Block IoT internet access with VLANs (Guest network method)¶

Works on most home routers—ASUS, TP-Link, Netgear, etc.

Steps:

1. Log into your router:

   • Type your router’s IP into a browser (usually 192.168.1.1 or 192.168.0.1).

   • Default login is often admin + password (check the router’s sticker).

2. Enable “Guest Network”:

   • Find Wireless Settings → Guest Network (ASUS/TP-Link) or Advanced → Guest Access (Netgear).

   • Name it “IoT Jail” (or anything memorable).

   • Check “Isolate devices” (blocks gadgets from talking to each other).

3. Block Internet Access (Optional):

   • Some routers let you restrict guest networks to local only (no web access).

   • Look for “Client Isolation” or “AP Isolation” in settings.

4. Connect IoT devices to the Guest Network:

   • Go to your smart device’s Wi-Fi settings and join “IoT Jail” instead of your main network.

Done! Now your smart bulbs/cameras can not spy on your laptop or phone.
