¾Access point Settings: These are the settings of the access point. You can configure the rules to allow wireless-equipped computers and other devices to communicate with a wireless network.

•Access point: Select Activated to allow wireless station to associate with the access point.

•Channel: Select your region and the channel you want to use from the drop-down List of Channel. This field determines which operating frequency will be used. It is not necessary to change the default channel unless you notice interference problems with another nearby access point.

•Transmit Power: Here you can specify the transmit power of modem router. You can select High, Medium or Low which you would like. High is the default setting and is recommended.

•Beacon Interval: Enter a value between 20-1000 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the modem router to synchronize the wireless network. The default value is 100.

•RTS/CTS Threshold: 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 modem 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. In most cases, keep its default value of 2347.

•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.

•DTIM: 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 modem 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.

•Wireless Mode: In the drop-down list you can select “802.11b”, “802.11g”, “802.11n”, “802.11b+g”, “802.11g+n” and “802.11b+g+n”. “802.11b+g+n” allows 802.11b, 802.11g and 802.11n wireless stations to connect to the modem router.
