Th= is is my second problem sent via email. Recently I have switched from manua= l wpa_supplicant and dhcpcd init scripts to NetworkManager (1.50.0), but I = am facing some trouble in doing so. The loopback interface lo works (set up= externally by an init script) but eth0 and wlan0 are shown as unavailable. My device does not have Ethernet plugged in, that maybe the cause for eth0 = being unavailable. But, wlan0 is stated as unavailable as well. root@mrrpos:[ / ]# ls -n /etc/rc.d/rcS.d=20 total 0 lrwxrwxrwx 1 0 0 21 Jun 10=C2=A0 2025 S00mountvirtfs -> ../init.d/mountvirt= fs lrwxrwxrwx 1 0 0 14 Jun 10=C2=A0 2025 S05udev -> ../init.d/udev lrwxrwxrwx 1 0 0 17 Jun 10=C2=A0 2025 S10modules -> ../init.d/modules lrwxrwxrwx 1 0 0 14 Jun 10=C2=A0 2025 S20swap -> ../init.d/swap lrwxrwxrwx 1 0 0 17 Jun 10=C2=A0 2025 S30checkfs -> ../init.d/checkfs lrwxrwxrwx 1 0 0 17 Jun 10=C2=A0 2025 S40mountfs -> ../init.d/mountfs lrwxrwxrwx 1 0 0 17 Jun 10=C2=A0 2025 S45cleanfs -> ../init.d/cleanfs lrwxrwxrwx 1 0 0 20 Jun 10=C2=A0 2025 S50udev_retry -> ../init.d/udev_retry lrwxrwxrwx 1 0 0 16 Jun 10=C2=A0 2025 S60sysctl -> ../init.d/sysctl lrwxrwxrwx 1 0 0 17 Jun 10=C2=A0 2025 S70console -> ../init.d/console lrwxrwxrwx 1 0 0 18 Jun 10=C2=A0 2025 S75localnet -> ../init.d/localnet lrwxrwxrwx 1 0 0 21 Apr 26=C2=A0 2026 S80dbus -> /etc/rc.d/init.d/dbus lrwxrwxrwx 1 0 0 31 Apr 26=C2=A0 2026 S85networkmanager -> /etc/rc.d/init.d= /networkmanager root@mrrpos:[ / ]# ls /etc/rc.d/init.d checkfs=C2=A0 dbus=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0 gpm=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 krb5=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0 mountfs=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 network-ifaces-up=C2= =A0 rc=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 setclock= =C2=A0 sysctl=C2=A0=C2=A0=C2=A0 udev cleanfs=C2=A0 dhcpcd.disabled=C2=A0 halt=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 loca= lnet=C2=A0 mountvirtfs=C2=A0 networkmanager=C2=A0=C2=A0=C2=A0=C2=A0 reboot= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 sshd=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 sys= klogd=C2=A0 udev_retry console=C2=A0 fontface=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 ipta= bles=C2=A0 modules=C2=A0=C2=A0 network.bak=C2=A0 random=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 sendsignals=C2=A0 sw= ap=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 template=C2=A0 wpa_supplicant root@mrrpos:[ / ]# nmcli device DEVICE=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 TYPE=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0 STATE=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 CONNECTION lo=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 = loopback=C2=A0 connected (externally)=C2=A0 lo=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0 eth0=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0ethernet=C2=A0 unavailable=C2= =A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0-- wlan0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 wifi=C2=A0 =C2= =A0 =C2=A0 unavailable=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0--=C2= =A0 =C2=A0 =C2=A0 =C2=A0=C2=A0 ... others are "unmanaged" ...
