ifconfig -a가 eth0 대신 br-ba165999130f를 표시합니다(이더넷 작동).

케이블을 사용하여 PC를 라우터에 연결하고 WIFI USB TP-LINK도 연결했습니다.

-a를 확인해보니 인터페이스 ifconfig가 없다는 것을 알았습니다 eth0. 대신 첫 번째가 호출되는데 (WIFI USB를 뽑아도) br-ba165999130f인 것 같아요 .eth0

그 이유는 무엇입니까?

그건 정말 옳지 않아요. 인터페이스br-ba165999130f가상 브리지입니다. 당신은 찾을 수 없습니다eth0이제 더 이상 방법이 바뀌었기 때문에udevd, 이더넷 장치에 이름을 할당합니다. 이제 장치 이름은 다음에 따라 지정됩니다."예측 가능한 인터페이스 이름 체계".https://wiki.debian.org/NetworkInterfaceNames

귀하의 경우 전자eth0인터페이스입니다eno1en=이더넷. 인터페이스가 가상인지 실제 장치인지 표시하려면 ls -la /sys/class/net을 수행하면 됩니다. 모든 인터페이스가 나열되어 있습니다.

이 인터페이스는 가상입니다.

이 인터페이스는 PCIe 네트워크 장치입니다.

드라이버가 올바른 드라이버가 아닐 수도 있습니다. lsusb 아래에 스틱이 나타납니까?
