WifiManager myWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();
int ipAddress = myWifiInfo.getIpAddress();
System.out.println("WiFi address is " + android.text.format.Formatter.formatIpAddress(ipAddress))

What you want is DhcpInfo....

final WifiManager manager = (WifiManager) super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
final String address = Formatter.formatIpAddress(dhcp.gateway);

This will determine the formatted gateway IP address, which should be what you're looking for.
