为什么升级到 21.10 后我的 WiFi 连接不稳定？

为什么升级到 21.10 后我的 WiFi 连接不稳定？

我的 WiFi 连接通常很稳定、可靠。我最近从 21.04 升级到了 21.10，现在我的 WiFi 连接有时会断开。我的补救措施是转到屏幕右上角的菜单，手动关闭 WiFi，然后重新打开。电脑重新连接，一切正常……除非我不在。我正在运行 2014 年的 MacBook Air，并通过终端命令进行了内核修改，这要感谢这个论坛很久以前，我的连接在 Ubuntu 的各种更新中一直很稳定、稳定……直到现在。

这里的多个建议向我展示了如何检查日志，我也试过了，但不知道我在看什么，除了“断开连接”和“连接”之类的字眼。最近的一个贡献让我用新的固件更新了内核的某些部分，并向我展示了如何做到这一点。固件更新后，我很快就连接上了，我觉得我没事。大约 1500 左右，我又断开了连接。

除了“断开连接”之外，这些对我来说都没有任何意义。

虽然我得到了很多帮助，但问题并没有解决。我的 wifi 设备的驱动程序允许计算机“看到”该设备，但其断开连接的原因尚未解决。我尽我所能，去接受我得到的帮助。我不知道如何量化谁对我的帮助更大。我当然愿意把我的“积分”给任何合适的人，我会服从这个组织的决定。我所持有的任何东西当然都可以去到它应该去的地方，我对此很满意。谢谢大家。

答案1

您有一张 Broadcom BCM4360 卡，目前正在使用驱动程序wl。有与 Broadcom 系列相关的旧报告指出：1) 有几种可用的驱动程序（1), 2) 人们通过尝试替代驱动程序成功让 WiFi 正常工作。也许这就是你过去所做的。所以你现在可以尝试同样的做法。我会发布指南，你可能会填补空白（如果有的话）。

司机

似乎至少有几种可用的驱动程序bcma-pci-bridge：（2), wl。你可以尝试类似

$ sudo modprobe -r wl bcma
$ sudo modprobe bcm43

固件

您也可以尝试更新固件（3）。

驱动程序配置

还请注意，根据2，您的 WiFi 有两个天线。您可以尝试更换天线。您必须通过

$ modinfo wl

（或者wl使用您尝试的任何驱动程序进行更改）。

蓝牙

列出了另一种卡型号（2) 也集成了蓝牙，它经常是干扰源，但显然只有 iMac 才包含蓝牙。您可以确认这一点以排除干扰。

  2. 在 Macbook Pro 上安装 14.04 时没有无线

请发布以下信息

  1. 命令输出

    $ uname -a
$ sudo lshw -class network
$ ls -al /etc/pm/config.d/
$ ls -al /etc/modprobe.d/
$ lspci -knn | grep Net -A4
$ modinfo wl
$ sudo iwlist freq
$ sudo iwconfig
$ inxi -Fxz
$ nmcli device wifi list
$ sudo lsmod | grep wl
$ iwlist scan | egrep -i 'ssid|quality'
$ lsusb
$ usb-devices
$ cat /etc/modprobe.d/wl.conf
$ grep [[:alnum:]] /sys/module/wl/parameters/*

    您可以通过上述命令获取 wifi 驱动程序lspci -knn | grep Net -A4。

  1. 您的计算机的完整品牌/型号。
