fedora 22 does not detect wired network
I changed my ADSL2+ router from TPLink to DLink and after that my Fedora 22 machine stopped detecting the wired network. It says 'cable unplugged' while the wire is actually very much plugged in. The wi-fi however is working fine. I have tested the cable and the sockets of the router, they are okay.
You need to check your ADSL configuration, have to asume with all one network card did work, so it maybe a config on your ADSL
Other machines running Windows are working fine with this ADSL router. And on the machine running Fedora, the wi-fi is working with the same router.
Assuming you are using the NetworkManager to configure your connections, try to delete the configuration in the NetworkManager and reconfigure the wired network from scratch.
