Refer to the ISP (Internet Service Provider) and select the appropriate option and fill in the information needed to connect. Here you may change the setting for IP address, PPPoE, DNS, etc… DHCP: If the user set the device as DHCP client, the device will get automatically IP address from the DHCP server. Fixed IP: The user can specify an IP address.
PPPoE: Enter the username and password you use when logging onto your ISP through a PPPoE connection. MAC address: It shows the MAC address of the WAN interface. Clone MAC Address: Clone MAC address allows the user to copy the previous MAC address and using it on your new network. 3.2 LAN interface setup The user can configure the parameters for local area network which connects to the LAN port of your Access Point. Here you may change the setting for IP address, subnet mask, DHCP,etc.. MAC address: It shows the MAC address of the LAN interface. IP address: The IP address of the LAN interface. The default IP address is 192.168.1.1. Subnet Mask: The subnet mask of the LAN interface. The default subnet mask is 255.255.255.0.
3.3 Wireless interface setup The user can configure the parameters for wireless network which connects to the wireless LAN port of your Access Point. Here you may change the settings for alias name, SSID, channel number, etc... MAC address: It shows the MAC address of the WLAN interface. Disable Wireless: The user can disable the wireless function. Channel: Select the appropriate channel from the list provided to correspond with your network settings. All devices in your wireless network must use the same channel in order to function correctly. SSID: The SSID is the network name shared among all devices in a wireless network. The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character. Make sure this setting is the same for all devices in your wireless network. Broadcast SSID: A zero byte length SSID is called the broadcast SSID, an access point can respond to computers sending probe packets with the broadcast SSID. If this feature is enabled on the access point, any wireless user can associate with the access point by using a blank (null) SSID. Associated Clients: Click "Show Active Clients", the table shows the MAC address, transmission, reception packet counters and encrypted status for each associated wireless client. Mode: Enable encryption allows you to setup WEP key value. Key Length: There are 2 levels of encryption to use, the user can select 64-bit or 128-bit.
Key Format: ASCII or HEX. ASCII. (American Standard Code for Information Interchange): Consists of 256 numbers assigned to the alphabet, numbers, punctuation, control character and etc. hexadecimal notation: While the more common decimal system uses a base of ten to represent all possible numbers, hexadecimal notation uses a base of sixteen: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, A, B, C, D, E, F. While such a system may seem confusing at first, it works extremely well in computing environments. For example, a single byte of information can be represented as eight bits (10011101), decimal numerals (913), or simplified to hex (9D). In hex, every byte can be shown as two hexadecimal characters. Default Tx Key: Select the key number to use. Encryption Key Number: Each key must consist of ASCII or HEX digits.

6 Advanced Wireless This page is used to configure the parameters for wireless LAN clients which may connect to your Access Point and these settings are only for more technically advanced users who have a sufficient knowledge about wireless LAN. Here you may change wireless encryption settings as well as wireless network parameters. If you enable wireless access control, only those clients whose wireless MAC addresses are in the access control list will be able to connect to your Access Point. When this option is enabled, no wireless clients will be able to connect if the list contains no entries.
6.1 Advanced setup These settings are only for more technically advanced users who have a sufficient knowledge about wireless LAN. These settings should not be changed unless you know what effect the changes will have on your device. Authentication Type: Open system or share key. Open system: The default authentication service that simply announces the desire to associate with another station or access point. A station can authenticate with any other station or access point using open system authentication if the receiving station designates open system authentication. Share key: The optional authentication that involves a more rigorous exchange of frames, ensuring that the requesting station is authentic. For a station to use shared key authentication, it must implement WEP. Fragment Threshold: Fragment threshold defines a threshold above, which the wireless packet will be split up, or fragmented. For a fragmented packet, if transmission of part of it were to be interfered with, only the portion that was successfully transmitted would need to be resent. Throughput will generally be lower for fragmented packets, since the fixed packet overhead consumes a higher portion of the RF bandwidth. RTS Threshold: The RTS threshold sets an upper threshold at which point the device will issue an RTS packet. The RTS (Request to Send) packet is used for the purpose of avoiding data collisions on the wireless LAN. There are several trade offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference or collisions. Refer to the IEEE 802.11 standard for more information on the RTS/CTS mechanism. Beacon Interval: This represents the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). Data Rate: The actual rate at which data transmission occurs varies according to the strength of signal transmitting the data. Distance and environment can affect the strength of the signal that can be transmitted and received. The signal strength determines the type of modulation technique used to encode data, which affects the volume of data (i.e. the number of bits) that can be encoded in a given space of the carrier signal. The IEEE 802.11b standard specifies that WLAN devices adapt the rate
of transmission to use the best rate achievable. Each wireless device first determines if conditions diminish signal strength and then chooses one of four possible bit rates (1, 2, 5.5, or 11 Mbps) based on this learned information. By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options: Auto, 1, 2, 5.5, or 11 Mbps. For most networks the default setting, Auto will be the best choice. When (Auto Rate Fall Back) is enabled the transmission rate will select the optimum rate. If obstacles or interference are present, the system will automatically fall back to a lower rate. Preamble Type: Preamble is the first sub-field of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance. The Preamble type of Node should be the same as AP’s when in Access Point Client mode. 6.2 Access control If the user enables wireless access control, only those clients whose wireless MAC addresses are in the access control list will be able to connect to your device. When this option is enabled, no wireless clients will be able to connect if the list contains no entries. To save all the settings, click “Apply Changes”. After the device save all the settings, it will show as following, then click “OK” to finish the saving. Only those MAC addresses which match to the control list can associate with the router. If the user wants to deny one of the MAC address listed in the list, check “Selected” and click “Delete Selected” or click “Delete All” to deny all clients.
