Wifi connectivity issues

Hey all, I was hoping someone else has had this issue and has fixed it. I'm running a stock unrooted phone and when I connect to wifi, it connects to the AP and obtains an IP, but I cannot go out to any website or use any app that needs a connection (facebook app, etc). Things I've done:
Restarted phone
Factory reset phone
rebooted router
Tried other roms
Sent to samsung (they did a SW update) x2
Forgot the network, then reconnected
This is getting extremely frustrating as it's been this way since I've had it, but it got worse with the ICS update. Anything that anyone has tried and actually worked? The funny thing is, when you reflash the phone or do a factory reset, it works for about an hour then stops. Thanks in advance!

Have you ever connected that phone to a different wifi?
I encountered an issue a few months back where something went wonky and i had to completely reset my router and set it back up. Have you tried that too?

Yes, I've tried different wifi AP's and none of them have worked, while others are on them including mine at home. I have not reset the router and reconfigured it because it's a cisco and as such is a pita. I have looked through my config and cannot find anything obvious. But still, others are able to connect just fine.

Same issue here. Never noticed it until recently. Reflashed LE1 and it worked for a couple of days. Going to flash the galaxy note modem tomorrow.

I know it's a shot in the dark, but some said it worked....
Try to disable the "UPnP" in your router.
Let us know....

premiatul: I can't find anything in my router for upnp. If anyone knows how to disable it in cisco ios 12.4(11)T1, I'll gladly try it.
Autx: please let me know how that goes and if it works. Thanks!

Is darkside wipe a temp or permanent fix, from what you've read?

Noone else has any info that may help? I would really like to get to the bottom of this. Devs: could this be a driver/kernel issue over a hw issue?

Honestly, whenever I'm running a TW based ROM I find that wifi takes awhile to connect. Any AOSP (CM/AOKP) for me is nearly instant.

I'm running a stock, unrooted device. It connects to the ap and gets an IP address just fine, but data doesn't go across the connection when I go to the internet.

Thanks for the heads up that the note radio didn't work. Also, the new official update didn't fix this issue either. Maybe I'll just have t-mo replace the device since it's not happening to everyone. Thanks all for your input!

Quick question.
Did you De-bloat your phone? Ie did you remove any apps from the system directory?

Not since the last time it returned from Samsung. And it's completely stock and unrooted right now.

I did a factory reset and the wifi came back steady for the past day I was slot more selective with my apps as I think this may have been the issue.

I'm glad this worked for you. I can't tell you how many factory resets I've done and it fails every time within a day. I bit the bullet and did a t-mo warranty exchange. Seeing as so few people actually have this problem, I'm chalking it up to my having bad luck and got a lemon. I hope the new one works fine.

I'd rather have a new one then the same one fixed lol

[Q] Bluetooth works but suddenly causes bootloop. Is this due to faulty firmwares?

Hey guys, I bought a Galaxy Nexus almost a week back but as its not launched officially in India its not under warranty and so I can't get it replaced.
Out of the box it came with ICS. Everything was going fine including Bluetooth file transfers. But the phone went to a boot loop (stuck at boot animation) when I tried to activate Bluetooth. Mind you that Bluetooth had been working fine, I got this issue all of a sudden.
I went into recovery mode and recovered my phone but all data was lost.
Later I updated to official stock ICS. Again the Bluetooth worked fine for few days and later suddenly went into a boot loop. I recovered my phone but this time too lost all my data.
Now I'm obviously very scared to use Bluetooth. Some people say that its a faulty firmware and I should flash another firmware.
What shall I do? Could this really be a firmware issue? And if yes then which firmware shall I flash and how to flash?
Currently I'm on stock JB on my GSM GNex which is unrooted and has a locked boot loader.

Never heard of this. With all data lost, do you mean the /sdcard partition as well?

I'm sorry I didn't get you. GNex doesn't have a SD card slot, right?

Bluetooth Boot Loop
Im having the same problem.. Please let me know if you found a solution.. I'll give you update if I find one myself..
The list of Android units that I have encountered this was with
2 units of Asus TF101G and 1 unit TF300T
My TF101G was fixed when I installed a Custom ROM (Revolution HD)
I'm open to rooting my phone but not to unlock the bootloader to keep the warranty..
Hard Reset fixed it but after a few days when I activate the Bluetooth it will start with the Boot Loop.. It's very frustrating to install apps and everything.
Perhaps is it related with the files I installed?

Afaik, bluetooth radio is controlled by the baseband. What version are you guys using?

Im currently using TF300T
Asus Official WW Jellybean ROM
I think It's not related with the JellyBean coz I expereienced it with ICS before when Im using TF101G

The baseband of my GNex is I9250XXLF1. I am on official JB (4.1.1) on yakjuxfw.
Please help me, this is really annoying and I'm very scared to activate Bluetooth now.

You are on the latest baseband and Android version. And since you are completely stock and the problem also manifested itself on ICS, I'm going to say you are probably having a hardware issue there.

That's really sad to hear. And as the GNex is not available officially in India, I can't get it replaced either.
BTW you said 'probably', what can be the other possibility?
Well I too have something to elaborate. Both the times (on ICS and JB), the problem occurred while activating Bluetooth from Notification Toggle (downloaded from Play Store). It's not that whenever I used Notification Toggle did the problem occur. Several times Bluetooth successfully got activated using Notification Toggle.
So as much as I feel that it could be a problem of Notification Toggle, I feel that the opposite is possible too.
Another thing is that I had downloaded a paid app for free from a torrent website. Tapatalk to be precise. Many of my friends suggested that and I wanted to try it out and so downloaded it from torrents. On both bootloop occasions, that 'pirated' copy of Tapatalk was present in my phone.
Now I have purchased Tapatalk, uninstalled that pirated copy, uninstalled Notification Toggle and now I just tried three Bluetooth transfers with my system (2 send and 1 receive) and they took place perfectly. Is it possible that the pirated copy of Tapatalk was causing the issue?
I know it's not ethical and even against the XDA rules to discuss about such pirated copies but I didn't want to hide anything when asking for a solution to my issue.

If the problem happens again, I think you have to return it to where you purchased it from as it may be a hardware defect. Let's just hope it doesn't happen again. And I know you mentioned India does not officially sell the Galaxy Nexus. All the best!

and yes, it happened to me too. Its bootloop, then i took the simcard out, then power on again, but takes a long time, only X logo for more than 10 minutes. Then its going to menu. Then, well, i check the settting, turn on the bluetooth again, bump ! it happened again.
FYI, device not rooted, bought three days ago, and its LOCKED.

The same problem with me!!
Not just in the GNex, it also happens with me in my HTC One V.. I can't find a fix anywhere on the internet? There's no one who can tell why this happens? I change ROMs but still it happens in every ROM! :crying:
I use Bluetooth for a few days... and BOOM! on one day it suddenly goes into boot loop....

That is exactly the issue I face, exactly the same.

[Q] Fried my GPS, not working at all on any roms.

I was flashing between CyanogenMod 10 nightlies and DrewGaren's Jelly Bean roms, wiping data every single time and always doing a clean flash when I noticed on CyanogenMod 10/05 nightly that the GPS wasn't catching any satellites at all. It doesn't seem like it's even trying because the GPS dot doesn't even come up in the notification bar. I tried using GPS Test and it just says 0. Same thing with any other GPS application.
I tried flashing to other roms to see if it changed anything and still no luck. Finally, I flashed all the way back to AT&T stock in ODIN and still no luck!! I'm thinking of just taking it to the AT&T store and see if they can do anything about it, I don't know the warranty situation since I bought it off of Craigslist. Anybody have any ideas?

Please don't go to ATT. We can't really help you since you bought it from a. craigslist and b. all we could do is get you to call warranty department in which case they may charge you since it was not purchased at the att store.

Do you know if the GPS ever worked??
Please go to dialer and type *#0*#. In that menu go to sensor test and make sure everything is working properly.
Go to http://forum.xda-developers.com/showthread.php?t=1767929 for a full list of tests you can do to make sure the phone is actually hardware damaged.

Got it working
Hey, thanks for the help guys. I actually got it working. Flashed stock rom with ODIN and did a factory reset and it just started working out of no where. This was after 0 GPS signal on many different roms for over 24 hours.
No idea what caused it to stop working in the first place maybe some kind of conflict with the Drew Garen Sprint based Jelly Bean rom or maybe something in Cyanogen Mod 10/05 nightly. Perhaps the phone got tired of me flashing so many roms and just needed to rest overnight lol.
If anybody else has an issue with their GPS not catching signal at all flash all the way back to stock and factory reset and hopefully it'll sort the issue out.

Wow, everything you described in your OP is happening to me. I believe this happened to me after flashing DrewGaren's ROM too (4 point something). I tried it out then went back to Wanamlite, my DD, and experienced all that you said. After Wanam I flashed 2 or 3 other ROMs and got the same response... no GPS.
Just in the process of Odin flashing a stock image to see what happens.
Edit: Back to stock, then factory reset. Tried accessing the GPS service menu but that didn't work. Final result is that GPS is not working at all and here is no indication in the status bar. Looks like I'll be off to the Samsung store for service...

I think the Drew Garen Milestone 4.5 has something to do with this. It's based on the Sprint leak and maybe that made our GPS wonky.
Just to let you know, the stock firmware I used was this one.
http://samsung-updates.com/get/648/Samsung_Firmware_SGH-I747_ATT_I747UCALG1_Android_4_0_4.html
Hopefully you can get it sorted out. Just wondering, how do you access the GPS service menu? Cause the code I know doesn't work on AT&T Galaxy S 3 at all so I want to see if the code you tried works on mine. Good luck getting your phone working.

Another reason why you shouldn't use DG roms? Lol
I'm running insomnia leaks with no gps issues. Glad to see the OP got his working again.

I did the same here is the fix.
Odin rooted stock ROM
Boot up as normal
Then do a factory wipe under settings.
You should be good to go.

Thanks for the firmware link but I am in Canada with Telus.
As for the GPS Service Menu, I saw some dialer codes for accessing it but they don't seem to work for our model.
It's weird how GPS doesn't show up anywhere on the phone now. Not the status bar or in battery usage stats. I am beginning to wonder if this is a hardware issue more than anything.

I know, it's like the GPS totally disappears from the phone, I thought it has a hardware issue too! I was actually on the phone with Samsung customer support and ended up fixing it while I was on hold.
On my first try I got no results too but when I downloaded the one from samsung-updates, flash via ODIN, and then factory reset the phone from settings that's when I finally got my GPS to work. They have the Telus software up there too if you want to give it a whirl. http://samsung-updates.com/get/2566/Samsung_Firmware_SGH-I747M_TLS_I747MVLALH1_Android_4_0_4.html
But at this point your only recourse might be to get done through Samsung customer support. Let us know what happens.

Thanks, that is the exact firmware I flashed. Just in the process of downloading the I747MVLALE8 version. I know it's older but worth a shot.
I'll update the thread as I go along but am most likely going to the Samsung store in a week or two so there will be a delay in my response.

The disappearing gpshappened to me also. I flashed dg's m 4.5 and thats when I lost gps completely. I did all of the above mentioned in other threads and couldn't get it too come back. At&t replaced it for me. I would advise staying away from sprint leaks I guess.

Update:
Got in touch with Samsung. They forwarded me to the warranty repair company located in my neck of the woods (Vancouver, BC).
Company is called Service Absolut, located in Richmond around Westminster Hwy and No. 6 Road. There is another in Montreal for easterners.
Regular warranty service is 3 business days for $0 OR 3 hour express service for $30. This place isn't too far from my office so maybe I'll give the 3-day service a try..... on second thought I think the $30 might be worth it for same day service. :cyclops:

I ran into the same or similar loss of GPS on DG Milestone 4.5 and 5. I was able to regain GPS on a CWM restore back to Milestone 4.
Really think this is a ROM bug that can be fixed in SW. I'm surprised to hear that some have had much tougher luck than I have.
Anybody heard anything from Drew Garen? (I don't have enough posts to comment in the main thread, or I'd be there)

Yep, this is exactly what happened to me.
I flashed DG's M4.5 and my GPS quit working. Very weird.
I tried 3 other ROMS and no luck. I ended up returning the phone.
Now I really want to flash DG's new ROM but it scares me...ha

Final update:
Took the phone to the service center. Tech looked at the phone and tested but couldn't find anything wrong. He replaced the mainboard and all is now fine. GPS is working well.
Next thing is to check out my new CPU now... I hope it doesn't suck.

Did you factory reset on a stock rom like everyone suggested? I was reading your posts and I didnt see that you did it. Could have saved you $.
That issue used to happen to me all the time in the Infuse 4g.

Thanks for the tip but I factory resetted the sh*t out of my phone, lol. Our phone (Canadian version) only has 2 official firmware releases for it and I Odin'd them both and performed factory reset on both, multiple times. Guess I missed that little tidbit earlier
I really hope this was just a one time occurrence.

So I ran into this same issue, although it was from flashing Smartguy's ROM and then going back to CM10. It does seem to be caused by using the Sprint leak. I was unable to recover my GPS with the above method of flashing to stock via Odin and doing the factory reset.
I decided to try going back to my Sprint leak via a Nandroid, this brought my GPS back. I then used my CM10 Nandroid again GPS was working perfectly, although I needed to use GPS test to get it working on CM10. Hope this helps others with this issue.

Note 2 has no GPS signal?

Hi all,
I just bought a slightly used Note 2 yesterday. Today, I tested the GPS and put it side by side
with a Galaxy S2 and my old gs2 picked up the GPS just fine, but the Note 2 did not even pick
up a single satellite even after 30 minutes. The GS2 picked up all satellites in 30 seconds sitting
right next to it.
I turned on GPS and use wifi/network location too.
This is a stock unrooted Note 2 running 4.1.2 stock OS.
Is there anything else I can do and try? I'm desperate. I searched and read all the posts on google and here
and found no solution.
Thank you
-mike-

I had the same problem the other day. I had to use odin to go back to an earlier stock version. The latest stock version did not fix it. Everything works great now.

Mine was unrooted and running stock 4.1.2. Are you saying that the problem is in the stock OS?
Is this a common problem? Which stock version I need to go back to?
Thank you.

No not a problem with stock. If you haven't flashed anything to your phone then I highly doubt its a software conflict. I've read on some Samsung phones the small screws on the back of the phone become loose causing no gps signal. You could try tightening them to see if that helps. My gps failed because I flashed a Verizon note 2 rom that I've used in the past but the newest version doesn't seem to play well. The stock version I flashed was from January. You can find all the stock roms in the development section here.

I tried the screws and they were all tight. I guess I will have to try different rom...
My GPS couldn't even find a single satellite sitting outdoor...

I would flash back to an earlier stock version and then update to the latest version and see if that fixes it. Just backup your data/apps/pictures first because you'll lose everything on your internal storage when you flash a stock rom with odin.

Thanks! I guess I can just use Odin to flash it as I don't have custom recovery?
Then, what do you do? What version did you flash on top of it?

I flashed tweaked rom. You could just take an ota update to get back to the latest stock version or flash with odin.

What did you do with the app to make yours worked?
Sent from my SGH-T989 using Tapatalk 4

I turned the GPs on while the app was open and saw the Gps indicator light up then I immediately opened maps and let it lock on my location I guess in my case it just kicked the gps in the pants I haven't had any problems since.
From the D's GN2

Did the gps test app show the number of satellites it locked on? Google map may not be a good indication because it uses wifi/data to locate you if it couldn't find satellite. Try something like 'GPS Test' to verify the number of satellite it locked on.

- just to make sure nothing else conflicts, I did a factory reset. It's running stock JB 4.1.2. Unrooted. Stock recovery.
- when I turned on GPS in setting and started google map, the GPS icon on the status bar did not even display
and of course google map could not get a fix on my location. This is outdoor. To be sure that my test location was good, I put my wife's Galaxy S2 next to it and turn on both. The S2 acquired position under 30 seconds with 14 satellites.
- i d/l GPS Test and it did not show any satellite
- I d/l GPS Status Toolbox and it did not fix it
- I d/l "TopNTP" to clear/download AGPS data and it did not fix it.
- I then sent it back to Samsung. The repair log said:
"problem found: cannot download sw/PRL. Solution: updated s/w. Reset. Quality Control passed. "
(when I saw 'cannot download sw/PRL', I googled it and I already suspected that it wouldn't be fixed. As most people
I found on google when they sent a phone back to Samsung all have this line "cannot download sw/PRL')
I got it back after 7 days and it was exactly as before I sent it out. Same firmware version, same OS version, same everything. True enough, same problem. How competent can they be? I stated that the problem is "GPS could not acquire satellite". How hard was it to test it? Just turn it on, turn on GPS in settings, run google map. Their quality control couldn't even do that and signed it off.
I called them again and I'm sending it back again. This is getting frustrated.
I still have the gut feeling that this is not a hardware problem, but what else I can try? I tried everything.
What are my options if they still can't fix it 2nd time? It's still under warranty (for another month).
Thanks.

I used this method to fix my GPS not locking. Take a look. It solved my problem but may not be for everyone.

Thanks! I will sure give it a try if it still does work when I get it back. It's now at Samsung repair center again.
I appreciate your reply.

Problem solved!!!!!!
I have a Note 2. The GPS did not work. No white circle on the status bar when GPS is turned on and it did not pick up any satellite. I tried everything including factory reset, restore OEM ROM from sammobile and nothing worked. I sent it back to samsung. The 1st time they updated some sw and sent it back to me. Nothing changed. Not working. I sent it back the 2nd time. they replaced some power management chips. I got it this morning and it did not work either. I called Samsung again and they remotely accessed my Note 2 and they couldn't figure out so they asked me to send it back the 3rd time. Before I sent it back, I followed a reply here on xda using the diagnostic code *#197328640# :
mainmenu>UMTS>Common>NV REBUILD>Restore NV Default
I selected it, it restored the NV from default and it rebooted by itself. When it came back, everything worked!!!!!
Before I tried this, I was l already on the phone with Samsung tech support for 2 hours and they even remotely access my Note 2 and they could not figure it out!!!

[Q] Is anyone else having GPS issues?

I'm running rooted, stock with stock kernel and my GPS signal won't get a lock. I can't use Nav or get my precise location in Maps either. I tried to reset my GPS data as well as download AGPS files, but neither proved successful. Does anyone know how to fix the issue?

yesterday mine wouldnt work at all. today it was really choppy..meaning the blue arrow jumped while driving instead of moving with me. denton, texas

Yes. Are you on 4.4.2? GPS is a known bug on 4.4.2, and 4.4.3 is supposed to fix it.

I am on 4.4.2. Do the rooted stock ROMs here have the update?

Unless they're labeled as updated or are 4.4.3, I would assume not.

just a tip, try downloading waze app and see if that fixes it!

I've had no troubles with this phone, but on my gs2 when I did I used a program from play store called "topntp" that worked wonders for getting a GPS fix.

There are no 4.4.3 ROMs from what I have looked at and if there were, none were TW, stock. Tried the app the previous post mentioned and had no luck with it. Using Waze isn't a solution to the problem, simply a workaround and I hate the UI of Waze, which is why I use Maps instead. There has to be a fix for this issue. I've ordered a replacement device in the meantime.

4.4.3 has not been released yet so there will not be any ROMs using it yet.

So what is a fix for the issue?

I don't seem to have the problem for what I use the phone for, but then I don't use navigate often. I do use one of the AGPS updater (can't recall which one at the moment) and I do get a good lock fairly quickly (under 4s).
If there really is an issue however, the fix is in the updated Android 4.4.3 release which as already stated has not yet been released. So there is no "fix".

Just sayin, it is a little better then the main apps page like live updates which includes traffice, the actual time youll get to your destination, accidents, and so on.....your probably the first one that doesnt likes waze......you did ask for a fix......i had the same issue with mine on non-rooted and rooted devices and thats the reason why i use waze, it gets the job done better then the main navi app. but it might be a faulty equipment, get it swapped but note that it will be a refurbished device

Waiting for the next update and hope it would be fixed.

I'm still on 4.3 and have problems with GPS locking on. Phone also gets very hot, when using a navigation app.

I'm on DarthStalker v6 4.3 and I've been having GPS issues. Try downloading the app GPS status and running it. Every now and then I'll use it and it gets a lock on the satellites quickly.
