journalctl for troubleshooting unexpected freezes and awaking errors

I'm experiencing some problems with Arch that I didn't have with the Debian-based disto I was using before:
complete freezes that only clear with a hard reset;
doesn't wake up from sleep, but not all the time - also only cleared with a hard reset;
rarely, but wi-fi disconnects and can be connected again after a couple of seconds;

What would be the appropriate commands for journalctl to check:
the last freeze that occurred;
awakening from sleep issues;
wi-fi issues;

Try to avoid that, you'll lose the log.

rarely, but wi-fi disconnects and can be connected again after a couple of seconds;

That can have all sorts of reasons, please post your complete system journal for a boot covering such incident:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

If you can reboot w/ the magic sysrq (nb. that you've to explicitly enable the feature first!) a journal of the previous boot might show what went wrong: 

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st
