![我的新 D-Link (DWA-130) USB 适配器存在速度问题](https://linux22.com/image/1153847/%E6%88%91%E7%9A%84%E6%96%B0%20D-Link%20(DWA-130)%20USB%20%E9%80%82%E9%85%8D%E5%99%A8%E5%AD%98%E5%9C%A8%E9%80%9F%E5%BA%A6%E9%97%AE%E9%A2%98.png)
我对 Ubuntu 还很陌生,但是我尝试过一些其他人使用类似硬件版本提供的解决方案,但都无济于事。其中一些解决方案我试过了。
我现在很绝望。我错过了什么?请帮帮我!
我有一个 Windows 10 双启动,它以更高的速度运行相同的 USB 适配器,所以我知道问题不在于 WiFi 信号。(70+ Mbps 对比 Ubuntu 中的 2-3 Mbps)
我当前的 Ubuntu 版本是 16.04 LTS,我得到了 4.13.0-32-generic
。从uname -r
结果lsusb
