最近升级后,注意到 wifi 随机断开,速度在几秒钟内从 0.1Mbps 到 100Mbps 来回变化,可能会上升几秒钟,或者几个小时,无法预测。我正在尝试使用提交错误报告ubuntu-bug
,但我不知道哪个包有问题。
这可能是一些相关信息,但我查看了模块,没有看到类似的内容rtw_8821ce
,有些rtw88_*
模块可能相关,但无论如何,据我所知,我无法将它们映射到任何包。

这是我能找到的最好的参考:WiFi 频繁且随机断开连接, rtw_8821ce driver,但即使它位于“新手角”部分,我也无法遵循他们在做什么。就像“您是否尝试过仅使用 wpa_supplicant(以及 DHCP 客户端,如果需要)进行连接?” 远远超出了我的技能水平。
无论如何,如果有人可以帮助识别相关的包,我至少想填写一份错误报告。
根据要求,这是我刚刚重新启动的相关输出iwconfig
