[Q] Wlan range problem - Galaxy S III Q&A, Help & Troubleshooting

Hi,
my Galaxy S3 (GT-I9300) has stock rom(4.1.1 and 4.1.2) and has problems with the wlan.
I can only connect to the wlan if I go to the router to a range of 3 meter.
Otherwise I can see the Wlan with good signal but I allways get an authorization error.
I have tried this with different routers and it is allways the same.
Also tried a factory reset with the S3, but nothing helps.
And also when it is connected it is really slow. (see attached screenshot, I was sitting 3 meters in front of the router)
The Wlans all work perfekt with all ohter devices, like Notebooks or my old Desire HD.
I hope someone can help me
Best regards,
Michael
I sent my S3 to the repair center, and it is now working fine. They repaired the Hardware.

Use your phones dialer type *#0011# press your menu key hit WiFi then turn power save mode off. See if that solves your problems. There is threads about this already.

Xperia Sola Wifi Problem

Hello guys
My Sony Xperia Sola was perfect until i updated to ICS. ICS is very fast,smooth and beautiful software but since then i am experiencing a wifi problem. My wifi get frozen and stuck to connected. I can't disconnect it. The only way to disconnect it is to switch of the phone. I foundnd a "solution" to this problem. Problem seems to disappear if you make a factory reset of the phone. But after a week it comes again. It's so annoying. My "solution" is to make back up-and restore once a week to avoid the problem. If i didn't do the factory reset problem comes again. Is there any solution to this issue? I heard a lot who have this problem after updated to ICS(problems appears and to xperia u)
Thank you
Patrokloscy
Please post Q&A in the appropriate section next time

Any solution guys??
Change the wireless interface on your router to be 802.11 b/g only - not b/g/n
that helped me!!
sola wifi prob
i have the same problem, i restart, format, anything, but the wifi still doesn't turns on.
even at the first startup screen, i clicked connect only using wifi, than i select network, after that it just stuck there and the wifi will not turn on forever...
i had formatted my phone at least 3times today...
can any1 tell me y???
and how to fix it???
credit to @[email protected]
flash ur device using flash tool, it can be found in the forum too, and it shall be fine after that, just dont know that how long it can last...
same issue
I completely understand the original post.
I don't want to bother with any routers, 'cause it had been working fine before. It mustn't be a question of router settings.
Some software upgrade of the phone might have caused this problem and I'm still waiting for any reply from Sony on this. If they don't do anything in a month I'm gonna push this **** device to a repair station, though I don't feel much desire for the mess that comes with this procedure.
Generally the phone is very slow (and sometimes it opens the phonebook instead of call list, sometimes it take 10 secs, etc.), I wanna get rid of it but I have to wait till the end of my telephony contract's period.

Got a similar problem to yours, have you been able to solve it? My WIFI was working perfectly fine at work today. Starting last night it took a while for it to connect at home and tonight it is not working at all. It sees the netwrok, its obtaining the address, authenticating and the rest of it....and thats it. Once or twice it said that the network is too weak, which is just impossible. Before today never had a problem with WIFI at home. WIFI works perfectly fine on the rest of my devices at home. Please help, if anybody was able to solve the problem!

Anyone can help with this problem?
my HTC Butterfly which i bought last year was working fine until last night. Now the WiFi signal strength is having difficulties to reach full bar, i mean full signal...most of the time it receives poor signal. The problem become worst if i try to use whatsapp or skype. The connections suddenlly disappeared. A few minutes back it connected again.
I read from this website. they have suggested a few things - like resetting my wifi router (which i think it is not the problem. the router working fine, as my friend is using my wifi using his iphone), then i try to restart...i have restarted - my phone, my wifi router...but still, the signal was very disappointing.
Then, at last, i decided to reset the phone..which at first, i really try to avoid as a lot files i need to back-up, the problem is, i could not back-up to my dropbox account as this one require good connection as well. So i jumped straight resetting my butterfly, my beloved htc butterfly.
Then, i noticed, it has improved a lil bit...(i mean the WiFi signal/connectivity), but still, if i try to download big size of applications or using skype, the connectivity disappeared. Anyway better than the previous (before resetting).
Now the signal still did not reach full bar (like it used to before).
What can i do next? should i reset again?which i dont think might resolve the issues.
What happen actually? I dont recall that my phone did fall down or anything. I dont browse any porn (they used to say, porn site contains a lot of bug/virus/malware etc, they sayy..)
FYI, this is the detail of my phone, i just list down everything perhaps somebody out there can help me.

I have the same issue with my headset. Hope someone will find a solution soon.
I too have same problem!!
Whats wrong with samsung!!, sometime Wifi problem and sometime bluetooth.:silly::silly:
earlier I was on 4.1.2 and it was working good with my jabra clipper bluetooth headset, after updating to 4.4.2 it sucks!.
according to my observation,
The OS is trying to save battery by limiting the bluetooth signal strength!, and the same problem with wifi also.:silly:
Looking for a workaround. If i find any will post for sure.
I have the same issue with my Note 2 after update to 4.4.2..
It seems to be a distance problem with my headset, every distance more than 50 cm creates
sound break up´s .. In my car the phone has a fixed place, it happens too, but not this much.
Maybe it is caused by a lower power managment for BT after update ?!
Found some others having the same issue e.g. here

Hi
and have the same problem with the bluetooth, the phone in my pocket, Samsung headphones on the head and lose the music signal, conclusion .... android version
Before to upgrade I had 4.3 and works very well and now I upgraded to 4.4.2 my Note 2 with Phantom_V7.0 and work awesome but has a minus....... the bluetooth signal gets lost and it's not about the power,for ex i have battery with 4200 mAh
I will continue to keep looking this problem and I will return
There is no way to get better connection. The only way is using a 4.3 ROM
Seems like the problem is solved.
Hey guys!
It seems to me I’ve found the solution!
But firstly, a few words about the problems I’ve got…
I have Samsung Galaxy Note 2 and, when I decided to replace my old Plantronics Discovery 975 with their Voyager Edge, it had installed Android 4.3.
Both events, start using the new Bluetooth devise and upgrading to KitKat (4.4.2) occurred almost simultaneously, so it was pretty difficult to recognize what was the source of the problems that I run into – hardware/firmware issues of Voyager Edge or KitKat’s quirks. The problems were the following:
- Poor Bluetooth connection that resulted in distorted sound (not always, but often) thru the headset.
- Regularly losing the ability to use various Edge’s features, such as calling back to the last number, checking the battery status, recognizing who's calling, etc.
- Note’s battery drained badly – instead of 50-60% left at the end of the day, I got 10%...
I spoke several times with Plantronics support, but they ended advising me to replace the headset. I have neither found the specific solution in the internet and it was even reported that the factory reset would hardly help. So, that was almost the dead-end. But there was one pretty weird solution that helped to some people – deleting the duplicates in the phone’s contact list. But, since I had NO duplicates, it didn’t seem to be helpful. But then, I noticed one very strange detail – during the moments when Edge worked properly it correctly pronounced the names from my phone book, even tho some of them were quite unusual for English speaking "robot". All of them, but one – my mother’s record, which was a simple “Mom”, but when she called me, the Edge’s notification was definitely not “calling from mom”…
So, I just renamed “mom” to “mother”!
Guys, can you believe that, but ALL the problems (both phone’s and headset’s) have just gone! I’ve been using it for almost a week already and it’s OK. So, you may check your contact list, whether it sounds correctly.
Well, one issue left – weird/funny bug of the Edge’s firmware – start playing music when you take it off the cradle. (2 latest firmware updates didn’t cure that…). I just long press the voice button on the Edge to pause it. Not a big deal, to be honest.
Oh, just one last note – since Voyager Edge cannot be rebooted you can do the following if/when you neither hear the music (!), nor the report that the headset is connected when you take it off the cradle. Just long press the Call button on the headset (in my case it runs Note’s S-voice) and then everything works just fine. (Checked twice.)
Hope that this will help you too.
Cheers,
Max
Hi Max,
nice story, but I can't belive that this entry or change of entry will make the BT signal better.

Hi Harvey,
Absolutely the same reaction was mine, when I read the comment by dawolverune (see page 1 of this thread). How deleting duplicate contacts might help…
Well, if assume that I tell the truth (and I actually do! ), then the solution may be explained in 2 ways: a) logical – I’ve been hammering with all this stuff for almost a week and nothing helped until I renamed that single contact and then, it just start working and b) technical – since Voyager Edge pronounced the wrong name it means that it took it from somewhere, but definitely from the wrong place and this might require extra “efforts” from the Bluetooth receiver/transmitter, etc. This indeed may result in abnormal behavior of the devise and “eating” the battery. If re-phrase the title of S. Coppola’s movie – here we had “Lost in Bluetooth” case.
Cheers,
Max

SOLUTION OF BLUETOOTH DROPPING after 4.4.2 update
Yo !
I found the solution. No one has to downgrade Note 2 (N7100) to Jelly-bean in order to fix the Bluetooth range and WiFi dropping issue.
The fault is with the latest update from Samsung itself, May be it is a tactic to make people shift to the newer phones.(who knows) !
Anyway the solution to this problem is to Flash it with Odin it a previous release of 4.4.2.
In my case which is from the INU (India) region the release of August that is 29.08.2014 is a faulty update.
So i downloaded the older one and flashed it.. then everything worked perfectly as if the phone was new
Here is how to do it:- [BACKUP YOUR PHONE WITH KIES 3]
1. Check your version from *#1234#, Compare the version with Near August version of your Region. If it is same you better change it to get a way better performance.
2. Look up the earlier ROM version released from samsung-updated .com , http://samsung-updates.com/device/?id=GT-N7100&details=Galaxy_Note_2__International , I personally flashed it with the first version of Kit-Kat that came for note 2 in INU region. on the 8th April (08.04.2014).
3. Download ODIN http://www.mediafire.com/download/mbvtjub21ehsxrl/Note+2+Odin.zip
4. Install Samsung USB drivers http://www.mediafire.com/download/9qaqkld45387lzi/Skyrocket_GSII_ADB_Drivers.zip
[IF THE LINKS DON'T WORK then GOOGLE THEM AND INSTALL]
5. Power off your Samsung Note 2.
6. Hold Volume Down, Power, and Home Buttons at the same time. You will enter the ODIN DOWNLOAD MODE on your phone.
7. Press Volume up to Continue. It will Show "Downloading" "do not power off"
8. Connect your device to the PC where you have put ODIN and the md5 file (Firmware you want to flash with)
9. It will show connected to your device name on the top left of ODIN which means that it recognizes your device.
Click on PDA and select the firmware that u downloaded to flash Note 2 with.
It will lag for a few seconds but let it take its time.
When it is done. [Refer Image attached]
10. Press Start [It will take around 5 minutes, 3 minutes give or take]
11. It will Automatically Reboot your phone. Do not disconnect the USB cable.
After the boot is Complete ODIN will show a PASS on the left Side. Which means that the Flashing Process has been a Success.
If it shows fail then Repeat the process from STEP 6 all the way till STEP 11.
{ RECOVERY STEPS:- this will wipe all your data}
[Also, If device is Stuck at setup connection or on any other process, then disconnect your Note 2 from PC, close Odin, remove phone’s battery and put it back inside AFTER 5 seconds, press Volume up, Home key and Power key at the same time, When the Logo comes then Leave the Power button but keep pressing the other 2. Wait for it to show MANUAL MODE. Select Wide Data and Factory reset with Volume down and press power to continue, Then again wipe Cache.
Select Reboot . Now it should work perfectly.
CAUTION :- DO THIS AT UR OWN RISK.
Is this problem appears in official update? Want to update, but dont want any probs)
Yes the problem is with the official update. Better not update it till there is another update of it available.
I'm thinking this might have to do with Samsung dropping the Bluetooth version from 4.0 back to 2.0. I have no idea why they would do that but I've been wondering why my phone listed version 2.0 when the specs for this phone always said version 4.0. As you can see my debug screen shows it as version 2 and not 4.0. My Edge shows 4.0 on that same screen. I can't recall if older builds for the Note 2 had 4.0 listed but I believe they did and kitkat lowered it. Guess that's their trick to get people to upgrade, break things on our phones quietly...

Problem with WIFI about Pry-Fi

Maybe someone else had this problem before, I didn't found a comment about it.
My phone can't see any WIFI's, it seem as is it turned off.
If I turn on the wifi after by hand about 10 second the green light goes out again
and also during this time no wifi can be found. There are no wifi's at the list.
I have used the app Pry-Fi 1.21B and during first time using the application hungs.
After a reboot of my phone it was not able anymore to contact the lan or the WIFI.
I have found out the into hosts file ( /system/etc/hosts ) was a wrong entry,
after removing that the network itself works againt but no more WIFI can be found.
older versions) it comes always the message "creating backup".
I've made a reset to the basic setting and as next a Factory Settings reset, nothing will help.
I'm using G900FXXU1POJ1_G900FVIA1POI1_G900FXXU1BOJ1_HOME.tar.md5,

I'm nearly sure it has nothing to do with the used software version.
Do you have a idea how can I solve my problem?
On request I can send you all the hard & sorware details of my Samsung Galaxy S5.
Thank you in advance.
