[解决了一半] 神舟战神笔记本 rtw88_8821ce 驱动蓝牙不稳定/断连/无法连接

hmeqo · 2025-01-15 18:50:04

开机几小时后已连接的蓝牙会出现声音断断续续有爆破音的情况，还有概率直接断开无法重连，类似下面这样，一般这时候蓝牙就连不上了如果还没连接的话

有没有可能是无线环境比较糟糕？

em有可能，周围电脑比较多的时候非常频发，但现在在家，之前win系统并没有这种问题

这本子网络控制器是这个 Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter，仔细研究发现用的驱动是 rtw88_8821ce / rtw88_8821c，并且这网卡是蓝牙和wifi共用
然后我尝试装了 rtl8821ce 驱动，用了几天，没再出现断连连不上的问题 (可能是因为还没用几天，这个bug比较怕生)，但是有了新的问题，rtl8821ce 驱动蓝牙和wifi同时连接的情况下，wifi网速会变得很慢，只有几百kb/s，蓝牙还没有遇到断连，但是并不是很稳定，玩游戏隔个几秒就小抽一下 (不知道怎么形容，类似掉帧)，想了想还是换回rtw88了

改用 rtl8821ce 驱动可以解决断连无法连接的问题，wifi 蓝牙同时连接网速慢理论上可以让 wifi 走 5G频段来解决，rtl8821ce 的稳定性最近突然变好了 (不懂怎么回事)，但是这个驱动不支持 qc45 多设备连接的功能，如果手机连接了蓝牙，电脑会断开，暂时还没测试如果蓝牙手柄+蓝牙耳机会发生什么

rtl8821ce 驱动连不上我手机热点可还行

倒是有一个办法能恢复蓝牙功能，快速重复运行下面的命令，直到出现错误，等几秒钟，再尝试重启蓝牙，如果没有报错，蓝牙就又能正常工作了，但治标不治本

❯ sudo systemctl restart bluetooth
Job for bluetooth.service failed.
See "systemctl status bluetooth.service" and "journalctl -xeu bluetooth.service" for details.

这时候看日志会看到这个
