How to position a Wireless Router / Access Point
- Install the wireless router or access point in a central location, for example, in the center location of the building.
- Avoid physical obstructions, such as Plaster or brick walls, Cabinets, furniture.
- Avoid reflective surfaces, such as Mirrors, Metal file cabinets, Stainless steel countertops.
- Install the wireless access point or router at least 1 m (3feet) away from other home appliances that send wireless signals in the same frequency range, such as microwave ovens, cordless telephones, baby monitors. Install the unit away from electrical equipment, such as electric fans, motors, fluorescent lighting.

What and how to find my PC's IP and MAC address?
P address is the identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, could be an IP address.
The MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet from your computer (or host as the Internet protocol thinks of it), a correspondence table relates your IP address to your computer's physical (MAC) address on the LAN.
To find your PC's IP and MAC address
* Open the Command program in the Microsoft Windows.
* Type in "ipconfig /all", then press the Enter button.
* Your PC's IP address is the one entitled IP Address and your PC's MAC address is the one entitled Physical Address.

What is Wireless LAN?
A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wired connections to the user's machine.

What is BSSID?
A six-byte address is that distinguish a particular a particular access point from others. Also know as just SSID. Serve as a network ID or name.

What is ESSID?
The Extended Service Set ID (ESSID) is the name of the network you want to access. It is used to identify different wireless networks.

What is WEP?
An option of IEEE 802.11 function is that offers frame transmission privacy similar to a wired network. The Wired Equivalent Privacy generates secret shared encryption keys that both source and destination stations can use to alert frame bits to avoid disclosure to eavesdroppers.
WEP relies on a secret key that is shared between a mobile station (e.g. a laptop with a wireless Ethernet card) and an access point (i.e. a base station). The secret key is used to encrypt packets before they are transmitted, and an integrity check is used to ensure that packets are not modified in transit.

What is WPA2?
It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11 standard.

What is Wi-Fi Protected Access (WPA)?
Wi-Fi's original security mechanism, Wired Equivalent Privacy (WEP), has been viewed as insufficient for securing confidential business communications. A longer-term solution, the IEEE 802.11i standard, is under development. However, since the IEEE 802.11i standard is not expected to be published until the end of 2003, several members of the WI-Fi Alliance teamed up with members of the IEEE 802.11i task group to develop a significant near-term enhancement to Wi-Fi security. Together, this team developed Wi-Fi Protected Access.
To upgrade a WLAN network to support WPA, Access Points will require a WPA software upgrade. Clients will require a software upgrade for the network interface card, and possibly a software update for the operating system. For enterprise networks, an authentication server, typically one that supports RADIUS and the selected EAP authentication protocol, will be added to the network.

There are three ways to make the WPS connection
WPS is short for Wi-Fi Protected Setup, it is an easy method for setting up a wireless secured connection between wireless router (or AP) and client (adapter) quickly.
- Press the WPS button on both wireless router and client;
- Register client's PIN code on router's WEB manage page;
- Register router's PIN code on client's utility.

What is SSID Broadcast?
Broadcast of SSID is done in access points by the beacon. This announces your access point (including various bits of information about it) to the wireless world around it. By disabling that feature, the SSID configured in the client must match the SSID of the access point.
Some wireless devices don't work properly if SSID isn't broadcast (for example the D-link DWL-120 USB 802.11b adapter). Generally if your client hardware supports operation with SSID disabled, it's not a bad idea to run that way to enhance network security. However it's no replacement for WEP, MAC filtering or other protections.
