If I plugged the ethernet cable off and plugged in again, the system network won’t reconnect to internet through ethernet (but will recognize it as plugged in, as shown in system report). Currently I found the only way to solve this is to reboot. But it shouldn’t behave like that. Wifi works normal but I mainly use ethernet.
This scenario only happened after I updated to Sequoia 15.1 Beta. I never encounter this kind of problem while using formal version of os release before.
