If you are unable to connect your Alexa Voice Control to the Internet: Turn off the power to Voice Control Alexa at the main switch, then turn it back on and restart your Internet/Wi-Fi router. If this does not resolve the issue, and if you have already manually configured your router, it is possible that the router configuration is blocking the connection to Voice Control Alexa. 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 the router, in the following format http://192.168.xx (for example http://192.168.1.1). This is indicated in the router manual. Step 2: Sometimes a username and password are requested. On most routers, this is "admin" and "admin". Otherwise, refer to your manual. Step 3: You can then access your router's configuration interface. Step 4: If you are using parental controls, check that you have authorized Alexa Voice Control. To do this, check if its MAC address (see: Where to find the MAC address of the Alexa Voice Control?) is in the list of authorized devices. Step 5: If you are using a sleep function on your router, disable it. If you still cannot reconnect, follow these steps: Step 1: First, try assigning a fixed IP address to the Alexa Voice Control by indicating its MAC address (How do I find the MAC address or serial number of my product?). If you have an Android smartphone, you can also assign a fixed IP to the smartphone. If necessary, there are tutorials to help you with this configuration: in your browser, type the brand and model of your router. Then, write "Static IP for MAC address" in your browser. Step 2: Next, you can check the Wi-Fi frequency band your router is using. Alexa Voice Control does not work with the 5 GHz frequency. Make sure that 2.4 GHz mode is enabled. Step 3: If the Wi-Fi channel has been manually changed, it may no longer provide an optimal connection. Make sure that the "automatic Wi-Fi channel selection" mode is enabled. Step 4: Finally, if your network has one or more Wi-Fi repeaters, make sure that each of these Wi-Fi access points has a different name (or SSID) and that Alexa Voice Control connects to the one with the strongest signal.
