[Q] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?

I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.

Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.

I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help

Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?

Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

Flashing Modem ti solve wifi battery drain?

Hey folks, sorry to double post. Tried to post this on developer section(radio's thread), but i'm afraid i'm still under 10 posts...
Been having these WiFi/battery drain issues since updating to ICS, where WiFi is being called every now and then with some routers. So the most part of the time i must turn wifi off, even at home. Will flash another Modem help? If so, any advice on which one for spain I'm on stock ICS/LPY/XXLPT modem...
Let's see if can solve this, it's driving me nuts! Any help appreciated, Thanks!!
Cheers,
VR

Anyone?

I'd like to know the same thing for UK on O2. Thanks.

Allright, i've just flashed XXLB2 and nothing changed regarding WiFi. Running out of ideas...

Damn, still worse. Tried to flash ZCLP5 after xxlb2 and it failed. Retried XXLB2 and now i'm stuck on SetupConection Odin PC and te pone in download mode. Can i disconnect the phone and Turn it off and try ti start it?? Scary ti say the least....

Right, note reboot normally. I´ve trien XXLR1 with same results as XXLB2, wifi probs persist. Not a chance to try ZCLP5 & 6 as odin FAILS(failed message) to flash them. Any ideas?

Networks detected but will not register

So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them

same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?

Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?

back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though

WIFI ERROR \ Turnning on \ Wifi Goes To Grey

Hello Everybody ... Am a new member to Xda site but i learned alot through reading your posts long time ago...
anyway here is my problem MY GALAXY NOTE GTN7000 Wifi Is not Working....
Details: I Had The phone since febraury 2012 and it was GB 2.3.6
i Updated to I.C.S 4.0.3 Official Rom and rooted it in july 2012
suddenly in august 2012 the problem started to appear ((( Am Writing Dates so To Avoid the Possibility of Hard Brick or anything because the phone was working great till then )))
THE PROBLEM
1-When I Try To Open Wifi It just Lag and stop responding The ICON GOES TO GREY INSTEAD OF GREEN and stays like that till Reboot and some times stays grey after Reboot
2- when opening wifi from settings tab it says "Turning On Wifi " and stays like that Forever
3- the only Way To restore the wifi icon to white is trying to activate WIFI - Direct
4- Rebooting Used to fix the problem but now NOT
5- Removing the battery Used to fix the problem But NOW NOT
Fixes I Tried
1- Restore Factory Setting & Wipe Cache & Wipe Everything
2- Changing the Rom from (I.C.S 4.0.3 )to (GB 2.3.6 ) to (Paranoid Android ) to (I.C.S 4.0.4)
Sometimes after each format or rom flash wifi worked for 2 hours or even 24 hours normally then problem appear
3- Tried removing Wpa Supplicant ( Helped Sometimes Then NOT )
4- Tried Wifix TO change country code even manually did it
5- Adjusted the Nfram_Semacove i dnt remember the name actually from CC To All ( Worked then later Stopped )
6- Used Wifi Rescue (Worked for a while then Stopped )
7- I Flashed Alot of kernels ((Heared that syiah Kernal Fix this problem but nothing out for NOTE YET )
HELP
I know that many will think that its a hardware ISSUE BUT IF Its hardware then why sometimes it work !!!!!
What i really Think is : Its a BUG Changed some files of the system which are not restored by flashing new ROM !!! for example when i Flashed Roms and Kernels i Found WPA Supplicant unchanged with my router Config !!!!
I SENT THE PHONE TO CUSTOMER SERVICE AND THEY SAID WILL CHECK AND REPLY within24 hrs but for sure its hardware and change Board which means 2800 EGP which is the price of new SGs2 soo am sure its a Bug or Software CAN ANY1 Help MEEEEEE

I am also facing the same problem for last one month and tried almost all the options tried by you but no relief. Wifi just works some time and other times it stays greyed. Can any one suggest any other solution as i also think it's software problem.

jesus christ, we are not BLIND!
anyway, i have same issues on sgs2

Same issue
@MOHPHR : I am facing the same issue as you.
I tried several ROMs from Original stock ICS to Paranoid to Crisleko's ROM.
Going into the airplane mode and then turning wifi on used to work, not anymore.
3G Data works just fine, not being able to use wifi is frustrating because when I leave it alone, it connects by itself randomly when I am at home for example.
I have done some extensive research and found an article that mentions wifi hardware problems resulting from ICS update on a galaxy S2. (Google: Samsung Galaxy S2 WiFi Issue BY Shaiful Borhan )
I did use the *#*#526#*#* and got the status: "NotSet Driver loaded [NG]".
Anyone can help please ?

Hi, I have been looking for days now for a forum that will be discussing this exact problem. I ve had this issue fora month or so now. I have restored to factory settings but it has not solved the problem. My galaxy note n7000 is not rooted nor does it have any special rom. I wouldnt even know how to install them. Where you able to find a fix? I am so tired of this problem, Im even contemplating the possibility of getting a note 2 and selling my n7000. I believe as well that it is most likely a software problem and im wondering if the soon to come jellly bean update could fix this issue.
Ps: after the wifi problem started, ive also noticed freezes and restars/ reboots.
Thanks for your help guys.:good:

@fedetipito I am still considering the hardware issue, although it seems a compatibility issue with the region/country as @fearkillerr mentioned in this post (http://forum.xda-developers.com/showthread.php?t=1436683)
I tried his solutions, none worked. The script one worked, but only once, then the problem kept repeating.
I upgraded to JB 4.2 then downgraded to stock GB 2.3 still the same issue. I am from the North Africa/Middle-East region, although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue. Any thoughts ? This problem is really really upsetting as we cannot use the WiFi properly. I am seriously considering simply abandoning my Galaxy Note N7000 and go for an iPhone 5, simply because I cannot even sell it (since no one would like a smartphone that doesn't have a proper wifi working).

I am having almost same problem with WiFi after I installed Custom ROM.
I tried only one method and it worked like a charm.
Go to WiFi connections and tell your phone to forget the network you are connected to, then re log. This problem did not happen after that 3 days now. Good Luck.

@Valium10 we initially cannot connect to any WiFi network, so we can't "forget" them. I don't think it is a "wifi network" problem.

" although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue"
And if you take SIM card out and power-on phone?Will wifi work?

Sometimes no, sometimes yes. It's kind of a malicious bug.

I am also facing the same problem and it seems it is hardware problem. May some dust or something else on the hardware or else we have dropped our phone some problem is there. When I gave to service center they asked that the motherboard needs to be replaced. But they refused to check it without that. I told that first try without replacing any parts and just check whats wrong in this if some repair can be done, but the service center people are so busy 50-60 peoples were waiting in line behind me to give there phones for service. They do not listen anything. They have tried by installing latest ROM and nothing else, that we can easily do it and for that also they have taken service charges.
Please someone tell me where exactly the wifi module is there, so we can open and check the problem ourself.

S3 i9305 - problematic wifi.

Hello guys,
I just want to share this problem with my S3 LTE i9305, this unit came from singapore (singtel), and im now using it in Cebu, Philippines. However i am having too much trouble with its wifi always getting Authentication errors (when i was still in stock firmware).
I should say i can rule out that my wifi hardware is defective, because I was using the wifi yesterday whole night in our house. downloading stuffs from play store, browsing, facebook and etc.
This is what i already did:
1. downloaded a Hongkong firmware (official samsung stock firmware) flashed with odin with no problem. hoping that the wifi issue is just a corrupt base firmware.
- still wifi is problmatic
2. Im on Cyanogenmod 10.1 4.2.2 Jellybean
- all functions are okay except for the wifi
WIFI SETUP:
keep wi-fi on during sleep: always
wi-fi frequency band: auto
wi-fi region code: usa
wifi optimiation: unchecked
It can seem to detect new wifi with strong signals but whenever you connect to it the signal 'literally' drops to one bar, and stop doing the connection.
the problem is intermittent, meaning:
sometimes it works, sometimes its not - and there is no definite time when it works and when not.
here are the details of my current device:
Baseband version: I9305ZHBMI2
Kernel Version: 3.0.64-CM-g9c2e2b; [email protected] #1; mon sep 23 15:03:19 pdt

hello! sorry about early bumping.
with wiping phone flash stock rom <<-- how do i do this? and not corrupting any vital stuff inside my phone. I heard that EFS is a very important.
update:
if you're talking about these:
1.wipe data/factory reset
2. wipe cache
3. wipe dalvic cache
i did those stuff 10x already...
PROBLEM is INTERMITTENT: sometime it will connect just fine, sometimes not. << how am I going to work around this problem?
is there any way to low level diagnose the wifi system?
could it just be the hardware? - if hardware then there shouldn't be times that it can connect fine
could it be the software? - where to start?
How i wish someone can help me fix all these intermittent problems I am encountering with the wifi.

EFS etc its all in the Faqs and Guides .

Hi, i have been reading those giudes, and i havent encountered any special method of wiping as what you say... I have used odin to flash like 5x already, got into cwm wipe data, wipe cache and wipe dalvik cache...
I already have a backup of my efs in .img format, using terminal.
Can you walk me through?

Wipe phone flash stock rom and test .

I believe flashing via odin using stock samsung rom will wipe the flash. Is that correct? Or do you mean to say format the flash chip first before flashing with odin?... Im not quite sure how to do that.
Right now im using my celfone posting this message. Its just that this fone doesnt connect to other access points where the rest of wifi devices connects fine.
if you are referring to this guide:

I have tried alot of different ROMS already and the problem persists.
Could this be hardware related?
are there people whos got similar issue?
It can connect to wifi right away if you're 2 meters line of sight of the router/access point.

Yes it could be.My phone had intermittent wfi and data.Turns out it was an "RF loopback timeout" problem.Needed fixing at service centre.HTH.
