SoftPerfect WiFi Guard
Online User Manual

Introduction

SoftPerfect WiFi Guard is an essential tool for everyone running a small WiFi network and striving to keep it secure. Generally, modern WiFi networks are well protected, but there are a number of weaknesses that can compromise your WiFi password; this includes vulnerabilities in encryption and brute force attacks. As a result, someone can gain unauthorised access to your Internet and home or office network, exploit them and stay unnoticed.

You may think: “Who cares! I’ve got an unlimited data plan.” But what if someone is reading your personal emails, stealing private information or breaking the law online while using your Internet connection?

Here comes our little app that can alert you whenever your network may be used without your knowledge. WiFi Guard is a specialised monitoring application that runs through your network at set intervals and reports immediately if it has found any new connected devices that could possibly belong to an intruder.

Getting started

If you have not already done so, download a copy of WiFi Guard. Upon its first launch, you will see either the main window, or this configuration dialog if WiFi Guard needs some additional information:

You can leave most settings unchanged, however you must choose your WiFi adapter from the list to let the application know which network it should scan.

The Simultaneous scans setting defines the number of devices scanned in parallel. A higher number will achieve a faster scanning but will use more computer resources, and vice versa. Normally there is no need to adjust this setting.

The Rescan interval (minutes) setting determines how often WiFi Guard should automatically repeat the scan. If you prefer to scan your network only manually, set this number to zero.

You can access and change all these settings at any time later by clicking the Settings button on WiFi Guard’s main application window.

If you have only one adapter, the configuration dialog will not be displayed. Instead you will be presented with the main application window:

The columns display IP and MAC addresses of the detected devices, ping time that shows how long it took the device to respond, automatically detected device names, comments that were added for each device, when each device was first seen, and the device vendors or hardware manufacturers. The line at the bottom shows how many devices are known and unknown, when the next scan is due and which adapter is in use.

Here you can click the Scan Now button, open the Settings, check the Properties of the selected device, or open the Device Catalog of every device ever detected.

If the Scan Now button is disabled, it means that either your network connection is inactive, or an incorrect adapter has been selected. In this case, click the Settings button and try selecting a different adapter from the list.

Scanning your network

Click Scan Now to detect all your network devices. This will scan your WiFi network and display what is there. It may take some time, depending on the size of your network.

Once the scanning process is finished, you will see a list of devices, including your computer, your router and possibly some other devices. Your computer and your router will be marked as “known” (green) straight away, because WiFi Guard already knows they are legitimate. The devices marked “unknown” (red) represent everything else: other computers, smart phones, TV, Xbox, etc. They are red because WiFi Guard doesn’t know yet whether they have your permission to connect to your network.

Automatic detection of new devices

If the Instantly detect new devices joining the network setting on the Scanning page of Settings is enabled, WiFi Guard will automatically and immediately detect every new unknown device connecting to your network. When such a device is detected, you will see an alert message, and the device is scanned straight away and shown in the list in the main application window alongside your other devices.

Identifying your devices

WiFi Guard works by telling your own devices apart from anyone else’s. Once every device you own is marked as “known”, anything new that joins your network stands out straight away.

To mark a device as known, double-click it in the list (or select it and click Properties), tick I recognise this computer or device and click OK. You can also add a comment, such as “Living room TV”, and pick an icon for the kind of device it is:

Marking a device as known

Not sure what a device is? These usually help:

  • Look at its name and vendor in the list. The vendor is the maker of the device’s network chip, so “Apple” usually means an iPhone, iPad or Mac, and a printer or TV maker’s name gives the device away.
  • Think of everything at your place that uses the Internet: phones, tablets, laptops, TVs, games consoles, smart speakers, printers, cameras, smart plugs and light bulbs.
  • Turn a device you suspect off, click Scan Now, and see which one disappears from the list.
  • Click Activity in the device’s properties to see on which days and at what times it has been on your network.

A TV that is on mostly in the evenings and at weekends

Phones and tablets often use a private, randomly generated address for each network, so the same phone can appear as a new device. If you would rather not be alerted about these, tick Automatically mark locally administered addresses as known on the Whitelisting page of Settings.

If a device remains a mystery, change your WiFi password on your router. Your own devices will need the new password, and anything that should not be there will be cut off.

Once you have identified all your devices, the list will look like this, with every device marked green:

List of identified devices

From then on, keep WiFi Guard running: it can start with your computer and rescan your network every 30 minutes or so, and it will alert you whenever a device it does not recognise joins. When that happens, mark the device as known if it is yours, or change your WiFi password if it is not.
