iii W arning This section explains the symbols, signs and ter minology used in this manual. The following terminology is used in this manual to distinguish between an Ethernet 10/100B ASE-T LAN and a Wireless LAN and should not be constr ued as gener ally accepted terminology outside this context.
1 PA R T I 1.0 Introduction I The WLM2-G54 protects customer s’ investments o ver the long term. Buffalo’s new WLAN product, WLM2-G54, is the IEEE802.11g-based access point (AP). The Buffalo solution offers simultaneous commu- nication on both 11Mbps and 54Mbps bands without annoying bottlenecks.
2 5.0 F eatures The Buffalo AirStation Intelligent access point provides the f eatures necessar y in today ’ s business environment, with a high level of reliability and security . Use of these features along with VPN will allo w the user to hav e the highest security a WLAN can offer .
3 TKIP – T empor al Key Integr ity Protocol is an advanced encr yption method using the RC4 algorithm. Instead of using the sequential IV , a random IV will be used, and the IV key definition will be updated regularly at a preset time inter val.
4 5.2.3 Spanning T ree (IEEE802.1d) Network looping often results in repeated packet transmission, which causes overloads and interr uption of communications. The Spanning T ree in a network loop disconnects one of the links, rerouting the tr affic in the event of failure, avoiding pack et sending repetition and increasing network stability .
5 the Syslog ser ver as a par t of its administra- tive utilities, it is possible to use additional off- the-shelf Syslog ser ver software. 5.5 Easy Support Features Buffalo periodically releases new firmware updates for AirStation products.
