The Wireless Tab - Advanced Wireless Settings
This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by
an expert administrator as incorrect settings can reduce wireless performance.
Advanced Wireless Settings
Preamble Type. The preamble defines the length of the CRC block for communication between the Router and
the roaming wireless adapters. (High network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type for your network. If you are not sure which setting to select, then keep the default
setting, Long Preamble.
Authentication Type. The default is set to Auto, which allows Open System and Shared Key authentication. For
Open System authentication, the sender and the recipient do not use a WEP key for authentication but can use
WEP for data encryption. For Shared Key authentication, the sender and recipient use a WEP key for both
authentication and data encryption. To only allow Open System authentication, select Open. To only allow
Shared Key authentication, select Shared Key. In most cases, you should keep the default setting, Auto,
because some clients cannot be configured for Shared Key.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the Router’s ability to catch all
Wireless-G transmissions but will severely decrease performance. Keep the default setting, Auto, so the Router
can use this feature as needed, when the Wireless-G products are not able to transmit to the Router in an
environment with heavy 802.11b traffic.
CTS Protection Type. CTS Protection Type specifies the type of traffic covered by the CTS Protection Mode.
Select CTS-only or RTS-CTS from the drop-down menu. If you are not sure which setting to select, then keep
the default setting, CTS-only.
