NetSpot Review – Wi-Fi survey app for Windows

In this three part series we review NetSpot a Wi-Fi survey app for Mac and Windows.

In this part, we look at the Microsoft Windows version of NetSpot.  NetSpot performs accurate Wi-Fi surveys that allows you to use a map of your business, industry or home with dozens of other features.

NetSpot’s Discover Mode collects details about surrounding Wi-Fi networks and returns the data in a detailed table that provides information about the SSID, MAC address, Channel, Security, Vendor, Signal Information (including Average, Max and Min.).  This app also gives you Noise levels for wireless professionals to calculate an exact signal strength.  The real-time charts gives accurate information about 2.4 and 5Ghz frequencies.  NetSpot allows you to download historical information in a CSV file for accurate record keeping.  (More information on Discover Mode will follow in this series.)

The application can be downloaded from here.   The download is a tiny 1.2mb download.  The installation and operation is easy.

Operating the software in Survey Mode is easy.  Simply open the application, upload your map (selecting your approximate measurement) and start your survey by standing near your AP after selecting it, wait a few seconds and then click your mouse.   An accurate signal and information about the AP will give you a heatmap of the immediate area overlaying the information on the map.

To insure an accurate signal is measured it is import to stand in the area for a few seconds then click your mouse.   During our survey, we took several screenshots to show the accuracy of the application as we performed a very basic survey.

Given more time, and more mouse clicks, the accuracy of the survey will of course go up.

During the review, we used two identical laptops with identical drivers and operating systems (Windows 10).  With two individuals using NetSpot, you’ll find the accuracy of the initial survey between the screenshots below is very similar.

The individuals walked side by side to compare readings throughout the survey.

Laptop 1 (Titled Laptop Four 1 of 4 laptops assigned to the  area)



Laptop Two




As you can see, this application is a critical application in today’s world because of wireless connectivity growth and complexity.  This application helps to show coverage area and is an important tool for IT professionals when verifying and troubleshooting your wireless connectivity.

Look for parts two and three in the upcoming weeks.  We will update this post and link each post as time permits.

NEW – Software Downloads Page (with hundreds of titles — updated daily)

Excellent! Great resource.

What's On My PC

Just did a revamping of the software Downloads Page…  The page consists of feeds from numerous reputable software and app sites that primarily specializes in FREE software. I am currently using this as my “go to” source to review software listings and to see what is new and/or has been updated. The list is very, very long…  If you hover your mouse pointer over a software title that interests you, a floating description will appear.

Windows Cleanup shows 3.99TB? Is my math wrong?

Apparently there is a bug that shows 3.99TB of Windows Update Cleanup when you run the disk cleanup application in Windows 10.  With the plethora of updates that Microsoft has thrown at everyone, this would seem about right, however, you can’t clean 3.99TB from a 1TB disk.

Although I’m sure my disk is OK since the entire internet is reporting this.  It’s a good time to run a chkdsk just to be sure if you receive this.  The odds are that the app is reporting the 3.99TB falsely.

OWASP Zed Attack Proxy (ZAP)- Using on your home network

OWASP -The Open Web Application Security Project is an online community which creates freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security. (Wikipedia)

If you have wanted to learn how to test your network and the devices, you can begin with OWASP Zed Attack Proxy (ZAP).  Remember, when you get ready to attack, you must own the network and the devices on the network.

You can download OWASP Zed Attack Proxy from the link above.

Once you install the program, you may want to make exceptions in your anti-virus or anti-malware software. Plug-ins may be detected as viruses, however, this is common with security software.


Once you have installed OWASP Zed Active Proxy, you may want to update and add some components.  If you are new at scanning and testing security, be sure to look at the tutorials and OWASP videos below.  Again, make sure you own the network and devices on the network.



You now need targets.  Start with things such as your router or other devices on your network.  A good way to find them is to use Netscan or Softperfect’s Wi-Fi Guard.

Here’s a basic list of some of the devices on my home network.


  • Open OWASP Zed Attack Proxy (basic scan)
  • Enter the IP address to attack
  • Click on Attack


  • Attacks are entered into the URL box in the right pane (above)


  • View the alert information by selecting the tab (above)


  • Look at spider information by selecting the appropriate tab. (above)
  • You can view the history of an attack. (below)


  • Below- You can right click and open links with a browser (dozens of more features)


  • Go to Reports and Export as HTML – This will give you links and information on the vulnerabilities of the device. (below)


Basics and other videos (found in the links below)

DHCP issues with KB3201845

If you have issues after applying KB3201845, Rick over at Whats On My PC may have first found it.  Apparently Microsoft is displaying a banner on their Windows 10 History page that says to restart NOT shutdown.   We experienced the issue Friday thinking a DNS issue had appeared – however, after his clues on restarting, we made sure the KB was on and restarted the affected machines – fixing whatever issue appeared with the KB.

The KB is a little over 900mb which is beginning to tax our resources (huge updates).  While we use a WSUS server, computers that receive the update and shutdown may ‘see’ the problem.  Here’s a link to the KB for a full download if you have a lot of computers.

From the History site –

Seagate GoFlex Home Server firmware update issues – solved

Several years ago we did a review on Seagate GoFlex Home Server (NAS).  Recently I went to update the firmware which can be found in the web interface of the device.


Once I clicked ‘update’,  the device found an update but would not download the update.  Searching with Google’s Chrome I found the updated firmware at .

The site was for some reason marked malicious by Google.  Here’s how to fix the issue.

  • First, login to your device and note every user of the device so that your original files will be maintained.  While the device will flash, it is important to recreate your original users or you can lose your files.
  • Open    with Edge or Internet Explorer.
  • Download the zipped file with IE or Edge from the site above
  • Format a USB key with FAT32
  • Extract the Zipped files to the USB key at the root level. No other files should exist on the USB key.
  • Gracefully remove the USB key from the PC and insert into the GoFlex Home’s USB connector.
  • Power off your GoFlex Home, ensure power cord and Ethernet are still connected.
  • Remove the hard disk from the GoFlex Home.
  • With your GoFlex Home powered off, press the Power button and hold the Reset pin. The green light will blink immediately, followed by the white light. Release the reset pin and wait for the device to complete booting and obtains a steady green light (approximately 3-4 minutes) – Be Patient!
  • Your device should now be reflashed, remove the USB key
  • Power the device off
  • Reinsert the HDD
  • Power the device on
  • Log into the device
  • Recreate one of the administrator users you had before flashing
  • Once you login, recreate the other users you had

Uninstall Old Drivers and Speed Up Your Computer

One of the best ways to speed up your computer of course is to uninstall old programs.   A recent article showed that the installation of multiple programs on any computer could slow the computer’s boot time, response time and even the shutdown.

Just like programs;  installing network cards, video cards, wireless cards, usb drives and other hardware and even software will put drivers in your computer.  These non existent devices can be seen in the device manager by going to a command prompt as an administrator and typing – set devmgr_show_nonpresent_devices=1

Then open the device manager and click on View and Show Hidden Devices.  You will then see ‘faded’ devices that are still loading in the device manager.   These devices are hardware and/or software (yes, even software will load drivers that control hardware) that no longer are installed on your computer.

Note:  In regards to the software drivers – even if you uninstall the software many antivirus programs and firewalls leave junk behind.

Always use caution when removing drivers, editing the registry or working with any configuration that changes your system.

Go through these devices and remove any older hardware you know no longer exist.  Rebooting your computer should result in a quicker response time.
