In this section, we will show you how to troubleshoot some of these common problems and how to use Cisco tools and resources for troubleshooting.
Troubleshooting RF Communication Problems
The most common cause of wireless problems is RF communication problems, which can affect both data transmission and reception between your wireless access point and other devices on the network. RF communication problems can be caused by interference, noise, attenuation, reflection, multipath, or hidden node issues. To troubleshoot RF communication problems, you need to check the following aspects:
Interference
Interference is any unwanted signal that disrupts or degrades the quality of your wireless signal. Interference can come from various sources, such as other wireless devices, microwave ovens, cordless phones, Bluetooth devices, or nearby access points using the same or overlapping channels. To troub leshoot interference problems, you need to do the following:
Identify the source and type of interference using a spectrum analyzer or a wireless scanner tool, such as .
Avoid or minimize the interference by changing the channel, frequency, or location of your wireless access point or the interfering device.

Noise
Noise is any unwanted signal that adds to the background level of your wireless signal. Noise can come from various sources, such as electrical devices, power lines, fluorescent lights, or environmental factors. Noise can affect the signal-to-noise ratio (SNR) of your wireless signal, which is the difference between the signal strength and the noise level. A low SNR can result in poor wireless performance, such as low data rates, high error rates, or lost packets. To troubleshoot noise problems, you need to do the following:
Measure the noise level and SNR of your wireless signal using a wireless scanner tool, such as .
Reduce the noise level by removing or shielding the noise source, or by moving your wireless access point or client away from the noise source.
Increase the signal strength by using higher-gain antennas, adjusting the antenna orientation, or increasing the transmit power of your wireless access point or client.
Use features such as clear channel assessment (CCA), carrier sense multiple access with collision avoidance (CSMA/CA), or request to send/clear to send (RTS/CTS) to avoid transmitting when the channel is noisy.
Attenuation
Attenuation is the loss of signal strength as it travels through a medium, such as air, walls, floors, ceilings, or windows. Attenuation can affect the range and coverage of your wireless signal, as well as the data rate and quality. Attenuation can vary depending on the frequency, distance, and material of the medium. To troubleshoot attenuation problems, you need to do the following:
Measure the signal strength and data rate of your wireless signal using a wireless scanner tool, such as .
Reduce the attenuation by reducing the distance between your wireless access point and client, or by using repeaters, extenders, or mesh networks to extend your wireless coverage.
Avoid or minimize obstacles that block or absorb your wireless signal, such as metal objects, concrete walls, water pipes, or furniture.
Use features such as antenna diversity, spatial multiplexing, or beamforming to improve your wireless signal quality and reliability.
Reflection
Reflection is the bouncing of your wireless signal off a surface, such as a wall, ceiling, floor, window, or mirror. Reflection can affect the phase and direction of your wireless signal, which can cause constructive or destructive interference. Constructive interference occurs when two signals add up to create a stronger signal. Destructive interference occurs when two signals cancel out each other to create a weaker signal. To troubleshoot reflection problems, you need to do the following:
Measure the phase and direction of your wireless signal using a spectrum analyzer or a wireless scanner tool, such as .
Avoid or minimize reflective surfaces that cause unwanted reflections of your wireless signal.
Use features such as antenna diversity a>
].
Avoid or minimize multipath effects by reducing the distance between your wireless access point and client, or by using directional antennas or repeaters to create a more direct path.
Use features such as MIMO, spatial multiplexing, or beamforming to exploit multipath effects and increase your wireless performance and reliability.
Use features such as channel equalization, rake receivers, or orthogonal frequency-division multiplexing (OFDM) to compensate for multipath effects and reduce errors and distortion.
Hidden Node
A hidden node is a wireless device that is out of range or hidden from another wireless device, but is within range of a common wireless access point. A hidden node can cause collisions and contention on the wireless channel, which can result in poor performance, low throughput, or dropped connections. A hidden node problem can occur when your wireless access point or client is located in a corner, behind an obstacle, or too far away from other devices. To troubleshoot hidden node problems, you need to do the following:
Measure the signal strength and quality of your wireless signal using a wireless scanner tool, such as .
Reduce the hidden node problem by increasing the signal strength and quality of your wireless access point or client, or by reducing the number of devices on the same channel.
Use features such as RTS/CTS or CTS-to-self to prevent collisions and contention on the wireless channel.
Use features such as load balancing, band steering, or channel selection to distribute the traffic and avoid congestion on the wireless channel.

Move your antenna to change the distance or angle of your wireless signal. For example, if you want to extend your range, you might want to move your antenna higher or closer to the edge of the coverage area. If you want to reduce interference or noise, you might want to move your antenna away from the source of interference or noise.
The Cisco Aironet 1040 Series wireless access point has two integrated omnidirectional antennas that are fixed in position and cannot be tilted or rotated. However, you can move the entire device to change the location of the antennas. You can also use external antennas that can be tilted or rotated independently, depending on your coverage needs. For more information on how to install and adjust external antennas, you can refer to the .
Adjusting Transmit Power, Data Rate, and Channel Width
The transmit power, data rate, and channel width of your radio affect the performance and reliability of your wireless signal. You can adjust them by changing some settings on your wireless access point or controller. To adjust your transmit power, data rate, and channel width for your Cisco Aironet 1040 Series wireless access point, you need to do the following:
Use a wireless scanner tool, such as , to measure the transmit power, data rate, and channel width of your wireless signal in different locations and directions.
Adjust the transmit power of your radio to change the range and coverage of your wireless signal. For example, if you want to increase your range and coverage, you might want to increase your transmit power. If you want to reduce interference or noise, you might want to decrease your transmit power.
Adjust the data rate of your radio to change the speed and quality of your wireless signal. For example, if you want to increase your speed and quality, you might want to use a higher data rate. If you want to increase your reliability and compatibility, you might want to use a lower data rate.
Adjust the channel width of your radio to change the bandwidth and capacity of your wireless signal. For example, if you want to increase your bandwidth and capacity, you might want to use a wider channel width. If you want to reduce interference or noise, you might want to use a narrower channel width.

You can adjust the transmit power, data rate, and channel width of each radio independently, depending on your performance needs. You can also use features such as dynamic transmit power control (DTPC), automatic rate selection (ARS), or channel bonding to optimize your wireless performance automatically. For more information on how to adjust these settings, you can refer to the .
Using Mesh Deployment Modes and Beamforming Technologies
Besides optimizing your antennas and radios, you can also use some advanced features and technologies that can enhance your wireless coverage, mobility, connectivity, and stability. These features and technologies include mesh deployment modes and beamforming technologies. To use these features and technologies for your Cisco Aironet 1040 Series wireless access point, you need to do the following:
Using Mesh Deployment Modes
A mesh deployment mode is a way of connecting multiple wireless access points without using wired connections. A mesh deployment mode can extend your wireless coverage, increase your network redundancy, and improve your network flexibility. A mesh deployment mode consists of two types of wireless access points: root access points (RAPs) and mesh access points (MAPs). RAPs are connected to the wired network and provide wireless connectivity to MAPs. MAPs are not connected to the wired network and provide wireless connectivity to clients and other MAPs.
To use a mesh deployment mode for your Cisco Aironet 1040 Series wireless access point, you need to do the following:
Configure one or more RAPs on your network using a wireless controller or an autonomous software.
Configure one or more MAPs on your network using a wireless controller or an autonomous software.
Associate the MAPs with the RAPs using a secure mesh link.
Configure the mesh parameters such as channel assignment, transmit power, data rate, security, quality of service (QoS), and load balancing.
The Cisco Aironet 1040 Series wireless access point supports both indoor and outdoor mesh deployment modes. You can use either the 2.4 GHz or the 5 GHz band for the mesh link, depending on your interference and performance needs. You can also use features such as adaptive wireless path protocol (AWPP), fast secure roaming (FSR), or hybrid remote edge access point (H-REAP) to optimize your mesh performance and reliability. For more information on how to configure a mesh deployment mode, you can refer to the .
Using Beamforming Technologies
A beamforming technology is a way of directing your wireless signal toward a specific receiver using multiple antennas. A beamforming technology can improve your wireless signal strength, quality, range, and reliability. A beamforming technology consists of two components: a transmitter that uses multiple antennas to send out signals in different directions, and a receiver that uses multiple antennas to receive signals from different directions.
To use a beamforming technology for your Cisco Aironet 1040 Series wireless access point , you need to do the following:
Choose a beamforming technology that is compatible with your wireless access point and client. There are two types of beamforming technologies: explicit and implicit. Explicit beamforming requires both the transmitter and the receiver to support the same beamforming standard, such as 802.11n or 802.11ac. Implicit beamforming does not require the receiver to support the same beamforming standard, but it is less effective and accurate than explicit beamforming.
Enable the beamforming feature on your wireless access point and client. You can do this by changing some settings on your wireless controller or software. For example, you can enable or disable explicit or implicit beamforming, or you can adjust the beamforming gain or feedback interval.
Verify that the beamforming feature is working properly by measuring the signal strength, quality, range, and reliability of your wireless signal using a wireless scanner tool, such as .
