Killer Wi-Fi 6 AX1650i WiFi 在 5.11 内核上连接速度慢

Killer Wi-Fi 6 AX1650i WiFi 在 5.11 内核上连接速度慢

似乎是一个非常常见且令人沮丧的话题……但我的 wifi 速度非常慢。我的速度比拨号调制解调器还慢,当你尝试开发网站时,这会让你抓狂。

临时解决方案 尝试了以下所有解决方案后,都无济于事。因此,我使用 Timeshift 将我的机器回滚到 10 月 22 日,然后我没有进行任何更新或升级……现在 wifi 似乎运行良好。因此,我计划在下个月忽略更新和升级,看看问题是否在其他地方得到解决。肯定是最近的更新导致了这个问题。

这是我的硬件:

$sudo lshw -class network -short && nmcli device status

/0/100/14.3          wlp0s20f3       network        Killer Wi-Fi 6 AX1650i 160MHz Wireless Network Adapter

我当前的内核是:5.11.0-38-generic

更多细节
$ lsb_release-a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.3 LTS
Release:    20.04
Codename:   focal

我已经尝试了这里找到的所有解决方案: Ubuntu 20.04 网络性能极慢 但什么也没起作用。

有人有什么新技巧可以让我试试吗?即使下载 1MB 也是上天的恩赐。

尽管客户端的带宽和传输量看起来很高...但这并不是我大多数时候所经历的情况...我仍然很幸运地突破了 800KB 的传输量。

更清楚的是,有些时候 wifi 可以正常工作,我可以使用 3 甚至 4 MB 的传输速率……但这种短暂的……可能会持续 30 分钟或一个小时,然后立即随机降至 50KB/s。此外,它在启动时总是很慢。

一位同事最近在戴尔笔记本电脑上遇到了这个问题,我们将其归结为无线接口的 TCP 分段卸载问题。通过禁用它ethtool解决了这个问题。

操作如下:

  1. 打开终端(如果尚未打开)
  2. 安装ethtool(如果尚未安装):
    sudo apt install ethtool
    
  3. 禁用 TCP 分段卸载:
    sudo ethtool -K wlp0s20f3 tso off
    
    笔记:设备名称wlp0s20f3是从您的问题中复制而来的。如果系统上的名称发生变化,请务必更改它。
  4. iperf3通过或您选择的其他工具 测试您的传输速度:
    [ ID] Interval           Transfer     Bitrate         Retr
    [  5]   0.00-10.00  sec   627 MBytes   511 Mbits/sec    0             sender
    [  5]   0.00-10.00  sec   628 MBytes   510 Mbits/sec                  receiver
    

如果此方法有效并且您希望使此设置永久生效,您可以设置一条udev规则以在启动时禁用 TCP 分段卸载:

  1. 创建.rules文件:
    sudo vi /etc/udev/rules.d/95-no-tso.rules
    
    笔记:请随意使用您选择的文本编辑器。
  2. ethtool针对所有无线设备 运行命令:
    ACTION=="add", SUBSYSTEM=="net", NAME=="wlp*", RUN+="/usr/bin/ethtool -K $name tso off"
    
  3. 保存文件并继续工作

这不是一个完美的解决方案,但它已经很好地解决了问题并使其成为一个可以接受的解决方案。

答案2

英特尔 Killer Wi-Fi 6 AX1650具有集成蓝牙。因此,您可能会受到广泛报道的 WiFi 和蓝牙之间的干扰(例如,1234)。您可以采取多种措施来测试此问题,然后如果发现这是问题所在,则可以修复它。您似乎对 Ubuntu 有一定的了解,并且有高于平均水平的解决问题的动力,这很有帮助。

可以尝试的事情

发布最终的行为/输出。

您有驱动程序iwlwifi。因此请尝试:

  1. 使用驱动程序选项(parms):。sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=N power_save=0 power_level=5"如果不起作用,您可以添加11n_disable=1、、disable_11ac=1disable_11ax=1重新启动。
  2. 禁用蓝牙。您可以通过 CLI 执行此操作systemctl stop bluetooth,也可以通过 GUI执行此操作设置->蓝牙-> 移动右上角的滑块,或者通过 BIOS 配置。重新启动。
  3. 禁用路由器中的 5GHz 频段。
