SOLVED! OK I figured it out! I found the "password" (aka security code) I found this link from Windows that guided me through the steps to uncover the location of the code. https://support.microsoft.com/en-us/help/4023501/windows-find-wireless-network-password
I am now able to have the Amazon Alexa Echo Dot 3rd Gen working!OK I am new here and just got an Echo Dot with my Insignia 50 Inch TV from Amazon.com. I am trying to get the DOT set up but I think I discovered what may be the problem. But 1st I will try to explain it this way -- I have a WIFI Cable Router (provided and serviced by a local internet service) It is an ARRIS Model #DG2470A. In attempting to set up the Echo DOT via the setup program using my laptop, I seem to be unable to complete the setup because when asked for a "password" for the Router, nothing I have tried seems to allow the set=up program to continue.
The setup asks me to connect to the Amazon WIFI through my WIFI settings on the laptop, so I do that --- only to see my WIFI internet connection for the laptop become "disconnected". The set-up program then asks for an Internet Connection (from the WIFI router) and as it happens it asks for that "password" (which I am unable to provide).
Now -- I THINK I know what I should try is this ---- And tell me if I am right? I think I need to have the "laptop" connected via an Ethernet cable directly to the Router. That way I am "hard-wired" to the Router with the laptop, then I can proceed to connect the Echo DOT (by finishing the set-up) to select the Amazon WIFI connection -- Does that sound right?
Once I have the Echo linked to the WIFI/Router I can then remove the hard-wired Ethernet cable to my laptop and I should be all set?
Let me know if I am mistaken here! Thanks! RichardinKY
