win10下安装ubuntu16.04

进入 Windows 10 检查并回报无线网卡型号。可进入设备管理器无线网卡属性页面，检查"详细信息" - "硬件Id"/"位置信息" 截图贴上来。
贴图方法：图片上传到 http://www.tietuku.com/ 再把链接贴过来

谢谢！

[vickycq]

您拍的图片不太清楚，经过仔细辨认，倒数第四行应该是无线网卡。即 "Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device b822" （看不清，文字是猜的）。因此猜测，这个网卡的 PCI ID 应该是 10ec:b822。在目前最新的 Linux 内核中找不到这个 PCI ID 的任何信息，因此您可能需要耐心地等待一段时间，直到这张新网卡的支持被添加到 Linux 内核

我买个无线网卡免驱动版是不是就可以上网了呢？

如果您购买一支驱动支持较好的 USB 无线网卡，可以少折腾

[whylop]

买了一个即插即用的，发现也不好使
