    今天在笔记本上安装了deepin，更新到了官方最新版本，发现用usb无线网卡，存在很严重的问题。
    首先我家是100兆电信宽带，其他电子设备上网完全没有发现问题，唯独这台笔记本用usb网卡的时候，网速就是不稳定，刚开始是正常的，不久就降速维持在50--100kb/s，。扎心了老铁。网速再也上不去了。

    这张是有问题的usb网卡      01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

    这张是笔记本自带的无线网卡         02:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)


    用笔记本自带的无线网卡完全没有问题。

    echo "nohwcrypt=1" > /etc/modprobe.d/rt2800usb.conf
    update-initramfs -u
    reboot

    还可以试一试把蓝牙关掉看看....

    重启之后发现并没有效果，网速还是100kb以下。
