我已经从反向移植为我的英特尔 wifi 卡安装了 iwlwifi 驱动程序，这里是以下输出lspci -nnk | grep 0280 -A3：
00:14.3 Network controller [0280]: Intel Corporation Device [8086:a370] (rev 10)
Subsystem: Intel Corporation Device [8086:0034]
Kernel modules: iwlwifi
以下是安装 iwlwifi 驱动程序的所有步骤
apt install -t stretch-backports linux-image-amd64 linux-headers-amd64
apt-get install build-essential linux-headers-$(uname -r)
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
cd /lib/firmware
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-9000-pu-b0-jf-b0-38.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-9260-th-b0-jf-b0-38.ucode
reboot
wifi 接口在ip a我启动并运行后iwlist wlp0s20f3 scan可见，它能够很好地进行扫描，但工具栏中的 wifi 图标即使在sudo service network-manager restart.这种行为的原因可能是什么？
