Chapter 5 Configuring the Wireless-G Router Wireless > Advanced Wireless Settings Wireless > Advanced Wireless Settings This tab is used to set up the Router's advanced wireless functions. These settings should only be adjusted by an advanced user as incorrect settings can reduce wireless performance. Advanced Wireless Settings 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 Router but not with each other. To use this function, click Enabled. AP Isolation is disabled by default. 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 Router's rate of data transmission, configure the Transmission Rate setting. Transmission Power The amount of transmission power should be set so that the Router uses only as much power as needed to reach the farthest device in your wireless network. This can help prevented unwanted eavesdropping on your wireless network. You can select from a range of power levels, from Full, Half, Quarter, Eighth, or Min. The default setting is Full. CTS Protection Mode CTS (Clear-To-Send) Protection Mode's default setting is Auto.The Router will automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the Router's ability Wireless-G VPN Router with RangeBooster to catch all Wireless-G transmissions but will severely decrease performance. Beacon Interval The default value is 100. Enter a value between 1 and 65,535 milliseconds. 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 The default value is 3. This value, between 1 and 255, 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. Fragmentation Threshold In most cases, this value should remain at its default value of 2346. It 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. RTS Threshold The RTS Threshold value should remain at its default value, 2347. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, 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.
