Hi Oliver,

i'm using the *very* latest 3.4-merge tree from Linus and my Wifi now needs
more than one minute to connect to my access point.

[   16.288562] wlan0: authenticate with bc:05:43:94:1a:da
[   16.299644] wlan0: send auth to bc:05:43:94:1a:da (try 1/3)

This is an odd message. I need to figure out how that can even happen.

What's the beacon interval on your AP? It seems more likely that this is
a problem with RX though.

Hi Johannes and Amit,

pointing to the RX path was a good idea!

I checked the commits of the last three weeks and discovered that it turns
out that the patches from Amit caused the regression:

iwlwifi: add testmode command for rx forwarding

iwlwifi: fixed testmode notifications length
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=8e81f65fdc7f5d292bb3c115b748767d921823c1

I reverted them in the opposite order (of course) and now the issue is gone.

Regards,
Oliver
