No, it was not. At the end were the lines

Why are your udev rules renaming wlan0 to that crazy string?
Your ESSID for the AP of "1.618029" is also strange, but that works OK here.
Note that I added the ML to this reply.

The ID didn't cause any issues before, neither did the strange names
(courtesy of systemd 197) and they are indeed very strange but as you
have already seen the same setup is working in 3.8.2
Here are relevant dmesg output in 3.8.2 //

so is there maybe a quick fix?
I have another idea, I should try out. Maybe I should try to disable
IPv6 in my network settings.

I see that had no effect. You need to bisect between HEAD and v3.8.

Larry, I'm very happy to report that after recompiling the kernel from
git master just a few minutes ago all is working again! Thank you very
much for your patience with my ignorance. (and all kudos to you, friend,
comrade, sister or brother....whoever you are on other end of the wire
who managed to fix this :)
So I'm off bothering Mighty Alan again until the other problem with my
usb hub in the display is solved :) Have to brace myself for another
round of awkward comments, I guess.
Thank you again! I will familiar with bisecting soon enough.
