# Smart Home Devices Losing Wi-Fi Connection

Smart home devices (thermostats, locks, cameras, lights) keep going offline or becoming unresponsive.

Network & Wi-Fi

### Why IoT Devices Are Different

 Most smart home devices use the **2.4 GHz band only**, have small antennas, and limited processing power. They're more sensitive to network changes than phones or laptops.

### Common Causes

1. **Too many devices on one AP** — If 30+ IoT devices are on a single access point, it can get overwhelmed.
2. **Channel congestion** — The 2.4 GHz band only has 3 non-overlapping channels (1, 6, 11). In dense neighborhoods, interference is common.
3. **DHCP exhaustion** — If your DHCP pool is too small, devices can't get an IP address.
4. **Wi-Fi password was changed** — IoT devices don't prompt you to re-enter a password. They just silently fail to connect.
5. **Router firmware update** — Some updates change settings or restart the network, and IoT devices can struggle to reconnect.

### What to Do

1. Check your router's connected device list — is the device showing up?
2. Power cycle the affected device (unplug for 30 seconds).
3. If the device has been offline for a while, you may need to re-run its setup process through the manufacturer's app.
4. Ensure your DHCP pool has enough addresses (we recommend at least 200 for smart homes).

### Smart Systems Tip

 We deploy dedicated IoT VLANs and SSIDs for smart home devices, keeping them isolated from your main network for both security and performance.
