Wireless connection keeps saying validating identity
When status is Connected, tap Advanced to view the client's assigned IP address.Once your Android Wi-Fi client has a valid IP address, use Ping to verify network connectivity.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.
Tap Settings If Wi-Fi is off, tap the slider to turn Wi-Fi on.
When Wi-Fi is on, a signal indicator appears at the top right corner of your home screen.
Most Android devices do not include a user-accessible ping app, but you can still verify network connectivity as follows.
If your Android Wi-Fi client still cannot connect, get a valid IP address or ping any other system connected to the same subnet, it's time to look for wireless-specific problems.In general, newer APs and routers are required to provide backward compatibility with older generations of Wi-Fi, but data rate settings must still match.
