CommView for WiFi: Legal Ways to Analyze Wi-Fi Networks and Why Hacking Is Prohibited

Program CommView for WiFi is often mentioned in the context of wireless network security testing, but its capabilities are often interpreted in an extremely simplified manner. In practice, it is a professional tool for packet monitoring, traffic analysis and vulnerability detection in own networks. However, you can find dozens of guides online that position it as a "universal key" for accessing other people's Wi-Fi. This is not only technically questionable, but also is punishable under Article 272 of the Criminal Code of the Russian Federation ("Unauthorized access to computer information").

In this article we will look at how CommView for WiFi It really works: from packet capture to handshake decryption, but with an emphasis on legal use — audit your network, find encryption weaknesses, and protect against real-world attacks. You'll learn what data can be extracted from the airwaves without breaking the law and why. WPA3 harder to hack than WEP, and how attackers exploit protocol vulnerabilities. We'll also explain why most "hacking instructions" found online are either outdated or simply don't work on modern routers.

If you're looking to improve your home Wi-Fi security, this article will help you understand the tools and techniques used by both hackers and cybersecurity professionals. If you're looking to connect to someone else's network, be aware: not only is it illegal, but it's also extremely difficult to do without a thorough understanding of network protocols and cryptography.

What is CommView for WiFi and how does it work?

CommView for WiFi — is a software traffic analyzer developed by the company TamoSoft. It allows you to capture data packets transmitted over wireless networks in the monitoring (monitor mode), and analyze their contents. The program supports standards 802.11a/b/g/n/ac/ax and can work with most Wi-Fi adapters that support the mode RFMON (Radio Frequency Monitor).

Main functions of the program:

• 📡 Packet capture in real time with filtering by MAC addresses, SSIDs or protocol types.
• 🔍 Traffic decryption (if key available) for protocols WEP, WPA, WPA2.
• 📊 Statistics analysis: signal strength, channel load, types of devices on the network.
• 🛡️ Identifying vulnerabilities, such as weak passwords or outdated encryption protocols.

It is important to understand that CommView for WiFi by itself does not hack networksIt only provides data that can be used for analysis. For example, the program can capture WPA2 handshake (four-way handshake), but to decipher it you will need additional tools like Aircrack-ng or Hashcat — and even then, success is not guaranteed if the password is complex enough.

⚠️ Attention: Usage CommView for WiFi Intercepting traffic from other networks without the owner's permission is illegal. In Russia, this is classified as unauthorized access to computer information (Article 272 of the Russian Criminal Code), with possible penalties including imprisonment.

What data can be obtained using CommView for WiFi?

The program allows you to collect a variety of information about wireless networks in your area. Here's what you can find: legally (for example, to audit your network):

However, there is data that CommView for WiFi can't get without any additional manipulations:

• 🔑 Wi-Fi password in clear text (only the handshake hash, which needs to be decrypted separately).
• 📱 Contents of encrypted traffic (for example, messages in instant messengers or website passwords).
• 🌍 Data from networks with WPA3 (the modern protocol is resistant to most attacks).

Step-by-step instructions: how to capture a WPA2 handshake to analyze your network

If you want to test the durability own Wi-Fi password, can you legally capture a handshake? WPA2 and try to decipher it. Important: this process does not give a guaranteed result — it all depends on the complexity of the password. Here's how to do it:

Install CommView for WiFi on Windows PC

Connect a compatible Wi-Fi adapter (e.g. Alfa AWUS036ACH)

Run the program as administrator

Select your adapter from the list of devices-->

Step 1: Configuring the adapter in monitoring mode

1. Open CommView for WiFi and go to Options → Adapter.
2. Select your Wi-Fi adapter and click Properties.
3. Check the box Monitor mode (monitoring mode).
4. Click OK and wait for the adapter to switch.

Step 2: Capturing a Handshake

1. In the main program window, click Start Capture.
2. Wait until a device (such as a smartphone) appears on the network and connect it to Wi-Fi.
3. In the packet log, find the lines marked EAPOL - this is a handshake.
4. Save the capture to a file (File → Save) with extension .ncf.

Step 3: Export the handshake for analysis

1. Open the saved file in CommView for WiFi.
2. Find the handshake packets (there should be 4 of them).
3. Export them to format .cap or .hccapx for further analysis in Aircrack-ng or Hashcat.

⚠️ Attention: If your password is longer than 12 characters and includes mixed-case letters, numbers, and special characters, cracking it could take years even on powerful hardware. Modern video cards (e.g., NVIDIA RTX 4090) check about 1 million passwords per second, but this is still not enough for reliable combinations.

Why Most "Hack Instructions" Don't Work

The internet is full of guides like "How to Hack Wi-Fi in 5 Minutes Using CommView," but in practice, they're either outdated or contain critical errors. Here's why:

• 🕰️ Obsolete protocols: Most of the instructions are designed for WEP, which has not been used since the 2010s. Modern routers operate on WPA2/WPA3.
• 🔒 Complex passwords: Even if you capture a handshake, brute-forcing a password 15+ characters long with mixed case is virtually impossible.
• 🛡️ Deauthentication protection: Many routers block repeated connection attempts after several failures, which prevents handshake capture.
• 📡 Adapter limitations: Cheap Wi-Fi adapters (for example, TP-Link TL-WN722N) do not support monitoring mode on modern versions of Windows.

Moreover, router manufacturers are constantly updating firmware to patch vulnerabilities. For example, an attack KRACK (2017), which allowed to bypass encryption WPA2, was quickly fixed on most devices. Currently, it doesn't work on routers with the latest firmware.

What is a KRACK attack?

The KRACK (Key Reinstallation Attack) attack exploited a vulnerability in the protocol WPA2, allowing an attacker to intercept and decrypt traffic between a device and an access point. However, implementing this vulnerability required physical presence within the network coverage area and specialized equipment. After information about the vulnerability was published, all major vendors released patches.

Another myth is “hacking through WPS"Yes, the protocol Wi-Fi Protected Setup vulnerable to brute force (due to short PIN code), but:

• Modern routers are turned off WPS by default.
• After several unsuccessful attempts, many devices block access.
• The attack takes hours and is easily detected by the monitoring system.

How to protect your network from attacks with CommView for WiFi

Instead of trying to hack someone else's Wi-Fi, it's much more useful to use CommView for WiFi For strengthening one's own networkHere's what you can do:

• 🔐 Encryption check: Make sure your router is using WPA3 or at least WPA2-AES (Not TKIP!).
• 📶 Channel analysis: Find the least crowded channel in the 5 GHz band to reduce interference.
• 👤 Device Control: Check if there are any unknown MAC addresses on the network (possible "freeloading neighbors").
• 🛡️ Password test: Capture your network's handshake and try to decrypt it using Hashcat — If the password has been hacked within a few hours, it must be changed immediately.

Recommendations for setting up a router:

1. Turn it off WPS in the router settings (Advanced → Wireless → WPS).
2. Set a password of at least 15 characters using capital letters, numbers, and special characters.
3. Enable MAC address filtering (although this is not a panacea, it will make life more difficult for random connections).
4. Update your router firmware to the latest version (vulnerabilities are often fixed in new releases).

⚠️ Attention: If in the logs CommView for WiFi If you detect suspicious activity (for example, multiple connection attempts from the same MAC address), this could be a sign of an attack. In this case, we recommend changing your Wi-Fi password and enabling notifications for new devices on the network (if your router supports this feature).

CommView for WiFi Alternatives: Legitimate Network Analysis Tools

If CommView for WiFi If it seems too complicated or you are looking for free alternatives, take a look at these programs:

For beginners, the best choice would be Wireshark — it's free, cross-platform, and has extensive documentation. However, to capture packets, you'll also need an adapter that supports it. monitor mode.

If you use Linux (For example, Kali Linux), That Aircrack-ng Provides a complete set of tools for Wi-Fi security testing, including:

• airodump-ng — packet capture;
• aireplay-ng — deauthentication of devices for capturing handshake;
• aircrack-ng — brute force passwords.

However, we repeat: all these tools are intended exclusively for legal auditTheir use against other people's networks is punishable by law.

Legal Consequences of Unauthorized Wi-Fi Access

In Russia, hacking Wi-Fi networks is regulated by several articles of legislation:

• 📜 Article 272 of the Criminal Code of the Russian Federation ("Unauthorized access to computer information") - a fine of up to 200 thousand rubles or imprisonment for up to 2 years.
• 📜 Article 273 of the Criminal Code of the Russian Federation ("Creation, use and distribution of malicious programs") - if specialized software was used for hacking.
• 📜 Article 138 of the Criminal Code of the Russian Federation ("Violation of the privacy of correspondence") - if as a result of hacking, user traffic was intercepted.

It doesn't matter whether the network owner suffered actual losses. The mere fact of unauthorized access is a crime. In 2023, a student was arrested in Moscow for hacking into a dorm's Wi-Fi network to download movies. He faced up to two years in prison, but the case was dismissed due to reconciliation between the parties (he compensated for the damages and wrote a statement of remorse).

In other countries, the penalties can be even harsher. For example, in the US, Wi-Fi hacking is classified as felony (serious crime) under the law Computer Fraud and Abuse Act (CFAA), which carries a fine of up to $250,000 and a prison term of up to 5 years.

⚠️ Attention: Even if you "just wanted to check," but you intercepted someone else's network traffic, that's already a crime. Courts classify such actions as "unauthorized access," regardless of the motive.

FAQ: Frequently asked questions about CommView for WiFi and WiFi security

Is it possible to hack Wi-Fi with WPA3?

Protocol WPA3 It is resistant to most known attacks, including handshake interception. However, it does have vulnerabilities, such as Dragonblood (2019), which in theory allow the security level to be lowered to WPA2But exploiting these vulnerabilities requires physical access to the network and specialized equipment. In practice, hacking WPA3 unlikely.

What should I do if my neighbor hacked my Wi-Fi?

If you notice suspicious devices on your network:

1. Change your password to a more complex one (at least 15 characters).
2. Enable MAC address filtering (although this is not a panacea).
3. Update your router firmware.
4. Turn it off WPS and a guest network if it is not used.
5. Check the connection log in the router settings (DHCP Client List).

If attacks continue, you can file a police report under Article 272 of the Russian Criminal Code (evidence is required, such as logs with the attacker's MAC addresses).

Can I use CommView for WiFi on Android?

No, CommView for WiFi It's only available for Windows. For Android, there are alternatives like WiFi Analyzer or NetCut, but they don't offer such in-depth packet analysis capabilities. To fully capture traffic on Android, you'll need:

• Root access;
• Installation Termux and tools like Aircrack-ng;
• Adapter with support monitor mode (via OTG).

However, there are very few legal ways to use such tools on Android due to the limitations of the OS.

How can I check if my Wi-Fi has been hacked?

Signs that your network is compromised:

• 📉 Unexplained drop in internet speed;
• 🔌 Unknown devices in the list of connected devices (DHCP Client List in the router);
• 🔄 Frequent connection breaks;
• 💾 Unexpected increase in traffic (you can check this in your provider's personal account).

To check, use CommView for WiFi or Wiresharkto analyze traffic for suspicious packets.
