In Infrastructure BSS networks, the BSSID is the MAC (Medium Access Control) address of the AP (Access Point) and in Independent BSS or ad hoc networks, the BSSID is generated randomly. 7.1.1 Security Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.
Option Description Select SSID Sets the wireless network name. Identifier. SSID stands for Service Set All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. The naming conventions are: Minimum is one character and maximum number of characters: 32 bytes.
Network It specifies the network authentication. When this checkbox is Authentication selected, it specifies that a network key be used for authentication to the wireless network. If the Network Authentication (Shared mode) checkbox is not shared (that is, if open system authentication is used), no authentication is provided. Open system authentication only performs identity verifications. Different authentication type pops up different settings requests. Choosing 802.
Choosing WPA-PSK, you must enter WPA Pre-Shared Key and Group Rekey Interval. WEP It specifies that a network key is used to encrypt the data is sent over Encryption the network. When this checkbox is selected, it enables data encryption and prompts the Encryption Strength drop-down menu. Data Encryption (WEP Enabled) and Network Authentication use the same key. Encryption A session’s key strength is proportional to the number of binary bits strength comprising the session key file.
7.1.2 MAC Filter This MAC Filter page allows access to be restricted/allowed based on a MAC address. All NICs have a unique 48-bit MAC address burned into the ROM chip on the card. When MAC address filtering is enabled, you are restricting the NICs that are allowed to connect to your access point. Therefore, an access point will grant access to any computer that is using a NIC whose MAC address is on its “allows” list.
Option Description MAC Restrict Mode Radio buttons that allow settings of; Disabled: MAC filtering function is disabled. Allow: Permits PCs with listed MAC addresses to connect to the access point. Deny: Prevents PCs with listed MAC from connecting to the access point. MAC Address Lists the MAC addresses subject to the Off, Allow, or Deny instruction.
7.1.3 Wireless Bridge This page allows you to configure wireless bridge features of the wireless LAN interface. You can select Wireless Bridge (also known as Wireless Distribution System) to disable access point functionality. Selecting Access Point enables access point functionality. Wireless bridge functionality will still be available and wireless stations will be able to associate to the AP. Select Disabled in Bridge Restrict, which disables wireless bridge restriction.
7.1.4 Advanced The Advanced page allows you to configure advanced features of the wireless LAN interface. You can select a particular channel on which to operate, force the transmission rate to a particular speed, set the fragmentation threshold, set the RTS threshold, set the wakeup interval for clients in power-save mode, set the beacon interval for the access point, set XPress mode and set whether short or long preambles are used. Click Apply to configure the advanced wireless options.
The new amendment allows IEEE 802.11g units to fall back to speeds of 11 Mbps, so IEEE 802.11b and IEEE Band 802.11g devices can coexist in the same network. The two standards apply to the 2.4 GHz frequency band. IEEE 802.11g creates data-rate parity at 2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps rate at 5 GHz. (IEEE 802.11a has other differences compared to IEEE 802.11b or g, such as offering more channels.) Channel Drop-down menu that allows selection of a specific channel.
DTIM Interval Delivery Traffic Indication Message (DTIM), also known as Beacon Rate. The entry range is a value between 1 and 65535. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast and multicast messages. Beacon Interval The default is 1.
Preamble Type Short preamble is intended for application where maximum throughput is desired but it doesn’t cooperate with the legacy. Long preamble interoperates with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 802.11-1999 Transmit Power The Router will set different power output (by percentage) according to this selection.

Appendix B: Firewall Stateful Packet Inspection Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header. Denial of Service attack Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have.
Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be dropped. Destination Port: This can take on either a single port number or a range of port numbers. Packets having a destination port equal to this value or falling within the range of port numbers(portX : portY) will be dropped. Examples: 1. Filter Name : Out_Filter1 Protocol : TCP Source Address : 192.168.1.45 Source Subnet Mask : 255.255.255.
Filter Name: User defined Filter Name. Protocol: Can take on any values from: TCP/UDP, TCP, UDP or ICMP Source IP Address/Source Subnet Mask: Packets with the particular "Source IP Address/Source Subnet Mask" combination will be accepted. Source Port: This can take on either a single port number or a range of port numbers. Packets having a source port equal to this value or falling within the range of port numbers(portX : portY) will be accepted.
