An IP address only shows the country and the network provider, not your street or city: providers route traffic through hub cities. "Show my location" uses your device's GPS or nearby WiFi, asks your permission first, and is shown only to you.
Read my WiFi details from my computer (Windows, Mac, Linux)
Websites can't see your WiFi name or security, but your computer can show them. Run one command, paste the result here, and question 1 is answered for you. Nothing is uploaded.

- Tap your network in WiFi settings to see its security, then answer question 1.
1Which security does your WiFi use?
How to check
In the router's settings open Wireless (or WLAN) → Security. On Android, tap the network in WiFi settings; on iPhone, a “Weak security” note means WEP, WPA or TKIP.
2What is your WiFi password like?
How to check
Think about the password you type on a new phone, not the router's admin password.
3Have you changed the router's admin password?
How to check
This is the password for the settings page (often at 192.168.1.1, 192.168.0.1 or 192.168.29.1 for JioFiber). The default is usually on the sticker.
4Is WPS turned on?
How to check
WPS is the push-button or 8-digit PIN pairing. Look under Wireless → WPS.
5Can the router's settings be opened from the internet?
How to check
Called remote management, remote access or WAN access, usually under Administration or Security.
6Is UPnP turned on?
How to check
Usually under Advanced, NAT or Forwarding settings.
7When was the router's firmware last updated?
How to check
Shown under System, Maintenance or Firmware upgrade. ISP routers often update automatically.
8Do visitors and smart devices use a separate guest network?
How to check
Smart devices include CCTV cameras, TVs, smart plugs and speakers.
9Does your WiFi name reveal who you are?
How to check
For example, a family name or flat number.
1Did you confirm the exact network name with staff?
How to check
Fake hotspots copy real names, such as “Airport_Free_WiFi”.
2Does the network need a password?
How to check
A padlock next to the name in your WiFi list means it's encrypted.
3What did the login page ask for?
How to check
Many hotspots show a sign-in page before you get internet.
4Is your laptop set to “Public network”?
How to check
Windows: Settings → Network & internet → WiFi → the network → Network profile type. Mac: turn off File Sharing.
5Is auto-join turned off for open networks?
How to check
Phones rejoin networks by name, so a fake hotspot with the same name connects you automatically.
6Are you using a VPN for work or sensitive tasks?
How to check
HTTPS already encrypts most websites and banking apps.

How this WiFi security test works
Your connection, looked up honestly
Our server sees your public IP and reads who owns that IP block from public internet registry records. Your WiFi name and security stay private from websites, so we ask, or read them from your computer's own output.
A grade built from real risks
Each answer loses points by how easily it can be abused: an open or WEP network fails outright, while a revealing network name costs almost nothing.
Fixes in order of impact
The "Fix first" list puts the change that removes the most risk at the top, with the menu name to look for in your router's settings.
Check it yourself. Open your browser's developer tools (F12) and choose the Network tab. You'll see one request to our site that returns your connection details. Answering questions and reading pasted WiFi details make no requests: the grade is calculated on your device.
WiFi problems this test helps with
Find the situation you're in. Each answer points to the setting that matters.
| Your situation | What to check | Action |
|---|---|---|
| Home WiFi | ||
| I think neighbours are using my WiFi | Password strength and WPS. Change the password, turn WPS off, then check Connected devices in the router app. | |
| My ISP (Jio, Airtel, BSNL) installed the router. Is it safe as it is? | The admin password and WiFi password are often still the ones on the sticker. Change both. | |
| Which company provides my internet, and what's my IP? | Your connection at the top shows the provider, public IP, network number and whether traffic goes through a VPN. | |
| CCTV cameras, TVs and smart plugs share my WiFi | Use the guest network for them, so a hacked device can't reach your phones and laptops. | |
| My router is more than five years old | Firmware updates. Unsupported routers keep known security holes forever. | |
| Public WiFi | ||
| I'm about to use café, hotel or airport WiFi | The exact network name and what the sign-in page asks for. Fake hotspots are the biggest risk. | |
| The WiFi sign-in page asks for card or UPI details | Close it. Free WiFi never needs payment details, and this is a common phishing trick. | |
How the grade is calculated
Your WiFi starts at 100 points. Each answer takes off points based on how easily that setting can be abused by someone nearby or on the internet. "I don't know" costs a little, because an unchecked setting may be the risky one.
Grades are A for 90 and above, B for 75 to 89, C for 60 to 74, D for 40 to 59, and F below 40. An open or WEP network is graded F whatever else you answer, because anyone nearby can get in.
The public WiFi check works the same way, but rates the risk of the network you're on right now as Low, Medium or High.

WiFi security myths that leave networks open
These feel like protection but stop almost no one.
Hidden networks are easy to find, and your phone keeps announcing the hidden name everywhere you go.
Device addresses can be copied in seconds. A strong WPA2 or WPA3 password does the real work.
WPA2 is only as strong as its password. A phone number can be guessed from a single captured login.
Make a strong passwordEveryone in the café has that password. Rely on HTTPS and your device's firewall, not the WiFi password.
Habits that keep your WiFi safe
At home
- Check the connected devices list every few months.
- Change the WiFi password when a tenant, helper or technician no longer needs it.
- Keep smart devices on the guest network.
- Rerun this test after your ISP replaces or resets the router.
- Replace routers that no longer get firmware updates.
On public WiFi
- Ask staff for the exact network name.
- Use official apps and HTTPS sites for anything personal.
- Never enter card or UPI details on a WiFi sign-in page.
- Set laptops to "Public network" and turn off file sharing.
- Forget the network when you leave.
Frequently asked questions
Short answers about WPA2, public WiFi, hidden networks and privacy.
Can a website check my WiFi's encryption or password?
No. Browsers don't let any website read your WiFi name, security type, password or router settings. Tools that show a WiFi "score" without asking you are guessing. This test asks a few quick questions, or reads the security type from a command you run on your own computer.
How does the tool know my internet provider?
Every public IP belongs to a block registered to one network, such as Reliance Jio, Bharti Airtel or BSNL. Our server looks up the owner of your IP's block in public registry records. It shows the provider of the connection you're on right now, which is the hotspot's provider on public WiFi.
Why doesn't the location show my city?
An IP address is registered to a provider and a country, not a street. Providers route many customers through hub cities, so IP-based city guesses are often wrong. The Show my location button uses your device's GPS or nearby WiFi instead, only after you allow it.
Is WPA2 still safe?
Yes, WPA2 with AES encryption and a strong password is still safe for home use. WPA3 is better where all your devices support it. WEP, WPA and WPA2-TKIP are outdated and should be replaced.
Is it safe to use public WiFi for banking?
Usually, if you use the bank's official app or a site with HTTPS, because that traffic is encrypted end to end. The real risks are fake hotspots and login pages that ask for card or UPI details. Never enter those on a WiFi sign-in page.
Does hiding my WiFi name make it more secure?
No. Hidden networks are still easy to find with free apps, and your phone keeps calling out the hidden name wherever you go. A strong password and WPA2 or WPA3 matter far more.
How do I see which devices are using my WiFi?
Open the router's settings page or your ISP's app (for example the JioHome or Airtel Thanks app) and look for Connected devices or DHCP clients. Unknown devices? Change the WiFi password and turn off WPS.
Do you store my answers?
No. Your answers and anything you paste stay in your browser. Only the connection lookup contacts our server, which keeps a scrambled copy of your IP for up to 12 hours to avoid repeat lookups.
Should I always use a VPN on public WiFi?
It helps, but it isn't essential for HTTPS websites and banking apps, which are already encrypted. Use a trusted VPN for work systems and apps you're unsure about, and avoid free VPNs that sell your data.
