i n t e l l i g e n t w i r e l e s s p l a t f o r m 2.8.8. Security The different types of Security that can be configured on a Remote Router/NAT are as follows: 1. WEP Only 2. WPA –RADIUS 3. WPA –PSK 4. WPA2-RADIUS 5. WPA2-PSK Note: Default Security is None. WEP: Wireless Equivalent Privacy (WEP) encryption is used for security between the aCNPT and the airPoint or any other access point.
i n t e l l i g e n t w i r e l e s s p l a t f o r m 4. Choose a WEP Key Size (64 Bits or 128 Bits) from the pull-down list.

Click the ’Apply Changes’ button to change the settings. Note: The system will validate the key entries and provide error or warning notifications.
i n t e l l i g e n t w i r e l e s s p l a t f o r m Figure: 2-27 Configuring WPA-PSK Table 2-6 WPA Descriptions Page Items WPA-PSK WPA-Shared Key Descriptions WPA-PSK is an extra-strong encryption where encryption keys are automatically changed (called rekeying) and authenticated between devices after a specified period of time, or after a specified number of packets has been transmitted. WPA-PSK is far superior to WEP and provides stronger protection for the home/SOHO user for two reasons.

Click the ‘Security’ link from the ‘Radio Main’ page. 2. Select the WPA2-RADIUS from the drop down menu of the Security Mode. 3.
i n t e l l i g e n t w i r e l e s s p l a t f o r m 3. Performance Parameters and Bandwidth Controller This chapter gives instructions for editing the wireless radio protocol parameters to optimize radio performance and changing the Bandwidth Controller. These procedures are the same for all the three modes. 3.1.
i n t e l l i g e n t Throughput Optimizer w i r e l e s s p l a t f o r m The Throughput Optimizer is used to optimize the radio Link speed and performance. The Valid range is 0 to 10. The default value is 6. Setting a higher value will cause the radio to attempt to establish at the highest possible data rate in an aggressive way. A smaller "Throughput Optimizer" value means a more stable link. Frame Bursting Piggy Back Note: The default value for the Throughput Optimizer is 6.
i n t e l l i g e n t w i r e l e s s p l a t f o r m 3.2. Bandwidth Controller Using the Bandwidth Controller on the aCNPT, the user can limit the wireless link bandwidth for the upload/download speed. The default is disabled and provides bandwidth up to 6Mbps. This is subject to the available upstream bandwidth, signal level and distance. The user can key in the upload and download bandwidth for the wireless link. Follow the steps below to change the bandwidth parameters: 1.

i n t e l l i g e n t w i r e l e s s p l a t f o r m 4. Quality of Service (QoS) The primary goal of QoS is to provide priority for certain applications by dedicating bandwidth, controlling jitter and latency (which are required by some real-time and interactive traffic), and improving loss characteristics. However, it is important to ensure that providing priority for one or more flows would not cause the other flows to fail. QoS in 802.11 is defined by the IEEE 802.11e set of standards.
i n t e l l i g e n t w i r e l e s s p l a t f o r m Figure 4-2: QoS front page In total, there are 9 different classes which can be configured. Note: Class 1 indicates the default value. In order to define the filters for a class, follow the steps below: 1. Click on “Filters”. 2. Select the application packet that has to be filtered. Figure 4-3: Selection Menu of Application Filter.
i n t e l l i g e n t w i r e l e s s p l a t f o r m 3. Select whether the packet has to be filtered based on the IP or MAC. Figure 4-4: Selection Menu of IP/MAC based filter 4. Select whether the packet has to be filtered based on source address or the destination address. If the packet being filtered is based on IP, then enter the IP address. If it is based on MAC, then enter the MAC address.

Every IP packet sent over the network includes a TOS field in the header that indicates how the data should be prioritized and transmitted over the network. The access point examines the TOS field in the headers of all packets that pass through the AP.

i n t e l l i g e n t w i r e l e s s p l a t f o r m WEP According to the IEEE 802.11 standard, Wired Equivalent Privacy (WEP) is intended to provide “confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium and that does not employ cryptographic techniques to enhance privacy.” WEP relies on a secret key that is shared between a mobile station and an access point. WEP uses the RC4 stream cipher invented by RSA Data Security.
i n t e l l i g e n t w i r e l e s s p l a t f o r m DHCP DHCP stands for ‘Dynamic Host Configuration Protocol’ and is a means for networked computers to get their TCP/IP networking settings from a central server. Importantly, DHCP assigns IP addresses and other TCP/IP configuration parameters automatically. SNMP Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The first versions of SNMP were developed in the early 80s.
