G-1000 User’s Guide

28 Chapter 1 Getting to Know Your G-1000

1.2.2.4 802.11g Wireless LAN Standard

The G-1000 complies with the 802.11g wireless standard and is also fully compatible with the

802.11b standard. This means an 802.11b radio card can interface directly with an 802.11g

device (and vice versa) at 11 Mbps or lower depending on range. 802.11g has several

intermediate rate steps between the maximum and minimum data rates. The 802.11g data rate

and modulation are as follows:.

1.2.2.5 STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches,

bridges or routers. It allows a bridge to interact with other (R)STP -compliant bridges in your

network to ensure that only one path exists between any two stations on the network.

1.2.2.6 Limit the number of Client Connections

You may set a maximum number of wireless stations that may connect to the G-1000. This

may be necessary if for example, there is interference or difficulty with channel assignment

due to a high density of APs within a coverage area.

1.2.2.7 Brute-Force Password Guessing Protection

The G-1000 has a special protection mechanism to discourage brute-force password guessing

attacks on the G-1000's management interfaces. You can specify a wait-time that must expire

before entering a fourth password after three incorrect passwords have been entered. Please

see the appendix for details about this feature.

1.2.2.8 Wireless LAN MAC Address Filtering

Your G-1000 checks the MAC address of the wireless station against a list of allowed or

denied MAC addresses.

1.2.2.9 WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless

network to help keep network communications private.

Note: The G-1000 may be prone to RF (Radio Frequency)

interference from other 2.4 GHz devices such as microwave

ovens, wireless phones, Bluetooth enabled devices, and other

wireless LANs.
