wireless modules not loaded after suspend?

[Joe Barnett]

On mantic, after a suspend my network doesn't come up automatically. I have historically run the following to "reset" networking; not sure what of it is necessary and what's not, but this brings it up:

$ sudo systemctl stop NetworkManager.service; sudo rmmod ath10k_pci ath10k_core ath; sleep 3; sudo modprobe ath10k_pci ; sudo systemctl start NetworkManager.service

rmmod does complain that none of the ath* modules are currently loaded, so perhaps that's why the network doesn't come up automatically?

This may be related to this file that I had set up at some point (to workaround some suspend bluetooth issues?):

$ cat /usr/lib/systemd/system-sleep/bluetooth
#!/bin/sh

case $1 in
  pre)
    systemctl stop NetworkManager.service
    rmmod ath10k_pci ath10k_core ath
    btmgmt power off
  ;;
  post)
    btmgmt power on
    modprobe ath10k_pci
    systemctl start NetworkManager.service
  ;;
esac

... at least that would explain the unloading of the modules, but not sure why the `post` section isn't reloading them?
