Can you share the logcat, I suspect there might be some other issue.Try this code (as is) in a sample application to check only if Wi-Fi IP address is working

WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();

int ipAddress = wifiInfo.getIpAddress();

String ip = null;

ip = String.format("%d.%d.%d.%d",
(ipAddress & 0xff),
(ipAddress >> 8 & 0xff),
(ipAddress >> 16 & 0xff),
(ipAddress >> 24 & 0xff))
