System events are recorded in the memory of the IEEE 802.11b/g. The logged information is useful
for troubleshooting purposes. The system events are divided into several categories, and you can se-
lect which categories of events to log. See Section 3.6.2.2 for more information.
3.2.4. Link Monitor
Fig. 17: Link monitor
When the IEEE 802.11b/g is in AP Client mode, you can use the Link Monitor status page to monitor
the link quality and signal strength sensed by its RF module. Larger values means better wireless
connectivity to its associated Access Point. This feature is especially useful when you are aligning a
pair of directional antennas for bridging applications.
NOTE: The values are updated every 20 seconds.
3.3. General Operations
3.3.1. Specifying Operational Mode
Fig. 18: Operational modes settings
The IEEE 802.11b/g supports two operational modes:
 AP/Bridge. This mode provides both Access Point and Static LAN-to-LAN Bridging
functionality. The static LAN-to-LAN bridging function is supported through Wireless
Distribution System (WDS).
 AP Client. This mode is for Dynamic LAN-to-LAN Bridging. The AP Client automati-
cally establishes bridge links with APs from any vendors.
In either mode, the IEEE 802.11b/g forwards packets between its Ethernet interface and wireless in-
terface for wired hosts on the Ethernet side and wireless host(s) on the wireless side.
There are 2 types of wireless links as specified by the IEEE 802.11 standard.
 STA-AP. This type of wireless link is established between an IEEE 802.11 Station (STA)
and an IEEE 802.11 Access Point (AP). An STA is usually a client computer (PC or PDA)
with a WLAN network interface card (NIC). The AP Client mode is actually an STA.
