参考までに：この質問はすでに受けています根しかし、運が悪いので、ここで試してみてください。どちらがより関連性があるのかよくわかりません。
私のハブには有線イーサネットカード/ケーブルがあります。 Fedora 23を起動しましたが、インターネットなし、なぜ？だから、カードが存在することを確認しました。

その後、ネットワークを起動しようとしています（注意してsystemctl restart network.service出力は同じです）...
[root@localhost ~]# service network start
Starting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
[FAILED]
systemctl status network.service提案されたコマンド（上記）の結果は次のとおりです。
[root@localhost ~]# systemctl status network.service

次に、ここでいくつかの提案を見つけ、ネットワークスクリプトの内容を確認し、ifcfg-enp0s11ifconfig -a、上記で失敗した項目が私が探しているアドレスのようです。 MAC アドレスは、そのデバイスにリストされているアドレスと同じです。
[root@localhost ~]# more /etc/sysconfig/network-scripts/ifcfg-enp0s11
HWADDR=00:13:D4:86:EB:18
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s11
UUID=b7fce5e7-b3aa-4e95-a014-8661889e9cce
ONBOOT=yes
Webスクリプトの他のオプションは次のとおりです。
ifcfg-enp0s11 ifdown-ippp ifdown-routes ifup ifup-ipv6 ifup-ppp ifup-tunnel
ifcfg-lo ifdown-ipv6 ifdown-sit ifup-aliases ifup-isdn ifup-routes ifup-wireless
ifdown ifdown-isdn ifdown-Team ifup-bnep ifup-plip ifup-sit init.ipv6-global
ifdown-bnep ifdown-post ifdown-TeamPort ifup-eth ifup-plusb ifup-Team network-functions
ifdown-eth ifdown-ppp ifdown-tunnel ifup-ippp ifup-post ifup-TeamPort network-functions-ipv6
ところでifup eth、、、、、みんな構成が見つからないと言いましたね ifup eth1？ ！ifup eth2ifup enp0s11ifup lo
[root@localhost ~]# ifup eth
/usr/sbin/ifup: configuration for eth not found.
Usage: ifup <device name>
ifupNetworkManagerが実行されているため、これらのコマンドは実際には使用されていないことを部分的に理解しています。
[root@localhost ~]# systemctl status NetworkManager.service

なぜインターネットがないのかご存知ですか？
