I have problems connecting the Echo Dot 3 to Wifi, tried virtually everything , including a reset , different Bands 2.4 and 5 ghz, keeps getting to stage" Now go back to Alexa app " and it straight away after connecting to Amazon 8U it keeps reverting to the message "Your internet may be disconnected", all other devices connect fine.
Your Echo Dot requires an active Wi-Fi connection to speak, process your commands, and stream media.
Before you begin
Plug your Echo Dot into a power outlet.
Open the Alexa app.
Echo Dot connects to dual-band Wi-Fi (2.4 GHz / 5 GHz) networks that use the 802.11a / b / g / n standard. Echo Dot does not connect to ad-hoc (or peer-to-peer) networks.
In the Alexa app, open the left navigation panel and then select Settings.
Select your device and then select Update Wi-Fi. If you're adding a new device to your account, select Set up a new device instead.
On your Amazon Echo (1st Generation) device, press and hold the Action button until the light ring changes to orange. Your mobile device will then connect to your Amazon Echo (1st Generation) device. A list of available Wi-Fi networks appear in the app.
Note: The Alexa app may ask you to manually connect your device to your Amazon Echo (1st Generation) device through your Wi-Fi settings.
Select your Wi-Fi network and enter the network password (if required). If you don't see your Wi-Fi network, scroll down and select Add a Network (for hidden networks) or Rescan.
MAC address: If you need to add your Alexa device to your router's list of approved devices, scroll down on this screen until you see the MAC address.
Optional - Save your Wi-Fi password to Amazon: Any Wi-Fi passwords saved during setup automatically appear when you connect a new Alexa device to the same Wi-Fi network. The password is also remembered if you switch between saved Wi-Fi networks. For more information, go to Saving Your Wi-Fi Passwords to Amazon FAQs.
Optional - Connect to a public network: Enter any required information if you are connecting to a public network that requires a web browser to sign in, like a school or hotel. The information could be a pre-shared password, room number, or just a button to accept conditions for using the network. This information cannot be saved to Amazon. Contact the network owner for more information.
Select Connect. After your device connects to your Wi-Fi network, a confirmation message appears in the app. You're now ready to use Alexa.

It always amazes me how little I know about a lot of things !!
I have done all this exactly, and as the above instructions each and every time and also done a reset nearly 3 times. The problem is as soon as you select the Amazon xxx, it says connected and now go to the App, and just before it does, each and every time it instantly says Your Internet may be disconnected and does not go any further after we input the password to the band showing I am connected to, I have tried on both 2.4ghz and 5ghz and even tried the Guest as I have read it may work. Believe me I have tried now nearly 20 times, just not connecting. All my other 3 devices, phone TV etc connect no problem. I don't know whether the latest software has caused it. I am quite familiar with the setup as I have installed a similar one for my relative.
