Wifi Signal Strength 1.9 macOS 6 mb WiFi Wireless Signal Strength Explorer (was WiFi Signal Strength Status) allows you to see wireless signal strength right on the menu bar. See the status of your wifi signal strength right from the menu bar. OK so it seems lots of us are having this wi=fi keeps dropping issue but i kinda found a solution to that problem. I bought an Aspire E 15 and relised the wi fi signal keep dropping to 1bar or 2bars. Sometimes it even goes off completely and i have to connect again, was driving me nuts. All other laptops in the house were connecting.even my phone was enjoying internet access except my acer.

3. Determine Signal Strength Of Home Wifi

Wireless internet is everywhere these days and you could have several WiFi capable devices connected to your own wireless network. Because of that it’s important the WiFi router is placed in the best available location to give the longest range and strongest signal to as many devices as possible. If the router is placed in a poor location the signal could be weak, intermittent or cause constant dropouts.

There are many factors that can affect the quality and strength of a WiFi network connection. These include walls, floors, ceilings, electrical appliances, anything emitting radiation or electromagnetism, and of course distance to the router. Windows and most bundled WiFi software allows you to see how good the current wireless signal is. To get a better idea how the signal is behaving and whether it gets affected by other factors it’s a good idea to monitor the signal strength over a period of time.

Watching how your WiFi signal behaves over several minutes or even hours could help identify if the current location for it is ideal or causing problems. Here we list 5 free tools that show a graph for your wireless signal so you can watch it over a period of time to see how it behaves.

1. NetSpot

NetSpot is a free wireless network signal analysis and troubleshooting tool available for both Mac and Windows computers. In addition to a standard WiFi discovery and monitoring section it also has a site survey feature that allows for the relative network signal strengths to be plotted onto a map of your building or local area.

The program starts in Discover mode which shows available wireless networks along with some general statistics. Double click on the target network to open the details window. This has a Signal tab which shows a graph of the signal strength over a period of time, the last 5, 30, or 60 minutes can be shown in the window at once. Also available is a Tabular Data window that shows the same data as the graph but in text form.

The frequency of the signal strength scanning can be either left at the default of 5 seconds or changed to 10, 30 or 60 seconds. Do be aware that NetSpot crashed for us on first run but appeared to work fine after a system reboot.

2. inSSIDer

The sad thing about inSSIDer is it stopped being free and became a shareware application from version 3 onwards. Luckily version 2 remains free and open source although it’s not had any updates since 2012 and compiled versions with the free source code are a bit hard to find.

After installing and running the program click the Time Graph tab to see the signal strength graphs for all found wireless networks. Uncheck those you don’t want to appear in the graph display to be left with the signals to be monitored. The display shows signal strength over a period of 5 minutes and any selected SSID will be shown in bold. Although you cannot view the signal for more than the 5 minutes you can right click on the graph and copy an image of it to the clipboard for a snapshot record. This can in turn be pasted into a paint program.

3. Homedale

Homedale has a big advantage over the other tools here because it’s the only one that is completely portable, which many people prefer. The program is well laid out and easy to use. Besides the signal graphs you can also get your location at the click of a button from a mapping service such as Google.

Monitoring a wireless network is a simple case of going into the Access Points tab and double clicking on the access point. Its icon will turn red to signify it has been selected and you will be shown the current signal strength graph. The graph itself refreshes every 2 seconds by default and shows about 20 minutes worth of signal history. The refresh rate can be changed from the Options tab to 1, 5, 10, 30 or 60 seconds. Right click to save the current graph as an image or start logging the history data to a text file.

Homedale also supports a few command line switches so you can launch it to start monitoring and logging a specified network automatically. Use /? in a Command Prompt to get a list of arguments that can be used. For example the following will create a log.txt and add a signal strength entry every 3 seconds for the SSID Raymondcc_WiFi.

Homedale -s Raymondcc_WiFi -l log.txt -r 3000

4. Acrylic Wi-Fi Home

The Home version of Acrylic Wi-Fi is free for personal use and has enough to show a signal strength graph for monitoring or troubleshooting. One useful feature missing and only available in the paid Pro version is the ability to alter the timeline of the signal strength graph from the default of 5 minutes to 1, 3 or 10 minutes.

On install and launch click Options (3 horizontal lines) and choose Advanced Mode to make the graph full width and remove the useless Pro only network quality pane. To remove a wireless network from the graph click on the color block to the left of its name in the SSID list. The graph is colored into good and not so good strengths, highlighting an SSID will bold it for easier viewing, Microsoft .NET 4.5 is required which will need to have been installed on Windows 7 or Vista. Visual C++ 2012 Redistributables are also required.

5. Vistumbler

This tool has a few quite advanced options such as GPS support, live Google Earth tracking and a number of experimental features. More standard functions include getting WiFi signal strength and information as well as the ability to audibly speak out the signal strength to you.

Wifi Signal Strength Meter

You don’t really have to do much to get the strength information after installation, simply click Scan APs and click on Graph 1 or Graph 2. Then click on a wireless network in the list to populate the graphs. The first is a simple line that measure signal strength over a few minutes. The second is a bar graph (pictured above) which shows the signal strength history for around 11 minutes. Changing the Refresh loop in Settings > Misc Settings to another value from the default of 1000ms (1 second) will lengthen or shorten the graph history time.

Download Vistumbler

We did also look at Xirrus WiFi Inspector and NetSurveyor although both don’t log wireless signals for very long. Xirrus also requires you to fill in an online form to get the download link from the website.

Tried netspot inssider and homedale. It seems that homedale is the only one who will log signal stregth for long period of times (indefinitely?) in the log file.

Go to access points and double click your router
go to access point graph right click and ask to log, you need to specify a file name

The log file is very simple and has the format yy-mm-dd hh:mm:ss: .
you can select the whole text, past it to, say, google sheets and write in an empty cell the formula =min(b:b), it’ll show the min power value of the log file

Homedale create a file named oui.txt inside its residing folder which is very annoying.
Every time you close the program you have to delete this file manually, it consumes
about 2M of disk space.

Thanks looks well done and there are some other nice utilities at the site.

Planning

The key to any good wireless deployment is proper planning, which requires a set of goals and requirements to achieve. Determining minimum signal strength requirements in the coverage area is almost alway part of the network requirements list.

Requirements and Variables

Desired signal strength for optimal performance varies based on many factors, such as background noise in the environment, the amount of clients on the network, what the desired data rates are, and what applications will be used. For example, a VoIP or VoWiFi system may require much better coverage than a barcode scanner system in a warehouse.

Understanding Signal Strength

WiFi signal strength is tricky. The most accurate way to express it is with milliwatts (mW), but you end up with tons of decimal places due to WiFi's super-low transmit power, making it difficult to read. For example, -40 dBm is 0.0001 mW, and the zeros just get more intense the more the signal strength drops.

RSSI (Received Signal Strength Indicator) is a common measurement, but most WiFi adapter vendors handle it differently, as it isn't standardized. Some adapters use a scale of 0-60, and others 0-255.

Ultimately, the easiest and most consistent way to express signal strength is with dBm, which stands for decibels relative to a milliwatt. Since RSSIis handled differently by most WiFi adapters, it's usually converted to dBm to make it consistent and human-readable.

• mW - milliwatts (1 mW = 0 dBm)
• RSSI - Received Signal Strength Indicator (usually 0-60 or 0-255)
• dBm - Decibels in relation to a milliwatt (usually -30 to -100)

Determine Signal Strength Of Home Wifi

Reading dBm

The first thing to understand about dBm is that we're working in negatives. -30 is a higher signal than -80, because -80 is a much lower number.

Next, it's important to know that dBm does not scale in a linear fashion like you'd expect, instead being logarithmic. That means that signal strength changes aren't smooth and gradual. The Rule of 3s and 10s highlights the logarithmic nature of dBm:

3 dB of loss = -3 dB = halves signal strength
3 dB of gain = +3 dB = doubles signal strength
10 dB of loss = -10 dB = 10 times less signal strength (0.1 mW = -10 dBm, 0.01 mW = -20 dBm, etc.)
10 dB of gain = +10 dB = 10 times more signal strength (0.00001 mW = -50 dBm, 0.0001 mW = -40 dBm, etc.)

Ideal Signal Strength

So what signal strength should you shoot for? For simple, low-throughput tasks like sending emails, browsing the web, or scanning barcodes, -70 dBm is a good signal strength. For higher-throughput applications like voice over IP or streaming video, -67 dBm is better, and some engineers recommend -65 dBm if you plan to support mobile devices like iPhones and Android tablets.

Note: The numbers in this chart are suggestions only. The desired signal strengths will vary, based on the requirements for the network.

Signal Strength	TL;DR	Required for
-30 dBm	Amazing	Max achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable in the real world.	N/A
-67 dBm	Very Good	Minimum signal strength for applications that require very reliable, timely delivery of data packets.	VoIP/VoWiFi, streaming video
-70 dBm	Okay	Minimum signal strength for reliable packet delivery.	Email, web
-80 dBm	Not Good	Minimum signal strength for basic connectivity. Packet delivery may be unreliable.	N/A
-90 dBm	Unusable	Approaching or drowning in the noise floor. Any functionality is highly unlikely.	N/A

Tracking Signal Strength

Signal strength is easy to track with inSSIDer. Configure the signal strength threshold to whatever signal strength you require, select your network, and walk the desired coverage area.

If the blue line falls below the dotted line, you know you have a dead spot. That's it!
