高通AR9285无线网络适配器在Ubuntu18.04.3LTS上的HP ProBook 4330问题
提问于 2019-10-01 17:21:13
- 硬件是HP ProBook 4330
- 软件为Ubuntu 18.04.3 LTS
几天前，WiFi适配器突然停止工作。
设置UI上写着“找不到Wi适配器”
一些CLI说

适配器被rfkill阻塞。在惠普笔记本电脑上，这种情况时有发生。以下是修复它的步骤：
- 确保您的笔记本上没有硬件无线开关，如果它存在，请打开它。
- 检查BIOS的无线选项并启用它。如果您没有无线选项，请尝试将BIOS重置为默认值。
- 如果没有任何帮助，请将运行在终端中的HP平台驱动程序列入黑名单: sudo tee /etc/modprobe.d/ blacklist -hp.conf <<<“hp_wmi”
然后重新启动。
