OK, I have a somewhat-convoluted but reliable way to reproduce this, and it seems to be peripherally related to ondemand (see below):

1) Flash the 0616 test kernel

2) Reboot

3) Set governor to ondemand

4) Set wifi to always on (haven't had a SOD from this so far, thank God!)

5) Set the display timeout to 1 minute

6) Start up Pandora and let it begin streaming

7) Hit the n/home button

8) Let it sit on the home screen until the display shuts off

9) Wait patiently another 2-3 minutes and observe in wonder as the wifi goes away and the sound stops

10) Verify wifi is toast by trying to open the Market (without attempting to manually toggle wifi off/on) and see that despite the pretty green icon you have no connectivity

Lather, rinse, repeat with conservative in step 3 and see that it will not fail/disconnect. I did my testing on n103.

Rodney

UPDATE: OK, so it happens on conservative (with the OC kernel) as well, but seems to take a lot longer to trigger (it went for more than 15 minutes before wifi died). Will retest all with stock.

UPDATE 2: With n103 stock and ondemand (and wifi again set to always on), you lose wifi the _instant_ the screen shuts off...you can literally watch it happen in perfect synchronicity (at least the OC kernel had the good graces to wait a minute or two to kill off wifi). Testing stock conservative now.

UPDATE 3: n103 stock and conservative stubbornly refuses to fail after 40+ minutes. It would seem that's the only combination thus far that hasn't failed. This seems to suggest that a) there's a definite issue with ondemand, and b) there's something else about the OC kernel outside of the scheduler that causes a behaviorally similar problem.

UPDATE 4: stock+conservative finally died as well, more than two hours later. The difference is that the wifi icon actually turned white instead of remaining green, so at least you know you have no connectivity. Cycling wifi made it come back, but it's still a mystery to me why we lose it anyway, and why it seems sensitive to both kernel and scheduler (obviously that means it's not a DHCP thing).

Samething here, wifi drops especialy when downloading large files.

Using OC kernel with 102 NL.
[Nook Color Android Development] rhester72:
Testing completed, see all updates at the bottom of the post 2 above this one.

Stock kernel + conservative appears to be the only way to fly at the moment for full stability.

[Nook Color Android Development] mr_fosi:
My wifi has suddenly started acting hinky.

I haven't seen any descriptions of my problem and this seemed like the place to bring it up so, here it is.

I have had problems seeing the WRT54G WEP-secured network at my work for some time. It has been a problem since the n86+ releases. The AP was active, other device's connections were fine, but the NC wouldn't see it. If I left it on with the wifi connected, after 5-15 min it often would suddenly see the WEP and connect to it. Once connected it would keep it for as long as I left it.

I am currently on EMMC n105 with the 06/13 kernel and the ONDEMAND gov, but the behavior I am about to describe was also in force when I use the stock n105 and n102 kernels as well.

Not having installed anything new, my formerly rock solid wifi will now not connect to APs (any APs!) about 80% of the time.

- It doesn't matter if an AP is secured or not, doesn't matter if it's remembered or not.

- I will turn the wifi on in wireless settings and I will watch for my list of remembered APs to pop up. 50% of the time, no list pops up, though it says it's scanning. It will never pop up, nor connect to anything if I let it go.

- If I cycle the wifi sometimes the remembered AP list shows up but often it will not list any in range even though several of them are well within range.

- If I cycle the wifi several times while crossing my fingers and standing on my head while singing Kumbaya, sometimes the list of remembered APs will pop up along with some non-remembered ones and I am able to connect to an AP.

I've wiped caches and flashed new releases and the behavior has been consistent.
[Nook Color Android Development] rhester72:
If you do a wifi scan and see nothing but remembered devices, try removing _all_ remembered devices (yeah, I know, it's a PITA), then toggle wifi off and back on.

This is proving to be as hard to get to the bottom of as the SOD. :P

On a positive note, my reports above seem to be faulty, because it appears Pandora is _not_ the best test vehicle for connectivity. =) A simple terminal ping test exonerated the kernel and scheduler - I've been rocking solid WPA2/AES connectivity to the AP I've had the worst experience with for more than 2 hours (a new record!).

Now, as for why Pandora suddenly decides to crap itself and take wifi with it, that's another matter...

Rodney
[Nook Color Android Development] rhester72:
Oh, I forgot to mention...if you run a constant ping in the background (or presumably any other two-way communication with a transmit period less than the screen timeout), Pandora will seemingly run forever without problems or disconnects. That kinda suggests that wifi almost _needs_ outbound traffic periodically to prevent a problem.

Come to think of it - some modern PCI NICs will put themselves into hybrid sleep if there are no outbound packets for X minutes. Is it possible that (some of) the wifi disconnects are the radio itself going to sleep, independent of the CPU/OS?

Rodney
[Nook Color Android Development] rhester72:
One more data point...

Eventually, Pandora crapped out even with the background ping running. That's not the interesting part.

The interesting part is the following from pings after the wifi dropped (though the icon still shows green):

ping: sendmsg: No buffer space available

No buffer space available? Hrm...

Rodney
[Nook Color Android Development] quai:
I was having the problem of being connected and wifi would stop working after about 2 minutes. The connection never dropped I just had no internet. I would have to disable then enable the wifi every 2 minutes. Now none of this started happening till I changed my router to a netgear. I went in to my settings and noticed that the ip address was different from what my old d-link router was, which I had to change on that due to a conflict with my dsl modem. So I changed my new netgear router to the same ip as the old d-link and fixed my issue completely. No wifi disconnects or problems whatsoever! Something to try or consider.
[Nook Color Android Development] EnTg888:
It appears that Nightly 106 solved this problem, probably due to the wifi driver update. it's been going good for at least an hour or so now, whereas before it wouldn't last more than 2 min before dying.
[Nook Color Android Development] dalingrin:
I need feedback on the latest nightly. I'm not sure if I've fixed all wifi issues or not with the latest update. I hope I fixed at least some of the issues people are having.

Please test only with the stock kernel for now.
[Nook Color Android Development] mr_fosi:
I've d/l it, will soon flash it and will post back with (hopefully useful) info.
[Nook Color Android Development] dalingrin:
FYI, I've updated the OC kernel with the same wifi module so you can test with it as well.
[Nook Color Android Development] :
Stock kernel nightly 106. Was able to download nightly 107 from rom manager on my nook. This is the first time I have ever been able to do this as internet connectivity would always die in the middle of a big download like this (and wifi icon would still be there)

Thanks!
[Nook Color Android Development] christoophat:
latest nightly/kernel

Seems to have improved things a bit, though I still find Netflix

almost impossible to get to load up any movie for me. Able to login & see my movie offerings, just nothing will play, always get the error message

Pandora works a bit better , though it stopped after 15 minutes, with "loading" spinning for a while till I stopped it. Market seems to load up fast & work, so I guess I'm using that as a yardstick to measure that some progress in this wifi issue is improved. If this wifi bug gets squashed, I call CM7 "near perfection"
[Nook Color Android Development] Lyphen:

[Nook Color Android Development] christoophat:
Seems that I was a bit premature with initial findings. It's MUCH more steady/stable than before, I had TuneIt radio w/ Soma FM playing for several hours till I turned it off, and was able to watch Netflix uninterrupted .

[Nook Color Android Development] breebauer:
Just wanted to chime in here- maybe it will help someone...

A few days ago, I switched over to cable internet and had to reset my router (Netgear N300)

Before that, I had WEP security settings and no wifi problems, using any cm7 nightly with any kernel. I'm using cm7 #111 and 6/18 kernel now.

After resetting the router and going through the network security setup again, I decided to just go with the recommended setting: WPA-PSK [TKIP] + WPA2-PSK [AES]

Everything else in my house could connect except my nook. I tried renaming the device, forgetting all connections, turning off network location, etc. and still couldn't connect. (It seemed to connect, but immediately got bumped/dropped, and cycled like that a few tines before giving up.)

When I set up a guest network on the same router, but this time used WPA-PSK [TKIP] security, it connected right away.

I know close to nothing about wireless networking, but figured I'd mention it. Hopefully that helps....

Go to Settings>Wireless & networks>Wi-Fi Settings then press menu and go to Advanced. The options are there under Wi-Fi Sleep Policy.

By the way, I use Wireless Tether on my Droid a lot for internet access on my NC when I don't have a wifi connection. Yesterday, I went into the wifi loop of death, where it recognized Wifi Tether, but wouldn't connect and kept scanning and getting IP address and disconnecting. I tried forgetting the Wireless Tether on my NC and inputting the authentication data again, reflashing the Dalingrin 6/18 kernel, going from nightly 115 to 116 and flashing the kernel again, and none of it worked. Finally, I wiped data from the Wireless Tether apk on my Droid and then set up my wifi encryption and access controls again manually, and the NC connected again right away. I'm just putting this out there in case it helps anyone with a similar issue.

Ah..I see it now,THANKS!!
[Nook Color Android Development] rhester72:
I have been able to somewhat reproduce the "suddenly your wifi goes away" problem with RC1 and the 6/18 kernel (doubt the latter makes any difference). All you have to do is load it up with enough different SSIDs (mine went nuts when I hit 9), and sooner or later it will simply stop connecting or scanning at all (i.e. it won't "see" any live SSIDs at all). Usual fix of deleting a few of them and/or the one you're currently trying to connect to fixes the problem, but it sucks that we seem to have an unintended upper limit on the number of SSIDs we can track.

Lemme know what you guys think, or if this is a good price.

I'm getting a Sensation for full retail and wanted to sell my G2 possibly here on xda. I'm not asking for buyers, but wanted to know if this was a good deal, or if I could even RAISE the price possibly.

I'm asking 260 USD for the following-

A mint 9/10 TMOUS G2, rooted. I say its not a 10 only for the fact of it not being FLAWLESS because There are a few scuffs on the battery door itself, and SMALL chips on the bottom corners of the phone of the matte finish. Been in an otterbox since the day I received it. Has a screen protector installed, but have an extra zagg shield unopened that I can include.

I have all the original packing including the charger, box, etc. I would include the otterbox, and 2 other black cases and of course the Zagg shield.

What do you guys think?
[G2 and Desire Z Q&A, Help & Troubleshooting] redpoint73:
There are a few G2's on eBay currently at $150-170 with a few hours left on the bids (they seem to be in good condition as well). Price may go up some in the last hour or 2, which is often the case (eBay sniping). But it seems like your asking price may be a bit high. I'd only put an added value of around $30 on the Zagg shield and cases, as I don't see a reason why a buyer would put much value on multiple cases.

[G2 and Desire Z Q&A, Help & Troubleshooting] Spastic909:
You got the G2 for upgrade price right? If so don't be greedy. If you got it for full price I still wouldn't understand that price. If there are chips on the phone big or small...

Craigslist used to be cool until greedy bastards started overcharging for everything
[G2 and Desire Z Q&A, Help & Troubleshooting] PatrickHuey:
I really appreciate the responses. Ill see what Craigslist will do me. I did pay upgrade price for the phone, but I guess I think people are always looking for a phone and not wanting to pay a huge amount for the phone. I just wanted to make sure I was gonna sell local in the DFW area. And if you know the area, there are tons of cities in north Texas.
[G2 and Desire Z Q&A, Help & Troubleshooting] redpoint73:
I think charging a fair market price if fine, even if its more than the 'upgrade price' (not sure what you paid for it). For one thing, T-Mob was offering the phone for free over Valentine's day. So does that mean in that case, you have to give the phone away for free? Of course not!

The other thing is, one of the benefits of buying from a 3rd party, is that you DON'T have to use up your upgrade. So this might alone is a reason for somebody to pay more than the upgrade price.

Yes, you need to ask a fair price. Since if you don't, nobody will buy the phone anyway.
[G2 and Desire Z Q&A, Help & Troubleshooting] PatrickHuey:
yeah I know what you mean. That's why I'm saying people WILL buy because they don't have an upgrade and want a phone. I think ill miss this phone for sure, but the sensation will do me justice. I did pay about 215 after taxes for this one when it waaaas an upgrade.

you need root access, see http://xdaforums.com/showthread.php?t=1103399 : [12.09.2011][CF-Root v4.1] KE2/7/8, KF1/2/3/4, KG1/2/3/5/6/7, KH1/3/4 - su+bb+CWM4

and some other good threads with more info about installing rooted kernels.

I had kernel version 2.6.35.7-I9100XWKF3-CL276555 on Android 2.3.3.

I installed Chainfire's CF-Root-SGS2_XW_CLK_KF3-v4.0-CWM4.zip .

I installed cifs.ko and slow-work.ko for 2.3.3 (cifs-for-GT-I9100.zip) in /mnt/sdcard/ but mounting -t cifs didn't work with cf-root.

Seeking desperately for a solution I noticed the "(for stock kernel)" from above.

So I installed the stock kernel for my phone from http://xdaforums.com/showthread.php?t=1075278 : I9100XWKF3_Kernel.exe. I still had root access but no longer CWM and busybox (no more ash shell).

Then cifs finally worked (I had to reboot a few times when after a while I could not mount my shares again).

There are others in the cifs.ko thread who say they are on a cf-root kernel and that cifs works with it, I guess because of android 2.3.4 or something else.

Make a writable directory where you want to mount your samba shares. insert the modules manually and issue a mount command or use cifsmanager: http://xdaforums.com/showthread.php?t=756158

There are insmod options to improve speed, like:

insmod /mnt/sdcard/cifs.ko CIFSMaxBufSize=130048 cifs_mic_rcv=1 cifs_max_pending=20 forcedirectio=1

and for mounting: directio,rsize=130048,iocharset=utf8

I am still not able to watch 1080p videos via cifs over wifi without stutter. Very annoying.
[Galaxy S II Q&A, Help & Troubleshooting] vatbier:
well 1080p mkv videos play fine with Dice Player without stutter and with subs but the stock video player is the only one that can output video with subtitles on hdmi output.

But the stock player refuses to show subtitles when I play mkv videos that are mounted with -cifs.

I still do not have a solution.
