Are you rooted/running a custom ROM? If not, what version are you on?

have you rebooted the device to see if that helps?

If that didn't work, the next thing would be a factory reset.

Have you installed any applications on your network that work with WiFi settings or network devices ? I installed streaming media applications on my windows pc and at least one of them altered the WiFi connection to the Router - N7 could not login as before.

I had to uninstall them and reset my Router to be able to login to WiFi again after.
