[KERNEL] [TEST] CyanogenMod 6

A test/stock anykernel for CM6 inc is up on rom manager under the Koush section. Please test it out and let me know how it compares. I am working on tracking down some instability issues.

Having issues with built in tethering says error. Pre 9 seems to work however after toggling wifi.
Anyone else?

Used it for a day...
I'd have to say one of the biggest downfalls was that it didn't have most features within the kernel enabled. I didn't notice any immediate problems even with the stock kernel, unless what I ran into (described below) might be involved.
When trying to initially download the new kernel via ROM Manager, I was in a location where cell was -120 dBm (basically non-existent) but I had Wifi. Wifi always seemed to take forever to link up, unless I went into settings (then it'd find the AP immediately and connect). ROM Manager basically said it couldn't do anything, despite having Wifi. I don't know enough about the inner Android workings to know if that's unrelated or not.
With the new one I noticed mainly I had very few governors to work with. TBH I only spent a day with it because I couldn't stand how often I ended up having to charge it. I don't OC so that sort of thing has never been an issue - just UC
Edit -- I should mention I'm using 2.15.00.09.01 baseband and CyanogenMod-6-09202010-NIGHTLY-Inc build. Haven't tried newer dailies yet.

2.15.00.09 radio literally KILLED my battery. I went back to 2.15.00.07 and battery life is great again. FYI.

Everything is good for me with this kernel. No issues. Flashed it last night.

At the moment, I'm using Miui but wanted to note that this is the only kernel which allows Pre-9 Wifi tether to work on Miui (in my hands, King's #1 and #2 AOSP kernels gave me errors with Wifi Tether). Thanks for providing this kernel, Koush. Will give it a try with CM and see how that goes.

I had a soft reboot last night with this new kernel while I was on facebook. 0 wifi used.
Radio 2.15.00.07

Not sure if it's the kernel or just the latest nightly, but I'm loosing my data connection quite often. Otherwise, its running great.

My built in wifi tethering isn't working either....sad day. I was loving how fast my phone charged

New version, number. 11 is online, testing now.

I haven't had any problems with this kernel yet even on wifi. I have also noticed decent battery life.

Funny, I'm running the test2 on Ruby as well. Been rock stable for 4hours. Practically a record for my phone on Ruby. Hope it makes it through the night.

Using the "test2" kernel.
Built in tethering works for me.
I'm running the 9/27 nightly.
No other issues so far.
P.S. I would love if internal memory was mounted properly in Windows.

Does anyone know if this new kernel is underclocked?

Another question would be, does anyone know if test kernel #1 or #2 is the test kernel in rom manager?

showing up as a 245-998mhz one with compcache optional... Not that I put much credence in quadrant scores, but I'm pulling over a 1300 on that. So plenty quick.

Also does anyone know if its undervolted?

#2 is running at default clock.
So far looking good on test#2 for me (9.26 nightly). I just had a meeting in a location where the phone has frozen up nearly every time I was running CM 6.02 or any previous build and it worked fine. If I make it out to lunch, then back home later today without a freeze I think we may have a winner. Or at least I'll have a winner...

I grabbed the test kernel on friday night via the ROM manager, am I running the latest test, or is there a new one with the same name? In other words do I have to redo it to get the test #2 I am seeing comments about?

I am running test2 and my only issue is with wifi cutting out and erroring out when running things like streaming media in the background, but no reboots. Tt just cuts out the wifi, and resumes relatively well upon turning the screen back on. For some reason the screen being off sets off a timer that cuts out the wifi after a while. I've tested this with both Pandora and Slacker. No cut outs when running over 1x CDMA (3G doesn't work in my office) except when my signal becomes nonexistant.

Unstable Wifi Connection on CM7

I'm having issues with the wifi connection having to be reset every few minutes when used. It seems to outright lose signal and can't even scan for networks until a reset. I'm on CM7 stable, using the latest OC kernel by Dalingrin. Anyone experiencing similar?

I have a similar issue.
From time to time (something like every 5 min), the connection seems ok (in the wifi pannel, it is stated as connected), but I can't access anything anymore by wifi. I have to disconnect and reconnect to my wifi router in order to make it work.
(I also use the last stable CM7... And apart from that, it's gorgeous ! )

So I'm indeed not alone in seeing this... interesting. Thanks for letting me know. As well, I agree, everything aside from the wifi works great and the tablet tweaks incorporated are nothing short of brilliant.

Mine is table with CM7 final and with Philmod 6, both with the 03/31 and 04/04 kernels.

same here - cm7 stable + 4/4 OC
just loaded up nightly 39 + 4/14/11A OC to try that combo

Is this not the same issue all over about AES? Check your router, if it's WPA2 it's AES, if it's WPA it could be AES.
CM7 and some routers have issues when AES is used, try to disable it.

installed nightly 39 + oc 4/14a no wifi issues so far

You mind Starring this issue on the Cyanogen tracker? Make sure you put all the relevant information as well as your Router HW and FW. Thanks!

I posted my remarks in a comment on the tracker.
But I'm afraid I don't know what you meant by "my Router HW and FW" ?

Can anyone else comment on this? I might just go down this route, but I'm wondering if there a few more who did similar and are seeing no wifi issue as a result.
Also, I'm surprised to see a CM7 final release with a wifi issue such as this. If it indeed is related to encryption (AES vs TKIP), that's further perplexing. While I could go about changing the settings for my router, I can't go about doing so for many others - particularly in public. As well, if I'm to tether from my N1, I'm going to do it with a password, meaning I'm to do it with AES as there isn't much choice built in.
I hate to say this as I'm impressed with the amount of work that went into (and normally always goes into) CM, but I figure it has to be said. To be fair, I'm not sure how widespread this issue may be (does it affect the version of CM7 on tablets, only?) but I'm surprised it can exist in a version of cm7 considered stable.

I'll try 39 etc but I suspect if they made changes in that regard they would have said to retest in that logged bug.
As far as I know, I've heard reports this happens on some phones as well, not just tablets, not just the NC.
And it doesn't affect most people, in fact I'll bet it affects a minority of folks. If it affected everyone I'm sure CM7 wouldn't have released that way of course.
And yeah I'm with you, I _do not_ want to use my N1 tethered with Open encryption, but not much I can do until this is fixed.

Did you try 39 out? This issue is MIGHTY annoying for me as it is kind of hard getting a company with 39 000 employees to back away from AES on the WLAN..
Also going away from AES at home means that I cannot have my access point using 300 Mbit 802.11N which also is a real bummer.
I found this at the CM7 bugtracker, look at the final few posts there is a wifi-driver to try out.
http://code.google.com/p/cyanogenmod/issues/detail?id=3314
Also noticed there was a complete guide about pushing the file here: http://forum.xda-developers.com/showpost.php?p=11974146&postcount=22

So if CM7 on my phone works fine on wifi, that means a NC should work the same more or less, correct?

I guess you didn't notice who posted in that bug, and posted tiwlan_drv.ko in the bug?
Anywho, for me it did help my own and work AP's, but it's still broken tethering to my phone. So it seems better but not perfect, give it a try. Just make a copy of the original tiwlan_drv.ko and push the single file from that zip up in its place and reboot.

CM7 Wifi Needs to be restarted every 3mb

Ok this is not your typical "my wifi wont connect issue"
i have tried a fios router, linksys cisco router w/ dd-wrt and linksys router stock. I first had cm7 on sd and assumed that was the issue so I flashed to emmc. It works great but the wifi stalls after about 3mb of transfer (or a couple of minutes of light usage) and i have to restart wifi with the power widget and it starts working again. EDIT: droid x and moto bravo work perfectly with these routers at the same time of the issue.
I already disabled wifi sleep policy.
I am using CM7 stable installed to emmc. its works fantastic otherwise but this is making it completely ususable for me. I dont think its a bad wifi chip since wifi was solid with HC on sd and seemed fine with stock nook 1.1.0
if i try to install an app it dies 75% through, if i try to play a youtube video it buffers 75% and then dies. it seems anything more than a simple web page lookup kills the wifi stack.
I havent had time yet to really dive in (been porting CWM to the motorola bravo in most my spare time) but hoping there is a simple fix out there, maybe i need to switch to dalgrin's kernel? but it also mentioned wifi issues and seems 2 weeks older than the kerenl supplied w/ cm7 but i am not sure.
This makes the nook completely unusable. Id rather not flash something else, it seems other people are having success w/ cm7 so I would like to work this out.
any ideeas? thanks

that sounds like possibly defective hardware honestly.... But you say it was fine on other ROMs so I dunno. I have had fewer problems on CM7 than Froyo myself. In fact CM7 has been solid with wifi. I wander around a lot with my NC and use many access points.

Do you have a logcat dump per chance?
If nothing is in the log, what is output of dmesg? Anything there that might suggest what's going on?
Also you might try checking out the command line program "wpa_cli". See if it helps you narrow down the issue. You can turn on additional debugging there.
Or, if you know how to rebuild your uRamdisk, appending "-DD" to the wpa_supplicant line in init.encore.rc would also give you more info in logcat...
One last thought-- if you are using dalingrins oc kernel, he took out a lot of debugging stuff (for speed), so if you want more info, revert to cm's stock...

I hope its no hardware, its over 30 days old, i didnt get the extended warranty and I have a ghost armor on the screen
good to know your wifi is solid w/ cm7 and its not a general cm7 wifi issue. what encryption are you using?

Hello-
Its very unlikely to be Nook issue. I have had this issue with laptops and its always the ISP or the router.
Hope this helps.
Cheers,

I had almost identical symptoms. I disabled encryption on my router and have had zero issues since.

Check out my thread on wifi http://forum.xda-developers.com/showthread.php?t=959823&highlight=dummies
My guess is that it's something in the wifi chip driver ir the wifi software stack. I have the identical symptom where on youtube, it stops after a few mb of download. (Note for mine it was stock NC with auto-nooter 3.0.0) The fix for mine was to set the router to 802.11 g only. So try this test:
1. set the router to 802.11 g only
2. turn off encryption
Let us know what happens.

I'm thinking that these devices have varying wifi quality.
My Nook Color is rock solid with wireless, regardless of encryption. WPA2 AES works as well as no encryption. I use my NC regularly with about 5 different access points around town. I'm using Dalingrin's 1100 MHz kernel with CM7 stable.
On the other hand I have a Motorola Droid that barely works unless I either turn off encryption or go to 802.11b! Those Droids were rather notorious for poor wifi. It does the same thing the OP mentioned - it stops transferring after a few megabytes although it says it's still connected. The wireless must be disabled and re-enabled.

It's AES, plain and simple. Turn it off on your router. if you're using WPA2, set it to WPA.
Your problems will go away. Now go to this thread, star it, and add your info please: http://code.google.com/p/cyanogenmod/issues/detail?id=3314

Lol I was 99% sure of this. I had the same problem on 2.6.29 kernels on my dx. it magically went away on 2.6.32.
I am using AES, I was going to try to turn it off next, now I know
thanks.
Fattire, thanks, I checked wpa_cli and it just fails to find anything and the scans fail once the issue happens.
The one thing all those routers I tried had in common was AES, its the only thing I really trust. I guess i will have to setup a stub network and seperate AP for the nook color
thanks!

After setting the AP to WPA2/WPA Mode the Nook's wifi is working perfectly under CM7 (except for needing to be restarted after the screen is off when sleep policy is on but i beleive this is a common documented issue)
thanks!
I posted on the cm7 thread and hopefully they will get this fixed asap.

CM7 latest nightly Wifi issues

I just flashed the latest nightly(#85) over 7.0.3 stable. It flashed with no issues, but I noticed that Wifi is cycling on and off. I tried nightlies #83 and #84 and all do the same thing. I restore back to the latest stable ROM and it doesn't have any issues. Any ideas?

I'm having some problems as well with 87. It was running for a while, with weak signals... and now it just stopped working altogether. I tried a hard reboot and still the same. Tried to fix permissions and reboot again, still nada. It's like it's not detecting any network at all.

I never get why so many people have problems and so many others don't.
I was having issues on 7.0.3 but since I've went to N87, I've had little if any problems.

This makes me hesitate- I "was" going to make the jump from stable to nightly's--not sure at this point!

I also cannot get the wifi to stay on. I prob will go back to stable with OC but does anyone know if 7.0.3 has the sleep of death fixed?

Try it, just about all my wifi issues disappeared with N87.

It does not.

ive had no wifi issues with n87

My wifi issues are this:
Noname Generic wifi router at work using WEP: Rocksolid
Trendnet Cheap wifi router at home using WEP: Rocksolid
New Belkin wifi router at home using WPA: dropped wifi every few minutes.
So I guess it depends on how much security and speed you want from your router.

[Q] wifi error after new kernel

I have a v20l and i flashed the hp kernel but now wifi gives an error
I flashed the hp for v20l from spica1234's thread
Can this problem be solved?
thanks

Reboot after attempting to turn on wifi it should work flawless then. I had this from time to time also with other kernels.

what kernel do you use? RC9 or SR2? in my exprience SR2 gave me wifi error ater 1 day hours of usage. and juice defender is also make it problems with HP kernel
right now i'm using RC9 and already 1 day 6 hours and still no error on wifi yet will let you know the progress. and i set the wilress sleep policy when screen turns off

I was using rc 9,
But now the problem is solved, first i flashed performance pack 7 and then rc 9 again and it helped.
But still dont no what was causing the problem

ow, so you have already flashed the RC9 kernel. maybe because the wifi module still use v10e on sr2, in RC9 used v20L sources
but in rc9 tun.ko can't smooth working like in sr2

Hi
I see a lot of people complaining about wifi problems
Even thought it was a faulty device, but it does not look that way
How to really fix the issue ?
Its not a cheap / low end device to just keep rebooting everytime as a workaround
For ex, i put the phone in airplane mode, just to check, then turn off airplane
and wifi dies...
Or if i disable wifi, and try to enable again, same problems
Here i use a tplink WR1043ND, has good signal, and i use with b/g/n - WPA-PSK/WPA2-PSK with AES sec key.
If i change to another encryption, its gonna work better ?
I bought this device last week, and if i cant use wifi security and have problems like that, i will be forced to return to the seller
tks
