SMC Networks SMCWUSB32 instruction

For more secure data transmissions, it is recommended to enable WEP on your WLAN. Click the [Encryption] button to get to this configuration. The utility supports HEX or ASCII key entries. For the HEX Key Format, the security is enabled by entering 10-digit keys for the 64-bit WEP configuration, and 26-digit keys for a 128-bit WEP configuration. For ASCII Key Format, the security is enabled by entering five alphanumeric characters for the 64-bit WEP configuration, and 13 alphanumeric characters for the 128-bit WEP configuration. Select the desired encryption strength (64-bit or 128-bit) and then enter the appropriate keys in Key 1, 2, 3, or 4. Remember to select the correct Default Key. You can also check the "Passphrase" option and enter the desired value. You must be sure to use the same passphrase on all other wireless clients/Access Points.

RTS Threshold

This field allows you to select enable or disable. When the field is set to Enabled, you can adjust the value between 0 to 3000. RTS threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden Node” is a situation in which two stations are within range of the same access point, but are not within range of each other. Thus, it provides a solution to prevent data collisions. However, enabling RTS Threshold may cause redundant network overhead that could negatively affect the throughput performance.

Fragment Threshold

This field allows you to select enable or disable. When the field is set to Enabled, you can adjust the value between 256 to 2346. Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your wireless devices often transmit large files in wireless network, you can enable the Fragmentation Threshold and the mechanism will split the packets being sent.

Section 1.3 Survey

The Survey tab supports a powerful Site-Survey tool to discovery all active wireless devices in the radio range. After selecting this, other wireless devices are displayed on the screen. Users can press the [Connect] button to quickly connect to the wireless device chosen and simultaneously modify the [Default] profile automatically. If users want to update the survey result, they can press [Rescan] button again.
