可以仿冒mac地址连接到wifi.
1.首先使用cdlinux扫描ssid,抓握手包--当捕获某个连接该wifi的client的时候，记下该client的mac地址。
2.用eswa解码抓包文件，获取ssid的密钥
3.用该密钥连接wifi,如果登陆不上，很可能就是该wifi设置了mac地址绑定。
4.修改你的无线网卡的mac地址为步骤1记录的client的mac地址。
4.1 安装旧版驱动。如果你的网卡是intel的，多半需要回退到12。0版本以前的驱动。
intel自12.0版本起禁止了修改mac地址。安装旧版驱动需要禁止windows 7自动安装驱动，可以用组策略设置：
o disable it go to Start and type gpedit.msc in the Start Search and press Enter. Once Local Group Policy Editor is open navigate to,
Now from the right sidebar open the key named “Turn Off Windows Update Device Driver Search Prompt” and select Enabled and click OK.
Now Restart your computer or Log Off and then sign back in. That’s it. Now Windows bother you any more. Enjoy!
Note: This will not disable the Windows Update, it will only stop prompting you to update the device driver using Windows Update. You will still be able to update the driver by manually going to Windows Update.
4.1.1 如果4.1还没法解决禁止自动安装驱动的问题，可以这样做：
- Go to Start–>Search type in gpedit.msc
- Click the file to open the Local Group Policy Editor and show Windows who is in control!!
- You want to go here: Computer Configuration->Administrative Templates->System->Device Installation. Click on the subfolder Device Installation on the left and on the right side you will see the possible restrictions.
- Right Click on Prevent Installation of Devices not described by other policy settings and edit this option, set it on ENABLED.
Reboot Windows and enjoy its inability to pollute your system with its standard driver, open gpedit.msc again and revert the change so you will be able to install your driver.
4.2修改mac工具k-mac,smac
4.3修改成功后就可以连接到wifi了
