Hello @Peter_Eles,
After some searching, unfortunately, this wireless chipset “Broadcom BCM43142” is not supported properly in most of the kernel versions.
I would suggest you get a USB WiFi dongle for this laptop, you may reference this list: https://elinux.org/RPi_USB_Wi-Fi_Adapters#Working_USB_Wi-Fi_Adapters
In the meantime, I am reporting this issue to the Endless Engineering team, hopefully, this will be fixed in future releases.
