A basic command which i was using until yesterday have stopped working suddenly. until yesterday i was able to switch to my office profile with the command:

nmcli connection up Office ifname em1

But now i get this error message,

Error: No suitable device found: device 'em1' not compatible with connection 'Office'.

any reason why ?

Has the name of the device changed? Look at the output of

nmcli d

At first nmcli d didn't show any thing, so i restated the networkmanager service, and now the output is as this:

DEVICE   TYPE      STATE        
em1      ethernet  connected    
VLAN100  vlan      disconnected 
VLAN110  vlan      disconnected 
VLAN119  vlan      disconnected 
VLAN120  vlan      disconnected 
VLAN130  vlan      disconnected 
VLAN140  vlan      disconnected 
wlp3s0   wifi      disconnected 
lo       loopback  unmanaged  

but even then it didn't work, i got

# nmcli connection up Office ifname em1
`Error: Connection activation failed.

so then i did ifconfig em1 down && ifconfig em1 up, and for some reason it works again.
