我的 Qualcomm Atheros QCA9377 无线适配器无法工作。因此我无法在 Ubuntu 20.04 版本中使用 WiFi。此外，我的笔记本电脑供应商是联想（型号：E41-25）我已经在 AskUbuntu 上参考了一些解决方案。
我可以在 Windows 中使用我的 WiFi 适配器，但不能在 Ubuntu 中使用。
我搜索了这个问题超过 4 个月但仍然没有找到解决方案。
请帮忙寻找解决方案。

答案1
内核引导加载程序中是否有acpi=off任何其他参数？acpi
如果是，请改用acpi_osi=!。
答案2
请在终端中尝试以下命令。它来自这里。
sudo apt-get update
sudo apt-get install build-essential linux-headers-$(uname -r)
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf

sudo reboot
答案3
嘿，我遇到了同样的问题，我所做的是从 /etc/modprobe.d/blacklist-ath_pci.conf 中删除 ath10k_pci。使用以下命令：
sudo nano /etc/modprobe.d/blacklist-ath_pci.conf
然后删除 ath10k_pci
答案4
解决方案
进入 BIOS
再次启用 PXE Boot 重启。
再次进入 BIOS，将 PXE BOOT 设置为第一优先级，然后是操作系统
保存并退出。
解释
- 将 PXE 启动设置为第一启动。
- 将启用/准备硬件。
- 然后，保持 OS 处于启用状态。
