    Always double check for any missing parts from the kit you received before deployment. The next step is to set up the computer Ethernet interface for configuring the TT900. Since the default IP Address of the unit is on the 192.168.10.x IP range in both Client Bridge and AP mode you will need to set the Ethernet interface within the same IP range, where x will have to be a free IP address number from 1-254.

  • Page 19 WPA Configuration Short for Wi-Fi Protected Access, WPA is a Wi-Fi standard that was designed to improve upon the security features of WEP. WPA has the following improvements over WEP: • Improved data encryption through temporal key integrity protocol (TKIP). TKIP scrambles the keys using a hashing algorithm.
  • Page 20 Cipher Type • TKIP Temporal Key Integrity Protocol is an upgrade to the WEP known as WEP 1.1 that fixes known security problems in WEP’s implementation of the RC4 stream cipher. TKIP scrambles the keys using a hashing algorithm and by adding an integrity-checking feature, ensures that the keys haven’t been tampered with.
  • Page 21 the MAC address does not provide sufficient security because the MAC address of a wireless client can be spoofed. • Shared Key - Shared key authentication supports authentication of stations as either a member of those who know a shared secret key or a member of those who do not. Shared key authentication is not secure and is not recommended for use.
  • Page 22 Admin Device Name This is the name that the bridge will use to identify itself to external configuration and IP address programs. This is not the same as the SSID. It is okay to leave this blank if you are not using these programs. SNMP Setting SNMP enable Option to enable or disable SNMP support.
  • Page 23 Factory default setting for the read-only community string is set to "public". It is standard practice to change all the community strings so that outsiders cannot see information about the internal network. (In addition, the administrator may also employ firewalls to block any SNMP traffic to ports 161 and 162 on the internal network.) Change this value to have InterMapper use the new string when querying SNMP devices.
  • Page 24 Security This section is used to set up the administrative login name and password. User name This is the user name that you must type when logging into the web interface. Administrator Password This is the password that you must type when logging into the web interface. You must enter the same password into both boxes for confirmation.
  • Page 25 The TT900 has implemented a hardware modification authorization process to prevent use by fraudulent hardware from other manufacturers. This will require any hardware change on the radio card used on the TT900 to input a serial code generated based on each unique MAC address. Please contact Teletronics Support to a pickup a valid serial number to deactivate the pre-registration protection after a radio card swap.

  • Page 27 Cloning Cloning Mode • WLAN Card If set to "WLAN Card", the MAC Address of the WLAN Card will be used. When multiple Ethernet devices are connected to the Bridge, the MAC Address of the Bridge will not change. • Ethernet Client If set to "Ethernet Client", the MAC Address from the first Ethernet client that transmits data through the Bridge will be used.

The 802.11d specification is well suited for systems that want to provide global Roaming. ACK Timeout When a packet is sent out from 802.11 Station A it will wait for an 'ACKnowledgement frame' from 802.11 Station B.

  • Page 38 Remote RADIUS server configuration settings. There are two sections to setup 2 RADIUS servers for the TT900 to connect to. At any given time the TT900 will connect to one RADIUS server for authentication and will use the other one as a backup if that option is configured.

MAC Address Authentication Use client MAC address for authentication with RAIDUS server. WEP Configuration Short for Wired Equivalent Privacy, a security protocol for wireless local area networks (WLANs) defined in the 802.11b standard.
  • Page 40 Shared key authentication uses the following process: 6. The authentication-initiating wireless client sends a frame consisting of an identity assertion and a request for authentication. 7. The authenticating wireless node responds to the authentication-initiating wireless node with challenge text. 8. The authentication-initiating wireless node replies to the authenticating wireless node with the challenge text that is encrypted using WEP and an encryption key that is derived from the shared key authentication secret.

  • Page 46 Advanced Advanced Wireless Fragmentation threshold Fragmentation Threshold is the maximum length of the frame beyond which payload must be broken up (fragmented) into two or more frames. Collisions occur more often for long frames because sending them occupies the channel for a longer period of time, increasing the chance that another station will transmit and cause collision.
  • Page 47 Burst time Maximum burst time is a feature based on the PRISM Nitro; a new WLAN software solution that more than triples 802.11g throughput in a mixed-mode environment and offers up to 50 percent greater throughput performance in 802.11g-only networks. PRISM Nitro is fully IEEE 802.11 compliant and uses prioritization algorithms and enhanced protection mechanisms to significantly increase wireless networking performance.The recommended value for the maximum burst time for 11b or the mixed 11b/g environment is 650.
  • Page 48 When a packet is sent out from 802.11 Station A it will then wait for an 'ACKnowledgement frame' from 802.11 Station B. Station A will only wait for a certain amount of time (ACK timeout) or ACK window. If the ACK is NOT received within that timeout period then the packet will be re-transmitted from Station A resulting in reduced throughput.

  • Page 56: Appendix F: Tt900 Upgrade Faq

    Teletronics has now removed the necessary step to provide an activation key to change from SU to AP and vice versa in our TT900 product line. For example, if you have a TT900 in SU mode with 3.6.0 firmware, the activation key is not required if you upgrade to either 3.7.0 (SU mode) or 3.7.1 (AP mode), or later.
  • Page 57 Will upgrade keep my previous configuration? Although the upgrade might keep your previous configuration, we suggest customer to reset the unit to factory default located in “admin” section and configure it again.
