Access Point - Access Point mode allows wireless stations including AP clients to access. Enable SSID Broadcast - If you select the Enable SSID Broadcast checkbox, the Wireless Access Point SSID will broadcast its name (SSID) on the air.
Client - This mode allows one or more remote LANs connect with a central LAN, and thus creating an extended virtual LAN. In this way, any station of the Remote LAN can successfully communicate with any station of the central LAN, as if all of them belong to the same physical LAN. Wireless Stations cant associate with AP Clients.
Enable WDS - The AP client can connect to AP with WDS enabled or disabled. If WDS is enabled, all traffic from wired networks will be forwarded in the format of WDS frames consist of four address fields. If WDS is disabled, three address frames are used. If your AP supports WDS well, please select the option. SSID - Enter the SSID of AP that you want to access. If you select the radio before SSID, the AP client will connect to AP according SSID. MAC of AP - Enter the MAC address of AP that you want to access. If you select the radio before MAC of AP, the AP client will connect to AP according MAC address.
Repeater - A wireless repeater is an AP with its own BSS that relays data to a root AP, to which it is associated. The wireless repeater relays signal between its stations and the root AP for greater wireless range. Please input the MAC address of root AP in the field of MAC of AP. Universal Repeater - APs without WDS function can also be communicated with in this mode Note: If the available AP cant support with WDS, you may select Client mode without WDS or Universal Repeater mode to associate with the AP. Here is an example of how to configure wireless repeater. Please do the following: 1. Configure the Operating Mode of the TL-WA501G Access Points.

Appendix A:

Glossary
2x to 3x eXtended RangeTM WLAN Transmission Technology - The WLAN device with 2x to 3x eXtended RangeTM WLAN transmission technology make its sensitivity up to 105 dBm, which gives users the ability to have robust, longer-range wireless connections. With this range-enhancing technology, a 2x to 3x eXtended RangeTM based client and access point can maintain a connection at as much as three times the transmission distance of traditional 802.11b and 802.11g products, for a coverage area that is up to nine times greater. A traditional 802.11b and 802.11g product transmission distance is about 300m. A 2x to 3x eXtended RangeTM based client and access point can maintain a connection transmission distance may be up to 830m. 802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks. 802.11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP encryption for security. Access Point (AP) - A wireless LAN transceiver or "base station" that can connect a wired LAN to one or many wireless devices. Access points can also bridge to each other. DNS (Domain Name System) An Internet Service that translates the names of websites into IP addresses. Domain Name - A descriptive name for an address or group of addresses on the Internet. DoS (Denial of Service) - A hacker attack designed to prevent your computer or network from operating or communicating. DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over existing traditional phone lines. ISP (Internet Service Provider) - A company that provides access to the Internet. MTU (Maximum Transmission Unit) - The size in bytes of the largest packet that can be transmitted. SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11 standard. Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group promoting interoperability among 802.11b devices. WLAN (Wireless Local Area Network) - A group of computers and associated devices communicate with each other wirelessly, which network serving users are limited in a local area.

WPA (Wi-Fi Protected Access) - WPA is a security technology for wireless networks that improves on the authentication and encryption features of WEP (Wired Equivalent Privacy). In fact, WPA was developed by the networking industry in response to the shortcomings of WEP. One of the key technologies behind WPA is the Temporal Key Integrity Protocol (TKIP). TKIP addresses the encryption weaknesses of WEP. Another key component of WPA is built-in authentication that WEP does not offer. With this feature, WPA provides roughly comparable security to VPN tunneling with WEP, with the benefit of easier administration and use. This is similar to 802.1x support and requires a RADIUS server in order to implement. The Wi-Fi Alliance will call this, WPA-Enterprise. One variation of WPA is called WPA Pre Shared Key or WPA-PSK for short - this provides an authentication alternative to an expensive RADIUS server. WPA-PSK is a simplified but still powerful form of WPA most suitable for home Wi-Fi networking. To use WPA-PSK, a person sets a static key or "passphrase" as with WEP. But, using TKIP, WPA-PSK automatically changes the keys at a preset time interval, making it much more difficult for hackers to find and exploit them. The Wi-Fi Alliance will call this, WPA-Personal.

I cannot access the AP with a wireless capable computer.
There is a configuration problem. Check these items:
1) 2) You may not have restarted the computer with the wireless adapter to have TCP/IP changes take effect. Restart the computer. The computer with the wireless adapter may not have the correct TCP/IP settings to communicate with the network. Restart the computer and check that TCP/IP is set up properly for that network. The usual setting for Windows the Network Properties is set to Obtain an IP address automatically. The access points default values may not work with your network. Check the access point default configuration against the configuration of other devices in your network.
