Wireless-N ADSL2+ Gateway

The Advanced Wireless Settings Tab

This tab is used to set up the Gateway's advanced wireless functions. These settings should only be adjusted by

an expert administrator as incorrect settings can reduce wireless performance.

Advanced Wireless

• AP Isolation. This isolates all wireless clients and wireless devices on your network from each other. Wireless

devices will be able to communicate with the Gateway but not with each other. To use this function, click

Enabled. AP Isolation is disabled by default.

• Authentication Type. The default is set to Auto, which allows either Open System or Shared Key

authentication to be used. Select Shared Key if you only want to use Shared Key authentication (the sender

and recipient use a WEP key for authentication).

• Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the

Gateway can transmit. The Gateway will advertise its Basic Rate to the other wireless devices in your

network, so they know which rates will be used. The Gateway will also advertise that it will automatically

select the best rate for transmission. The default setting is Default, when the Gateway can transmit at all

standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for

use with older wireless technology, and All, when the Gateway can transmit at all wireless rates.

• Transmission Rate. 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 select Auto to have the Gateway

automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will

negotiate the best possible connection speed between the Gateway and a wireless client. The default setting

is Auto.

• N Transmission Rate. The rate of data transmission should be set depending on the speed of your Wireless-N

networking. You can select from a range of transmission speeds, or you can select Auto to have the Gateway

automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will

negotiate the best possible connection speed between the Gateway and a wireless client. The default setting

is Auto.

• CTS Protection Mode. CTS (Clear-To-Send) Protection Mode's default setting is Auto. The Gateway will

automatically use CTS Protection Mode when your Wireless-N and Wireless-G products are experiencing

severe problems and are not able to transmit to the Gateway in an environment with heavy 802.11b traffic.

This function boosts the Gateway's ability to catch all Wireless-N and Wireless-G transmissions but will

severely decrease performance.
