4.10 Certificate Management

A digital certificate works as an electronic ID, which is issued by a certification authority

(CA). It contains information such as your name, a serial number, expiration dates etc., and the

digital signature of the certificate-issuing authority so that a recipient can verify that the

certificate is real. Here Vigor router support digital certificates conforming to standard X.509.

Any entity wants to utilize digital certificates should first request a certificate issued by a CA

server. It should also retrieve certificates of other trusted CA servers so it can authenticate the

peer with certificates issued by those trusted CA servers.

Here you can manage generate and manage the local digital certificates, and set trusted CA

certificates. Remember to adjust the time of Vigor router before using the certificate so that

you can get the correct valid period of certificate.

Below shows the menu items for Certificate Management.

4.11 Wireless LAN

This function is used for “n” models only.

4.11.1 Basic Concepts

Over recent years, the market for wireless communications has enjoyed tremendous growth.

Wireless technology now reaches or is capable of reaching virtually every location on the

surface of the earth. Hundreds of millions of people exchange information every day via

wireless communication products. The Vigor “n” model, a.k.a. Vigor wireless router, is

designed for maximum flexibility and efficiency of a small office/home. Any authorized staff

can bring a built-in WLAN client PDA or notebook into a meeting room for conference

without laying a clot of LAN cable or drilling holes everywhere. Wireless LAN enables high

mobility so WLAN users can simultaneously access all LAN facilities just like on a wired

LAN as well as Internet access.

The Vigor wireless routers are equipped with a wireless LAN interface compliant with the

standard IEEE 802.11n draft 2 protocol. To boost its performance further, the Vigor Router is

also loaded with advanced wireless technology to lift up data rate up to 300 Mbps*. Hence,

you can finally smoothly enjoy stream music and video.

Note

:

*

The actual data throughput will vary according to the network conditions and

environmental factors, including volume of network traffic, network overhead and

building materials.

In an Infrastructure Mode of wireless network, Vigor wireless router plays a role as an Access

Point (AP) connecting to lots of wireless clients or Stations (STA). All the STAs will share the

same Internet connection via Vigor wireless router. The

General Settings

will set up the

information of this wireless network, including its SSID as identification, located channel etc.

Multiple SSIDs

Vigor router supports four SSID settings for wireless connections. Each SSID can be defined

with different name and download/upload rate for selecting by stations connected to the router

wirelessly.

Security Overview

Real-time Hardware Encryption:

Vigor Router is equipped with a hardware AES encryption

engine so it can apply the highest protection to your data without influencing user experience.

Complete Security Standard Selection:

To ensure the security and privacy of your wireless

communication, we provide several prevailing standards on market.

WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via

radio using either a 64-bit or 128-bit key. Usually access point will preset a set of four keys

and it will communicate with each station using only one out of the four keys.

WPA (Wi-Fi Protected Access), the most dominating security mechanism in industry, is

separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK), and

WPA-Enterprise or called WPA/802.1x.

In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA

applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies AES.

The WPA-Enterprise combines not only encryption but also authentication.

Since WEP has been proved vulnerable, you may consider using WPA for the most secure

connection. You should select the appropriate security mechanism according to your needs.

No matter which security suite you select, they all will enhance the over-the-air data

protection and /or privacy on your wireless network. The Vigor wireless router is very flexible

and can support multiple secure connections with both WEP and WPA at the same time.

Separate the Wireless and the Wired LAN- WLAN Isolation

enables you to isolate your

wireless LAN from wired LAN for either quarantine or limit access reasons. To isolate means

neither of the parties can access each other. To elaborate an example for business use, you

may set up a wireless LAN for visitors only so they can connect to Internet without hassle of
