Broadcom BCM4360 - 5Ghz 未连接,但找到 AP

我为使我的 Broadcom BCM4360 能够看到我的 5Ghz 信道而遇到了很多麻烦(包括重新安装驱动程序)。现在,我可以看到所有仅在低信道(我猜是 <100)上工作的 5Ghz wifi 网络。但是,我无法连接到 5Ghz wifi 网络 - 即使它启动了身份验证,完成了身份验证,然后 - 没有连接。此外,连接到 2.4 GHz 网络很麻烦,因为我在这里的互联网连接速度非常低 - 速度测试中的最大速度约为 3-5 mbps,有时甚至不到 1 mbps。我尝试了以下步骤:

  • 重新安装驱动程序
  • 安装 wicd(安装后比网络管理器慢)
  • 阻止 IPv6(有点,我用过这个):

    sudo vim /etc/gai.conf

并且取消注释:

precedence ::ffff:0:0/96  100

iwlist 输出:

我的ifconfig:

我能做些什么吗?我也查找了 dmesg,但输出显示我的 wlp3s0 卡处于 IPv6 状态:

[  797.133189] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready
[  797.290173] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready

[  837.013071] IPv6: ADDRCONF(NETDEV_CHANGE): wlp3s0: link becomes ready

请注意,我还有内置网卡 wlp2s0,它在 dmesg 中显示如下:

[  980.012074] wlp2s0: deauthenticating from 04:92:26:3a:93:f8 by local choice (Reason: 3=DEAUTH_LEAVING)

我的 arch 是 x64,内核是 4.15.0-47-generic,我正在使用 Xubuntu

Description:    Ubuntu 18.04.1 LTS
Release:    18.04

更新:我已经从有关 broadcom 的其他主题中提供的驱动程序表中安装了正确的驱动程序

更新2:添加命令输出:

 lspci -knn | grep -A4 -i "Network controller"
