Hi,

Ok, just compiled and rebooted with new git checkout, but will recompile
with option again enabled.

I'm not sure if it is affecting the performance of your system overall. Are you using the power save option? And if so, what is the behaviour when power save is turned off?

I am not sure what you mean with power safe of the iwl driver. If I do
	iwconfig wlan0
I see
	Power Management:off
is this what you mean, and 
	$ cat /sys/class/ieee80211/phy2/power/runtime_enabled
	disabled
Is it what you mean?

Yes, that is on a differnet network. As soon as I can catch the log I 
send it.

> If you're up for it, I'd ask you to do one thing  (or three) -- open 3 separate bugs for the issues you're seeing at: bugzilla.intellinuxwireless.org so we can keep track of them separately. The issue of trying to activate an invalid station ID is definitely a new one, and likely due to a different cause than that related to aggregation or the troubles you're having even with 11n disabled. I could do this too, and add you to the CC list. I might need logs for these bugs, but not yet.

Sure, will do that.

Best wishes
