我在一台全新的电脑（Lenovo Thinkbook 13s，大约两个月前，ubuntu 22.10）上遇到了一些 wifi 问题，我认为它附带的无线适配器有缺陷，因为它偶尔会停止被识别，甚至不会显示在 lspci 上（通常是在 ubuntu 从睡眠状态唤醒时发生一次严重崩溃之后，这种情况在这台机器上很常见）。它是双启动，有时甚至不会显示在 Windows 中，所以我认为这一定是硬件问题。
我的解决方案是购买一个便宜的 USB 无线适配器 (Ralink MT7601U)，据说它与 Linux 兼容。我之前看到的所有关于此适配器的帖子都很旧了，而且看来驱动程序已经成为内核的一部分很长时间了。它开箱即用（出现在 lsusb 上并可以显示网络，但无法连接），但经过一番摆弄后，它终于开始工作了，虽然我不确定到底是什么修复了它。现在它偶尔可以工作，但有时会回到显示网络而无法连接的状态。
飞行模式已关闭，网络密码正确，已尝试将其关闭并重新打开。其他人有这个问题或有什么想法吗？
