Hello,

Sorry for the late reply. I was using just wpa_supplicant. I also tried
wicd, but it seems to hang when connecting to a network, but my
understanding is that it's just a wpa_supplicant manager. I got this
while installing Gentoo, but I also reproduced it on the Fedora 20 Live
CD. See https://bpaste.net/show/7d5ad99260a7 for logs, but it doesn't
seem to say much more than my original extract.

What I found out in the meanwhile, however, is that active traffic will
prevent the issue from occurring. This happened with the Fedora Live CD,
but pinging the AP is also sufficient. I noticed iwconfig reports that
the power saving mode is off.

For what it's worth, I compiled my kernel and iwlwifi module with
tracing on, so tell me if I should try that.

Laurentiu
