Wireless Tab / Advanced Wireless Settings


This tab is used to set up the Router advanced wireless functions. These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance.

 

AP Isolation

AP Isolation creates a separate virtual network for your wireless network. When this feature is enabled, each of your wireless client will be in its own virtual network and will not be able to communicate with each other. You may want to enable this feature if you have many guests that frequent your wireless network. The default setting is Disabled.
 
 

Authentication Type

The default is set to Auto (Default) authentication.  With Open System authentication, the sender and the recipient do NOT use a WEP key for authentication. With 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 Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will be used. The Router will also advertise that it will automatically select the best rate for transmission. The default setting is Default, when the Router 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 Router can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the Routerís rate of data transmission, configure the Transmission Rate setting.

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 Router automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Router and a wireless client. The default value is Auto.

N Transmission Rate

Transmission Rate for Wireless-N.

CTS Protection Mode

CTS (Clear-To-Send) Protection Mode function boosts the Wireless Routerís ability to catch all wireless transmissions, but will severely decrease performance. Keep the default setting, Auto, so the Wireless Router can use this feature as needed, when the Wireless-N/G products are not able to transmit to the Wireless Router in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature.
 
 

Beacon Interval

The default value is 100. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network.

DTIM Interval

This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1.

Fragmentation Threshold

This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.

RTS Threshold

Should you encounter inconsistent data flow, only minor reduction of the default value, 2346, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2346.
