I'll update it to indicate that UVerse 2wire routers seem to be the culprit.

I'll have to try some ARP spam tests later this week. It would be more evidence pointing to the wifi chip's "filters" being looser in KK6 than KH7, in addition to the BT-AMP bug.

I've got an idea that might fix many of the KK6 problems if that is indeed the case. Will need some time to investigate.

If there's any way I can help you with this on my end, let me know. I'm back home Friday and will be able to test whatever needs to be tested all day on Friday. That'd be aawesome if you find the fix!

Cool Some Dumps
Hmm, I have a 2wireRouter with ATT Uverse. Here are a couple of dumps running just a few minutes. If you would like longer dumps let me know.
I am running UnNamed 2.2.1 With the Entropy kernal

Sometimes I only use 50% power in a day,
Sometimes the power drains like crazy.
Of Course usually that is with Words With Friends which will eat up about 1% every 3 minutes.

I don't really think there was much difference for me with UnNamed 1.3 when I was using it.

Ok. Followed Entropy's advice and
1) went back to stock 2.3.4
2) Went to airplane mode to ensure no communication with big brother
3) Rooted
4) Removed bloat stuff (and device manager) using Titanium
5) unrooted

All seems well and my office network seems to still be operational. Thanks for your help.

I installed 2.3.4 on my phone last night using this site.

galaxys2root.com/att-galaxy-s2/how-to-unroot-att-galaxy-s2-sgh-i777/

I then ran my phone overnight and the power consumption went down to about 1.5% loss per hour. With 2.3.6 I was losing about 9-10% per hour.

I found that site a bit confusing. Maybe just me. The sticky right on XDA seemed easier to follow:

I also see significant improvement since moving back to 2.3.4 Following the procedure did not increment my flash count and all my apps, settings, etc. migrated without me having to worry about it (I did make a backup just in case). So far, I am glad to have done it and my fear of losing access to my company's VPN did not come true.

I don't understand...You went back to being 100% stock...then you rooted...then you unrooted? <-- Was this just to remove the OTA upgrade from stock? I don't understand why you didn't just stay rooted?

My company will not allow access to their VPN from a rooted device. So I rooted, removed the device manager to avoid future "upgrades to 2.3.6" and froze some of the bloat. Then I unrooted to ensure big brother did not kick me out.

Whenever ICS or a fix is provided to the battery problem, I can root again, activate the device manager and allow the upgrade. Basically, I decide when to upgrade and not AT&T.

If it weren't for my company's policy, I would have stayed rooted. (Fixing oops)

How do you perform step 5?
Can you provide the link to the instruction?

I assume you mean rooted.
