[cm7] Wifi stuck on connecting..

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.

[Q]

My situation:\
-I'm connected to wifi
-I leave the area without turning wifi off, so I lose connection obviously
-When I'm in a new area and want to search for networks it finds nothing, and sometimes the settings app force closes
-It only fixes itself when it connects to a wifi I previously had a connection on.
What is this? It is driving me nuts! It is happening on every rom..
I've even went back to a factory image and did the cleanest rom install you could imagine, but the situation is still there..
if someone could help me out that would be great

Do you use Xposed or do you have any root apps that influence WiFi?

No I haven't got any apps that handle connections. It is really frustrating though when I'm in a new area and want wifi..
Any suggestions? Cause all I am being told is to flash a factory image and start over. Which is what I have done several times.

Can you get a logcat when this happens? I suspect that in your case it might be a hardware problem.

Android N wifi issue

Decided to install N a few days ago and test it out, everything was going fine but after returning home from work today my wifi will not reconnect. I've added the info for my wifi back in several times, the phone says the network info is saved, but it never connects or even appears in the list. Don't really feel like wiping again right now, so did anyone else run into this and manage to fix it? Any ideas? I've already tried all the usual stuff, but no luck.

Apologies if this is a silly response but is N official? I thought it was a beta? I'm assuming if that's the case then you'll get variable success with connectivity and functionality.
Do got have the most up to date vendor and is the kernel your using optimised correctly or should you expect issues!

Definitely not a bug. I have been using the preview since day one, and WiFi is working completely fine. Here's what you can try - wipe cache from recovery. And then if it still doesn't show up, you may try resetting your router settings.
I have faced such issue, but that would be subjected to all my devices connected to that specific router. Caused generally by lousy internet connectivity, or some router issues.

I had already tried doing both those things but the problem still persists. I guess I'll just have to try a factory reset or wait for the next update and see if it resolves itself.

The next update is near. In case you can't wait, factory/reset would be good option.

Went ahead and rolled back to MM and everything was working well, then I reinstalled N and wifi was again working without issue. I just returned home from an interview though and wifi will not detect my network again. SSID is still saved, but won't appear in the list or connect. Did a cache wipe from recovery, re-entered my wifi info, reset modem and router, but still no luck. So it appears to be something that I can replicate, and only with N. Here's hoping the next update fixes it.

I'm on the N beta preview 3, and my wifi will randomly stop working on my 6P. I have to switch it back each and every time. Also, when I return home, my 6P won't automatically reconnect to wifi like it did on MM. Definitely seems like a bug.

I am using the latest preview. Wi-Fi won't connect. It shows both the 2.4 and 5 ghz options as saved, but it won't use either one. Older version of Android connects fine to same router. I have a NetGear router.

same issue
Yes I would like to report having this issue as well on the 6P in N beta. I have a 5x on MM in one hand 6P on N beta in the other . 5x has connection fine 6P does not using 3 different routers.

Android N on 5x experiencing same issue. Any resolution?

I can report the same. Has anyone discovered a fix?

Wifi works great on preview 4. Might suggest a full wipe of your phone and flash again. ATTACH]3800543[/ATTACH]

Mine works well however if you turn it off and then travel away from your router with wifi off; it will fail to reconnect upon returning to your home wifi and turning it back on. Do you ever turn your wifi off for an extended period of time?

WiFi Issue
Don't know if related. In my case, cannot turn on/off wifi. Even while of it shows the progress bar as if it was looking for networks. Have no wi-fi at this point and unenrolling from the beta isn't sending me the rollback to marshmallow. This on a Nexus 6P

Temporarily fix
I found a temporarily fix till the next update (hopefully) fixes it. Hop to advanced setting and click on wps button. Wait for 5-10 second then click cancel. Hop back to wifi list and you should find your SSID. Sometimes it won't connect even though it's saved and appears in the list. What you want to do is keep clicking on connect. This should help, atleast it does for me. Nexus 5X on Android N.

WIFI turns on and off constantly

when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...

Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.

Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem

Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.

What rom version are you guys on?

I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin

I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok

same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed

Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?

its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.

AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.

mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI

I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.

I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.

I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.

BT keeps turning off

For the past few days, my BT setting keeps turning itself off every few hours. Once it happens, it then continues to turn itself off immediately each time I re-enable it. After an hour or so, it recovers and lets me turn it back on (until the next time a few hours later).
The phone is completely stock (APK1), never rooted, no 3rd-party power-saving, task-managing, or security apps ever installed, no power-saving modes turned on. It does not help to clear the system cache or the Bluetooth Share cache. Closing all open apps does not help. Rebooting sometimes helps temporarily, sometimes not even temporarily. I haven't seen the problem when I reboot in Safe Mode, so either it's caused by an app (I have hundreds), or else I just didn't leave it in Safe Mode for long enough for the problem to reappear. I have not recently installed any apps or made any settings changes. I've searched online and come across many suggestions but none are applicable and successful here.
Is there a system log somewhere that would tell me what is turning off the BT setting?

Try one more thing : Settings-> Applications-> in right top corner you have 3 dots, press and choose Show System Apps
scroll to Bluetooth share , click on it then click on Storage and Clear Data. go back and do same with Bluetooth Test.

Thanks, but that didn't help either. I found the culprit, though: the Walgreens app. When I force-stop it and then turn on BT, BT stays on. As soon as I start the app again, BT turns off. And I now see many other user reports of this problem, going back a couple of months.
It's annoying that without the user's knowledge or consent, Android gives an app unnecessary permission to turn BT off. What's worse is that there's no easy way to identify who turned it off.

There is an app in the store called App Brain Ad Detector.
After you install it you can scan all your installed apps and it will break down all permissions given to each app, show which ad network, etc. It is very useful!
Also after it is installed when you install a new app it will report if it does things not normal.. IE it would probably have caught that BT permission!
