Wifi 适配器(Intel Corporation Wireless 3165)频繁断开连接

我的 Wifi 适配器每 5-10 分钟就会断开一次。我了解到,这是某些用户的常见问题,特别是如果您的网卡是英特尔的。

有关我的机器的一些信息:

$ lspci|grep Network

$ uname -a

日志

dmesg这是断开连接之前的输出:

[ 1042.712511] wlp2s0: deauthenticating from 8c:0c:90:08:dd:4c by local choice (Reason: 3=DEAUTH_LEAVING)

这是重新启动适配器后的输出sudo service network-manager restart

[ 2192.019982] iwlwifi 0000:02:00.0 wlp2s0: disabling HT/VHT due to WEP/TKIP use

尝试的解决方案

许多用户建议/etc/modprobe.d/iwlwifi.conf通过添加以下行来禁用电源管理:

options iwlwifi 11n_disable=1 power_save=0 power_level=5 bt_coex_active=0` at the end of 

其他的建议删除模块acer_wmi

sudo modprobe -r acer_wmi

其他的 建议定义REGDOMAIN变量/etc/default/crda

sudo iw reg set US
sudo sed -i 's/^REG.*=$/&US/' /etc/default/crda

也可能是因为有两个实例wpa_supplicant

systemctl list-units

如果是,您可以删除其中一个:

systemctl disable NetworkManager-wait-online.service
systemctl disable net-auto-wired.service
systemctl disable net-auto-wireless.service

最后,我尝试使用 Ubuntu 19.04 从 USB 启动,但问题仍然存在,日志消息与上面的相同。

无论如何,我已经尝试了这些方法,但它们并不能解决问题,wifi适配器随机断开连接,并始终在日志中显示此消息:

[ 1042.712511] wlp2s0: deauthenticating from 8c:0c:90:08:dd:4c by local choice (Reason: 3=DEAUTH_LEAVING)
