Android 6.0.1, Samsung J3
While I'm connecting to my school's unprotected guest wifi, it would usually work just fine, but now it's saying it's failed to obtain the IP address. I've tried the airplane mode trick, forgetting the network and reconnecting, changing the device name, rebooting, and the static IP setting. When I use the static IP, it does connect, but doesn't actually have internet. When I use the Chromebook though (where I'm posting from) and connect to the same network, it works just fine. When I went home, I tried using both my phone and my Chromebook to connect to my home's wifi, and the phone didn't connect but the Chromebook did. How do I fix this?
