPS) is an industry standard that simplifies wireless security setup for certified network devices. Every WPS certified device has both a PIN number and a push button, located on the device or accessed through device software. The AR-5312u has a WPS button on the device.

Devices with the WPS logo (shown here) support WPS. If the WPS logo is not present on your device it still may support WPS, in this case, check the device documentation for the phrase “Wi-Fi Protected Setup”.

NOTE: WPS is only available in Open, WPA-PSK, WPA2-PSK and Mixed

WPA2/WPA-PSK network authentication modes. Other authentication modes do not use WPS so they must be configured manually.

To configure security settings with WPS, follow the procedures below. You must choose either the Push-Button or PIN configuration method for Steps 6 and 7.

I. Setup

Step 1: Enable WPS by selecting Enabled from the drop down list box shown.

Step 2: Set the WPS AP Mode. Configured is used when the AR-5312u will assign

security settings to clients. Unconfigured is used when an external client assigns security settings to the AR-5312u.

NOTES: You r client may or may not have the ability to provide security settings to

the AR-5312u. If it does not, then you must set the WPS AP mode to Configured. Consult the device documentation to check its capabilities.

In addition, using Windows 7, you can add an external registrar using the

Config AP button (Appendix F - WPS OPERATION has detailed instructions).

109

II. NETWORK AUTHENTICATION

Step 3: Select Open, WPA-PSK, WPA2-PSK, or Mixed WPA2/WPA-PSK network

authentication mode from the Manual Setup AP section of the Wireless Security screen. The example below shows WPA2-PSK mode.

Step 4: For the Pre-Shared Key (PSK) modes, enter a WPA Pre-Shared Key. You

will see the following dialog box if the Key is too short or too long.

Step 5: Click the Apply/Save button at the bottom of the screen.

IIIa. PUSH-BUTTON CONFIGURATION

The WPS push-button configuration provides a semi-automated configuration method. The WPS button on the rear panel of the router can be used for this purpose or the Web User Interface (WUI) can be used exclusively.

The WPS push-button configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.

110

NOTE: The wireless AP on the router searches for 2 minutes. If the router stops

searching before you complete Step 7, return to Step 6.

Step 6: Press WPS button

Press the WPS button on the front panel of the router. The WPS LED will

blink to show that the router has begun searching for the client.

Step 7: Go to your WPS wireless client and activate the push-button function. A typical WPS client screenshot is shown below as an example.

Now go to Step 8 (part IV. Check Connection) to check the WPS connection.

IIIb. WPS – PIN CONFIGURATION

Using this method, security settings are configured with a personal identification number (PIN). The PIN can be found on the device itself or within the software. The PIN may be generated randomly in the latter case. To obtain a PIN number for your client, check the device documentation for specific instructions.

The WPS PIN configuration is described in the procedure below. It is assumed that the Wireless function is Enabled and that the router is configured as the Wireless Access Point (AP) of your wireless LAN. In addition, the wireless client must also be configured correctly and turned on, with WPS function enabled.

NOTE: Unlike the push-button method, the pin method has no set time limit.

This means that the router will continue searching until it finds a client.

Step 6: Select the PIN radio button in the WSC Setup section of the Wireless

Security screen, as shown in A or B below, and then click the appropriate button based on the WSC AP mode selected in step 2.

A - For Configured mode, click the Add Enrollee button.

Enter STA PIN: a Personal Identification Number (PIN) has to be read from either

a sticker or the display on the new wireless device. This PIN must then be inputted at representing the network, usually the Access Point of the network.

B - For Unconfigured mode, click the Config AP button.

111

Step 7: Activate the PIN function on the wireless client. For Configured mode,

the client must be configured as an Enrollee. For Unconfigured mode, the client must be configured as the Registrar. This is different from the External Registrar function provided in Windows Vista.

The figure below provides an example of a WPS client PIN function in-progress.

Now go to Step 8 (part IV. Check Connection) to check the WPS connection.

IV. CHECK CONNECTION

Step 8: If the WPS setup method was successful, you will be able access the

wireless AP from the client. The client software should show the status. The example below shows that the connection established successfully.

You can also double-click the Wireless Network Connection icon from the

Network Connections window (or the system tray) to confirm the status of the new connection.

Bridge Restrict Selecting Disabled disables wireless bridge restriction, which

means that any wireless bridge will be granted access. Selecting Enabled or Enabled (Scan) enables wireless bridge restriction. Only those bridges selected in the Remote Bridges list will be granted access. Click Refresh to update the station list when Bridge Restrict is enabled.

115

6.12.6 Advanced

The Advanced screen allows you to configure advanced features of the wireless LAN interface. You can select a particular channel on which to operate, force the transmission rate to a particular speed, set the fragmentation threshold, set the RTS threshold, set the wakeup interval for clients in power-save mode, set the beacon interval for the access point, set XPress mode and set whether short or long preambles are used. Click Apply/Save to set new advanced wireless options.

Field Description

Band Set to 2.4 GHz for compatibility with IEEE 802.11x

standards. The new amendment allows IEEE 802.11n units to fall back to slower speeds so that legacy IEEE

802.11x devices can coexist in the same network. IEEE

802.11g creates data-rate parity at 2.4 GHz with the IEEE

802.11a standard, which has a 54 Mbps rate at 5 GHz. (IEEE 802.11a has other differences compared to IEEE

802.11b or g, such as offering more channels.)
