Apple Devices aren't connecting to Home WiFi but work everywhere else

None of my Apple devices (iPhone, Macbook) are connecting to my AT&T wifi. I have a PC that connects just fine and my Apple devices can connect to other WiFi (Starbucks, work, etc.), but for some reason, they're not working with my router at home. I called AT&T and they said the problem isn't on their end: I've re-started the router, gone back to default settings, and done everything to refresh/restart on my Apple devices as well, but I can't seem to solve the mystery. Anytime I input the password on my Apple devices it reads as "invalid password" even though I know for a fact I'm putting the correct information in. Has this happened to anyone else?
