ZyXEL G-1000 v2 User’s Guide

ZyAIR LED

The blue ZyAIR LED (also known as the breathing light) is on when the G-1000 v2 is on and blinks (or breaths) when data is being transmitted to/from its wireless stations. You may use the web configurator to turn this light off even when the G-1000 v2 is on and data is being transmitted/received.

WPA and WPA2

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.

Key differences between WPA(2) and WEP are improved data encryption and user authentication.

IEEE 802.11b Wireless LAN Standard

The G-1000 v2 complies with the IEEE 802.11b wireless standards.

The IEEE 802.11b data rate and corresponding modulation techniques are shown in the table below. The modulation technique defines how bits are encoded onto radio waves.

IEEE 802.11g Wireless LAN Standard

The G-1000 v2, complies with the IEEE 802.11g wireless standard and is also fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b radio card can interface directly with an IEEE 802.11g device (and vice versa) at 11 Mbps or lower depending on range.The IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:.
