It says I have full signal strength and am connected to wifi when I'm at school, but if I go to actually use the internet it just hangs. Old S3 worked fine.
Forgetting and retrying does nothing to help.
I tried changing the Gateway IP and DNS, and then it gave me an error message that the internet wasn't working.
What else can I try?
This is a big problem because the school is a cell service black hole, all the buildings block signal.
