Check WIFI connection

I have here this other snippet for check if exist one active and connected only.

private boolean isNetworkEnabled() {
    ConnectivityManager conMgr = (ConnectivityManager) mActivity.getSystemService(
            Context.CONNECTIVITY_SERVICE);
    NetworkInfo i = conMgr.getActiveNetworkInfo();
    if (i == null || !i.isConnected() || !i.isAvailable()) {
        return false;
    }
    return true;        
}
