Configuring the MM2211 Gateway
2. Click Update when you are done.
Configuring WEP Security
1. Click Configuration ->Wireless in the left-hand navigation pane. The window of Figure 7 appears.
2. Select WEP in the Security drop-down menu.
3. Click the Edit Security Settings button.TheWEP Configuration window of Figure 10 appears.
Data Rate Select the desired data rate from the drop-down menu. The default is
Best, which means the system will adjust the data rate automatically.
Transmit Power Select the desired Adapter transmit power from the drop-down menu. We
recommend that you use the default power, Full.
The options are:
•Full
• Half (-3 dB)
• Quarter (-6 dB)
• Eighth (-9 dB)
• Minimum
The default is Full.
Fragment Length The fragment length. The range is between 256 and 2346 bytes. The
default is 2346.
The MM2211 Gateway uses fragmentation to divide 802.11 frames into
smaller fragments which are sent separately to the destination. Only
unicast frames can be fragmented. The fragment length can be between
256-2346 bytes. If the data that the MM2211 Gateway is transmitting is
larger than the threshold, it will trigger the fragmentation function. If the
packet size is equal to or less than the threshold, the gateway will not use
fragmentation. In a good wireless environment, the larger the fragment,
the more efficient the network operates. In a noisy environment, the
fragment length should be adjusted to a smaller size to minimize
retransmission and increase the reliability of the transmission.
RTS/CTS Threshold The RTS-CTS threshold range. The range is between 256 and 2346. The
default is 2346.
The RTS-CTS threshold is a value that determines at what frame length
the request-to-send/clear-to-send (RTS-CTS) function is triggered. By
default, this threshold is set at its highest value. A lower threshold value
means that the RTS-CTS function is triggered for smaller frame lengths.
A lower threshold may be necessary in environments with excessive
signal noise or hidden nodes; but this may result in some performance
degradation.
