NETGEAR WG111U user manual European Regulatory Requirements for Transmit Power Control

User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U

•RTS/CTS Threshold: RTS is request to send and CTS is clear to send; their purpose is to avoid collisions. RTS/CTS will be enabled if the data frame size is larger than the threshold value set here. The maximum frame size is 2346 octets, so if the threshold is 2346, RTS/CTS will be disabled.

Note: This setting is reserved for wireless testing and advanced configuration only. Do not change this setting unless you are sure you need to. The primary reason for implementing RTS/CTS is to minimize collisions between hidden stations. This occurs when users and access points are spread out and a high number of retransmissions occur on the wireless LAN.

European Regulatory Requirements for Transmit Power Control

Follow the instructions below only if you are operating in Europe and want to use the Advanced 802.11a 5 GHz settings of the WG111U.

Note: If you are not operating in Europe or do not want to use the Advanced 802.11 a settings, continue on to Chapter 5, “Wireless Security Configuration”.

TPC Configuration Procedure

The end user is obligated to follow the procedure below in order to operate this device in accordance with European regulatory requirements for Transmit Power control. The TPC feature implemented in this Wireless LAN device must be configured by the end user when operating in any European Community country.

The Wireless LAN Adapter includes a transmit power adjustment found in the Advanced Settings section under the Settings page of the Client Utility. The Transmit Power Level pull-down list includes the following settings: 100%, 50%, 25%, 12.5%, Lowest. The default setting is 100%, which represents no reduction in power. The following procedure verifies whether a reduction to

50% or 25% should be set:

1.Check the current link rate:

a.When connected to your Wireless Infrastructure (home, corporate or public Wireless network), use the NETGEAR WG111U Smart Wizard Wireless Assistant to check that a connection is established.

b.Check current transmit & receive link rates by viewing the status line at the bottom of the Smart Wizard Wireless Assistant screen. The highest possible link rate is 54Mbps. Note the current value.

2.Check whether the maximum link rate is currently achieved. If the current link rate found in step 1 is...
