Wireless Troubleshooting Flashcards
What does throughput refer to?
Throughput: The amount of data successfully transmitted over a network in a given time.
How is network speed defined?
Speed: The rate at which data is transmitted between devices on a network.
What is the significance of distance in networking?
Distance: The maximum range over which data can be transmitted effectively.
What does Received Signal Strength Indication (RSSI) signal strength measure?
Received Signal Strength Indication (RSSI): Measures the power level of a received signal.
What is Effective Isotropic Radiated Power (EIRP)?
Effective Isotropic Radiated Power (EIRP): The total power radiated by an antenna in a specific direction.
What factors should be considered regarding antennas?
Antenna considerations: Type, placement, polarization, and signal strength.
Why is placement important in wireless networking?
Placement: Proper placement is crucial to avoid obstructions and maximize coverage.
What types of antennas are there?
Antenna types: Omni-directional, directional, and parabolic.
What does polarization mean in the context of antennas?
Polarization: The orientation of the radio wave, which affects signal reception.
Why is channel utilization important?
Channel utilization: Efficient use of available channels to avoid interference.
What is AP association time?
AP association time: The time it takes for a device to connect to an access point.
What is a site survey used for in networking?
Site survey: Assesses the wireless environment to optimize AP placement and coverage.
What are common interference issues?
Interference: Caused by other devices or physical obstacles that disrupt signal transmission.
What causes channel overlap?
Channel overlap: Occurs when multiple networks use the same or adjacent channels.
What is antenna cable attenuation/signal loss?
Antenna cable attenuation/signal loss: Loss of signal strength due to cable length and quality.
What causes RF attenuation/signal loss?
RF attenuation/signal loss: Reduction in signal strength as it passes through materials.
What happens if the wrong SSID is used?
Wrong SSID: Prevents devices from connecting to the correct network.
What are the consequences of an incorrect passphrase?
Incorrect passphrase: Blocks access to the network.
What is encryption protocol mismatch?
Encryption protocol mismatch: Causes connection issues due to incompatible security settings.
What can cause insufficient wireless coverage?
Insufficient wireless coverage: Results in dead zones or weak signal areas.
What are captive portal issues?
Captive portal issues: Problems accessing network services due to login or authentication requirements.
What are client disassociation issues?
Client disassociation issues: Devices being unexpectedly disconnected from the network
