If you’re asking “who is using my Wi-Fi?”, the answer is in your router’s device list, and on JioFiber you can see it in the MyJio app in about two minutes. Spot a device that isn’t yours, block it, then change the password so it can’t come back.
The tricky part is knowing what’s actually a stranger. Plenty of “unknown” devices turn out to be your own phone, TV or smart plug in disguise, and section 4 explains why that happens.
⚡ Key takeaways
- JioFiber: MyJio app > My Device > Wi-Fi Settings > Connected Devices. You can block from there. JioAirFiber users use the JioHome app.
- Airtel Xstream and other routers: log in to the router page (often 192.168.1.1) and open the device or DHCP list.
- Changing the Wi-Fi password kicks everyone off at once, including you. It’s the cleanest fix.
- Turn off WPS when you’re not using it, and give guests a separate guest network.
- Phones hide their real hardware address by default, so an “unknown” name may be a family phone.
Who Is Using My Wi-Fi? Signs to Watch For
Diwali week is when this question pops up the most. Relatives visit, the neighbour’s kids ask for “just the password”, and by the time everyone leaves, half the colony may still be on your network.
Airtel’s own guide lists three signs worth taking seriously:
- Speed drops or lag at times when your own family isn’t streaming much.
- Data usage much higher than normal, sometimes enough to cross the plan’s fair usage limit.
- Devices you don’t recognise in the router’s device list.
None of these alone proves someone is stealing your Wi-Fi. A slow connection can just as easily be a router in the wrong corner or a TV stuck on a 4K update. But if two of the three show up together, it’s time to check.
How to Check Connected Devices on JioFiber
Jio has built the device list into the MyJio app, so you don’t need to log in to the router at all. According to Jio’s help page:
- Open the MyJio app and pick your JioFiber connection.
- Go to My Device > Wi-Fi Settings.
- Tap Connected Devices. You’ll see the phones, laptops, TVs and set-top boxes on your Wi-Fi.
- Tap a device you don’t recognise and choose Block.
On JioAirFiber, Jio says the same controls are in the JioHome app. Menu labels move around between app versions, so if you don’t see “Wi-Fi Settings”, look for Settings > Device Settings > My Device instead, which is the route given on another Jio help page.
💡 Pro tip
Before you block anything, switch off Wi-Fi on every phone and laptop in the house for a minute and refresh the list. Whatever’s still connected is either a TV, a smart device, or someone who shouldn’t be there.

For Airtel Xstream Fiber, ACT, BSNL or a router you bought yourself, the device list lives on the router’s admin page. Airtel’s guide points you to a section usually named DHCP settings or Attached devices.
- Connect your phone or laptop to the Wi-Fi.
- Open a browser and type the router address. It’s printed on a sticker under the router; 192.168.1.1 and 192.168.0.1 are common.
- Log in with the admin username and password from the same sticker.
- Open the device list. It usually shows each device’s name, IP address and MAC address.
- Block or remove anything unknown from the wireless menu, then run a speed test.
| Your connection | Where to see devices | Can you block from there? |
|---|---|---|
| JioFiber | MyJio app > My Device | Yes, per Jio |
| JioAirFiber | JioHome app | Yes, per Jio |
| Airtel Xstream Fiber | Router admin page | Yes, from the router’s wireless menu |
| Own router (TP-Link, etc.) | Brand’s app or admin page | Usually yes |
If you’re still on the default admin password, change it while you’re logged in. It’s a separate password from your Wi-Fi password, and anyone on your network can try the default one.
The “Unknown Device” That Turns Out to Be Yours
⚠️ Watch out
Don’t block every device with a strange name. Modern phones join each Wi-Fi network using a made-up address instead of their real hardware address, so a family phone can show up looking unfamiliar.
Apple’s support page explains that an iPhone identifies itself to each network with a different, private Wi-Fi address. On iOS 18 and later, you can set it to Off, Fixed or Rotating; Rotating gives the phone a new address every two weeks. Android phones have a similar randomised MAC setting.
Two things follow from this. One, a device called “Android-3f2a” or with no name at all might be your mother’s phone. Two, MAC filtering, which only lets approved addresses join, gets fiddly when addresses change. Airtel’s guide also notes MAC filtering isn’t fully secure, because someone who has your password can copy an approved device’s address.
So check before you block. On an iPhone, the private address is shown under Settings > Wi-Fi > (i) next to your network. Match it to the list.
Kick Everyone Off: Change the Wi-Fi Password
Blocking one device works, but the person who had your password still has it. Airtel calls a password change the easiest and most secure fix, because it drops every device at once.
- JioFiber: MyJio app > My Device > Wi-Fi Settings, then change the password. Jio’s security tips suggest a mix of letters, numbers and special characters, with no names or birthdays.
- Airtel Xstream: change it in the Airtel Thanks app under your Xstream Fiber connection, or on the router page.
- Dual-band routers: update both the 2.4 GHz and 5 GHz networks, or the old password keeps working on one of them.
- Reconnect your own devices with the new password. The smart TV and Wi-Fi camera are the ones people forget.

Keep Them Out: 4 Settings That Stop Repeat Visitors
Once the network is clean, these settings stop the problem from coming back.
Turn off WPS
WPS lets a device join by pressing a button on the router. Jio notes that anyone with physical access to the router could use it too, and suggests turning it off in MyJio’s My Device menu when you don’t need it.
Make a guest network
Most routers let you create a separate guest network. Airtel recommends turning on its “isolation” option, so guests get internet but can’t see your laptop, printer or camera. Give relatives that password instead of your main one.
Hide the network name (optional)
Jio lets you turn off SSID visibility under Advance Setting in My Device. Devices already connected stay connected. It won’t stop a determined person, but it stops casual “free Wi-Fi?” attempts from the next flat.
Use the strongest security option
In the router’s wireless security settings, pick WPA3 if your router offers it, or WPA2 if it doesn’t. A mixed WPA2/WPA3 option is fine when older devices need to connect.

✅ Our verdict
If one unknown device shows up once, block it and move on. If you’ve given the password to more people than you can count this Diwali, change it, update both bands, and give future guests a guest network instead. That’s the setup I’d leave running all year.
It’s also worth a look at the device list every couple of months. A cheap Android TV box or camera you forgot about can be a bigger problem than a neighbour on your Wi-Fi, as our guide to checking Android TV boxes for malware explains.
Frequently Asked Questions
How can I see who is using my Wi-Fi on my phone?
On JioFiber, open MyJio > My Device > Wi-Fi Settings > Connected Devices. For other routers, open the router’s address (often 192.168.1.1) in your phone’s browser, log in, and check the device or DHCP list.
How do I block someone from my JioFiber Wi-Fi?
In the MyJio app, open the connected devices list, tap the device and choose Block. JioAirFiber users can do the same in the JioHome app, according to Jio’s help pages.
Will changing my Wi-Fi password disconnect everyone?
Yes. Every device drops off and has to reconnect with the new password, including your own. That’s why it’s the simplest way to remove someone who knows the old one.
Why does my own phone show as an unknown device?
iPhones and most Android phones use a private, randomised Wi-Fi address for each network. So the router may not show a familiar name. Check the address in your phone’s Wi-Fi settings and compare.
Is MAC filtering enough to stop Wi-Fi theft?
No. Airtel notes someone with your password can copy an approved device’s address. A strong password, WPS off and a guest network do more.
The Bottom Line
Finding out who is using your Wi-Fi takes two minutes: MyJio on JioFiber, or the router page on Airtel and others. Rule out your own devices first, block the strangers, and change the password if it’s been shared widely. Then turn off WPS and set up a guest network for the next round of visitors.
