Even though I am presented with a list of available networks, my system
with the rc1 kernel is not able to connect to any of them.
It stops at the point where it tries to obtain an IP address.
I tried to delete the Profile of my WiFi and recreate it but no luck.
This issue is only with 3.9rc1, it worked fine with 3.6 to 3.8.2.

I am running 3.9-rc1 from wireless-testing, and both my RTL8187L and RTL8187B
can connect to WEP, WPA1, and WPA2 networks without a problem. At the moment, it
is not convenient for me to boot 3.9-rc1 from mainline, but I should be able to
do that tomorrow.
What kind of encryption are you using, and what is the USB ID for your device as
shown by the lsusb command?

As you can see, my system connected to a WPA2-encrypted network running 3.9-rc1
from the mainline tree. I do not know what problem you are having, but I cannot
reproduce it. My USB ID is different, but the chip is the same.

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 //

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.
