This is the latest that Jenkins (the build bot) just finished a couple hours ago: http://www.mediafire.com/?l3yohua7i04et8s

Still shows 5-29 in the file name, but the source was pulled just before midnight. The change log API is down so flash at your own risk as always. Been working smoothly for me though. :)

Edit: you may have to load the download page twice to get the download link to work.
[AT&T Samsung Galaxy S II SGH-I777] :
Mine saves to the SD card when set to SD. Even checked the file path, had to go through EMMC to get to it. When set to "Internal" is when mine saves to the internal storage.
[AT&T Samsung Galaxy S II SGH-I777] macropterous:
I have been experiencing this problem but only on 5.29(1) reverting to 5.19 solved the problem. I am currently loading 5.29(2) and will post back if I have any info.

UPDATE: 5.29(2) - still losses wifi connection on heavy sleep.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Nope.

Exactly. With the exception of "dirty networks" and the dreaded BT-AMP bug (haven't seen it in months), leaving wifi on should improve battery life and does for me.

Cannot reproduce.

My device had wifi working fine this morning after leaving it sit for... 10-12 hours?

0529, Freeze on power button wake

0529 freezes on power button wake for me. I use widget locker.

Flashing back to 0519 and everything works again.

Bluetooth did work again in 0529 though. It would connect briefly in 0528 but then drop and reconnect in a loop.
[AT&T Samsung Galaxy S II SGH-I777] macropterous:
I noticed that the wifi did not lose its connection if the handset was connected to a power source. When the system went into "deep" sleep while disconnected from a power source, it lost the wifi connection every time; I had to toggle airplane mode to reconnect.

5.19 is still the most stable build for me.

[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
I guess wifi drop is experienced only with AP, not with directly WiFi Router.Can those that experience confirm?

WiFi Router -> AP1 -> AP2 ( phone is on this AP)-> AP3 = issue

WiFi Router ( phone is on) = No issues

If so, it may be related to AP's local settings, Is that right?

Entropy,

Is there any option you are considering to rollback N7000 Update 3's wifi drivers in case it has brought in more issues rather than fixing many.Just curious.

Update: I got your feedback on 9100 forum that you would work on wifi driver thing, keep my fingers crossed~

Elherr,

Did the AP's have different SSID's when you had trouble with wifi dropping?

Ans: I did not have this issue with 0527 on single wifi router, never had chance to use 0525 and above on APs but for some other reasons I fell back to 05/24.
[AT&T Samsung Galaxy S II SGH-I777] elherr:
I've only been connecting to wireless routers so far and have had no issues. I'll see if I can drop by an office with AP's using 802.1x & hidden SSID. With 30+ AP's in the office I'd hope I could reproduce the problem.

Did the AP's have different SSID's when you had trouble with wifi dropping?
[AT&T Samsung Galaxy S II SGH-I777] aznkenshin:
Same here. My phone freezes upon unlock and I can't drag the unlock circle around. As if it's unresponsive. Wasn't like this on the 5-27 build.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
Yes, Entropy is installing his AC, then he will look into it, if you want quicker results go install his AC for him :p

In the mean time, see if you can get him a logcat of it, instructions here: http://teamhacksung.org/wiki/index.php/How_to_report_a_bug
[AT&T Samsung Galaxy S II SGH-I777] elherr:
AC? As in air conditioning?

Thought bug reports on nightlies were verboten? ;-)

I'd grabbed logcat output before and nothing really stands out. OpenGL cache flush timing?

http://xdaforums.com/showpost.php?p=26710572&postcount=2724

Since then I've changed wifi sleep policy to always on and the problem persists -- perhaps even worse.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
Yes, AC is air conditioning, he posted about it in another thread, I guess he can't work well while melting.
[AT&T Samsung Galaxy S II SGH-I777] elherr:
Haha. He needs to move out to Seattle like Mr. Kondik (Cyanogen). Never a worry about high temps here.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
I get where hes coming from, I work in a server warehouse which is kind of like a freezer, it's almost the opposite where it's too damn cold to work.
[AT&T Samsung Galaxy S II SGH-I777] TheDude:
I have 4 AP's in my home and wifi was such a mess on my device that I actually quit using it except when required. ATT was nice enough to put a tower in my backyard so my signal and data is perfect but my view is screwed ;) Oh well

Since the latest update I can report that traversing AP's is working perfectly and I am now back on wifi! I have my device set to "keep wifi on during sleep only when plugged in" so it varies for me. I experience what you are describing but it seems that if I give it a little bit it works itself out. Personally if it gives me problems I just turn the damn wifi off and go about my business.

I have also unlocked my device to find no wifi icon at all even though it is enabled and obtaining ip address. Typically requesting data somehow has re-established my wifi connection (eg. accessing a web site). Kinda strange. The same applies to the white icon after deep sleep. Request some data and in short time it re-establishes the connection. I really have not had to toggle wifi on and off much as mine seems to connect before I have the chance to experiment. It is not perfect but much better than before imo. Previously, with multiple AP's I had to toggle data on and off so much to connect to the closest AP it was not even worth using it. Now I have full wifi bars anywhere on my property!

So in short, yes I have the same problems and it very well could be related to roaming aps. I don't know anything about the interworkings of the latest wifi driver but it almost seems that it connects by MAC address which can cause issues if you are far from the AP with just enough signal to connect but not enough to transfer data. If it connected by SSID with strongest signal strength we would have a winner! Wifi Analyzer correctly sees all my AP's so it must be something with androids connection logic. There is an APP on the market that proclaims to fix this ( https://play.google.com/store/apps/details?id=org.wahtod.wififixer ) although I have not tried it yet. I figure the CM team will address this in time and all will be well as we are now moving in the right direction.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
Unfortunately the wifi drivers remain closed source and Broadcomm isn't known for their top quality work, so issues with wifi aren't likely to ever be completely solved, I do agree with you that things are getting better now, hopefully this means that the folks at Broadcomm have decided to extricate their heads from their asses, but I wouldn't count on it.
[AT&T Samsung Galaxy S II SGH-I777] elherr:
Yes indeedy. Substitute telephone company central offices for me. Many HVAC's moving waste heat from routers, switches, etc.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
I can see my breath in here today, it's like 80 degrees outside and I'm very glad my lab coat has long sleeves cuz its freakin cold in here!
[AT&T Samsung Galaxy S II SGH-I777] TheDude:
So the issue has been tied to driver level? Again, I have spent little time with this and its just speculation but it almost "feels" like the os is not telling the hardware what to do properly in regard to the connection state and method.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
Well, I'm sure it's both, the problem with closed source drivers is, it's hard to figure out how the OS is supposed to talk to the driver and what the responses of the driver mean, that doesn't mean that work outside the driver can't make it better, but it is made harder by the fact that if the bug is in the driver it is next to impossible to track down and even harder to fix.

I'd be interested to see if the app you linked actually fixes your problem, because if it does, it means there may be more that can be done on an OS/software level to fix the issues, if it doesn't, then we're back to the driver being the ultimate culprit.

The latest release of this ROM is better than AOKP, at least on my phone. It feels smoother and the performance seems to be better as well.
[AT&T Samsung Galaxy S II SGH-I777] herofmm:
I came from Aokp 3/25. Both are stable and fast. But it seems Cm9 3/29 gives better battery( just been 4 hours). Couple of small things are gps on google map does not work now and I miss aokp's notification toggle.
[AT&T Samsung Galaxy S II SGH-I777] robotohshs:
I came from the latest release of AOKP and I like this new CM9 release. Its more smoother

:D
[AT&T Samsung Galaxy S II SGH-I777] Snow02:
If you're using the phone more, which you probably are with flashing new stuff, of course it's going to be awake more ;). But use better battery stats to check wake locks, as suggested previously.
[AT&T Samsung Galaxy S II SGH-I777] :
I came from AOKP, too. And while I miss a couple of the extra settings, CM9 3/29 is by far my phone's favorite ICS so far. It runs better for me than CM7 ever did. Better battery for me than AKOP, too. But as they say, every phone is a little different.
[AT&T Samsung Galaxy S II SGH-I777] mrRobinson:

I noticed my phone wakes much more often when WiFi is on, caused by Google Latitude. When WiFi is off, it wakes much less frequently.

I guess Latitude acts differently with WiFi on vs off.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Well, these wifi drivers do have source - but they're uncommented, there is no documentation for the underlying chipset, AND Samsung performs unknown customizations to them - with no change history available to us.

I don't think I've ever seen a completely functional BCM4330 driver that didn't have SOME sort of drawback.

For example, the new driver:

1) Adds AP roaming

2) Fixes packet filters so that my device does not get woken up by unrelated ARP traffic (e.g. isn't affected by my arpdrain stress test)

3) Reliably loads without weird memory allocation issues that almost always lead to an SoD after it loads

The disadvantage:

1) The touchscreen resume issue. Since it can be worked around (unlike 3) ), it's vastly preferable to try and fix this one glitch rather than revert the driver. There's a few possible things to look at.
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
Ok, well that's just about as bad as being closed source, source without documentation doesn't make it any easier to figure out. And you're right, the benefits of the new driver outweigh the current drawback, especially since hitting the power button again seems to solve it.

Latitude is a piece of crap, if you don't absolutely need it, I suggest remaining logged out.
[AT&T Samsung Galaxy S II SGH-I777] hi2u2:
Was it plugged in during this whole time? The wifi dropping I'm seeing only manifests during deep sleep.

It happens no matter if I'm connected to the main router or the AP. They're both running identical firmware (Tomato) and settings are identical, except one has DHCP disabled.

Can someone tell me which log would be useful in diagnosing the wifi drops? AFAIK, last_kmsg is for spontaenous reboots, wireshark is for battery drain, and logcat wouldn't be useful as it would be holding a wakelock, and the problem doesn't show up unless the phone is in deep sleep. Thanks.
[AT&T Samsung Galaxy S II SGH-I777] elherr:
You should still see events in log prior to entering sleep and then also on resume.

To filter logcat output you can use 'grep' (Global Regular Expression Parser).

'logcat -v time | grep wlan0' would be an example in ADB shell.

Edit: I have not been able to replicate wifi drops.

'dumpsys' appears to be a neat utility. I'm still looking at what is reported... more to learn.
[AT&T Samsung Galaxy S II SGH-I777] apanihi:
I got tired of all the weird issues I was having so I did a factory reset and started fresh with 5/29. Restored fresh apks for all my apps and now Wi-Fi seems to be OK and having no need for Airplane Mode On/Off. I'll keep checking it to see how it goes.

wifi sleep policy doesn't work in cm9! Maybe that's why you didn't see the problem go away?

The setting to change sleep policy is visible in advanced wifi settings, but it doesn't do anything.... wifi will be on during sleep no matter what :(

Quick question. when there is a nightly with the same build date do you guys install them both or just the latest one?? I know that the md5 sum numbers are different that's why Im asking. thanks in advance
[AT&T Samsung Galaxy S II SGH-I777] thracemerin:
In this case the 2nd 0529 build is actually the 0530 build, because of some odd timezone shenanigans between the jenkins server and get.cm it show 0529, in general if there are 2 from the same day the newer one is either a situation like this or was built because of some sort of game breaking bug in the previous nightly from that day, either way install the latest.

[AT&T Samsung Galaxy S II SGH-I777] PR-0927:
Is anyone else having the wrong ringtones play for the wrong people? I made sure after the incorrect playbacks that it was set correctly. Still happened. Confused me quite a bit.

Any idea on how to fix this?

I copy a "media" folder into system/media with my ringtone and notification audio files either before or after flashing to get them to show up. Never gave me problems, ever. But this time I had copies sitting in the "Ringtones" folder on the internal SD card (default view area).

Removed them from there but I think it still acted funny after that too.
[AT&T Samsung Galaxy S II SGH-I777] naturefreak85:
I don't think it's just you. I have a similar issue, I'll get a lock but soon after the GPS will lose it's location. Navigation will lose all fix data and not reload it. I tested with GPS Status, and once the initial Fix is obtained, it doesn't seem to update. This has existed since at least mid May, but until today I didn't need to use GPS. I'm about to flash back to an early May build and use it for this weekend which I will need it for.

Especially since now that I'm on 5/29 when my phone is connected to WiFi if I turn on the screen the touchscreen won't respond right away all the time. Totally random.
[AT&T Samsung Galaxy S II SGH-I777] pmgnet:
Excellent! I just flashed the 0529 – two build And the lock screen problem is gone. I have not tried this specific build, my issue with the lock screen was with the original 0529 build.

I had flashed back to 0519 and now to this latest build. Everything seems to be working great GPS lock screen Bluetooth et cetera.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Nope, I'm not one of those people who leaves my phone sitting on the charger all night.

Right now - just wait, there's a possible fix for the touchscreen stuff which might fix other wifi issues too that is being tested. We're being paranoid about it since it involves pulling parts of the N7000 MMC drivers - while we THINK we know how to render this driver safe we're being careful. However GM did a similar thing with Siyah and there have been positive reports so far.
[AT&T Samsung Galaxy S II SGH-I777] naturefreak85:
EDIT: Under 5/30 the GPS issue seems to be resolved.

I can say with certainty something is off with the GPS as of 5/29. I will test 5/30 on my way home but with 5/9 there is no sensor issues. I tested the issue with GPS Status, when a fix was established the sensor stops reporting the location to CM9. When using GPS Status the outer ring of the compass would stop moving no matter what direction I was facing and the lat/long was not updated in later CM9 builds. Under 5/9 it tracked me perfectly and the outer ring moved, lat/long was also updated over 10 minutes of driving whereas with 5/29 after 15 minutes it still showed my original fix location. I will edit this when I get out of work tonight with 5/30.

NFC

Have been trying to test the NFC ability on my Samsung I777 with the CM9 nightlies containing the NFC software. The tag software seems to work but when I try to read a RFID tag in my driver's license, it does have one, nothing happens. The system settings show it active, z-device test shows it enabled, but cannot read my Mobil speed pass RFID, driver's license or Nexus Card. Am I doing something wrong or something else.

I did do a complete wipe and reinstalled all programs, CM nightly, etc. after NFC was added to CM9.

[AT&T Samsung Galaxy S II SGH-I777] naturefreak85:
Very few RFID chips can be read by the NFC in your phone. NFC is based off RFID IIRC but not compatible with most RFID chips. You need to buy NFC tags to take advantage of it until NFC based payment software is available.

With light usage I'm getting less than 1% drain per hour. That's friggin awesome!
[AT&T Samsung Galaxy S II SGH-I777] sir_dwtc:
I had been getting frustrated that nothing I owned seemed to use NFC (which is probably good as far as the credit cards go). Even my passport, which was issued in 2007, and has warnings about how you shouldn't fold it or get it wet because of the electronic chip inside, doesn't even register anything at all with any NFC apps.

But then I found a badge from a trade show I attended last year, where the exhibitors would touch a phone to the badge to scan it. Holding my phone over the badge does pop open an NFC app, although the actual contents of the badge can't be read without knowing the encryption keys.

Moral of the story: you never know what you'll have that's NFC-compatible, until you scan everything you own. But until you buy your own tags (as you mentioned), it will be a pretty useless feature, even when you find stuff you can scan.
