问题只出现在距离路由器两面墙的房间,并且仅配有 HP 显示器。当显示器通过 HDMI 连接到笔记本电脑时,它会开始通过 WiFi 丢失数据包。重新启动笔记本电脑、连接/断开显示器和充电的不同组合会产生相同的结果。
其他 MSI 显示器和笔记本电脑在这个房间里运行良好。HP 显示器和笔记本电脑在其他房间里运行良好。智能手机和 Windows 笔记本电脑运行良好。
设备:
Dell Vostro 3500 (P83F) (Ubuntu 20.04) HP E243 显示器
lspci |grep -E "VGA|3D"
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
01:00.0 3D controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q] (rev a1)
经过互联网上的研究,我找到了一个命令dmesg -w
,将显示器连接到笔记本电脑后,我得到了这个:

除此之外我还有其他红色原木:

我尝试使用命令更新驱动程序sudo ubuntu-drivers autoinstall
,但情况并没有改变。
我对电一无所知,这也可能是电源插座电压的问题。我想尽快验证一下这个想法。
也许有人知道是什么导致了这种行为。
编辑:
经过几次 Ubuntu 更新后,错误iwlwifi 0000:00:14.3: Queue 11 is active on fifo 1 and stuck for 10000 ms. SW [149, 188] HW [149, 188] FH TRB=0x0c010b0a4
消失了。
但是 PCI 错误依赖于改变输入端口。
