The problem is common on systems using a NetGear router with outdated firmware.

See this thread for the solution:
Computer Crashed when I wasn't around it.

Ok, I do have a Netgear router, but my firmware seemed to be up to date. I downloaded the latest firmware file anyway, just to be safe, and am uploading it to the router. It appears to be the exact same version. I'll report back if this fixes it or not!

Update - after some more reading, I uninstalled Netgear Genie, too. Hoping these two things are the fix!

Thank you.
