If you are unable to connect your Alexa voice control device to the internet: Turn off your Alexa voice control device at the main power switch, then turn it back on, and also restart your internet/Wi-Fi router. If this does not resolve the issue and you have already manually configured your router, it is possible that your router configuration is blocking the connection to your Alexa voice control device. In this case, refer to your router manual and follow the instructions: Step 1: In your computer's internet browser, enter the local address of your router, in the form below http://192.168.xx (for example http://192.168.1.1). This step is outlined in your router's manual. Step 2: You may be prompted for a username and password. For most routers, this is "admin" and "admin." If not, check your manual. Step 3: You can now access the router's configuration interface. Step 4: If you're using parental controls, make sure you've permanently authorized the Alexa voice control device. To do this, check that the MAC address (See chapter: Where can I find the MAC address of my Alexa voice control device?) is in the list of authorized devices. Step 5: If you are using a router sleep function, disable it. If you still cannot reconnect, follow these steps: Step 1: First try to associate a fixed IP address with the Alexa voice control device by entering the MAC address (See chapter: How do I find the MAC address or serial number of my product?). If you have an Android smartphone, you can also associate a fixed IP with the smartphone. If necessary, there are tutorials to help you with this configuration: in your browser, enter the make and model of your router. Then type “Static IP for MAC address” in your browser. Step 2: Next, you can check the Wi-Fi frequency band used by your router. The Alexa voice control device does not work with the 5 GHz frequency. Make sure that the 2.4 GHz mode is enabled. Step 3: If the Wi-Fi channel has been changed manually, it may no longer allow an optimal connection. Check that the “Automatic Wi-Fi channel selection” mode is enabled. Step 4: Finally, if your network has one or more Wi-Fi repeaters installed, make sure that each of these Wi-Fi access points has a different name (or SSID) and that the Alexa voice control device connects to the one with the strongest signal.
