WIFI WEP VS WPA OVERHEAD SOFTWARE

It is possible for interference to be so bad that you don't see high packet error rates because you don't even recognize incoming packets - this can be verified by comparing the number of packets sent by the AP to the number of packets received by wireless client. Signal quality may even acceptable, since interference may be intermittent. A signal strength indicator may report the signal as 'good' with interference. If your packet error rate is high (over 10%), you are probably experiencing interference. Preamble Mode: Long Preamble allows extra time for the Digital Decoder to process the packets. Setting this parameter to a large value decreases the available bandwidth during periods of interference, but makes the system more immune to interference and collisions that can occur in environments with obstructions or metallic surfaces that create complex multi-path signals. RTS Retry Limit: Specifies the number of times the client adapter resends a request-to-send (RTS) packet if it does not receive a clear-to-send (CTS) response. However, small values help the system recover from interference or collisions, which can occur in environments with obstructions or metallic surfaces that create complex multi-path signals. A small value causes RTS packets to be sent more often, which consumes more of the available bandwidth and reduces the throughput of other network packets. RTS Threshold: Specifies the data packet size beyond which the low-level RF protocol invokes RTS/CTS flow control. Setting the Fragmentation Threshold too low may result in very poor performance. If you experience a high packet error rate try to slightly increase your Fragmentation Threshold. Fragmentation generally reduces throughput because the packet overhead for each fragment consumes a higher portion of the RF bandwidth. If a single fragment experiences interference during transmission, only that fragment must be resent. When the network protocol supports retries, the application can decide whether or not to retransmit the packet.Р”Р‡RAGMENTATION THRESHOLD: Defines the largest RF packet that the client adapter sends without splitting the packet into two or more smaller fragments. If your network uses a protocol that supports retries, set Data Retries to a value smaller than the default. ED or Car/Cor-Identifies a busy channel by detecting either an RF energy above the ED threshold or a DSSS signal.Р”ВATA RETRIES: the number of times a packet is resent if the initial transmission was unsuccessful. Energy Detect (ED)-ED identifies a busy channel by detecting any RF energy above the ED threshold.Р”В. This signal may be above or below the Energy Detect (ED) threshold.Р”В¬. Carrier/Correlation (Car/Cor)-CCA identifies a busy channel by detecting a direct-sequence spread spectrum (DSSS) signal.

World mode: uses passive scanning (listen only), which increases the time that it takes the client adapter to connect.Р”В¬lear Channel Assessment: Specifies how the client adapter identifies a clear channel before it transmits data using either:Р”Р„.

TX POWER: Effects the transmit range of the radio signal. *note: some manufactures use different names for various settings.Р”РЋ(B) or 6(G) Mbps Provides the greatest range but the lowest throughput.Р”РЋ1(B) or 54(G) Mbps Provides the greatest throughput but the lowest range. Cisco's 'Aironet client monitor' seems to have the most adjustable fields and also monitors network statistics.

And 'Clients' are typically roaming between access points and varying levels of signal strength and quality, the 'optimum' values to use can vary.Р”Вepending upon the equipment you are using and which wireless management software that you have, you may not have the option of manually adjusting some of these settings. Since Wi-FI networks tend to be susceptible to interference & dead spots.
