所以我使用的是 Ubuntu 13.10，并且我的电脑里有这个 USB wifi 设备（TP-Link TL-WN821N V4）。
现在，当我通过终端使用互联网时，一切都很好，我可以根据需要上传和下载整个互联网。但是一旦我打开浏览器（无论是 Firefox 还是 Chromium），我就可以导航到 4 个页面，然后我的连接就会停止。我仍然可以看到我已连接，但我无法再使用互联网了。
另外，当我断开当前连接的网络时，我将无法再重新连接。
目前，这个问题只能通过重启来解决。因此，我每访问 4 个页面，就重启一次。
我还收到了一些日志和信息：

也许值得一提的是，我也曾尝试使用 Linux 的 Windows 驱动程序安装程序来安装 Windows 驱动程序，但结果很糟糕。之后我不得不重新安装 Ubuntu。
所以是的，这里可能有什么问题？我在这里使用了错误的开源驱动程序吗？你们还需要更多信息吗？我希望我从正确的位置获取了系统日志信息，从时间表来看，这似乎是网络异常发生的时间。
答案1
找到参考这个错误其中评论建议将司机列入黑名单，如下所示：
echo "blacklist ar9170usb" | sudo tee /etc/modprobe.d/blacklist-ar9170.conf
重启后，它应该可以正常工作。如果没有，请删除该/etc/modprobe.d/blacklist-ar9170.conf文件。
