（1）

    QString ssid = "ssid";
    QString password = "Password";

    QProcess process;

    QString cmd_password = QString("netsh wlan set profileparameter name=%1 keyMaterial=%2").arg(ssid).arg(password);
    QString cmd_connect = QString("netsh wlan connect name=%1 ssid=%2").arg(ssid).arg(ssid);
    QString cmd = "netsh wlan connect ssid=\"" + ssid + "\" name=\"" + ssid + "\" keyMaterial=\"" + password + "\"";
    bool blink = false;
    process.start(cmd_password);
    blink = process.waitForFinished();

    qDebug() << "\blink0:"<

这一部分是使用命令连接对应的WIFI ，cmd_password 是设置的密码，cmd_connect应是连接相应的WIFI，此处是使用代码连接WIFI 若手动连接 可以将这部分注释掉

（2）

QThread::msleep(1000);

经过调试发现 若为代码连接WIFI 此处需要加上1秒的延时 若为手动连接WIFI 可注释掉

（3）

    tcpSocket->connectToHost(ip, port);

    if (tcpSocket->waitForConnected(2000)) {
        connect(tcpSocket, &QTcpSocket::readyRead, this,&WIFIRecvThread::run);
        qDebug() << "Connected!";
        bLink = true;
    } else {
        bLink = false;
        QMessageBox::warning(0,"warning","Socket operation timed out!");
        return false;
    }
    return true;

此处进行连接 等待超时时间2秒
