Do not modify default value if you don’t know what it is, default value is 3. Data Rate (5): Set the wireless data transfer rate to a certain value. Since most of wireless devices will negotiate with each other and pick a proper data transfer rate automatically, it’s not necessary to change this value unless you know what will happen after modification.
Unless you‟re using this wireless router in a really big space, you may not have to set output power to 100%. This will enhance security (malicious / unknown users in distance will not be able to reach your wireless router). WMM (12): The short of Wi-Fi MultiMedia, it will enhance the data transfer performance of multimedia contents when they‟re being transferred over wireless network.
2-7-3 Wireless Security It’s very important to set wireless security settings properly! If you don‟t, hackers and malicious users can reach your network and valuable data without your consent and this will cause serious security problem. To set wireless security settings, Please click „2.
2-7-3-2 WEP - Wired Equivalent Privacy When you select this mode, the wireless router will use WEP encryption, and the following setup menu will be shown on your web browser: 1 2 3 4 5 6 7 8 9 10 Here are descriptions of every setup items: Key Length (2): There are two types of WEP key length: 64-bit and 128-bit. Using „128-bit‟ is safer than ‟64-bit‟, but will reduce some data transfer performance. Key Format (3): There are two types of key format: ASCII and Hex.
displayed at „Key Format‟ field. You can use any alphanumerical characters (0-9, a-z, and A-Z) if you select „ASCII‟ key format, and if you select „Hex‟ as key format, you can use characters 0-9, a-f, and A-F. You must enter at least one encryption key here, and if you entered multiple WEP keys, they should not be same with each other. Enable 802.1x IEEE 802.1x is an authentication protocol.
TIPS: Some examples of WEP key (Don’t use those examples; use the one of your own!): ASCII (5 characters): pilot phone 23561 2Hyux #@xmL ASCII (13 characters): digitalFAMILY 82Jh26xHy3m&n Hex (10 characters): 287d2aa732 1152dabc85 Hex (26 characters): 9284bcda8427c9e036f7abcd84 To improve security level, do not use those words which can be found in a dictionary or too easy to remember! (‘pilot’ and ‘phone’ listed above are bad examples; just intended to show you how a WEP key look like).
2-7-3-3 Wi-Fi Protected Access (WPA): When you select this mode, the wireless router will use WPA encryption, and the following setup menu will be shown on your web browser: 1 2 3 4 5 Here are descriptions of every setup items: WPA Unicast Cipher Suite (2): Pre-shared Key Format (3): Pre-shared Key (4): Please select a type of WPA cipher suite.

2-7-5 Wi-Fi Protected Setup (WPS) Wi-Fi Protected Setup (WPS) is the simplest way to build connection between wireless network clients and this wireless router. You don‟t have to select encryption mode and input a long encryption passphrase every time when you need to setup a wireless client, you only have to press a button on wireless client and this wireless router, and the WPS will do the rest for you. This wireless router supports two types of WPS: Push-Button Configuration (PBC), and PIN code.
Here are descriptions of every setup items: Enable WPS (1): Check this box to enable WPS function, uncheck it to disable WPS. WPS Information (2):WPS-related system information will be displayed here: WPS Status: If the wireless security (encryption) function of this wireless router is properly set, you‟ll see „Configured‟ message here. If wireless security function has not been set, you‟ll see „unConfigured‟. PinCode Self: This is the WPS PIN code of this wireless router.
Configure Click „Start PBC‟ to start Push-Button style WPS by Push Button (4): setup procedure. This wireless router will wait for WPS requests from wireless clients for 2 minutes. The „WLAN‟ LED on the wireless router will be steady on for 2 minutes when this wireless router is waiting for incoming WPS request. Configure by client PinCode (5): Please input the PIN code of the wireless client you wish to connect, and click „Start PIN‟ button.
2-7-6 Security Tips for Wireless Network Here are some quick tips to help you improve the security level of your wireless network: 1. Never use simple words (like school, apple and computer) as WEP encryption or WPA passphrase. 2. A complicated (the combination of number, alphabet, even symbol, and long enough) WEP key and WPA passphrase is much safer than simple and short ones.
Chapter III Advanced Functions 3-1 Quality of Service (QoS) Quality of service provides an efficient way for computers on the network to share the internet bandwidth with a promised quality of internet service.
Here are descriptions of every setting: Enable QoS (1): Check this box to enable QoS function, unselect this box if you don‟t want to enforce QoS bandwidth limitations.

4-3 Glossary Default Gateway (Router): Every non-router IP device needs to configure a default gateway‟s IP address. When the device sends out an IP packet, if the destination is not on the same network, the device has to send the packet to its default gateway, which will then send it out towards the destination. DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives every computer on your home network an IP address.
A network mask is also a 32-bit binary pattern, and consists of consecutive leading 1‟s followed by consecutive trailing 0‟s, such as 11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be described simply as “x” number of leading 1‟s. When both are represented side by side in their binary forms, all bits in the IP address that correspond to 1‟s in the network mask become part of the IP network address, and the remaining bits correspond to the host ID.

They both run on top of the IP (Internet Protocol), a network layer protocol. WAN: Wide Area Network.
