在联想 Y530 上运行 Kubuntu 18.10。
就其本身而言,WiFi 连接和蓝牙扬声器工作正常。如果两者都运行,则会引入严重干扰。这首先导致 WiFi 连接下降到速度的 10% 以下(在某些情况下,上传完全失败),以及 BT 信号严重干扰/跳过。
我尝试设置options iwlwifi bt_coex_active=N
,/etc/modprobe.d/iwlwifi.conf
这完全禁用了我的 BT(编辑:见下文)。然后我将它设置为bt_coex_active=0
并删除了 Blueman(不确定它的删除是否重要),这解决了 WiFi 问题,但如果使用 WiFi,BT 信号仍然无法正常工作(仍然严重跳过)。
编辑:我现在尝试N
再次将其设置为,它与0
. 不知道为什么它以前不起作用。
在 Windows 上,一切正常。此外,如果我从手机连接到扬声器,一切都很好——这意味着它可能不是信号本身被卡住了(遗憾的是,我的路由器不支持 5GHz,所以我无法彻底检查)。我尝试更改 WiFi 频道,但没有任何效果。
可能是驱动问题,但使用 WiFi USB 适配器时也会出现同样的问题。可能是这样的,虽然这个适配器被声明为“正在使用”用于连接,但它并没有真正使用,而且 WiFi 仍在通过内置购物车进行 - 我不知道如何检查这一点。
这是这些问题通常要求的输出,请询问是否需要更多输出。谢谢!
