Wireless network keeps validating identity
You can change the password (or any other security parameter) associated with a saved network by tapping the network's name.
However, it is often easier just to click Forget for any misconfigured network and start fresh. WPA-Enterprise and WPA2-Enterprise log the Android Wi-Fi client into the network and deliver encryption keys using an 802.1X-capable RADIUS server.
If a compatible wireless client and AP/router can "hear" each other but still cannot connect or exchange traffic, look for a security mismatch.Once your Android Wi-Fi client has a valid IP address, use Ping to verify network connectivity.Most Android devices do not include a user-accessible ping app, but you can still verify network connectivity as follows.UMHS-8021x now authenticates using security certificates provided by Air Watch after it's enrolled.
Start by verifying that a wireless access point (AP) or router is nearby and actively offering Wi-Fi service.Note that whenever you're trying to connect an Android Wi-Fi client to any network name, status is displayed on the Wi-Fi Settings panel, in the row labeled Wi-Fi.
