Possible fix for wifi freeze

Ever since I downloaded gingerbread I have noticed (and I know I'm not alone) a wifi freeze that would occur everytime my screen would turn off. I've tried countless factory resets, reflashing recoveries, and apps like wifi reassociate and nothing seemed to work. When I reset my phone it would seem fine till I uploaded my go launcher app . Since then it wouldn't work, so I tried uninstalling it and vuala it works again and flawlessly might I add. I use the wifi off Wm screen is off feature in advanced settings and once I turn on the screen within 5 seconds the wifi is on again as well. Hopefully this is a fix for others as well..

sorry but just to clarify, are you saying that wifi freezes with go launcher only?
because I think that many users here are using launchers that differ from go launcher and yet they are facing this issue.
btw I am using stock 407 since a week and never once the wifi froze (touch wood!)

What I've noticed is that when WiFi stops working after the Dell Streak has been on standby for a while is that if I switch the device to Airplane Mode, then off Airplane Mode, it works properly, till it's been on standby for ages again. Small annoying glitch, but I deal with it.
It never freezes while in active use.

I'm using DSC 0.66b with Phoenix kernel and also noticed a problem with Wi-Fi freeze, but I fixed it by simply going to Settings > Wireless & networks > Wi-Fi Settings > Advanced and changing Wi-Fi sleep policy to never and then letting Green Power app to manage my Wi-Fi. Good enough for me, maybe this will be useful to someone else as well. Cheers.

I have tried 'wifi fixer' but it's not working for me...Can one please explain what is causing the problem actually? Is it caused by device or OS

Tried it, but after a few days uninstalled

The first few days it worked. But after awhile Wifi Fixer started giving me issues, specially using 100% of the CPU. I unistalled it. I couldn't take my Streak being slow.

The same thing was happening for me also. However, the problem went away after I re-flashed the 407 recovery and installed the Olleh ROM again on my streak. Fingers crossed !!

I was able to fix my wifi problems by setting up a static IP on the phone and router. I have a detailed post in the DSC Rom thread...

I've noticed a lot that with 407 the wifi shows as connected, but won't work until I turn wifi off and on again.

I hope this helps
I was looking into this WiFi freeze and ran into the XDA's crew. Is it possible to have mobile data working perfectly? I can't locate my sim card I believe its built in. My WiFi is set to off. My router will resume network if I turn wifi back on. The weird thing is. I have no data plan on this phone, its been down for years. I was shocked but it didn't help with the freezing, it was if I turned WiFi back on. Then the old Vibrate, Stall.ing, vibe one more time then the WiFi freeze thing.
Still on topic don't worry but that talk about go launcher. It "was" recently installed on my device. Till we all started doing data wipes Hahaa. My point is. As a fresh data restore no apps installed yet. My Google Search suggested that I use explorer, youtube or tubemate to view my search? I dont have that installed anymore I'm a changed man.. Thats why I brought up your Go Launcher theory. Maybe both launchers are interfering I guess, cuz I wouldn't know. I'm only here to give XDA's more Details so they can do what they do best...
My Samsung S738C is running 4.0.4 ics
Basebands S738CWYMJ1
KERNEL 3.0.8-1251199
BUILD IMM76D
Start with Go launcher or if there's anything this Noob can do. Won't be much

good job
thank you very much sir !

Bluetooth Issues

So, for some reason, my Bluetooth doesn't function properly as it should, which is weird, since my phone is still on stock, and the only modifications I've made are unlocking the bootloader and rooting the device. I also installed Power Toggles, but I don't think that's the issue at hand.
Pretty much, whenever I turn the bluetooth on, it tries for a while to turn it on, then gives up and won't let me turn it on. At that point, I have to restart the phone, and when it reboots back up, the bluetooth is on without me having to start it up. Then it works properly, but if I wish to use the bluetooth again the next day, I have to repeat the process of rebooting the device. Any ideas?

I had this issue when I Downloaded a FM radio app from the Play store to see if it would work. I just deleted the app. Went into safe mode then into normal mode and it fixed it.
Don't know what you case can be. But you can try going into safe mode and back to normal and see if there are any different results.

I had this same problem after installing Torque, and using it with default settings that auto-enabled/disabled bluetooth. After turning all that crap off it is back to normal.
I use bluetooth for audio playback and an hf/A2DP headset dialing via Motospeak, as well as Torque with a bluetooth odb2 interface, and it all works perfectly since disabling Torque's auto-bluetooth settings. My only issue is that it takes Motospeak a bit long to restore audio playback after a hf call command.
I would look for an app that you have that is the controlling bluetooth on/off.

I wonder if it isn't a software bug. I have the same issue but I don't have any apps that are causing the issue of atleast from what I can tell. I'm also unlocked and rooted.

I removed Bluetooth from Power Toggles. It's been two days and all seems well. Now we wait.

Similar problems here, the weirdest thing is idk which app causes that. Because I didnt install that much. Only thing I notice is it happened when the wifi is on.. Does anyone have similar problem??

Same problem here. I have a lot of apps but none I can think of that do anything with Bluetooth.

Nope, still doesn't work.

Nothing yet? I'm just curious as to whether it's just a few people experiencing this, or a lot, since there doesn't seem to be that much talk about it.

I use Bluetooth everyday on my way home from work just to connect to my Bluetooth headset. Out of 14 days I may get one day where I turn Bluetooth on that I don't have to reboot for it to work.

So we're on 4.2.2, I've went through safe mode and back a few times, and I've uninstalled and installed applications having to do with the Wi-Fi. Problem still seems to be there. It's just somewhat of a hassle to have to power down my phone completely, then start it back up, everytime I get into my car. I feel a hard reset mighttt fix the issue, but just looking for another way as of now.

My phone also have the same problem.. the bluetooth won't turn on.. stock 4.2.2 locked bootloader and not root yet.. anyone has a solution..

[Q] Stock Rom keeps turning wifi on

I'm using the stock Rom and when I go to settings to disable Wifi, after the screen is off and I wait for a few minutes the wifi keeps turning itself on.
Anyone else experiencing this?
I'm not using juice defender or similar apps. Also my phone carrier doesnt add a custom APN that forces this.

Go into settings/wifi/settings and choose wifi on always in sleep mode. Reboot the router and reconnect to wifi. If that doesn`t help you might try a data factoey reset.

If it wasn't a stock rom I'd say something like profiles.

Do you use Qualcomm Battery guru? I also have this issue and I use it, so I think it is related to this.

Hi,
I just tried this and I don't see anything suspicious. If I search for Wifi, I see it's being set to ON by ActivityManager or ConnectivityManager, it doesn't seem to come from an application.
I have attached a full log and a log searching for WiFi, maybe you can help me find something?
Very much appreciate it!!
Thanks!!!

Anyone? :angel:

WiFi hangs and drops

Hi
I'm currently having a problem with my S4 that is driving me mad.
Ever since I got the phone I've had a bit of a problem with the WiFi connection. I've flashed a few kernels and some seems to help the problem more than others but it's still there.
What happens is the phone connects to WiFi no problems. Then maybe after a few minutes of use the phone won't give me any data. If I search a Web page it just hangs and then says unable to display web page. I then have to knock the WiFi off and back and and it cures the problem temporarily.
Sometimes the WiFi connection can be fine and last a few hours without hanging. Other times it can last a few minutes. The WiFi icon always remains on the screen and the arrows act as if data is getting processed but nothing ever happens. The odd time it will also kick itself off the WiFi and reconnect.
It's driving me mad having to constantly knock it on and off. I'm missing WhatsApp messages for hours because of it also.
Is it a common problem? If not the phone
is still under warranty so I will have to send it back but then that's me phone less for god knows how long
Any help would be great.

if you are rooted, flash this http://www.adrive.com/public/8DJWtV/WifiFix.zip
its a fix that sorted out my wifi problems

I think you should revert back to the latest stock and reset your modem. There might be some fancy settings in your modem software that need to be turned off. I read that somewhere but can't remember which ones. Just search on here.:cyclops:

Hi guys, sorry I've just seen the replies and thank you for taking the time
I shall have a blast at both your solutions and report back.
Thank you again

Well I tried the WiFi fix but that hasn't cured my problem. Today I will flash to stock rom and then re-root and see if that makes a difference. If not its off for repair under warranty and the old Nokia 8210 will be coming out of retirement for a few days lol

May be a fix?
1) type *#0011#
2) press menu button and select wifi
3) turn off power saving mode
4) restart
Alternative
1) download terminal emulator
2) type ping google.com

Hi jehbrian.
I've never heard of this fix but I'm willing to give it a go (whats the worst that can happen lol).
Done the above and indeed you get to a point where Wifi power saving mode is on. I've knocked it off and will see how I get on in the next couple of days. It does make sense that the power saving mode could be killing the Wifi every now and again.
Thanks for the tip and have a pleasant day :fingers-crossed:

I had tried that one. It spends about 10% more battery.

Does it?
Surely there must be something else that can compensate for this loss if it means the Wifi actually works. GPS? Bluetooth? Screen brightness?
My phone is on my dock so can't verify the loss of battery.

I've never noticed the battery drain... besides, S4's battery life is bad anyway.

Wifi function fail (turning off involuntarily)

Anyone else having issues with the wifi turning off on its own? Got my S5 yesterday on AT&T. There have been a few times that the wifi will turn off and it can't be turned back on unless I restart.
I've experienced this with wifi settings as is out-of-the-box and when I changed the option to only have it on during sleep while plugged in.

Try this, go into settings, press wifi, then press the button consisting of 3 dots in the top right corner and then press advanced. where the settings state "keep wifi on during sleep", make sure it is set to always.
also check the wifi timer is not on either.
Let me know how you guys get on

I have the exact same issue and am thinking to call warranty and see what they can do. This happens on any router, very annoying. You can avoid phone restarts btw, just put the phone in airplane mode and back in normal, when you do that it will be able to turn wifi back on. I am wondering is this bug on every att galaxy s5?
this bug occurs when you have the keep WiFi on during sleep option off. this saves a lot of battery, and to me avoiding this option isn't a fix to the problem, because on every android device I have I make sure WiFi turns off during sleep and never had issues reconnecting back when I wake up the device but galaxy s5 has that issue
