暂停后 WiFi 禁用

这里是 Ubuntu MATE 新手用户。

首先，我知道这是一个有据可查的问题，我尝试了来自各个网站的多种解决方案，但都不起作用。我正在运行 Ubuntu 18.04.3，每当我挂起电脑（合上盖子）时，wifi 就会被禁用。我甚至无法重新使用它sudo service network-manager restart，所以我不知道问题出在哪里。

如果您希望我向您展示有关我的计算机的更多信息，请告诉我要使用哪些命令，我​​对 Linux 不是很有经验。这是我的 uname -a 信息：

Linux plex 5.0.0-31-generic #33~18.04.1-Ubuntu SMP Tue Oct 1 10:20:39 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

答案1

禁用 WiFi 电源管理为我解决了这个问题。在文件中/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf，我将其更改为如下所示：

[connection]
wifi.powersave = 2

重新启动 NetworkManager（sudo systemctl restart NetworkManager）然后一切就绪。

答案2

未提及驱动程序，但我认为它ath10k_pci与我的类似。要验证使用：

$ sudo lshw -c network

  *-network
       description: Wireless interface
       product: QCA6174 802.11ac Wireless Network Adapter
       vendor: Qualcomm Atheros
       physical id: 0
       bus info: pci@0000:3c:00.0
       logical name: wlp60s0
       version: 32
       serial: 9c:b6:d0:10:37:f7
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=ath10k_pci driverversion=4.14.140-0414140-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1 ip=192.168.0.10 latency=0 link=yes multicast=yes wireless=IEEE 802.11
       resources: irq:137 memory:dd200000-dd3fffff

注意倒数第二行“配置”显示driver=ath10k_pci。使用此信息创建脚本：

sudo -H gedit /lib/systemd/system-sleep/ath10k-reset

使用以下几行：

#!/bin/sh

# NAME: /lib/systemd/system-sleep/ath10k-reset
# DESC: Resets  QCA6174 802.11ac WiFi after a long suspend.
# DATE: October 14. 2019.

MYNAME=$0

restart_wifi() {
    /usr/bin/logger $MYNAME 'restart_wifi BEGIN'
    /sbin/modprobe -v -r ath10k_pci
    /sbin/modprobe -v ath10k_pci
#    systemctl restart NetworkManager.service
    /usr/bin/logger 'systemctl restart NetworkManager.service (SUPPRESSED)'
    /usr/bin/logger $MYNAME 'restart_wifi END'
}

/usr/bin/logger $MYNAME 'case=[' ${1}' ]'
case "${1}/${2}" in
    hibernate|suspend|pre*)
      ;;
    resume|thaw|post*)
      restart_wifi;;
esac

保存脚本并将其标记为可执行：

sudo chmod a+x /lib/systemd/system-sleep/ath10k-reset

下次重启后，脚本将在挂起/恢复期间自动运行。
