From the logs the Pi is trying to initiate AP which is bogus. I assume that you have wpa_supplicant.conf with your wifi settings.
I wonder the output from:
sudo vcgencmd get_config int
sudo vcgencmd measure_volts

All previous versions of volumio works without any problems. Even last version 3.569 works ok, wifi starts normally with system startup. After upgrade to 3.601 there is no wifi, only external usb ethernet adapter works ok.
@ms4sman or anyone else, should you have a usb-to-eth adapter at hand, could you try a log?
I see @dgcracker has one, that would be helpful.
Can you check the firmware date:
sudo dmesg | grep brcmf
Line like this one:
brcmf_c_preinit_dcmds: Firmware: BCMxxxx/x wl0:
sudo dmesg | grep brcmf

Which log do you need? I have a usb to eth adapter.
This is interesting.
Can you add to the /boot/cmdline.txt before rootwait additional over_voltage=2 and reboot?
This is actually failing on device wait.
yes, found that one too, we are discussing this. This would be the main issue.
problem found and fixed
you can enable test mode and update to the beta v3.607, or flash the image
