After upgrading to JK4 via Kies I've noticed some strange Wi-Fi behaviour. It seems to manifest at different times and for no apparent reason, so I'm starting a thread to see if a) anyone else has this issue and b) if so, how does it manifest for them.
First manifestation: after turning on Wi-Fi through Notifications the text switched to "On" but the Wi-Fi symbol did not turn green. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was showing "Error". A reboot of the phone fixed it, temporarily.
Second manifestation: after turning on Wi-Fi through Notifications the text switched to "On" and the Wi-Fi symbol turned green, but it did not connect to my wireless network automatically like it should. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was rapidly switching from a "Turning on" state to "Turning off". It did this about 10-15 times in a few seconds then went to "Error". Turning on and off the Wi-Fi again solved this issue.
Every time I solve this it seems to come back within a 24 hour period. I didn't have this problem (from what I can see) on JK3. I factory reset before and after flashing to JK4, and I flashed JH2 back just to be on the safe side beforehand.
Let the discussion begin!

I quickly tried out after reading your post, and I did confirm your first issue happening, but only when I turn my Wi-Fi on and off really quickly. Also my phone didn't lock up as you described either. Basically, I could only make that issue to surface once I turn off the Wi-Fi, and then turn it back on as soon as my phone reports it is disconnected. When I go into Wi-Fi settings, it does say "Error" there, but if I check the "Wi-Fi" there again, it connects automatically.
I almost never use Wi-Fi because I get 6GB of data, but I can see this becoming a very annoying issue if you have to use Wi-Fi frequently.
Edit: Actually, I ran into a different issue just now. I kept on playing around with my Wi-Fi, and confirmed this happening: Wi-Fi text turns to "ON" but the icon doesn't turn green. When I go into settings, it says "Turning Wi-Fi On.." or something similar and is stuck there. I wasn't able to turn on nor off the Wi-Fi. Reboot fixed issue...for now I guess.
I have also had this issue but I believe it has to do with trying to turn on wireless when your preferred network has a very weak signal. When I'm next to my router, I can turn wi-fi on and off rapidly with no issues. I have only had the issue in my room which has a much weaker signal.

i was having problems with my wifi today...i wasnt able to pickup any wifi signals and i couldnt manually turn the wifi on either...i got a few force closes on some apps and decided to reboot the phone, hopefully sovling the problem...instead i got stuck in the boot loop at the i9000m logo and now my internal sd card is done....hopefully i can return this pos at bell(im on rogers) and do a hup through rogers for the iphone4...at least thats a stable device.

I've never tested right beside the router, but my room is next to the room which has the router so I would think I'd have a fairly strong signal.
Interesting, though...

I tested my Wi-Fi pretty much right beside my router as well...like less than 3 feet away. My phone was reporting it was seeing an "excellent" signal.

I find my wifi on my phone to be pretty solid.
I have an occasional issue where it does not see my wifi router at work, but all I do is turn it off / on and off she does. Just happens with the work router. Never had an issue with my linksys at home.
I've experience this issue with JH2 and it was caused by a change to fast in the settings. Just give your phone some time to connect and get identified on the network before you turn it off ans don't torn it on right after you disconnect it and you should be fine.
Been having the same issues since upgrading to JK4. Wifi gets stuck in "enabling" state occasionally when it try to turn it on. Sometimes I have to go as far as restarting the phone to get it to work again. Not a huge deal but still a nuisance.
I have seen both of these situations occur once after applying JK3 from Odin. It was shortly after booting it up for the first time including the "ERROR" text. I attributed it to a one-time glitch and it has not come back since. When I am home I force WiFi on and leave it in that state until I leave the house for work the following day so I am not constantly messing with the settings.
I get a similar issue butt only when activating my mobile AP.

I've been having a similar issue with my wifi since upgrading to JK4. I've gotten the "error" message on enabling wifi, but as others have mentioned it may be because I'm re-enabling it too quickly after turning it off. However, in one instance yesterday I tried re-enabling it several times after turning it off via the control widget and was ultimately forced to reboot before it worked again. Also, this morning I found that after leaving home and coming to work, I was still only seeing the wifi hotspots near my apartment rather than the ones in my new location (one of which I have saved and automatically connect to). I had to reset the wifi to find the local hotspots. Other than these wifi issues, I'm really loving JK4 so I just hope they get sorted out.
The problem is that Background Data and Sync ignore the wi-fi policy meaning that the settings to disable wi-fi don't actually disable wi-fi, they just block applications from using wi-fi. The OS can still use it and it still drains power.
That basically means you can never disable wi-fi unless you go in and change multiple settings. The wi-fi policy when the screen is off is useless. Any toggle wi-fi widget you put on the page don't work.
Manually refreshing gmail shows 'no connection' - browser wont connect. But the OS can still get your email and download attachments. Relegating any wi-fi policy to a 'user stop function', not a 'data stop function'.
I have a toggle wi-fi widget on my home screen. I have wi-fi toggled off (also shows as off in settings) I *just* saw the widget flick on for a second, then flick back off. That's the Background data/ sync kicking in right there and that's my whole point.
Another point - if you have disabled wi-fi then turn it back on, it should be looking for the router and getting an IP address. It doesn't do that. When you turn it back on all it does is enable applications to connect. Meaning, when you disable it (via settings>disable wi-fi or disable wi-fi policy) all it does is make the software think you're not connected. It doesn't actually disconnect from the router.
It still shows in your routers wireless list (which it shouldn't if it's disconnected) and ping test will fail because it will refuse any incoming/outgoing requests that aren't from the OS (background data / sync)
If you wait for the background data/sync to connect, you can then ping your tablet and it will work. A security issue as far as I'm concerned.
UPDATE | May 05
An update. I can confirm that the wi-fi will never turn off for me. I have toggled it off and put it in airplane mode and I will still get email notifications.
Under battery power it even still shows wi-fi as taking 4% even though by all settings it is off.
The gmail application shows 'no connection'. If i refresh it, nothing happens. If i turn the screen off, eventually it will sync/connect and I will get email - even though I also have the wi-fi set to off when the screen is off.
So to sum-up - wi-fi never turns off. Ever.
You can help by testing!
Disable wi-fi
Set the policy for wi-fi to disable when screen is off
Go to home screen
Turn off the screen
From another location, send yourself an email
Wait for notification on your tablet or wait for about 5 minutes
Turn on your tablet, email should be waiting for you.
UPDATE | 12:15pm
On the phone with acer support and they confirmed this is the case. They started to explain about Background data and Sync and I stopped them right there. This isn't a settings issue, this is an OS/Hardware issue.
Going to the next tier.
UPDATE | 12:30pm
Everything is confirmed with tier 2 and for what it's worth, it'll be pushed further down the chain and looked into.
I had to clarify with them that the issue was with the OS/Hardware and it's not software. If the wi-fi is disabled and I can go into gmail and it show 'no connection' and i hit refresh and it wont get email, then open the browser and it tells me I'm not connected, then the software thinks the wi-fi is off.
The problem is that the wi-fi isn't off as far as the OS is concerned. It is still draining power and Background data/ Sync are still able to connect (and/or override your settings). This shouldn't be the case. The wi-fi setting should superseed all other settings. If i set the wi-fi to off, it should be off for everything and not be draining power. To me this means that the disable wi-fi setting doesn't actually disable the wi-fi, it just locks out software from using it... which is *not* disabling it.
Same issue here, have to get a widget to turn of the wifi. How can they oversee such simple things?
Also sometimes the power button just randomly lights up when its in sleep mode, it's a small light but very anoying if it's dark in the room (e.a on your bed stand).
Okay - Good to hear it's not just me then. But not so good in general.
If you're reading this thread, try it out. Set the wi-fi to disabled when the screen is off then email yourself from another computer and wait for the notification on your tablet. Or get a friend to email you a minute or so after you've turned your screen off (with wi-fi disabled on screen off)
You can reset the policy after.
If you get the notification then your wifi didn't disable while the screen is off like the setting is supposed to do.
mine is NOT giving me issues, but I have found that it can take up to 10 minutes for the wifi to go off. I just used ping to test it. In some cases it took a while but did turn off. My battery doesn't really go down at all when in standby with wifi off when screen off.

I've set the wi-fi to disable itself when the screen goes off but unless I disable sync and background data, the wi-fi still stays on when the screen is off and I can hear my email/IM notifications still.
Anyone else have this issue?
I mean, I think it's an issue. If you set the policy to disable wi-fi when the screen is off in the OS it should override any apps - I shouldn't THEN have to go and disable sync and background data as well otherwise whats the point?

Hi, I just ran these tests and unfortunately I can't reproduce your results.
When I disable wifi, I don't have any data connection.
As for wifi sleep, I don't know if it's a bug or intentional but it seems to put wifi into an extremely low power mode, but not necessarily disable it or turn it off when using the sleep policy.
As someone mentioned somewhere in this thread, it looks like wifi has some sort of 'cooldown' period until it turns the chip and process off completely.
I have used Wifi sleep and played Pandora and had Pandora play for hours until it finally disconnected.
The problem is that Background Data and Sync ignore the wi-fi policy meaning that the settings to disable wi-fi don't actually disable wi-fi, they just block applications from using wi-fi. The OS can still use it and it still drains power.
That basically means you can never disable wi-fi unless you go in and change multiple settings. The wi-fi policy when the screen is off is useless. Any toggle wi-fi widget you put on the page don't work.

HI, i had no problem with Wifi. Since last time I got to the hostel and have a weak access point I have a bug with Wifi : when I activate it, it says "connecting... ". But nothing happens, it doesn't list access point around me too.
I found a way to make it work: I uncheck Wifi, check airplane mode then check wifi again. It works but I have to do it every each boot or wifi deactivation..
Is there a parameters or cache file stocking the weak ap I was trying to connect when the bug appears at first?
Thank you
Problem not solved but changer: now it work but wifi is never activated at startup.. can't force it to auto activate. Strange...
Anyone else have this problem? I just started having it, first on Phiremod 6 and now just updated to 6.3 hoping for a fix, but no dice.
I have sent back 2 nooks to BN for exchange because of this issue. I didn't know doing the airplane mode thing would temporarily fix the issue. I even did the 8 hard reset and restore and the nook would get stuck on finding wifi window - turning on wifi but nothing would happen. My nook was manualnooted 1.2. Strange?
I'm on nightly-87, Dal's 1.2GHz OC Kernel 5/23, and I'm experiencing something very similar. I went from 7.0.2 to N87 without a hitch, but I immediately started to see the WiFi icon go gray and lose it's connection. I was forced to restart WiFi as a remedy. As of today I'm getting something closer to what you're talking about; when WiFi turns on, the nook will infinity cycle through: disconnected->connecting->disconnecting->scanning. I've wiped Cache, Delvik-cache many times to no avail. Also tried re-flashing N87 and the OC Kernel, which did not work. I'm still not able to connect to my home network(netgear, WPA). But, after enabling/disabling airplane mode, I was able to connect to my LG vortex and obtain the interbuttz.
The last time I did a fresh install was around N20 something. As far as possible causes to this erratic and ethereal bug, my money is on certain update paths for both the OS and Kernel having different remnants. Example: with 87 different experimental OS installs and, to a lesser degree, the three different stable OS installs. There are technically !90 different upgrade paths. Compounded by being paralleled by kernel installs, but I believe when a kernel is updated the former is completely replaced instead of merged. I'm not calling out the Dev's, it would be nearly impossible to foresee and head-off all of the permutations of merging 87+ releases.
I'm no expert, just my two-cents. I'm not really concerned about this as a long term bug. There are fine people hard at work, and unfortunately have far more pressing issues to contend with. It's a sad reality that community driven projects, notably the nook Color, rarely reach maturity or complete/efficient hardware-software integration before the allure and newness of a product wares off.
As a consumer of .rockbox, a Linux based OS for G5.5 ipods and below, Of which I've been using for years and years. And, I would say it's just now becoming 'perfect', even with it's lack of support for many peripheral devices. I'm long term with my gadgets.
I'm rambling now.
Hope this helps to narrow down symptoms and possible causes.
It seems that my problem is a known issue of cm7 (when you click airplane it stay on forever but the checkbox remains unchecked). Try a tool from market that shown me the airplane mode and unchecked it from here. Since I didn't reboot from that test I don't know if it's solved for now.
my NC on CM7 just stopped connecting too
I turned on my NC this morning and my WiFi no longer works either.
All of my hotspots say 'not in range'.
I tried all of the tools I have to turn off 'airplane' mode (just in case it was on)
but, nothing seems to get me 'out of the mode.
What can I try next?
Wifi miraculously auto-fixed itself, and then broke itself again

While researching potential solutions... CM7 auto-fixed itself after about 15 minutes.
I didn't touch it.
All of a sudden I heard the Gmail tool beep at me with new messages and the market with a few apps updates that were available.
Now it seems to be working fine.
I spoke too soon, I just powered off and on again to see if the problem was fixed
permanently, and its not... its back to the 'not working' state.
(I hate when that happens, because I don't know what caused it, and I don't know what fixed it!)
This happened (WiFi not hearing any APs) to me a few times with nightly 87, but hasn't happened since I upgraded to n94.

SAME! Bump.
Same issue.....latest nightly on VG SDcard solution. Never had a problem until recently. Was runnning 7.03(flawlessly) then suddenly started experiencing the issue, flashed the latest nightly (113)...worked for a bit, rebooted and now nada..... just sits at connecting..... then goes to disconnected. Cycles every couple of minutes.....
Any suggestions on what to look at?
**** Note ; WIFI works fine when I boot to EMMC (Nook 1.2) . So I do not believe this to be a hardware problem.
I was just looking for this issue also.
I was doing great with nightlies and the OC 6/18 kernal, this morning I updated to the Nightly 114, and I received no wifi connection on booting up.
So I did all the normal things (1. turn on/off the airplane mode - No change, 2. fixed permissions - no change, 3. restarted multiple time (aft all the prior changes) - no change) Ok I thought, I will go back to my previous nights backup (Nightly 113). But I still get no wifi. The widget says trying to connect, but none of my networks are showing up within range. I run wifi analyzer and I see NO networks (normally I would see about 5 to 7 of them).
So I begin stepping back, I reinstall the Nightly 113, with No OC, and while the wifi is off on bootup, once I 'turn it on' now I see my networks.
I'm cooking with gas now, so I install the OC 6/18 - No Wifi
So I install the OC 6/13 - Still no Wifi
Both times, the Nook boots up with the wifi 'off' so I turn it on, but no connection or sensitivity.
I again reflash the Nightly 113 only and while it again boots up with wifi 'off', I am able to turn it on and it actually sees my networks.
So strange, I am stuck without my OC kernal, but as least the nook works again.
Does anyone have an idea why this is happening to people?
Thanks

The issue in the OP isn't related to the one you're talking about. Try deleting one or more of your remembered wifi access points with wifi on. Let it rescan and, if it's not some other issue, it should find your access points and connect.
Suffering this same issue as well on my Nook Color. I believe the problem lies under /data, and here's why. First, I made a backup of /data, and then wiped everything:
* I restored my device to factory 1.2: Wifi works
* I flashed CM7 nightly 113: Wifi works
* I flashed dalingrin's OC'd 6/18 kernel: Wifi works
* I restored /data from my backup: Wifi is stuck at "Connecting..."
I thought it might have something to do with the settings.db file under /data/data/com.android.providers.settings/databases/, but when I deleted that file and rebooted, it made no difference with the Wifi problem.
Something under /data might have a problem with the latest CM7 builds, but I couldn't say what exactly. I'm not an expert at this stuff, so I can only share what I've observed and tried for myself.
Hi. I have the same problems with Wifi since this morning. Is there any other solution then turning on and off airplane mode? thx
Formatted /system and /cache, and wiped the Dalvick cache, then flashed only CM7 nightly 143.
The problem still exists. Wifi is stuck at "Connecting..." Has anyone found a solution to this? It's obviously something to do with a setting/file under /data, because if I format /data, Wifi works like normal. But when I restore my backed up /data, Wifi is stuck at "Connecting..."
I think I found a solution. This worked for me, so I hope it works for others.
Shortly after writing my previous post above, I decided to play around with my NookColor, to see if I could get the Wifi to work normally again. Here's what I did, which fixed the "stuck at connecting" problem for me:
1) Go to Settings > Wireless & networks > Wi-Fi settings
2) Check to enable Wi-Fi, if it's not already enabled
3) Click every wireless network in your list and choose "Forget"
4) Make sure every wireless network is forgotten
5) Check to disable Wi-Fi
6) Check to re-enable Wi-Fi
Instead of "Connecting..." I now see "Scanning" and it picks up the routers around me! I selected my router, and it connected! I am now able to browse the web, update my apps, and all seems to be working normally now!

Man, you really had my hopes up with this one. You're the first person I've seen say every remembered network needs to be forgotten. But I followed your steps exactly, and my NC still will not connect. It sees all wireless networks available. It knows which ones are open and which ones are secured. I can go so far as to enter the password and click Connect. It says "Obtaining IP address from...", then quickly flashes "Unsuccessful", then "Scanning...", then loops indefinitely. I even took your steps one step further and rebooted before turning WiFi back on. Still doesn't work.
This is the fourth time this has happened to me. And every time, the only way I've been able to fix it is to completely reinstall CM7. That's not a fix, that's a wrecking ball. I'm pretty desperate to find a fix because my NookColor has become a joke, almost unusable. Right when I get it to the point of enjoying it and getting it set up just the way I want it, this happens. And the damn thing is useless without WiFi.
I also installed the latest nightly build, which was from last night. Nothing.
I have a stock unrooted Verizon Galaxy S5. For several months my phone has been plagued by several issues at startup. Whether I reboot the phone or start it up after the battery has died, it always enters an odd state immediately after loading and seems to get stuck in this state for an undetermined and variable amount of time (anywhere from a few seconds or minutes to hours or even overnight).
While in this state, this is what happens:
1. Screen stays on. Once I unlock the phone, the screen stays on. The side button doesn't do anything to lock the phone or turn off the screen. Holding down the button, however, still triggers the power menu. The screen timeout never triggers, even though it should turn off the screen after 2 minutes of inactivity.
2. WiFi and Bluetooth turned off. Even if they were turned on before I powered down the phone, they are not enabled when the phone first boots up. I can manually turn them on but the WiFi will not connect to a network, even if one is available. It may show it is connecting to the network, but it gets stuck at "Checking the quality of your internet connection" and continues to use the 4G network for data connectivity. This happens no matter what WiFi network I am within range of, so it's not an issue with the network or router itself. If I am not near a network at all I will still experience the other problems of not being able to lock the phone, etc.
3. Startup applications don't load. I have Tasker on my phone, but it doesn't load and show it's notification bar icon.
Otherwise, I can use the phone normally and open applications, surf the web, etc. It seems that loading some applications and using the phone eventually causes the phone to exit this mode, but I haven't been able to find a single particular application or series of steps to fix the problem. If I power on the phone and don't use it that just seems to make it take even longer to fix itself.
Once it gets out of it's weird state, the WiFi connection will become active (it will turn on WiFi if I haven't done so manually already) and it will connect to a known network if one is available, the phone will lock itself or I can do so from the side button, and things like Tasker and Power Save mode will turn on.
I am stumped as to what could be causing this problem or how to fix it. It seems the phone may be doing some kind of check, maybe related to Knox, that hangs during startup and prevents certain things from working until it straightens itself out.
Any clues into what this problem is, what is causing it or how I could further analyze this problem and determine its cause would be greatly appreciated.
Never heard of or experienced these issues. May want to contact Samsung.
Have you installed any official updates from Verizon at any point? I've heard of phones having phantom problems like this after receiving a bad update. I would definitely contact Verizon if you did update at any point. If not then like BigBot96 said, contact Samsung about the problem.
My wife's Note 2 did something similar when the battery died. I had to factory reset. Her phone was rooted/unlocked & running a custom TW ROM, though. May I suggest doing a complete factory reset and Odin. Backup data to computer or external sdcard since this will clear the entire device.
Edit: After rereading OP's post it actually sounds like an app is hanging at startup which could cause this behavior. A logcat should tell you what's going on.

I think it started when I accidentally put the Wi-Fi setting panel/app into multi-window mode. I already had an app halfway at the top and even though it should filter apps that are not multi window capable, the wifi setting panel was available and tapped on it. It could not be placed at the bottom half though.
And/or I played with NFC tags and wrote my network onto a sticker then read it back.
Ever since, Wi-Fi is unavailable. The toggle just toggles the icon state, but no actual connection is made. When I swipe down from the status bar again, the Wi-Fi icon is enabled again. Second screen icon doesn't do anything. I can't get the list of available networks as it's frozen and empty. After a while it says "Wi-Fi isn't responding. Do you want to close it?" This seems to eat the CPU so much it drained the battery quickly. How to I reset this or bring back the normal behavior? Device is factory unlocked H990DS, 1 month old and not rooted.

I tried:
Rebooting
Removing the battery and putting it back
Entering recovery with: adb reboot recovery (it didn't do anything just an icon with "no command")
Connecting via scanning my NFC sticker but it just freezes the connection prompt
Enabling hotspot (it doesn't turn on and cannot be configured, seems to use the same configuration app)
