Wireless Settings
This page allows you to configure and secure your wireless network. You will need the following information to configure your wireless access point: types of devices that are expected to access the wireless network, the region you are in, and the security options you would like to use for securing your wireless network.
Wireless Network
v Name (SSID): the name or SSID (service set identifier) is the unique name of the wireless network that is to be created. Computers and devices communicating via this wireless gateway will choose the SSID configured in this field.
v Region: select the region in which the wireless gateway is operating. If this is unknown, or not in the list, select none (the channel will be auto-detected in this case). The region selection automatically shortlists the frequency channels (in the Channel dropdown list) available for this wireless gateway. Selecting a new region and clicking Apply will require a reboot to set the configuration.
For Europe there are 2 region codes listed:
Europe(20Mhz) - This selection limits the 11na 5Ghz mode operation to 20Mhz only. Select this, if your country does not support 40, 20/40 operations in
5Ghz mode.
Europe(40Mhz) - This selection allows 40, 20/40 mode operations in 11na 5Ghz mode. Select this if your country supports 40, 20/40 operations in 5Ghz mode.
For further clarifications on what channels are allowed in your country please check with your country's regulatory body. You can also check http://en.wikipedia.org/wiki/IEEE_802.11, http://www.wi-fi.org/, http://ieee802.org/11/ for additional details.
v Channel Spacing: The 802.11n standard allows you to set the channel spacing (or bonding) for wireless traffic between the access point and client. Select between 40 MHz (maximum spacing to minimize packet collisions) and 20 MHz (more efficient when many clients are in the wireless network). The 20/40 MHz option provides support for both spacing based on the environment and client capabilities. 20 MHz is the default channel spacing.
v Mode: This selects the 802.11 modulation technique. This device supports 802.11a, 802.11b, 802.11g, 802.11ng and 802.11na modes. Select g only if all devices in the wireless network can support 802.11g mode only (i.e 54 Mbit/sec maximum); select b only if other devices and computers in the network can only support the 11 Mbit/sec maximum data rate provided by 802.11b. Select a only if all devices in the wireless network will connect via 802.11a (5.4 GHz band) only. Select g and b if there will be some devices in this wireless network that will use 802.11g and others that will use 802.11b. Select ng mode if there are clients in the network that support 802.11n modulation speeds; this mode also supports legacy 802.11b and 802.11g clients. To support 802.11a and 802.11n clients concurrently, select na mode; this mode will NOT support 802.11b or 802.11g clients.
v Channel: based on the region selected above, the available channels are presented in a dropdown list. The Auto channel  selects the best channel available based on the signal strength. The Current Channel No: is the current channel frequency used by the wireless gateway.
Wireless Access Point
v Select Enable Wireless Access Point to create a wireless network where computers and other devices communicate with each other by first going through this wireless gateway. Also known as Infrastructure Mode, selecting this box allows multiple devices in the wireless network to access the WAN network and other LAN devices through this wireless gateway.
v Select Allow Broadcast of Name (SSID) to display the name of this wireless network to all supported devices within range. These devices will still be protected by the selected wireless security options to access the network. To hide the name of the wireless network from the public uncheck this box. In this case, a wireless client device needs to know the exact SSID to connect to the wireless gateway.
Wireless Security Type
Selecting some form wireless security is essential to securing your wireless network and the data that passes through it. To create a public “open” network, select none and check the box to Allow Broadcast of Name (SSID) to allow public, unauthenticated devices to access the internet and wireless network through this wireless gateway.
v WEP (Wired Equivalent Privacy): select this option if all devices in the network are configured with a static key, also known as a pre-shared key. The WEP settings (Authentication, Encryption, and passphrase) are made available in the WEP section of this page. This security option should only be chosen if all networked computers do not support the other options, since this is a weak security mechanism.
v WPA (Wi-Fi Protected Access): For stronger wireless security. This authentication and data encryption option will require choosing between Personal mode with a pre-shared key (PSK) , using TKIP or AES encryption and Enterprise mode with RADIUS, using TKIP encryption. The corresponding fields in subsequent boxes are enabled based on the authentication and encryption pair selected.
v WPA2: this security type uses AES encryption on either PSK or RADIUS Server authentication.
v WPA and WPA2: This uses both encryption algorithms, TKIP and AES. WPA clients will use TKIP and WPA2 clients will use AES encryption algorithms.
WEP
Selecting WEP in the Wireless Security Type box requires a unique static key to be used in the computers or devices that wish to access this secured wireless network. This is generated by filling in the following fields:
v Authentication: select between Automatic, Open System, or Shared Key schemes
v Encryption: select the encryption type: 64 WEP, 128 WEP, or 152 WEP. The larger size keys provide stronger encryption, thus making the key more difficult to crack (e.g. 64 WEP has a 40 bit key which is less secure than the 128 WEP which has a 104 bit key).
v WEP Passphrase: choose any alphanumeric phrase and click Generate Key to generate 4 unique WEP keys. Choose one of the keys to be used for authentication. The selected key must be used by the wireless clients to connect to this router.
PSK Settings
When using WPA, PSK (Pre-shared Key) encryption is an option.
v Passphrase: an 8 to 63 character alphanumeric pass code is required.
v Key Lifetime: This setting determines how often the encryption key is changed; shorter periods are more secure but may slow down overall authentication times.
Radius Server Settings
If a RADIUS (Remote Authentication Dial In User Service) Server is to be used for WPA and/or WPA2 authentication, then the Server Name or IP Address is required to identify the server.
v Radius Port: the port number used to connect to the RADIUS Server
v Shared Key: enter the shared key that allows this wireless gateway to log into the RADIUS server specified above; it must match the key on the RADIUS Server.
Click Apply to save the changes.
Click Reset to revert to the previous settings.
