在 Ubuntu 18.10 (DELL Inspiron) 上找不到英特尔无线 3165 WIFI 适配器

我最近从 ubuntu 16.10 升级到 18.10 LTS，但自从升级后，我有些无法连接到无线 Wi-Fi，除非我使用 USB。我尝试了几种方法都无济于事。我尝试过的一些事情包括：

sudo lshw -C network

输出：

~$ sudo lshw -C network

我确实运行了这个

lspci -knn | grep Net -A3

输出是：

~$ lspci -knn | grep Net -A3
02:00.0 Network controller [0280]: Intel Corporation Wireless 3165 [8086:3165] (rev 79)
    Subsystem: Intel Corporation Wireless 3165 [8086:4410]
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

我什至试过：

lspci -vvnn | grep Network

输出：

02:00.0 Network controller [0280]: Intel Corporation Wireless 3165 [8086:3165] (rev 79)

然后我检查它是否被阻止

rfkill list all

结果是

0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

当我跑

uname -r

我想也许 mit 是一个过时的版本，所以我按照教程升级到 5.1 现在它在我运行时看起来像这样 uname -r

5.1.0-050100rc2-generic

如果我启用安全启动，它不会启动，但会显示分配的签名错误。然后通过复制 iwlwifi-7265-13 文件 ucode 文件来更新我的 /lib/firmare，但我的 wifi 仍然无法正常工作。请帮助我真的需要让我的无线 wifi 工作。

更新：@heynnema 当我跑步时 grep -i iwlwifi /var/log/syslog*

我明白了：

更新 2：@heynnema 下面是我得到的输出

cat /etc/network/interfaces</code>

输出：

# interfaces(5) file used by ifup(8) and ifdown(8)
auto wlp2s0
iface wlp2s0 inet dhcp

至于

cat /etc/netplan/*.yaml

输出

cat: '/etc/netplan/*.yaml': No such file or directory

并为

resolvectl

结果是：

也试过

 sudo ifconfig wlp2s0 up

和

sudo ip link set wlp2s0 up

问题仍然存在

更新3：至于

dpkg -l *netplan*

我有

回答您的问题：这不是全新安装，而是升级，我遇到了一些错误，因为它在升级过程中断电了。我修复了一些方法，但从那时起无线就无法正常工作了。但是我现在工作所需的一切似乎都运行良好（希望没有出现任何问题）。

更新#4：

我确实安装了 .yaml 文件。

当我现在跑步时

cat /etc/netplan/*.yaml

我得到文件：

network:
  version: 2
  renderer: NetworkManager

更新 #5：

创建 .yaml 文件后

我做到了：

sudo netplan --debug generate

收到

DEBUG:command generate: running ['/lib/netplan/generate']
** (generate:5991): DEBUG: 17:13:02.875: Processing input file /etc/netplan/config.yaml..
** (generate:5991): DEBUG: 17:13:02.876: starting new processing pass

(generate:5991): GLib-DEBUG: 17:13:02.876: posix_spawn avoided (fd close requested)

至于：

sudo netplan apply

成功了

现在重新启动
