Are buffering videos and laggy Zoom calls driving you crazy?
Your neighbors might be stealing your WiFi without you even knowing!

How to Check if Someone is Stealing Your WiFi
Method 1: Use Your Router’s App
- Open your router’s app (e.g., TP-Link Tether, Google Home, ASUS Router).
- Go to Connected Devices.
- Look for unknown devices (e.g., “Android-2b4f”, “iPhone-7d3k”).
Method 2: Check Manually (No App Needed)
- Type your router’s IP (e.g.,
192.168.1.1) in a browser. - Log in (default username/password is usually admin/admin or on the router).
- Find “Attached Devices” or “DHCP Clients List”.

7 Ways to Stop WiFi Thieves (Works in India & USA)
1. Change Your WiFi Password (Immediate Fix)
✔ Log into your router (steps above).
✔ Go to Wireless Settings > Security.
✔ Set a strong password (mix letters, numbers, symbols).
⚠ Warning: This will disconnect all devices, so reconnect your phones/laptops after.
2. Hide Your WiFi Network (SSID)
✔ In router settings, disable “Broadcast SSID”.
✔ Now, only those who manually type your WiFi name can connect.

3. Enable MAC Address Filtering
✔ Find your device MAC addresses (Settings > About Phone > Status).
✔ Add them to the router’s MAC filter list.
✔ Only these devices can connect—others get blocked automatically.
4. Use a Guest Network (For Visitors)
✔ Create a separate WiFi for guests.
✔ Set it to auto-disable after 24 hours.
5. Limit WiFi Speed Per Device
✔ In QoS (Quality of Service) settings:
- Set max speed for unknown devices (e.g., 0.5 Mbps—too slow to use).
6. Update Your Router Firmware
✔ Old routers have security holes.
✔ Check for updates in Advanced Settings.
7. Buy a Modern Router (Last Resort)
✔ Best for India: TP-Link Archer C6 (₹2,499)
✔ Best for USA: Netgear Nighthawk R6700 ($99)
