I have a Dell XPS, a VIZIO and Linksys Routers. The Linksys11212 Wi-Fi is fine for my XPS and VIZIO. I went to Verizon (because it is cracked screen) and checked "something". When I got home, my phone MOTO Z3 doesn't Wi-Fi. I can't remember my password (my stroke) even though my Linksys is fine.
No need to apologize, as I thank you for sharing those helpful details. While we wouldn't have any access to your home internet to see any specific details, please check out this link to contact Lynsys Support: https://www.linksys.com/us/support/ . You can also look for the specific model of your router to get some helpful topics there, but the end result is that you would be signing into your router's admin page to view the SSID (name of your Wi-Fi) and the password. Since it's already working on your other devices, I would not recommend changing the SSID or password. As for your Moto Z3, please use this link to set up a Wi-Fi connection once you have the password: https://www.verizonwireless.com/support/knowledge-base-219030/ . Let me know if that helps with what you were looking for.
