My internet crashed a week or so ago, and now many of my devices are not connecting. They claim the password is incorrect. I can connect with the same password with my computer, phones, and TVs, but not Alexa or Ring devices, or Wi-fi lights. How do I fix this?
First, what model router do you have? A Panoramic gateway(modem/router combo)? Also did your network name change when the internet crashed? Last, try a factory reset by holding the WPS button down for up to 60seconds.
Also, double check and verify on the router that the 5ghz and the 2.4 ghz pwd is the same. The SSID may be the same, but I would simply retype the pwd on both to make sure there isn't a space or something that the router put in.
