Solved

Hello everyone,

I wanted to change my MAC address, so I used the commands:

$ nmcli connection down "The connection name" $ nmcli connection modify "The connection name" ethernet.cloned-mac-address 06: 00: 00: 00: 20: 05 $ nmcli connection up "The connection name"

I can successfully disable the connection and change the MAC address, but once the third command is executed, I get the error "The network connection activation failed" as an error message. I should mention that I do not have a Wi-Fi card; I am connected via Ethernet.

Hello,

If you're only configuring this for your connection "The connection name," I’m not surprised it's crashing.

  • What about the IP configuration?
  • Is it static or obtained via DHCP?
  • Is it a wifi or ethernet connection?

Here's an example here for a static configuration. And another example here for wifi.

Good luck
