# 一、网卡驱动安装 #

参考[Kali网卡设置comfast cf-812AC（Realtek 8812BU芯片）\_banyejiu的博客-CSDN博客][Kali_comfast cf-812AC_Realtek 8812BU_banyejiu_-CSDN]

网卡驱动安装的shell命令（自己是啥网卡，就去找对应的安装程序和安装方法）

sudo apt update
    
    sudo apt install bc -y
    
    git clone https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959.git
    
    cd rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
    
    VER=$(sed -n 's/\PACKAGE_VERSION="$.*$"/\1/p' dkms.conf)
    
    sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
    
    sudo dkms add -m rtl88x2bu -v ${VER}
    
    sudo dkms build -m rtl88x2bu -v ${VER}
    
    sudo dkms install -m rtl88x2bu -v ${VER}
    
    sudo modprobe 88x2bu

注：ifconfig 查看无线网卡id——wl开头的那个就是，比如wlan0

# 二、ubuntu wifi重连代码 #

持续扫描网络状态，10秒1间隔，断开则重连网络（python代码）

import subprocess
    import time
    import os
    from time import strftime, localtime
    import traceback
    import logging
    
    
    LOG_FORMAT = "%(asctime)s - %(levelname)s - %(message)s"
    logging.basicConfig(filename='wifi.log', level=logging.DEBUG, format=LOG_FORMAT)
    
    #ssid="UESTC-WiFi-GUEST"
    ssid="UESTC-WiFi"
     
    def reconnect():
        global ssid
        # print("%s reconnecting WiFi" % strftime("%Y-%m-%d %H:%M:%S", localtime()))
        # logging.info("%s reconnecting WiFi" % strftime("%Y-%m-%d %H:%M:%S", localtime()))
        logging.info("reconnecting WiFi: %s" % ssid)
        #os.system("netsh wlan disconnect")
        #os.system("netsh wlan connect ssid=%s name=%s" % (ssid, ssid))
        try:
            os.system("sudo nmcli dev wifi connect %s"%ssid)
        except Exception as e:
            logging.error(traceback.format_exc())
    
    
    def check_wifi():
        
        subp = subprocess.Popen('ping www.baidu.com', shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
        while subp.poll() is None:
            text = str(subp.stdout.readline())
            # print(text, 'now time: ',time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
            # logging.info("%s %s %s"%(text.replace('\n',''), 'now time: ',str(time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))))
            logging.info("%s"%(text.replace('\n','')))
            if match(text):
                reconnect()
                break
            time.sleep(10)
    #    subp.close()
    
    
    def match(text):
        if text:
            if text.find('ping: unknown host') >= 0:
                return True
            else:
                return False
        else:
            return False
     
     
    if __name__ == '__main__':
        while True:
            check_wifi()
            # print('now time: ',time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
            # print('************************************************')
            # time.sleep(60)

再让它一直挂在服务器上

nohup sudo python wifi.py &

# 三、win10 wifi重连代码 #

附带win10 wifi自动重连代码（python代码）

import subprocess
    import time
    import os
    from time import strftime, localtime
    
    #ssid="UESTC-WiFi-GUEST"
    ssid="UESTC-WiFi"
    
    def reconnect():
        global ssid
        print("%s reconnecting WiFi" % strftime("%Y-%m-%d %H:%M:%S", localtime()))
        os.system("netsh wlan disconnect")
        os.system("netsh wlan connect ssid=%s name=%s" % (ssid, ssid))
    
    
    
    def check_wifi():
       
        subp = subprocess.Popen("ping baidu.com", stdout=subprocess.PIPE)
        while subp.poll() is None:
            text = str(subp.stdout.readline(), encoding='gb18030')
            print(" %s" % text)
            if match(text):
                reconnect()
                break
           
    
    
    def match(text):
        if text:
            if text.find('请求找不到主机') >= 0 or text.find('请检查该名称，然后重试') >= 0:
                return True
            else:
                return False
        else:
            return False
    
    
    if __name__ == '__main__':
        while True:
            check_wifi()
            print('now time: ',time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
            print('************************************************')
            time.sleep(60)
