我的新 D-Link (DWA-130) USB 适配器存在速度问题

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。

  1. 在 Ubuntu 14.04.4 下安装 DWA-131 WiFi 加密狗驱动程序

  2. D-Link DWA-130 rev E1 RTL8191SU 无法连接到网络（14.04）

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是：

Bus 002 Device 004: ID 8087:0aa7 Intel Corp. 
Bus 002 Device 003: ID 0bda:0153 Realtek Semiconductor Corp. Mass Storage Device
Bus 002 Device 002: ID 0438:7900 Advanced Micro Devices, Inc.

Bus 003 Device 003: ID 2001:3c25 D-Link Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

我的结果lsmod | grep ^rt是：

rt2800usb              28672  0
rt2x00usb              20480  1 rt2800usb
rt2800lib             110592  1 rt2800usb
rt2x00lib              53248  3 rt2800lib,rt2800usb,rt2x00usb

我的结果来自sudo lshw -class network
