Hi,

Right after booting when I try to join a network I get nothing:

May 13 17:25:22 nysa kernel: iwlwifi 0000:02:00.0: L1 Disabled; Enabling L0S
May 13 17:25:22 nysa kernel: iwlwifi 0000:02:00.0: Radio type=0x2-0x1-0x0

Over and over and over. It never authenticates.

Then if I enable ad-hoc mode in wpa_supplicant:

May 13 17:25:57 nysa kernel: iwlwifi 0000:02:00.0: L1 Disabled; Enabling L0S

Of course, I'm not interested in ad-hoc mode, but when I disable it
and try again:

May 13 17:26:19 nysa kernel: iwlwifi 0000:02:00.0: L1 Disabled; Enabling L0S
May 13 17:26:19 nysa kernel: iwlwifi 0000:02:00.0: Radio type=0x2-0x1-0x0

It works this way _every single time_. So I have to with with mode=1,
then with mode=0, _every single time_. It's very annoying and I've
tried everything; I tried with older kernels as far as 3.6.0,
different versions of wpa_supplicant, different module options. It
never works correctly.

Right now I'm on v3.9.2, and the problem is still there. I believe if
I restart the AP, it works, but I haven't tried many times. Also, I
haven't tried other APs (I don't have one readily available).

Any pointers?

Cheers.
