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. Regards, Łukasz
