How do you connect Alexa or Google Home to WiFi for the first time?
Both start in a phone app. Have your WiFi name and password ready and keep the device near the router. Menu names change by app version, so check the manufacturer’s page.
| Device | Steps | Good to know |
|---|---|---|
| Echo, Echo Dot, Echo Pop | Plug in. Alexa app, Devices, plus icon, Add Device, Amazon Echo, then follow the prompts | Update the Alexa app first |
| Google Nest or Home speaker, display | Plug in. Google Home app, Add, Device, scan the QR code or enter the setup code, wait for Connected | Phone needs Android 9 or later, or iOS 17 or later, with Bluetooth on |
| Chromecast (3rd gen or older) | Google Home app, Add, Device, follow the steps | Use a mobile device, not a computer. Try 2.4 GHz if it will not connect |
How do you change the WiFi network or password?
A new router, name or password means each speaker, display and streamer needs the new details. See how to change your WiFi password first.
| Device | Where | Steps |
|---|---|---|
| Echo without a screen | Alexa app | Devices, your device, Device Settings, Change or remove a Wi-Fi network, then join another network |
| Echo Show, Echo Spot | On the device | Settings, Device Options, Network, make sure Wi-Fi is on, pick your network |
| Google speaker or display | Google Home app | Tap and hold the tile, Settings, Device information, Wi-Fi, Forget this network, then Add, Device, Search for device |
| Chromecast with Google TV, Google TV Streamer | The TV | Settings at the top right, Wi-Fi network, the network name, Forget network, then set up again on the new network |
| Chromecast 3rd gen or older | Google Home app | Tile, Settings, Device information, Wi-Fi, Forget this network, then set up again |
Google says to reset and set up again if the forget step shows a could not communicate message. Amazon says you can change the network in the Alexa app for Amazon and Matter devices only; third-party devices use their own app.
Several devices will not join after a router change?
If a new router or mesh needs setting up, Pixl sets up WiFi from $129 before tax. Send a photo for a fixed price. Pay after the job.
What about 2.4 vs 5 GHz and WPA2 or WPA3?
| Device | Bands | Security note |
|---|---|---|
| Echo devices | 2.4 GHz and 5 GHz, 802.11a/b/g/n. Cannot join ad-hoc networks | Amazon’s help pages we read do not list WPA3 support. Use WPA2 or a WPA2/WPA3 mixed mode if a device will not join |
| Google speakers and displays | Google tells you to try both bands on a dual-band router if setup fails | Public, shared or hotspot networks may not work |
| Earlier Chromecast models | Try 2.4 GHz if there are connection issues | Set up from a mobile device |
| Nest Wifi and Google Wifi routers | 2.4 and 5 GHz; Nest Wifi Pro adds 6 GHz | WPA2 by default. WPA3 transition mode lets WPA2 and WPA3 devices join, but some legacy WPA2 devices have issues |
If your router merges both bands under one name, giving the 2.4 GHz band its own name makes setup easier. Our guide on changing your WiFi name and channel shows how, and menu names change by router firmware, so check the maker’s page.
Why do shared networks, ISP gateways and sign-in pages cause problems?
Google lists business, shared apartment, school and dorm networks and phone hotspots as ones a speaker may not join. Amazon’s developer documentation says Alexa-enabled devices cannot be configured through captive portals, which ask you to sign in on a web page. If your condo or residence uses one, ask for a standard network or use your own router. If every device fails, contact your internet provider. See guest WiFi and an IoT network to keep smart devices on their own network.
What should you try when it will not connect?
- Check the network. Confirm other devices work. If not, reboot the router. Google says to unplug it for one minute.
- Move closer. Amazon says within 30 feet (10 metres); Google says within 15 to 20 feet (4 to 6 metres) during setup.
- Check the password. It is case-sensitive. Google says it should be at least 8 characters.
- Restart the device and the app. Unplug the Echo for 30 seconds, or a Google speaker for one minute. Force-close the Google Home app and toggle your phone’s WiFi.
- Try the other band, then a phone hotspot. Both makers suggest it as a test, though Google says hotspots are not fully supported. If it connects, the problem is your router or provider.
How do you reset Alexa (Echo)?
Restart first, then reset. Amazon’s pages say a reset erases your personal information and device connections, and that you can deregister the device from your Amazon account if resetting does not help. For Google devices, see how to reset Google Home and Nest. For your router, see how to reset a router.
| Device | Restart first | Reset |
|---|---|---|
| Echo Dot (2nd to 5th gen) | Unplug for 10 seconds | Hold Action 20 seconds to keep smart home connections. Hold Volume down and Microphone off 20 seconds for a full factory reset. Light ring turns off and on, then setup mode |
| Echo devices with a screen, Echo Spot | Unplug for 15 seconds | Hold Microphones and Camera Disable/Enable and Volume Down until the Amazon logo appears, about 15 seconds. Or Settings, Device Options, About this Device, Reset to Factory Defaults |
