I figured the issue was a problem with my wifi router, but after much
debugging I don't think that's the case. I have a new (Arch) linux
server I built a few weeks ago. What seems to be happening is that my
server crashes for some reason - and then looks like it's causing the
ethernet LAN switch inside my router to stop working. (I verified
that when I unplug the server's network cable the router starts
working again, and when I plug it back in the router stops.)
When it crashes, instead of reconnecting router connect any laptop with
arch booted from usb. If link comes up then use tcpdump to see what is
happening on the wire.
