If you are unable to connect your Alexa Voice Interface to the Internet: Turn off the Alexa Voice Interface at the main power switch, then turn it back on and restart your Internet/Wi-Fi router. If this does not resolve the issue and you have already configured your router manually, it is possible that your router configuration is blocking the connection to the Alexa Voice Interface. 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 following format http://192.168.xx (for example http://192.168.1.1). This is listed in your router manual. Step 2: You may be prompted for a username and password. For most routers, this is & amp; quot; admin & amp; quot; and & amp; quot; admin & amp; quot;.

Step 5: If you are using the sleep function of 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 interface by specifying its MAC address (How to find the MAC address or serial number of the product).

Step 3: If the Wi-Fi channel has been changed manually, it may no longer provide an optimal connection. Make sure that the "automatic Wi-Fi channel selection" mode is enabled. Step 4: If your network is equipped with one or more Wi-Fi repeaters, make sure that each of these Wi-Fi access points has a different name (or SSID) and that the Alexa voice interface connects to the one with the strongest signal.
