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.

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.

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.
