Losing data connection (NOT wifi but HSPDA, EDGE...)

This is about all the data connection through the MOBILE provider, so not WIFI.
It is after x time when the phone is on. Maybe it is GPS related.
But bottomnline: the icon with the H or the E(dge) is there and it is even flashing for data, however every app stats there is no connection to the network.
After a reboot all is fine.
Other persons are also experiencing this : http://forum.xda-developers.com/showthread.php?t=675786&highlight=huuub
I am using cyanogens latest with one of pershoots latest, but other kernels show the same behaviour.
My guess is that everyone has this problem? Is this a bug somewhere?

This happensto mine as well. I just switch in and out of flight mode to fix it.

So why make a new thread if you've already found one that fits your problem?

I have not that impression. Why do you?

Oh, ok, I should trust you. If you hadn't told me to trust you, I wouldn't have, but now that you did tell me, I do.
I think it's a software issue, as do many other people. Never had this problem with tmobile on any other phone.
Oh, I almost forgot: trust me.

Does anyone here notice it seems to get lost after leaving a wifi connection? Like this bug?

I've experienced this more frequently on Cyanogen roms vs. Modaco's.

really a bug ?
ok guys, I am completely in a stock 2.1 rom .. no mods whatsoever and not rooted as well .. to get this problem, use wi-fi for a while(5mins example) and then disable it .. then use ur gprs/edge and see if it works.. the small E logo will show and the upstream arrow will glow white but downstream arrow will stay dark gray.. both should glow white when accessing the net but it doesn't after using wi fi .. this is really pissing me off having to restart my phone everytime this happens and I use both wi fi and gprs for everyday use .. can someone check to see if this problem is persistent ? thanks ..

Juicedefender is the cause
Ok, I figured out what was causing these problems. And I found out that after uninstaling Juicedefender my Cell connection returns. Anyway Juicedefender didn't seem to do so much for me anyway. (on the contrary I believe)
Can anybody confirm?

Help me with wifi problems... always autodisconnects

Hello everybody,
I really hope someone can help me with my wifi problems.
My wifi automatically disconnects. Its is not sleeppolicy or what ever.
The time between every disconnection is random.
It is really annoying when I use msn or when I am downloading something on my phone
First I thought that is was a rom problem, but it is not... I've been on different roms like stock, darkys rom and now CM7 Nightlies #95. With every rom I used I had this problem.
I think it has something to do with my installed apps. I always restore them with titanium backup but I have never restored the data or systemapps... so this is not a problem right??
When I kill al the running apps, the disconections stop for a minute or two but after that it......
It is really annoying and I hope someone could help me
Btw when I disable wifi I don't have any problems.

JB wifi signal

Hey sup everybody !
I have tryed all of the JB roms out there, but they all seem to have poor wifi quality
can any one confirm ?
thx

Sane here.
I'm not sure exactly what causes this but according to my phone I definitively get worse wifi through JB then ICS and GB.
From what I've picked up the way the phone picks up WIFI has little or nothing to do with the ROM you have installed. Perhaps since JB is more recent and used on the phones with higher specification the wifi picked up on our S's is the same as before but measures differently through JB?

not agree with you .Please flash Nexus Radio KF1 zip file from CWM or reflash cm7 JW4,JW1 radio files.

Did you try fix permission or configure Strong wifi from wifi power mode in Devil Kernel config app ?

Confirmed, wifi signal is poor on JB with every kernel.

You won't trouble any wifi issues if you flash JB ROM with full wipe and full format.Wifi signal bars show same levels just like in GB or ICS .

"specification" nor modem has anything to do with wifi strength

Same here, better WiFi signal strenght on ICS, MIUI GB than JB (doesn't matter stock or CM10). Tried all JB roms from xda, same problem.

Agree!
I don´t know... Maybe Radio files have to do something with that?
How can I find out which one I should flash?

I tried wifix and wifix manager , but nothing changed, this problem is so annoying I guess I'll get back to ICS or GB until they fix it

Modems/radio files have nothing to do with wifi...they are separated modules.
The wifi module is in the kernel. The right modems just give you better signal, with better signal, comes better battery, and i think it has something to do with the gps, but i`m not sure in what percentage.

WiFi was not working at all, Then something happened, Maybe I removed name and added it again that's what made it work, Not sure.

any hard evidence? show some transfer rates compares to ics.
maybe signal strength is not displayed correctly in jb?
bcos i dont notice any speed decrease on wifi since ics

WiFi seems the same as ICS for me. I have enabled the PM Fast setting in the kernel and also turned off the Avoid Poor Connections setting in the advanced wifi settings

Secure wifi
I am using Galaxy S(I9000) with JRO03H 4.1.1 ROM and ZSJPG modem and Devil 3_1.0.4 kernel. when I am trying to connect to a secured wifi it throws authentication error. ( I know nothing wrong with my user id and password as the same works on other device.) please suggest if this has to do with modem or kernel and is there any way to fix this.
Regards,

i second/third this .. i have a worse wifi signal in jb .. tried a couple of roms .
i am saying this based on the fact that i frequently use my phone in one room of my house and i always got 2 bars.... with jb its never more than 1 bar .. and to proove that its just not a reporting case .. i get frequent disconnects with jb which never happened with ics .. so there .. confirmed ...

This is a feature of JB that was added to prevent connection intermittently dropping due to a weak WiFi signal.
If you want the old behaviour go to WiFi settings, options -> advanced and untick "avoid poor connections"

Is really the signal weaker, or it is only a matter of scale?

help, WiFi connects to the wireless network (and shows connected) but doesn't browse

Hello all, please I have a problem with my phone's WiFi..
I am on Zeus Rom 7.04, my OB connects to the wireless network at work but doesn't browse. I can't load a single Web page, open play store or even do anything on the Internet.
It's also interesting to state that if I use my laptop connected to the same wireless network as a hotspot, my phone connects to the hotspot and browses just fine albeit slowly.
Any help would be appreciated

Your office WiFi might have IP restrictions. I Had the same problem at home ... it turned out to be a Problem with the ROM... however I could connect n browse but some pages wouldn't load ... a clean install fixed it..
PS were u able to browse before when you first flashed zeus or is it a recent issue?

Yes it's a recent issue. I was able to browse normally using Zeus Rom until recently when even if the WiFi connects, it still doesn't load a single page

My issues was the same as well.. I flashed a few tweaks n it stopped after that... a fresh install fixed it....
If u did throw in some tweaks, it could be because of that ... try using another WiFi network apart frm your wrk one n see if u can browse normally... if u can it's not a ROM problem...

GPS Poblems

Hi all.
I have been having problem with my GPS for a while. The GPS can lock on my device and find me when using the app, though after a while the GPS signal is lost. i was using SportsTracker, I have tried another app such as Endomondo though the problem remain.
I also tried using GPS Aids PRO but it appears that it didn't work or that I don't know to use this app.
I'm using C-Rom V6 (Based on CM10.1, Android version 4.2.1 AOSP) so if this is because that my ROM isn't official for SGS this would be really unfourtunate.
Please help guys, running 4 or 8 KM without mesuring my run is really, ehh, not fun.

Please help?

I use C-RoM too but didn't experience any problem on GPS.
Try clearing the data of your GPS app in settings > apps. It's important to have a clear sky area (no obstructions) to have good GPS signal.
If it didn't help, it's maybe a hardware problem already.There are threads on XDA discussing how to fix the GPS hardware problem.
