T-Mobile TM-G5240 Wireless Router User Manual

•Preamble Type - Select Short or Long Preamble. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless network adapters. Auto is the default setting. Note: High network traffic areas should use the shorter preamble type.

•Transmit Power (Mbps) - TM-G5240 has the option to adjust its wireless transmit power. Limiting transmit power can help in situations where you do not want the same signals overlapping one another.

•SSID Broadcast - Enabled is the default setting. Choose Enabled to broadcast the SSID across the network. All devices on the network must share the same SSID (Service Set Identifier) to establish communication. Choose Disabled if you do not wish to broadcast the SSID over the network.

•802.11g Only Mode - For increased speed in your network, enable this option. 802.11b devices will be excluded.

•SPI Mode - Stateful Packet Inspection (also known as dynamic packet filtering) helps to prevent cyber attacks by tracking more state per session. It validates that the traffic passing through the session conforms to the protocol.

•WAN speed to 10/100 Mbps - This option allows the user to select 10Mbps, 100Mbps, or 10Mbps/100Mbps Auto for the Internet port. You may need to change the Internet port speed if you are experiencing connection problems with your Cable, or DSL modem.

•CTS - Clear To Send is a function used to minimize collisions among wireless devices on a wireless local area network (LAN). CTS will make sure the wireless network is clear before a wireless client attempts to send wireless data. Enabling CTS will add overhead and may lower wireless throughput.

Auto - CTS will monitor the wireless network and automatically decide whether to implement CTS based on the amount of traffic and collisions that occurs on the wireless network.

Always - CTS will always be used to make sure the wireless LAN is clear before sending data.

None - CTS is typically used in a pure 802.11g environment. If CTS is set to None in a mixed mode environment populated by 802.11b clients, wireless collisions may occur frequently.
