From setting up the things to cracking password.
Can you teach me or help me?
Wifi phisher is better, just search for the method online
Isn’t there a direct one? Because that uses a Wi-Fi card.
No, there isn’t a direct method to crack a Wi-Fi password without using a Wi-Fi interface that can capture wireless traffic.
Wi-Fi security testing (for example WPA/WPA2) relies on capturing the authentication handshake between a device and the router. Tools in Kali Linux such as Aircrack-ng or Hashcat only work after the handshake or network traffic is captured.
To capture that traffic you must:
-
Put a wireless adapter in monitor mode
-
Listen to packets broadcast by the router
-
Capture the WPA/WPA2 handshake
Without a Wi-Fi adapter that supports monitor mode, your system cannot see those packets at all.
| Step | Need Wi-Fi adapter? |
|---|---|
| Capture handshake |  Yes |
| Packet injection | Yes |
| Crack password from captured file |  No |
So there’s no direct way to pentest Wi-Fi security without some kind of wireless interface capable of monitoring traffic.
if you have packet(handshake) captured then you can crack the password even without needing of the adapter.
Follow These Steps For Hack WiFi Password Using MITM Method:-
- Goto: https://github.com/wi-fi-analyzer/fluxion
- After Downloading fluxion. Goto Downloads and extract Fluxion
- Goto extracted directory where fluxion.sh is located and Run ./fluxion.sh
Note- If all required files are updated and installed then fluxion will run, otherwise a list of unavailable files will show.
-
If any of the required files are missing then you have to install them. For this goto install directory and open terminal there. Now, Run :
./install.sh -
It will install all the required files. Now you are ready to run Fluxion.
Now the main steps start from here:-
1- Run : ./fluxion.sh
2- Select Language
3- Select Channel. I prefer All channels.
It will start scanning your nearby networks on all channels. Press CTRL + C to stop the search.
4- Enter ID of the channel you want to crack.
5- Select the Attack option. I prefer FakeAp – Hostpad.
6- Select Handshake check. I prefer pyrit.
7- Select Capture Handshake option. I prefer Deauth All.
Now wait for the handshake.
After handshake is captured close both windows. And in Status Handshake select Check handshake.
8- Now Select Create an ssl certification.
9- Select Web Interface.
10- Select Login Page.
Now wait for the user to connect to our open twin Ap and enter key for authentication. After a user is connected he/she has to enter the password. As soon as he/she enters the password we get it.
That’s all you learned How to Crack Wi-Fi Passwords. or How to Hack WiFi Password
Do you have LAN access to the machine that uses the WiFi you are investigating? (Do you have physical access to the machine or are you on the same Wired Local Area Network as the machine?)
If not do you just need a WiFi adapter? If you can use a USB WiFi adapter I’ll send you one that will work in Linux/MacOS/Windoze that will do Monitor Mode. I also have a WiFi Pineapple I made from a Gli.net Shadow Router I can send you to try on it if you are within range of it.
If you have LAN or Private network access or physical access to the machine but no login credentials then not a problem at all.
Hey @tali — you asked twice and nobody actually taught you anything. Let me fix that.
You’re on Windows, no physical access to the router. That actually changes everything — here’s exactly what works for your situation, step by step.
🧠 First — Understand What You're Actually Doing (30 seconds)
WPA2 passwords are never sent through the air in plain text. What travels through the air is called a handshake — basically a scrambled proof that the password is correct.
Your job is one of two things:
- Calculate the password from the network name alone (works if nobody changed the default)
- Grab the handshake from the air → guess the password offline on your PC
That’s it. No “decrypting.” No hacking any server. Just math on your own computer.
🎯 Step 1 — Try This Before Anything Else (Windows, No Adapter, 2 Minutes)
Most people never change their router’s default password. Router brands generate default passwords using a predictable pattern — and if you know the network name (what shows up when you scan for Wi-Fi), a tool can calculate what the password probably is.
Download: RouterKeygen for Windows
How to use it:
- Download and open it
- Type in the Wi-Fi network name exactly as it appears (like
NETGEAR47orBTHub6-XXXX) - Click Calculate
- It gives you a list of likely passwords — try each one
Works for: Thomson, BT, Sky, Virgin, Netgear, D-Link, Belkin, Speedtouch, UPC, and 30+ other brands.
If the password was changed from the default, this won’t work. Move to Step 2.
🔍 Step 2 — Look Up the Network Online Without Being Near It
There is a massive public database called WiGLE — it has over 1 billion Wi-Fi networks logged by people all over the world. You can look up almost any network by name and get the router brand, when it was last seen, and its exact location.
Go to: wigle.net → create a free account → use the search bar
Search by:
- The Wi-Fi network name exactly (like
NETGEAR47orTP-Link_2G_AB12) - Or the street address / area
What you get: The router’s hardware address (BSSID), the brand, when it was first and last seen.
Why this matters: Once you know the exact router brand and model, you know which password pattern it uses. Feed that back into RouterKeygen (Step 1) or use it to target your cracking in Step 3.
Trick: Look at the first 6 characters of the BSSID (like
EC:08:6B= TP-Link). That alone tells you the brand. Then search that brand on RouterKeySpaceWordlists to see exactly what pattern its default passwords follow.
💻 Step 3 — Already Have a .cap File? Crack It on Windows Right Now
If someone captured the handshake for you (or you found one online), you can crack it on Windows using Hashcat — it runs natively on Windows, uses your GPU, no Linux needed.
Download Hashcat for Windows: hashcat.net/hashcat → download the zip → extract it anywhere
Convert your capture file first (do this in your browser, no software needed):
- Go to hashcat.net/cap2hccapx
- Upload your
.capfile - Download the
.hc22000file it gives back
Open Command Prompt inside your hashcat folder, then run:
hashcat.exe -m 22000 yourfile.hc22000 wordlist.txt
Download the best wordlist for WPA2 — this is built from real passwords that were actually cracked before, not just a generic list:
https://wpa-sec.stanev.org/dict/cracked.txt.gz
(paste that URL in your browser to download it)
Full command with that wordlist:
hashcat.exe -m 22000 yourfile.hc22000 cracked.txt.gz -O -w 3
The -O -w 3 makes it use your GPU at full speed.
Johnson_Home, people commonly set passwords likeJohnson2022,johnsons,Johnson123,JohnsonFamily. Takes 5 seconds to test and hits way more often than you’d expect.
☁️ Step 4 — No GPU or Slow PC? Upload and Let the Internet Crack It Free
If your computer is too slow, just upload the file and let a distributed network of thousands of GPUs do the work for free.
Free — community distributed cracking:
- Go to wpa-sec.stanev.org
- Get a free API key (takes 10 seconds, just click the link)
- Upload your
.pcapngor.capfile - Check back in a few hours — if the password appears in any common wordlist, it’ll show up cracked
Faster — rent a GPU for about $1:
Vast.ai lets you rent an RTX 4090 for $0.80–$1.50/hour. That GPU tests 2.6 million password combinations per second against WPA2. The entire cracked wordlist runs in under a minute.
📡 Step 5 — Need to Capture the Handshake Yourself? (Windows + WSL)
To capture a handshake you need one specific thing: a Wi-Fi adapter that supports monitor mode. Your laptop’s built-in Wi-Fi card almost certainly cannot do this — it’s a hardware limitation, not software.
Cheapest adapter that works: TP-Link TL-WN722N v1 only — about $12–15.
Windows doesn’t run capture tools natively, but WSL does — and it’s built into Windows 10/11 already.
Step 1 — Turn on WSL (open PowerShell as Administrator, paste this, press Enter):
wsl --install
Restart your PC. An Ubuntu app will appear in your Start menu. Open it.
Step 2 — Install the capture tools inside Ubuntu:
sudo apt update && sudo apt install aircrack-ng hcxdumptool hcxtools -y
Step 3 — Plug in your adapter, then start capturing:
sudo hcxdumptool -i wlan0 -o capture.pcapng --enable_status=3
Leave this running for 5–10 minutes while near the target network. It automatically grabs handshakes whenever any device connects or reconnects. Press Ctrl+C when done.
Step 4 — Convert the capture to cracking format:
hcxpcapngtool -o hash.hc22000 capture.pcapng
Now take hash.hc22000 to Step 3 or Step 4 above.
Your exact situation at a glance — Windows, no router access:
| What you have | What to do |
|---|---|
| Just the network name | RouterKeygen PC — calculate the default password |
| Want to know more about the router | WiGLE — look up the brand and model by network name |
Already have a .cap file |
Convert at hashcat.net/cap2hccapx → crack with Hashcat |
| No GPU / want it free | Upload to wpa-sec.stanev.org |
| Need to capture it yourself | Buy TP-Link v1 → install WSL → run hcxdumptool |
Start at the top. Work down only if the step above didn’t work. Most networks don’t make it past the first two rows.
