When I installed Arch, I used wifi-menu. After installation I decide to install network-manager to use applet for wifi connection. My problem is my wifi router tells me that 2 computers has connection. Both of connections have the same Mac address, but different ip(last number, one has 3, second has 4).
My /etc/hostname:
some-name
My /etc/hosts
127.0.0.1 localhost
::1 localhost
127.0.1.1 some-name.localdomain some-name
First time I used start NetworkManager.service after that I enable NeworkManager.service

I don't now why, but after several reboots number of the connections became one
