Hi @Violet Phan

root cause may be driver issue. please check the latest driver and install it.

Your driver version 22.0.1.5 is quite old. Intel AX201 drivers have been updated many times, with much newer releases available for Windows 11. Updating the wireless driver can improve performance and compatibility. [support.lenovo.com], [catalog.up...rosoft.com]

What to do

Open Device Manager
Expand Network adapters
Right-click Intel(R) Wi‑Fi 6 AX201 160MHz
Select Uninstall device
Check Delete the driver software
Restart
Install the latest AX201 driver from MSI support or Intel Driver & Support Assistant

Thanks.
