Arch Linux

Description:
netctl-auto frequently (every minute or so) drops the connection to my home wifi. The journal just says it's "by local choice":

```
Oct 09 11:22:03 kaul-laptop wpa_actiond[436]: Terminating wpa_actiond session for interface 'wlp2s0'
Oct 09 11:22:04 kaul-laptop kernel: wlp2s0: deauthenticating from xx:xx:xx:xx:xx:xx by local choice (Reason: 3=DEAUTH_LEAVING)
Oct 09 11:22:04 kaul-laptop dhcpcd[682]: wlp2s0: arp if_readrawpacket: Network is down
Oct 09 11:22:04 kaul-laptop dhcpcd[682]: wlp2s0: dhcp if_readrawpacket: Network is down
```

netctl-auto works fine at my university (eduroam) and it works fine with my phones hotspot. Also connecting to my home wifi works flawlessly using wpa_supplicant directly. (This is all on the same laptop.)
