Wireless-G Access Point with SRX

The Wireless - Advanced Wireless Settings Tab

This screen allows you to configure the advanced settings for the Access Point. In most cases, these settings do not need to be changed.

Advanced Wireless

You can change the data transmission and output power settings for the Access Point.

Authentication Type. Select the authentication method you want the Access Point to use, Shared Key, Open System, or Auto. Shared Key is when both the sender and the recipient share a WEP key for authentication. Open System is when the sender and the recipient do not share a WEP key for authentication. All devices on your network must use the same authentication type. In most cases, keep the default, Open System, otherwise use Auto.

CTS Protection Mode. The CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to catch all Wireless-G transmissions but will severely decrease performance. Select Enable if you want to permanently enable this feature, or keep the default, Disable, if you want to permanently disable this feature. In most cases, CTS Protection Mode should remain disabled, unless the Wireless-G products are experiencing severe problems trying to transmit to the Access Point in an environment with heavy 802.11b traffic.

ACK Mode. This setting prioritizes QoS for users who also have ACK Mode enabled. Users with Immediate ACK (the default setting) will experience reliable connectivity for normal network use. Burst ACK is faster but less reliable and may also affect long-range wireless performance. The No ACK setting disables the ACK feature. Clients utilizing ACK must have their wireless adapter on the same setting as the Router. This is normally used in a multicast broadcast like video. Do not use this unless you are an advanced user.

Transmission Rates. The range is from 1 to 108Mbps. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can keep the default setting, Auto (Default), to have the Access Point automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Access Point and a wireless client.

Preamble Type. The preamble defines the length of the CRC block for communication between the Access Point and the roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate preamble type, Long Preamble (default) or Short Preamble.

Network Density. This setting is a reflection of the Access Point’s range. Setting the density to Low provides you with a greater range. Setting the density to High gives you a lower range. The default setting is Low.
