Remote Samba share will not mount at boot time

edit

• I am running Fedora25 on an Intel NUC with a WiFi internet connection.
• I want to mount a remote Samba shared directory automatically during boot.
• The mount fails with "mount error(101): Network is unreachable" (see log below)

Here is my /etc/fstab entry:

//192.168.2.150/music   /home/music/Music   cifs    ro,auto,username=music,credentials=/etc/.smbpasswd,_netdev  0   0

After boot, I can successfully mount the share like this:

sudo mount /home/music/Music

• I was able to mount an NFS share using Fedora24 with no problem
• When I tried mounting an NFS share using Fedora25, I got the same results as I did with the Samba share
• From the log, it appears that the network connection is not available even though the Network Manager Wait Online service says that it is.

Any advice on what to try next?
