I got a new modem last week and I cannot connect it with my Echo Dot. I've tried everything and it just won't connect. I have a wireless printer, had no problem with connecting that. I see that this is on my computer, however, when I click on it (the Echo Dot), nothing happens. So I was going to install Alexa app on my computer again but it will only let me connect to my phone. I don't want it on my phone. I found a lot of places to download the app but am not sure they are legit. I don't know what to do. Can anyone tell me what's going on and do I trust other sites to get the download from?
