As it says in the title. Doesn't matter if it goes into auto-sleep from inactivity or I manually tell it to sleep, computer immediately wakes itself up.
I've recently re-set up my computer in a new apartment, which means it was recently updated. I also had to purchase a USB wifi dongle, but I attempted the same steps after restarting with the dongle removed, so I'm fairly certain that isn't the cause. The logs posted below are from the dongle-less test.

Towards the bottom you can see it goes straight from Operation 'sleep' finished. to system is resuming / wake requested - is NetworkManager requesting the wake?
