第一次联网
以下命令在ubuntu22.04上测试通过
1. 检查无线网卡是否被识别¶
##### 1.1 如果是USB无线网卡¶
Bash
lsusb
以下为输出
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 004: ID 048d:5702 Integrated Technology Express, Inc. ITE Device
Bus 001 Device 009: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch) 这里有WLAN，为无线网卡。 RTL8188GU为网卡驱动型号，安装驱动的话，应该安装RTL8188GU驱动，我这里使用的是 水星MW150US_V2.0无线网卡
Bus 001 Device 003: ID 05e3:0608 Genesys Logic, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
1.2 如果是PCI无线网卡¶
2. 检查网络接口¶
Bash
nmcli device status
以下为输出
DEVICE TYPE STATE CONNECTION
enp3s0 ethernet 已连接 netplan-enp3s0
lo loopback 未托管 --
或
Text Only
ip link
以下为输出
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 74:56:3c:38:a6:eb brd ff:ff:ff:ff:ff:ff
无线网卡显示wlan0或者类似名称，这里缺少驱动。
3. 安装驱动¶
安装驱动后显示如下：
这里以安装rtl8188gu驱动为例，
https://github.com/McMCCRU/rtl8188gu# ，编译安装

nmcli device status 或 ip link 显示网络信息
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 74:56:3c:38:a6:eb brd ff:ff:ff:ff:ff:ff
4: wlx005cc2403763: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000 这个就是无线网卡

Bash
sudo lshw -C network 显示网路信息
[sudo] ken 的密码：

3. 连接wifi¶
如果是图形界面，这里可以使用右上角或者设置进行wifi连接
