我对 Linux 操作系统完全陌生,昨天才安装了 ubuntu。到目前为止,我遇到了 wifi 问题,我会尝试解释问题所在。首先,这是有关我的 wlan 卡的信息:
*-network
description: Wireless interface
product: BCM43142 802.11b/g/n
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:03:00.0
logical name: wlan0
version: 01
serial: 30:10:b3:46:31:cf
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=wl0 driverversion=6.30.223.248 (r487574) ip=192.168.1.65 latency=0 multicast=yes wireless=IEEE 802.11abg
resources: irq:19 memory:f7800000-f7807fff
到目前为止,我使用安装了驱动程序sudo apt-get install bcmwl-kernel-source
,还关闭了 wlan 的电源管理,现在使用iwconfig
命令时显示为 OFF。我还尝试禁用 ipv6。但有趣的事实是,我不知道是不是真的这样,当我来到我的路由器时,wifi 没有断开连接,但当我去我的房间时,我得到 2-3 格信号它开始断开连接...我不知道,也许只是巧合...在 Windows 10 上,wifi 信号和断开连接都没有问题...也许是某种触发因素导致连接较差,它开始断开连接?
输出rfkill list all
