2.驱动安装

这里以 Xubuntu16.04系统（内核：4.14）为例

bash 复制代码 
sudo ./install-driver.sh
  • 待install-driver.sh安装完后可选择N，修改如下文件，将 /etc/modprobe.d/8812au.conf前面的 #号 去掉，保存。

  • 重启设备

使用 DKSM（支持动态内核模块）安装驱动

提供另一个驱动：https://download.csdn.net/download/qq_45445740/88627350

    1. 安装依赖包
    shell 复制代码 
    sudo apt update
sudo apt install build-essential dkms
    1. 准备驱动文件 7822UAC-7811UAC.zip

    • 解压驱动文件，并切换到解压后的目录

      shell 复制代码 
      unzip 7822UAC-7811UAC.zip
cd 7811

    • 如果没有驱动文件，可以从https://github.com/aircrack-ng/rtl8812au.git下载（这里我没验证过）

      shell 复制代码 
      sudo apt install git
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
    1. 使用 DKSM（支持动态内核模块）安装驱动
    shell 复制代码 
    sudo chmod 755 *.sh
sudo ./dkms-install.sh
    1. 若需要卸载驱动
    shell 复制代码 
    sudo ./dkms-remove.sh

3.查看无线网卡信息

  • 此时可查看到插入的无线网卡信息
bash 复制代码 
ifconfig
  • 这里以 wlx08beac134a56 为例，查看可选择的信道
bash 复制代码 
iwlist wlx08beac134a56 channel
  • 查看无线网卡的详细信息
bash 复制代码 
iw list
bash 复制代码

3.通过create_ap配置5G自发AP

下载配置create_ap

  • 这里以165信道为例
powershell 复制代码 
CHANNEL=165
GATEWAY=10.0.0.1
WPA_VERSION=2
ETC_HOSTS=0
DHCP_DNS=gateway
NO_DNS=0
NO_DNSMASQ=0
HIDDEN=0
MAC_FILTER=0
MAC_FILTER_ACCEPT=/etc/hostapd/hostapd.accept
ISOLATE_CLIENTS=0
SHARE_METHOD=nat
IEEE80211N=0
IEEE80211AC=0
HT_CAPAB=[HT40+]
VHT_CAPAB=
DRIVER=nl80211
NO_VIRT=0
COUNTRY=CN
FREQ_BAND=2.4
NEW_MACADDR=
DAEMONIZE=0
NO_HAVEGED=0
WIFI_IFACE=wlx08beac134a56
INTERNET_IFACE=enp1s0
SSID=USB-IS-Test
PASSPHRASE=12345678
USE_PSK=0
  • Q：开启5G信道后，换到了别的信道，此时再切换回原来的信道，发现是
  • 5745 MHz [149] (20.0 dBm) (no IR)
  • 5765 MHz [153] (20.0 dBm) (no IR)
  • 5785 MHz [157] (20.0 dBm) (no IR)
  • 5805 MHz [161] (20.0 dBm) (no IR)
  • 5825 MHz [165] (20.0 dBm) (no IR)
  • 此时会发现无法开启5G的信道
  • A：需要先查看当前国家代码 ：iw reg get
    设置为中国：iw reg set CN
    此时 iw list 查看可以看到
  • 5745 MHz [149] (30.0 dBm)
  • 5765 MHz [153] (30.0 dBm)
  • 5785 MHz [157] (30.0 dBm)
  • 5805 MHz [161] (30.0 dBm)
  • 5825 MHz [165] (30.0 dBm)

或者直接将 create_ap.conf 中的配置项改为 COUNTRY=CN

  • 开启后可通过Cellular-Z软件查看是否真正开启了5G信道
