You can add a Wi-Fi network again by navigating to Settings and then to "Add new Wi-Fi network". Here it is indicated that you have to put the charging dock in Bluetooth mode (blue lights). If you can already see the blue lights, you do not need to do this and you can already press next. Then you can select the network you want to connect to and enter the Wi-Fi password. When this has succeeded, you will see the green lights on the charging dock and you can use Speaksee again.
