在星光2使用RTL8811CU无线网卡的记录
1. 硬件和软件基础条件
硬件：StarFive VisionFive 2 v1.3B
CPU: JH7110 4Cores RISCV64GC
MEM: 4GB
Disk: Sandisk Ultra 32GB Micro-SD Card
无线网卡：COMFAST CF-811AC 802.11ac无线网卡
无线网卡芯片：RTL8811CU
无线网卡USB信息：0bda:c811
Linux版本：Linux ubuntu 6.5.0-14-generic #14.1-Ubuntu SMP Fri Nov 24 06:09:26 UTC 2023 riscv64 riscv64 riscv64 GNU/Linux
Ubuntu系统版本：Ubuntu 23.10
操作系统下载来源：ubuntu-23.10-preinstalled-server-riscv64+visionfive2.img.xz
2. 安装过程
下载开源驱动。
git clone https://github.com/morrownr/8821cu-20210916
cd 8821cu-20210916
make ARCH=riscv
sudo make install
插入USB无线网卡。不出意外的话不会出意外。在ifconfig里会出现一个类似这样的网卡信息。记住它的mac地址。
ifconfig
# wlx40a5ef217bd3: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
# ether 40:a5:ef:21:7b:d3 txqueuelen 1000 (Ethernet) <--------------------------Attention this MAC address

个人认为该步骤是可选步骤。
sudo vim /etc/udev/rules.d/70-persistent-net.rules
### 添加下面的行：注意 ###
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="yo:ur:ca:rd:ma:c", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="wlan0"
# ^^^^^^^^^^^^^^^^<------------Replace with your wifi card mac
# 使新的udev规则生效
sudo udevadm control --reload-rules
重新拔插网卡。可以看到它的名字正确了。
# wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

我们使用nmcli来连接wifi。
