DSL-G604T Generation II ADSL2+ Wireless Modem Router
Description
Beacons are emitted from the router in order to synchronize the wireless network. You
may set the Beacon Interval range between 20-100 microseconds per beacon sent. The
default is 100.
DTIM (Delivery Traffic Indication Message) Period is a countdown informing clients of the
next window for listening to broadcast and multicast messages. The default setting is 3.
Choose Enabled to STOP broadcasting the SSID across the network. When this is
enabled, the SSID willl be hidden from roaming devices. Choose Disabled if you want to
broadcast the SSID over the network.
Allows the user to adjust the transmit power of the router. A high transmit power allows
a greater area range of accessibility to the router. When multiple overlapping access
points are present, it may be desirable to reduce transmition power.
The RTS (Request to Send) Threshold controls the size of data packets issued to a RTS
packet. A lower level will send packets more frequently which may consume a great
amount of the available bandwidth. A high threshold will allow the router to recover from
interference or collisions which is more prevalent in a network with high traffic or high
electromagnetic interference. The default setting is 2347.
The fragmentation threshold will determine if packets are to be fragmented. Packets over
the 2346 byte limit will be fragmented before transmission. 2346 is the default setting.
The access point can be forced to operate in g mode or b mode to associate with
exclusively 802.11b or 802.11g devices. Additional options include b+ and g+, these are
enhanced higher speed operation modes for 802.11b and 802.11g devices that support it.
When User Isolation is enabled, peer-to-peer communication is disabled. This prevents
unicasts from one wirless station to another in the same BSS.
Select to enable wireless QoS priority (IEEE 802.11e) support.
