我已经在 18.04 下使用 XPS 13 9360 很长一段时间了，但几天前，Ubuntu 不再检测我的无线适配器。我尝试在谷歌上搜索解决方案，但都不起作用。我将内核更新到 5 希望可以修复它，但它仍然很卡。

[ 206.020459] ath10k_core: Unknown symbol ieee80211_bss_get_ie (err -2)
########## wireless info END ############
每次运行sudo modprobe ath10k_pci它都会输出：
modprobe: ERROR: could not insert 'ath10k_pci': Unknown symbol in module, or unknown parameter (see dmesg)
伴随的dmesg输出是：
[ 1675.516951] ath10k_core: Unknown symbol cfg80211_find_ie_match (err -2)
[ 1675.517491] ath10k_core: Unknown symbol ieee80211_bss_get_ie (err -2)

我也尝试过运行sudo modprobe cfg80211_find_ie_match，它给出输出：
modprobe: FATAL: Module cfg80211_find_ie_match not found in directory /lib/modules/5.0.0-32-generic
有谁知道我还能做些什么来解决这个问题？

更新：我的版本显然处于 18.04 和 19.04 之间，因此我已完全升级到 19.04 以修复该问题。但是，我得到了完全相同的 lshw 输出，以及 dmesg 中相同的 modprobe 错误。除非有人有什么好主意，否则我现在打算进行全新安装。
最后更新：在修复 XPS 9360 附带的杀手级 1535 卡的驱动程序失败后，我只能订购新的 wifi 卡（Intel 8265）。启动后，wifi 现在可以完美运行。
答案1
我在运行 Ubuntu 18.04 中的 5.0.0-37-generic 内核的 Dell XPS 15 9570 上遇到了这个问题。
作为churrov2有经验的

我做了什么杰里米31建议在评论中并运行
apt remove backport-iwlwifi-dkms
重新启动 Ubuntu，问题就解决了
