Fix "unmanaged" network interface if it worked before

**TL;DR;** Maybe I clicked vpn connect wrong and got disconnected from the network. That's why the answer is easy. As usual I wanted to connect to my work network using ipsec via network manager applet. Previously it worked ok but this time after I press "connect" - networking stopped working completely. All my network interfaces are "unmanaged". I tried restarting my laptop - didn't help. I see only solution to reinstall my NixOs (and not even sure if this will help). I tried: * Manually "managed yes" my wlp59s0 interface. * Restarting services: NetworkManager, wpa-supplicant, strongswan. * Add unmanaged=no to the 10-globally-managed-devices.conf I checked journalctl and didn't see anything strange. System info: * Linux 6.6.6 * Network controller: Qualcomm Atheros QCA6174. * Os: NixOs unstable. nmcli device: wlp59s0 wifi unmanaged -- ip a:

wlp59s0:  mtu 1500 qdisc noop state DOWN group default qlen 1000
...

I tried up it - didn't help. I'll repeat one more time that wifi and tunnel worked fine for several days (before I used openvpn, also Ok), then one click - nothing works. Only ping localhost works :( How this even possible?
