Wireless Interference and Signal Strength Troubleshooting

To make sure that all users in your environment receive a strong wireless signal, consider these guidelines when you install your AP devices.The signal strength is the wireless signal power level received by the wireless client.Strong signal strength results in more reliable connections and higher speeds.Signal strength is represented in -dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt.The closer the value is to 0, the stronger the signal. For example, -41dBm is better signal strength than -61dBm.Noise LevelThe noise level indicates the amount of background noise in your environment.If the noise level is too high, it can result in degraded strength and performance for your wireless signal strength.Noise level is measured in -dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt.The closer the value to 0, the greater the noise level.Negative values indicate less background noise. For example, -96dBm is a lower noise level than -20dBm.Signal to Noise RatioThe signal-to-noise ratio (SNR) is the power ratio between the signal strength and the noise level.This value is represented as a +dBm value.In general, you should have a minimum of +25dBm signal-to-noise ratio. Lower values than +25dBm result in poor performance and speeds.For example:If you have a -41dBm signal strength, and a -50dBm noise level, this results in a poor signal-to-noise ratio of +9dBm.If you have a -41dBm signal strength, and a -96dBm noise level, this results in an excellent signal-to-noise ratio of +55dBm.(source: watchguard.com) With the explosion of wireless technology we have experienced in the last few years, wireless networks are being asked to handled more and more demanding traffic. Between laptops, cell phones, and wireless IoT devices, the importance of having your wireless infrastructure optimized has never been greater.In this post hopefully I will be able to help explain some of the concepts used to tune a modern wireless network so that you can become a wireless engineering wizard. Unlike a wired connection, its difficult to see what is going on with your wireless network. To be able to “see” the network we need to use a WiFi analyzing tool. I personally use the Ekahau Sidekick with their wireless survey software at work to get valuable data about my clients networks, but just about all WiFi analysis tool will work.Before we dive into each tuning technique, its important to understand how to read the data. For the purposes of measuring signal strength and noise, wireless analysis tools will usually display this data in terms of decibels (dBm). The way to understand decibel readings is the closer to zero the louder the signal. For instance a reading of -80dBm is a worse signal than -40dBm. Now that we have the tools, lets dive in.Signal StrengthSignal Strength – sometimes called coverage – is the most basic requirement for a wireless network. As a general guideline, low signal strength means unreliable connections, and low data throughput. When optimizing a WiFi network you need to keep in mind the traffic that will use the wireless network. Generally wireless engineers will categorize wireless traffic into either real time data, or bulk data.If the wireless network has to support real time data, such as voice and video traffic, the minimum recommend signal strength should be better than -67dBm. Anything worse and the data rate will drop to a level that will cause delay, and we all know that real time traffic and delay don’t mix. If your wireless network only needs to support bulk data, such as internet traffic or email, then the wireless network can be tuned down to as low as -80dBm before signal strength becomes an issue.As just about everyone knows, the various WiFi protocols have been allocated two frequency bands, 2.4Ghz and 5Ghz. When examining the signal strength of a wireless network its important to remember that the 2.4Ghz band will generally extend farther than

This tutorial will show you how to check the signal strength of your Wi-Fi network connection in Windows 11.Wi-Fi is a wireless local area network (WLAN) technology and standard that uses high-frequency radio waves to provide wireless Internet and network connections to your Windows device.The speed, performance, and reliability of a Wi-Fi network connection depends greatly on its signal strength quality.A weak Wi-Fi signal can lead to slower speeds, dropouts, and disconnection. The further away the device is from the router, the weaker the signal can get. If your walls are made of dense materials (ex: concrete or brick) it will weaken or block a Wi-Fi signal.You must be connected to a Wi-Fi network to check its signal strength.

The network name (SSID) is "WPA3", the ScanSnap cannot be connected. Connect the ScanSnap to the wireless access point using "WPA2" as the security protocol. Ask the manufacturer of the wireless access point whether the security protocol is "WPA2". Are the ScanSnap and wireless access point distant from each other? Also, is there anything that may block the signal (such as walls and metal boards), or an electromagnetic source? The signal between the wireless access point and the ScanSnap is weak, or there may be some signal interference. On the touch panel of the ScanSnap, check the signal status with the icon that is displayed at the top of the home screen. Icon Signal Status Signal strength: Strong Signal strength: Medium Signal strength: Weak No signal Searching for a wireless access point/No wireless access point specified Check the signal status by using ScanSnap Wireless Setup Tool. For details, refer to the ScanSnap Wireless Setup Tool Help. For details about how to start ScanSnap Wireless Setup Tool, refer to Configuring the Wi-Fi Settings. If the signal status is not fine, move the ScanSnap and the wireless access point to different locations. Move the ScanSnap closer to the wireless access point. Move the ScanSnap and the wireless access point away from the following items: Obstacles that may block the signal (for example, walls and metal boards) Devices that may cause signal interference (for example, microwaves and cordless phones) and wireless devices Change the direction of the ScanSnap. HINT Even if the signal status is fine, communication within the range of a certain frequency or in certain wireless channels may become unstable due to signal interference such as noise. When you are in a region where 5 GHz Wi-Fi is available, do not select [Automatic] for the frequency in order to connect the ScanSnap. Select [2.4GHz] or [5GHz] depending on where you use the ScanSnap. For details, refer to Changing the Frequency for Connecting the ScanSnap. Change the value of the wireless channel on the wireless access point if necessary. For details, refer to the manual of your wireless access point. Also, communication in certain wireless channels may become unstable due to signal interference such as noise. Change the value of the wireless channel on the wireless access point. Have you ever set another wireless access point to the ScanSnap? The ScanSnap may be connected to another wireless access point that had been connected before. Display the [Destination setting] window from the Extended Menu of the ScanSnap Wireless Setup Tool, check the wireless access points that are registered, and give the highest priority to the one you want to connect to. For details, refer to the ScanSnap Wireless Setup Tool Help. For details about how to start ScanSnap Wireless Setup Tool, refer to Configuring the Wi-Fi Settings. Are the ScanSnap and the computer communicating via the network? Check whether the ScanSnap and the computer are able to communicate via the network by using the PING command. For details about the checking method, refer The 5Ghz band. As I talked about in my Wireless Fundamentals blog, the 2.4Ghz band has a longer wavelength which allows the signal to travel farther than the shorter 5Ghz band wavelength. Because of this phenomenon, you can’t assume that if the signal strength works well in the 2.4Ghz band that it will work just as well in the 5Ghz band. Make sure to verify both bands with a wireless survey tool.NoiseNoise can be attributed to external factors outside of the wireless space that produces radio noise in the same frequency bands as WiFi. This noise is basically static on the line that can make it difficult for the wireless radios in both the client device and the AP to determine what is data vs what is noise. Some common devices that cause noise in the WiFi wireless frequencies include:Microwave ovensRadarCordless phonesThis list of devices usually surprises people, however both microwave ovens and most cordless phones operate in the 2.4Ghz band. If you get complains of poor wireless performance during lunch, or while talking to customers on a cordless phone, chances are the issue is noise.Signal to Noise RatioSignal-To-Noise Ratio indicates how much the signal strength is stronger than the noise. The signal must be stronger than the noise (SNR greater than zero) for data transfer to be possible. If the signal is only barely stronger than noise, you may encounter occasional connection drop-offs.The way to calculate the ratio is to add the Signal Strength and the noise. The larger the number the better the data rate. Best practice says that a SNR of 20dBm or greater is good. If the ratio isn’t very great you have two options, either increase the signal strength coming from the wireless radios or remove noisy devices.Co-Channel InterferenceChannel interference indicates the number of access points overlapping at each location in a single channel. In dense wireless deployments channel interference can cause network delay. Each of the two bands are split into smaller channels that wireless radios in the APs are assigned to in order to avoid interfering with the neighboring APs.The best example of co-channel interference is with broadcast radio. We have all experienced tuning into a radio station in our car and hit the edge between two separate stations that use the same channel. As a listener you hear both radio stations and it becomes almost impossible to clearly understand either one.In a

NetSpot, which enables minimum advanced features enough for home users and allows personal use only.Network – A wireless local area network is called a WLAN. A wireless network allows two or more devices to communicate using radio waves instead of wires. At its simplest, a wireless network can consist of just a wireless access point (such as a wireless router) and a Wi-Fi-enabled computer. A NetSpot survey can detect the name, strength and channel of all wireless networks and access points within range.Noise – When applied to wireless networks, noise usually refers to other radio waves in the area that interfere with the wireless signal you’re trying to receive. The source of these radio waves can include other Wi-Fi networks, microwave ovens, cordless phones, Bluetooth devices, wireless video cameras, wireless game controllers, and fluorescent lights. A NetSpot survey has the ability to map both the Noise Level and Signal-to-Noise Level in a given area.Overlapping Channels – See signal-to-interference ratio.Project – A NetSpot Project is created every time you start a new Site Survey. Projects can have multiple area maps and Zones. NetSpot Project files are saved with the NetSpot file extension of .netspd.Router – A wireless router is type of wireless access point (AP) that allows a network of wireless devices to communicate. NetSpot can scan an area and identify the quantity and signal strength of all wireless routers within range.Sample Point – or Sampling Point: See Data Point.Scan – NetSpot performs a scan for wireless signals and interference each time you click a spot on the map and create a data point during a Site Survey. The term “scan” is also sometimes used as another name for a Site Survey.Security Type – Wireless networks are protected from unauthorized access by certain security protocols. The most popular are WEP, WPA, WPA2 and WPA3.Signal Level – Wireless signals are transmitted by radio waves. The signal level refers to the strength of those waves, usually measured in decibels (dBm). NetSpot can map the Signal Level, Signal-to-Noise Ratio and Signal-to-Interference Ratio in a given area.Signal-to-Interference Ratio – Similar to the signal-to-noise ratio, this ratio compares the Wi-FI signal level to the level of co-channel interference from other radio transmitters. NetSpot can display the exact ratio at each data point taken, and can display the ratio of individual networks or channels as well.Signal-to-Noise Ratio – This ratio compares the Wi-Fi signal level to the level of background noise. NetSpot can display the exact ratio at each data point taken, and can display the ratio of individual networks or channels as well.Site Survey – A site survey includes all scans taken at a specific site. It can include multiple area maps and Zones. Site surveys are saved as Projects.Survey Name – A site survey name is just a general name that will help you identify the Project you are running, it may contain any characters and may actually be just the name of your client or location. A sample survey name would be “My school”. Signal Strength. The signal strength is the wireless signal power level received by the wireless client.
