我购买了华硕 AC51 USB 适配器来改善笔记本电脑 WiFi 的范围和速度（板载 WiFi 性能不佳）。在 Win10 下一切正常，但在内核为 的 Ubuntu 16.10 下我无法正确配置它4.8.0-26-generic。
当我插入加密狗时，我得到了这个dmesg：

我已经安装了联发科 7610 内核模块：
$ lsmod | grep mt7610u_sta
mt7610u_sta 892928 0
cfg80211 581632 4 iwlwifi,mac80211,mt7610u_sta,iwldvm
iwconfig向我展示了附加界面ra0，但ifconfig没有显示它。
您知道如何修复这个问题吗？
