FYI: I've asked this on Superuser but not luck so I'm trying here.  I'm not sure which it is more relevant to.I have a hard-wired Ethernet card/cable to my hub.  I start Fedora 23 but there's no network, why?  So I've checked that the card exists:-[root@localhost ~]# lspci | grep Ether00:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
