我的 wifi 连接出现了一些问题。我认为下面这段摘录中最有趣的一句话是：
Direct firmware load for ath10k/cal-pci-0000:03:00.0.bin failed with error -2.
但我就是不知道该如何修复它。我已经下载了新旧固件sudo apt-get update/upgrade/upgrade-dist。
我的/etc/modprobe.d文件如下所示：options ath10k_core skip_otp=Y。
我见过许多人遇到相同或类似的问题，但按照这些帖子中的解决方案尝试要么不起作用，要么使情况变得更糟。任何帮助都非常感谢。只要我运行：
sudo systemctl restart network-manager我可以再次访问 wifi，但它会持续大约 2 分钟。

它可能缺少一些固件，但显然找到了可用的固件；否则，它根本无法工作。这是否是最佳固件是一个问题。让我们尝试升级固件。从终端：
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161_all.deb
sudo dpkg -i linux*.deb
重启并测试。请向我们显示：
dmesg | grep ath
