Troubleshoot wireless interference

Wireless interference can give you trouble connecting Nest products or other wireless devices. It can also cause slow network communications or intermittent disconnections. So your Nest products might continuously disconnect and reconnect, or they may be slow to respond to app control.

Wireless interference typically comes from three sources: walls and floors blocking wireless signals, other Wi-Fi networks using the same channel as your own Wi-Fi network, and appliances and electronics emitting radio frequency interference.

Some symptoms are:

  • You have trouble connecting your Nest product to Wi-Fi during initial setup
  • Your Nest product repeatedly disconnects and reconnects to Wi-Fi.
  • Your Nest product is "Offline" in the Nest app but reconnects automatically.
  • Your Nest product responds slowly to changes you make with the Nest app.
  • There are gaps or missing data on your Nest product’s app History page.

Troubleshooting tips

  1. Some Wi-Fi routers or access points have adjustable antennas. Pointing the antenna to aim the signal at your Nest product can help improve the connection.
  2. If possible, move your Nest product or router to a new location. A few inches or a couple of feet can make a big difference in signal strength.
  3. In some homes, moving your router or access point closer to your Nest product can improve the connection.
  4. Many of the latest routers can automatically find the least crowded Wi-Fi channel. Check your router’s documentation to find out how to enable this feature.
  5. If you already have channel auto-switching enabled but are still having trouble, try manually setting the channel and testing to find the fastest one.
  6. If your router is more than a few years old, consider upgrading to a new one.
  7. Try moving other electronic devices that can cause interference--sometimes a few feet can make a big difference in wireless signal quality.
  8. Some wireless devices, like cordless phones, can broadcast and receive both 2.4 GHz and 5 GHz signals. If you suspect a particular device, it may have options to switch frequencies. If other products in your home are using a 2.4 GHz Wi-Fi connection, try switching to the 5 GHz frequency.
