A beacon is a packet broadcast by the Router to synchronize the wireless network. The default value is 100. RTS/CTS Threshold: Should you encounter inconsistent data flow, only minor reduction

24 TD-W8901G 54M Wireless ADSL2+ Router User Guide 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. In most cases, keep its default value of 2347. 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 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. 802.11 b/g: In the drop-down list you can select 802.11g (54Mbps) or 802.11b

(11Mbps). "802.11 b+g (54Mbps & 11Mbps)", which allows both 802.11g and 802.11b wireless stations to connect to the Router.
