我可以完美地在手机 (Pixel 6 Pro) 上连接到 WiFi 热点，问题在于直接连接到路由器，无论是工作路由器还是我家里的路由器。提到的两个路由器分别是 TP-Link AX6000 和 ASUS RT-AX92U；如果故障排除需要，我拥有这两个路由器的管理员权限。
问题是，虽然我最终可以连接到有问题的路由器，但与有线连接或移动热点相比，连接速度非常慢。（下载速度慢 76.95%，上传速度慢 99.64%）
我的系统中的网络接口是 RTL8852AE；我使用过rtw89对于驱动程序，安装过程中没有发现任何异常，除了以下内容：
$ make
make -C /lib/modules/5.15.0-52-generic/build M=/home/richie/test/rtw89 modules
make[1]: Entering directory '/usr/src/linux-headers-5.15.0-52-generic'
warning: the compiler differs from the one used to build the kernel
The kernel was built by: gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0
You are using: gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0
...
然而此后它似乎仍继续安装。
尝试连接路由器时sudo dmesg -W | grep wlp2s0返回：
[14095.433767] wlp2s0: authenticate with f0:2f:74:2d:70:50

...
重复多次，然后连接或放弃。无论相关网络是否有密码或是否开放，此输出都是相同的。
如果我可以连接到路由器，sudo dmesg -W | grep wlp2s0则会产生：

这是我的第一个 SE 问题，我不确定需要什么信息，所以如果信息太多或太少，我深表歉意，无论如何我都可以进行编辑。
答案1
您可以一次禁用一些驱动程序选项，然后重新启动并尝试再次连接。
您可以创建一个文件/etc/modprobe.d/50-rtw89.conf，然后一次添加一行：
options rtw89pci disable_aspm_l1=y
options rtw89pci disable_aspm_l1ss=y
options rtw89pci disable_clkreq=y
如果您的路由器有 2 个无线接入点，您可能还想选择 2.4Ghz 无线接入点，而不是更快的 5Ghz 接入点。
