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!
http://code.google.com/p/cyanogenmod/issues/detail?id=3314
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.
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?

You have 1 year manufacture warranty.
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,
mg
I had almost identical symptoms. I disabled encryption on my router and have had zero issues since.

the same thing was happening to me and it just seemed to stop one day.. i think it was after nightly 35 or 36

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.
Search function is currently unavailable, so apologies if this is a dupe...
Anyways, I'm currently running Rooted Stock 2.3.4 on my N1, and I've noticed that whenever I connect to my friend's DLink router (DIR-655, I think) the Wireless will work for some amount of time, but eventually it will stop working. And not just on my phone, either - the entire router stops working (at least for Wireless requests. Didn't have any wired devices connected to it). Thing is, last time I noticed it, it worked for quite a while - hour or two, maybe - then everything broke about 10 minutes after I received an email... At that point, the router needs to be rebooted, after which it continues working just fine.
The router is using WPA2 encryption, for what it's worth.
I've noticed this with previous versions of Android, so it's not a breaking change introduced with 2.3.4 or anything.
Unfortunately, I don't have an awful lot of Wireless routers to test with, and I haven't yet found an opportunity to test at home, so I'd be hard-pressed to say whether it's a router/D-Link problem, or if it's a device problem...
Has anyone else experienced this? Would flashing a custom ROM (e.g. CM7) fix this? Or would I need a new device? Any thoughts on what else I could do to debug this problem? As I said, this is a rooted device, with an unlocked bootloader and the latest version of Busybox installed.
I'm running 2.3.4 and haven't had this issue with this version or any previous ones.
I've had my phone disconnect from Google Services (the icons turn white instead of green), but the internet stays on and all other devices work just fine.
I have a Netgear router at home and a Linksys one at work and I'm connected to both the whole time I'm at either place.
Hmm... That's interesting.
I've never had Google Services disconnect, but I do have another issue with data randomly turning off. That's not a big deal, as I can just turn it actually off then back on again, and all is good.
Anyone else able to chime in with their experiences?
I have had this happen with cheap, crappy routers. Sometimes upgrading the router to DD-WRT helps, sometimes it doesn't. I had an ASUS this would happen to all the time, and an Airlink that this would happen to occasionally.
This doesn't ever happen to my Linksys WRT610N, and it never happened to an old ZyXEL X550.
I'm going to say, it's just a crappy router.
Thanks. Not really what I was hoping to hear, but that's life.
Did either bad router ever have this issue with other devices? One of the other folks living there has an iPad, and never has this issue, so I'm inclined to say it's at least partly my N1s fault. Also doesn't happen with any of the PCs connected to it.
Yeah, they actually did occasionally have issues with other devices. Hard to narrow it down because I have a ton of Wifi devices. The ASUS also seemed to go down based on time... after so long, it would just stop working properly. The Airlink seemed to get stuck based on demand and range. If I had my phone or laptop at the far end of the house and started using it a lot, it would get stuck. It was as if the router decided it was too much work to pump its signal that far and it would get tired.
Stock ROM on my N1 doesn't seem to allow it, but if you have a custom ROM, you might see if there is any way to set the Wifi to G-only. I had noticed on my old router that G wireless devices seemed less demanding for it.
Hi,
let me thank you for all the help you may give me.
The problem is i get stuck on obtaining ip address or the cell doesn't even try to connect automatically so i have to manually start the wifi connection to the network after turning on wifi.
The problem of my SGS not connecting automatically is rare, the first is not, it's actually quite often.
I looked through all the guides and sugestions but i couldn't find any permanent solution for this problem.
Note: I've used the AllShare app but sometimes even that doesn't work.
Thank you for all help
The same problem kept happening with me. Some of the fixes which I tried were
Change channel on router - didnt work for me
Use the allshare app first - worked
Set up a static ip in advanced settings - almost always worked
But I have found that I didnt have this problem with other routers, only mine, maybe because of a power problem with the router.
Many of baffling errors are usually caused by bad input power to devices.
Hope it helps
Thanks for the reply, the problem is that i use it alot on my university, where i can't do any changes to their router (or use static IP).
Also the AllShare app is indeed a fix, but only if used every time i think. I'll do some more testing, this problem is really annoying and that's a shame because it complicates the use of most of the smartphone capabilities.
So if anyone else as another solution i would be glad to hear it.
Also i'm on stock rom installed by my operator Vodafone (had the same problem on JPY).
Edit: After a very quick test, it seems that using Allshare once does work, but i had the impression that sometimes it would be needed more than once (even without rebooting). TY for the tip.
Update:
After some more tests i came to the conclusion that at home i need to use AllShare every time i want to connect to my network.
This seems to be a problem affecting several users of SGS, does anyone know the answer to this problem? Or at least an app that minimizes it?
It's quite bad and very frustrating. Thanks, for any and all help.
I had the same problem with stock Android 2.2.1 on 3 phones all Galaxy S. Dropping the packages on voip calling, internet was slow most of the time. I use a linksys wrt54g with dd-wrt, I never had problems with any other devices.
My problem was solved when I installed GingerReal. Also on Miui I didn't had any problems with the wifi connection.
Maybe is just the stock driver incompatibility with some devices.
Thanks for the reply,
I've only had bad experiences with flashing, last time i did everytime right and Odin just hanged, i almost had a serious problem in my hands.
Since this is probably the first and last good phone i'll ever have, i would really like not to kill it (also some people in my family would be very disappointed, it was a gift).
So any workaround? Sorry i'm so insistent but i think that are a lot more people interested in this. TY.
Even with the latest update as of May 2022, my new Tab A8 exhibits Wi-Fi stability issues not seen on the old Tab A7.
After leaving a connected tablet to sleep, Wi-Fi for some apps won't work and only a WiFi OFF + WiFi ON reset will restore connectivity.
Anyone else encountered this problem?
Same - it just won't stay on any network for long at all. It won't connect at all to my VirginMedia router saying 'couldn't get ip number'
Doesn't happen to me from what I've seen... Have Xfinity cable internet together with a Netgear router/modem.
Have you guys done all the system updates?
Yup, up to the latest from April. Tested on 2 devices and it's the same. Factory reset doesn't help.
I'm hoping that if not before, at least the Android 12 update will resolve this.
I just updated to Android 11 firmware update from last week - X200XXU1AVG1 - but the issue remains the same
On Build number RP1A.200720.012.X200XXU1AVC1, no updates I'm aware of. When this happens to me and I toggle wifi off and back on, no networks display. If I toggle airplane mode it they will appear again.
II'm in the USA, using an asus blue cave router.
What's everyone else using?
Anyone know what wifi chipset this tablet uses?
Got the update to Build number RP1A.200720.012.X200XXU1AVG1 it still occurs, and I'm also noticing bluetooth connection issues, both are cured by cycling airplane mode on and off.
Yeah... let's hope Android 12 includes fixes for this... really, the Tab A7 was a much better device with a nicer screen

I reported the issue via Samsung members app with a bunch of screenshots,
SM-X205 is now getting Android 12 but nothing available yet for SM-X200. Will probably take a couple more days
OK now SM-X200 also got the first Android 12 update and the results are... BAD! Still the same issue and I'm quite done with Samsung for now. Unbelievable that they do not test the basic functionality well enough. I expected some WiFi driver updates under the hood but it seems they are oblivious to the fact Tab A8 has issues.
Had the issue one time since the 15th it's not solved but less frequent at least
What I notice now is that the wifi will turn off randomly. If turned back on it reconnects but shortly thereafter bluetooth dies and cycling airplane mode is required
