[Q] Wi-Fi To 3G

Hi,
Got a really annoying issue with my Nexus One that has been happening since the Froyo days, when I leave home to go to work I turn the Wi-Fi off on my phone to save battery. Sometimes I use the widget sometimes I go through the settings.
The problem is that the 3G doesn't alway's kick in, the only way for me to get 3G working is to turn my phone off and on which always works.
Any suggestions on why this is happening and how to resolve them?
I am running Stock Ginger Bread on my Nexus One on the the Vodafone network in the UK.

Try checking your signal strength: *#*#4636#*#*
You can try to enable 3G only and see if you can keep a signal.
My signal is sometimes intermittent due to topography. Stupid flat Ohio. Haha

Thanks, it won't be that though because once I turn the phone off then back on it's there. Also once I turn W-Fi off and 3G doesn't kick in, then it won't do untill I restart. Also another reason why I know this isn't the case is because even when I do this at work 3G doesn't kick in and there is a Vodafone 3G mast on the roof

never seen this problem before, but it sounds like something that might have to be fixed by doing a full wipe and reflashing your ROM. i know its drastic, so maybe do a nand backup first. then flash and see if the problem remains. if its still there, than just go right back to your backup and no harm and nothing lost. worth a shot.

I'm on a stock Nexus One unrooted so I shouldn't have to Root to fix an Android problem. Never Rooted before but considering it.

I got the exact same problem with Froyo and Gingerbread ROMs, can't remember if I had that issue with MIUI ROMs, but definitely with CyanogenMod ROMs.
Instead of rebooting the phone I suggest switching flight mode on/off it's faster than a full reboot
Haven't found any real solution yet and always thought I'm teh only one with that problem as I couldn't find any other person with that issue. Right now I'm testing different Radio/ROM combination and if that doesn't work I'll need to check if any app is causing the problem.
Any chance you are using Tasker?

I used to use Tasker but uninstalled it when I thought that it was causing this, it wasn't. Thanks for the tip about airplane mode, worked a treat.

[Q] O2 - Mobile internet has stopped working! :(

Hi all,
I've had SGS for over 8 months now on O2 Contract, UK. Currently running on Darkys Rom. Everything was great until yesterday morning the mobile internet has suddenly stopped working!
I've tried everything; Re-setting the correct APN manually, Switch on/off, Taking battery out. Called O2 & and tried to reset with their assistant but none of it worked. The network seems to be up and running fine on their side.
The symtoms are; I do have the 3G icon on the bar (Displaying 'H'), since I usually get a good strong signal in my area. The problem is, when I start the browser, the google.co.uk webpage works ok-ish. But for any other sites, doesn't work. Can't access email or facebook or anyother internet related apps. All connections fail.
I have other O2-Simcard. And when I try to use internet on my SGS, the same problem occurs. (Websites load less than half and everything stops) The sim cards work fine in my other phone.
Could this be a hardware problem?
I didn't drop or anything, I've been taking a real good care
Somebody please, please help!, Please.

You say Google works therefore internet works .Errors are possibly elsewhere in settings .
Worth doing a factory reset after backing up data to see if that clears the problem .
As its yet another Darky rom problem i suggest asking Darky if above fails .
Hardware probably not blame the rom or settings first .
You will have to remove the rom if you need to make a warranty claim .
jje

I agree with JJ, this sounds like a ROM/Settings problem. If you can get Google, then your hardware is fine. An Antenna failure is usually all or nothing.
Maybe check in Settings/Wireless and Network/Wireless Network Settings/Network Mode and make sure it is still in Auto mode, or switch to 3G only?
As a last resort, flash to a stock rom and see if the problem goes away.

Thanks, guys! JJEgan & rschenck.
Network mode has always been Auto mode & I tried all options but no luck..
The thing is, the 3g internet has always worked fine with Darky Rom. It's just that this happned all of sudden.
I guess I'll try factory reset first, if it doesn't work, I'll then flash to stock rom.. Glad to hear it probably won't be the antenna failure.
I'll keep posted after I try!

Hi guys, I'm still at work so haven't had a chance to do anything.
But magically! I've just put my other (PAYG) O2 simcard and the internet now works! However, still not as good as before. (Slightly laggy)
I was using Darkys 9.3 when the internet stopped working properly, so I upgraded to 9.5 hoping that it would fix the problem, but no help.
Since that it's working now. It seems internet connections is slower than when I had 9.3. Well, at least it works now. (Kind of)

[Q] No reception whatsoever!

I'm having this weird issue with my galaxy s. The weird part is that over the last couple of weeks, reception has been zero in a period of time that's been steadily increasing. I've been able to restart the phone to fix it, until yesterday when I couldn't get any reception at all.
But wait, there's more! My sim card works in my girlfriends gs2, her sim card works fine in mine. So, it's only the combination of my sim card and my phone that gives me no reception at all. Also, what could be causing reception to steadily degrade to the point of none at all?
I'm running the team icsgs rc 4.2 with semaphore kernel, but I couldn't post in that thread because of my low post count. So, what I'm thinking is that I should try another modem before I try to wipe and perhaps install another rom. My question is, do I have to use Odin to flash a new modem, or can I just use cwm? Anybody have a suggestion for a particular modem?

So, Ive flashed the KF1 nexus modem, no change at all..

The only thing I haven't tried now is going back to stock rom... Anyone?

I have problems with Nexus S modems (that are so popular last weeks). For me the best modem is original JVU (the CM version). Try with that modem (if not with it already).
Try with the original build, because that reminds me for a hardware problem. You can debug the problem with experiments. Try everything before going to service.

No EDGE/GPRS signal
Hi!
Because I cannot post in development section, I'm putting this here...
Last week I've tried 9 ROMs and different modems and the problem was always the same...
When I'm on UMTS/HSDPA signal, everything works great, but when I'm on EDGE/GPRS signal, I cannot even make a call, or send a message.
This problem is happening to me for the last two weeks... :-(
ROMs tried: teamhacksung's CM9 ALPHA for Galaxy S (BUILD 17, 16), Team ICSSGS RC4.2, AOKP Milestone 4, Build 28 (now using), Dark Knight 3, 4, Elite V9.0
Kernels: Semaphore ICS 0.9.5b, Devil Skorpion Kernel, Midnight ICS 0.9.0-2-HUGERAM (now using), and the ones which comes with ROMs
Modems: XXJVU, XXJVT, XXKF1, XXKD1, XXKB3, AUCKF1, XXJVK, XXJVO and now I'm using XXJW4
When I flash DarkyROM JVU-RE with Odin everything works fine. :-S
So.... I think the problem could be in the ICS ROMs or kernels
If anyone knows how to solve this problem with 2G networks, I would be very grateful.
p.s.
Also, I find my SGS very often bootloop without possibility to enter CWM when I'm flashing new ROM.
And I found a solution for those bootloops, because I'm tired of flashing with ODIN a new GB ROM constantly... after bootloop, I use FixRecovery and flash it with Odin, then enter CWM and install Team ISCSGS RC 4.2 which only starts and make boot image and flash new CWM, so I can flash other ICS ROMs...
Why I'm telling this? - only because the devs could see if they can make other ROMs to start with flashing like Team ICSSGS RC4.2.
Sorry for my bad English. :-$
Edit: @adytum
I have also thought that my SIM card was a problem, so I've exchanged it. Didn't help....
At first the problem was like yours...

Will attempt to install the original stock firmware today (boooo, downgrading from ICS ), but I have my doubts. My service provider have started technical problemshooting at their end, but I have my doubts there too.
To add to the confusion, I discovered that 3g and data traffic works fine, wireless works fine, but calling doesnt work at all. As mentioned, if I put my sim in an other phone, or another sim in my phone, it always works.

I just managed to make it work. In test settings, INFO part (*#*#4636#*#*), after 5 times setting WCDMA only, my phone works only on 3G networks and now I can communicate because it doesn't switch to 2G...
But, I would appreciate if anyone find out solution for problem with 2G.
I hope that this isn't problem with my phone.
As far as your problem, I would try to reinstal the modem, because after trying a lot of new ones, sometimes it just doesn't recognise which one is instaled. JW4 seems the best for me...
Sorry for my bad English... :-(

Here is link where you can get JW4 modem. Flash it through CWM, reboot and check if that will help.

If I could hug you, I would! This modem seems to have solved all my issues! So, yes, our problems are probably related to eachother and to ICS. Never got around to try stock or darkys rom, but I'm guessing that would have fixed my signal issues too.
A million thanks to you! (Now I'm just crossing my fingers for stability and that this is not a fluke!)

Well, I'm glad to see that it works...
For me, JW4 have the best signal, and is very stable. And, you know, I've tried almost all other modems, and they were all pretty much the same.
I wouldn't tell you about that modem if I haven't seen that I have HSDPA reception (-95dBm) in the places where I had very poor 2G signal (-103dBm) , and no 3G signal (-111dBm) at all before.
Sorry for my bad English....

Have you tried if other sim cards work in your phone, or your sim card works in other phones? If so, I'm thinking that these issues have something to do with the service providers not being up to date regarding newer android versions. That's really the only logical conclusion I can draw.
I did call my service provider earlier today, they were as stumped as I am, but did suggest to try connecting with 2g and 3g enabled respectively.
By the way, your english is just fine

Well, I was working as tech support at my provider (until last month), so everything is fine with network and signal.
Also, first thing I did was to check SIM card and it is OK. I even exchange my SIM because it was 5 years old -just in case...
Everything works great in other phones, but in my phone only 2G network reception doesn't- even with other SIM cards...
That is very weird, but, I finally managed to set only 3G so, everything works now, but with very poor signal in places where I had EDGE coverage before.
I even thought that could be a problem with my device, but when I flash GB ROM, everything works, so I'm thinking that it only could be a bug in kernel or ROM.
I didn't see much people complaining about this, maybe only because they are constantly on 3G...
I don't know...

And...
Btw, service providers have nothing to update or upgrade with signal, because it is only frequencies they have to maintain and base cell as root. That's why we use SIM card which help our phones decode signal.
Only thing that is up to providers is maintaining the level of signal and its communication with central station, along with base overload in urban areas.
Sadly,
In 98% of problems, it is up to SIM card, device or software on it.
When the problem is up to service provider, everyone in that region- on the same base cells, have it. :-(
So, obviously it can only be ROM/kernel problem or device(hardware) problem. :-(((

Obviously the main difference here is that the only thing that ruined reception for me was the combination of my sim card and my phone, every other sim and phone combination worked.
You probably have more extensive knowledge about this than I do, and you're probably right inducing that it is a rom or kernel bug.

In that case, there are two options;
Maybe SIM card didn't set well, or SIM card is damaged.
You can try to see if it is damaged or has something on it and clean it. Otherwise, if it is damaged or just won't work, go and exchange it. It takes just a 5 min. And if you tell that SIM stopped working, they won't charge you anything. And, after that, you'll be sure that SIM works.
It also happened to me in the begining, and I was wondering why my SIM won't work only in my phone. Then, I place it in my old Nokia and after 2 days, I couldn't talk with people and the signal was OK. Then I exchanged it, and everything was OK.
Now, obviously I have a problem with a phone. :-(
Maybe it is a message to me to buy a new one... Note, maybe... ;-)
Anyway, I hope that I've helped you.

Seems I was a little too quick. Problems started again today, but I've managed to fix it for now..
I installed jvu from odin as per the first post in the elite, ICS beta 8 thread. Found that everything worked fine in jvu, and now it also works fine in ICS.

[Q] Yet Another wifi ICS issue

Hey peeps, ti me for my first post.
Well i upgraded tO stock germanICS a couple of days back. Everything was working fine until yesterday. WiFi is behaving weird, i can connect with no probs at home but i've noticed that the download arrow from the WiFi icon on status bar is on and off all the time, draining the battery faster than expected(e.g. rom 100% to 65% 3 hours almost no use). So i spoke with a friend of mine, kind of a geek, he told me it could be so me kind of compatibility issue between ICS and old router's firmware. So i went to a bar nearby to check if i could reproduce the same behaviour and everything was working normal.
Did Anyone here had anything similar? I've been surfing to do so me research, but all i've found is so me peoples probs with WiFi not connecting at all and some sII users withe their WiFi module broken.
Thanks in advance!

Also...
I´ve read somewhere that a factory wipe solved some wifi´s peoples probs. As i´m under german ICS LPY i know i´ll be likely bricking the note if i wipe, what leads to teh next question...is it possible to flash a kernell(without the bug) without being root?
Cheers,
VR
edit
So i´ve been reading quite some info about franco´s and speedmod´s kernels, and it´s so confusing for starters.My last question remains , is it possible to flash those for a non rooted device? Anyone that is running it tried wiping? Results?
Thx again
Edit 2
After some research i now know i need to root for any new kernel flash, as i read my post i´m starting to feel i´ve lost my head somewhere, so bear with me, hehehe. Also found out some people tried wiping with franco´s kernel with no probs, so i almost have the info i was looking for. So, in case i go root and get franco´s kernel up and running, do you think my WIFI issues might dissapear after wiping?

I have the same bug...with wifi also the os android buy draining ny battery so bad...im on stick rom gb 2.3.6 with the ssme oroblem....any solution?

[Q] HD7 Wifi Showing "No Networks"

Hi All,
Bought a HD7 off ebay, it was stuck on screen after HTC Logo. Its an o2 one. It booted fine after a full reset using both volume buttons+power. But that was after I opened it and took the memory card out etc... but it works now.
Problem is, I just spend another bit of cash to unlock it only to find the wifi is now not working, I never tried it before this, but I remember when it was stuck it showed a greyed out wifi logo (wifi available icon). Now no matter how close it is to my router, or many routers here it doesnt pick up anything.
Does it have anything to do with that sticker (grey one) over the memory card because that was getting in my way and I cut it, since I tried to stick it back to no avail.
Anyways its running :
HD7 T9292
Bootloader : 5.11.22
Radio : 5.71.09
OS : 7.10.8107.79 (UK o2)
I have hard reset it many times. 3g works but its also patchy sometimes it doesnt work.
I would like to know if there is a fix, or how I can install a fresh rom on it, like a custom one, or even the stock one to see if it works.
Many thanks in advance.
UPDATE :
I fixed the issue by taking out the 3g sim, then hard reset using both volume buttons + power, then let it set up fresh, then it picked up wifi networks. I re-inserted the sim and restarted again and now have both 3g + wifi. Very strange.
UPDATE 2 :
The wifi has gone again, I upgraded to tango, everything went smoothly but I dont have wifi anymore, and even after master resets its not coming back.
The cause could have been :
- Connecting it to the computer
- Updating the OS which made it restart a few times.
- Connecting it to the charger.
I do not know which one of the above it was. Still looking for any hints on how to resolve, since my main sim doesnt have 3g I am left without internet.
UPDATE 3 :
Downgraded the SPL using Y Cable, installed NextGen+ 3.3 and still no wifi... Then downgraded the radio to nodo, no wifi, but this morning turned the phone on and the "networks available" icon showed, but unable to pick any networks or connect. Infact now it has issues letting me into the wifi page.

Hey Muhammad A
Did you fix the problem with no networks found thinge?
That would be great help if u'd find it.
Cheers, mate

Same issue for me. Multiple hard resets and versions, no wifi or blueooth.

Same here it's an old phone from a friend.. Any solutions?? Is it a Hardware problem??

I too have the same issue
I too have the same issue
