Phone constantly on G instead of 3G since yesterday and also wifi doesn't connect!!

Hi guys,
Since yesterday morning my phone has been on G (edge/gprs) only instead of 3G (hsdpa) like it was almost always before. I'm on voda uk with good 3g signals in London and phone is showing -51 to -65 dBm (22-31 asu) which i think is good.
Also my wifi that always worked is also not connecting anymore...what gives? Regarding wifi i mean it connects but home page doesn't load any more on constantly refreshing even once. It does on my laptop on same wifi signal.
I have just updated normal apps like handcent sms/linda manager etc. since yesterday and restarted phone many times and done nothing drastic...so why these data problems all of a sudden?? Thanks
Carrier: Vodafone UK
Country / Language: English (UK)
OS / Browser / build number (if applicable): update 1 - stock rom

Tried soft reset by pulling out battery...on restart phone showed 3g for a second before wifi kicked in...still no page load...after switching off wifi it again went to G only!! Damn I don't wanna have to lose and reinstall all data/apps!! This so irritating..I love this fone and this is how it treats me!

Lunacy!
Now the fone automatically goes to 3G UMTS/HSDPA (wifi off) but with atrocious signal strengths of 0 dBm or -111 dBm with 1 or no bars!!!
I always get awesome signals in my room arnd -55 to -69 dBm and all 4 bars so what the hell is going on!!
Is this vodafone's issues or my N1 is dying slowly!?

Back to G n no wifi use!
Any help anyone?? please!

Not sure how to help you, but I thought I'd mention this if it's at all related:
my phone has twice now shown that it's on Edge connection, but run at 3G speeds. Not sure what the bug is but I ran a speedtest and was able to stream Pandora and browse the web without any trouble.

thanks for that but i'd sure love to see some pro's to help me out!

sounds like a carrier issue... however if you are rooted, try reflashing your radio and see if that helps and you may want to try each radio out as well

wifi is working today with full signal but on mobila data it stays on G with full signal but 3G sometimes with 1 bar or no signal...wtf!

When was the last time everything worked correctly? What have you do with your phone since then (different rom, different radio flash, new mods that alter system files, etc)? Have you tried calling your carrier to see if they are having problems in your region?

Nandroid backup, factory restore, reflsh cyanogen, test. If it works again you've got some bad setting stored. I can't help you find that setting but at least you've narrowed it down.

If this is affecting your wifi, then it's not a carrier issue. It's something with your phone.

2 days ago all was well. I just updated linda manager/handcent sms and 1-2 apps from market. I'm on stock rom so no radio etc. for me and I don't mess with system files and keep my phone clean by clearing caches etc. Thanks anyway.

I suppose so...but this is quite odd considering all worked super before and I haven't done anything! Stock rom!

Do a factory reset or a full wipe through recovery. If that doesn't resolve the issue, then let us know.

Question about flashing Thailands firmware on Canadian Milestone

I know they use the same frequencies as Telus so all my data should work and I will get all the bug fixes from the Thai firmware, but before I do it I just wanted to know if I am going to have any localization problems like:
default language from using the firmware.
Any hard coded info like servers (I read a tutorial once about using a unlocked MIlestone on Bell and having to root it to get assisted gps working by changing the server info 3 times in different files) so that is a example of info I would like to know before hand. Or does that info along with APNs get saved in a area the service does not touch.
I assume my apps will be fine since I am using a service version.

I have the 2.36 Thai version running on mine, while still running on Telus. I haven't modded the location file yet, and the GPS works just fine Language is still in English.

Good to know about the language. I know GPS would still work since the servers I was talking about are just for the assisted part I think speeding it up when finding you.
Did you have to manually set any APN settings after flashing the Thai version.

Has this happened to anyone?
I did the upgrade then shortly after I got a notification that I lost data connectivity due to data roaming. Which I wasn't. I had to reboot to get data working again.

It kept happening until I gave up and decided I would rather have random music playing then having to reboot or go in and out of airplane mode everytime I wanted to go online.
It would be interesting to know why this is happening though. I am in a big city and it was happening at work and home.

Does the Thai firmware have some sort of advantage to other firmwares?

@ shadowofdarkness: You could have just turned on the data roaming. Though the phone may think it's roaming, your carrier won't.
@ bemymonkey: I find it quicker just in general, but that may just be me. I found when I was using the Telus release it felt very bogged down and laggy. I ran some tests with a buddy of mine (he running stock Telus, me running stock Thai) and it showed that mine was running about 1/5th faster on most tasks.

At the time the Thai version had bug fixes I wanted but since then GOT released a new Telus version with the same fixes.

Interesting... if I get bored I might try it

JK3 modem, loss of all reception, drains battery, requires a reboot

So, right now I am using the Axura RC1 CE (I will update later), but I have had the problem described in the topic on various other ROMs using the JK3 modem.
It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
Anyone else experiencing this on ATTs network, or if there is a fix, I spent the last hour searching and going through the various threads to no avail (or I just suck at searching)..

Did you try the Axura thread?

I'm having the same issue but I've tried Assonance as well and still get the random no service. Tried different i9000 modems as well--anyone know if its safe to use a captivate modem??? I'm guessing no but just want to know if anyone has tried it without borking the phone.

I'm having this same issue as well, that's why I've tried to stay away from the UGJK3 modem, however, it's seems every custom ROM is starting to use it
As far as using a captivate modem with an i9000 ROM, I've tried that also, while it didn't totally brick my phone, I did get random FCs. I've read that is a dangerous path to go down.

I feel the same way. I might try the CogKernel and see if that helps...

Please, please, PLEASE do not post these types of things in Development.

+1 Lets keep this forum area clean .. its just for development stuff guys.

I have had the same issue with all I9000 modems, the only fix that has worked for me is to enter the service menu and force WCDMA 850 Band only. Also, questions should be posted in the question forum.

[this thread is pretty relevant to development - considering the rom chefs are using this modem in their releases and it has a potential major flaw. if the mods find it better to be in Q&A, then please move it - otherwise, i think the right eyes will see it here]
yes, yes and yes!
ive been posting about it in the perception thread, but no one (save for 1 user) chimed in with the same issue.
we both noticed that we both have an issue where we will bounce from 3G to H and back fairly often. this leads me to believe that it could be part of the problem.
i just odin'ed back to stock because my phone isnt receiving incoming calls now.
what i had planned to do was flash the latest perception but use a different modem... but it seems like the only sensible modem is the JK3 (although there is word on the street a new one just leaked?). so that idea is kind of out.
someone here said they were going to try cogkernel2, but i was on setirons and cogkernel2 and it happened with both. it seems to be a modem issue.
i wanted to lock the phone to use 3G only to see if that would help, but no one shared a way how... but reading this post it seems i can do it from the service menu - though i dont know exactly what to set/change to keep it only on 3G. (any help would be great).
so i believe im going to flash perception 8 and see if i can lock it into 3g mode and go from there. this is getting pretty tiring. im hoping if a new modem releases that will help, but i honestly am not sure i can wait since it is making the phone unusable.
below are my posts from the perception thread on the issue.

i searched but did not find...
i see others have had issues with APN force closing. i do as well, but assuming that isnt a problem, i dont mind.
my issue is that after a certain period of time left asleep, my phone will completely fall off the network. changing flight and data mode dont work, nor help. a restart works. this has started a day or two ago, but was not an issue for the first week (give or take). if it is relevant, my network constantly swaps between H and 3G where i live.
i have not found a setting to force 3g (and disable hsdpa) as i figured it was the network hopping that was doing it. am i just missing that setting? anyone else with this issue? (again, i saw people with the apn force close but not complete loss of network unrelated to initial flash)
also, i think that each build should get its own thread. it is VERY difficult to find accurate information on the current build once a thread has 4 builds and 250 pages in it. even with search, it would still be a good idea.
thanks and thanks.

anyone having this issue or have any ideas?
of note: going into wifi settings is also borked. it will eventually time out and FC. i also think that the times my phone has completely lost network and not reconnected have happened more often when charging. but that could be coincidence.

this continued the same way on perception7 with cogkernel2. no real difference.

in relation to my post below yours, does locking the 850 band only force the phone to use only 3G, or is HSDPA/HSUPA still enabled but you found the 850 band to be more stable.
this is what my next attempt will be to get a solid platform going.

I've tried different modems other than jk3 and it doesn't fix the problem. Stinks that you've used Cogkernel2 and it doesn't help. I also tried the different band selection in service mode and it also hasn't help me (apparently this worked for some people). If you want to give it a shot do the following:
1. Dial *#0011#
2. menu button then soft back key
3. then phone control -> network control -> band selection
4. good luck!

ugh. that is disheartening. i will try the band lock, thanks.
can you confirm or deny that when you notice your phone goes completely out of service that it has been hopping between 3G and H? it would be interesting to see if we all have that issue as part of it.
also, fingers crossed for that supposed new modem.
/sigh

Yeah this really sucks because these roms are great with this one very big exception. I haven't noticed the hoping before I need to reboot. I have noticed that if I switch into airplane mode once I drop service I can't turn it off.

I had the same issues with Axura and Percetion. I found that switching my network control to WCDMA 1900 only pretty much fixed it. The only problem I had after was that any time I lost service naturally, ie, bad area, or shielded rooms, whenever I came back into a good service area I could never get a signal again. So I would have to reboot.
In the end, I'm back on Cog, 2.3b7 and no issues for about 14 hours now.

I'm using the non oc. I'm not gaming or doing anything too wild with my phone so non is just fine for me.

hmmm, makes me think that's the issue then. most of these roms have kernels that have the oc feature.

hey keener, did you have the oc version of cog?

Weak signal after radio and ROM flash

After the most recent stock update that added Sense 3 I started having intermittent radio problems. I had always been on stock and never fiddled with the firmware, radio, anything like that. The radio would randomly disconnect from the network and stay disconnected for a while, or I could get it back faster if I rebooted the phone or cycled flight mode. Using data often acted as a catalyst for the problem and I could reduce occurrences by using wifi when I'm at home. Total annoyance. I decided to try fixing it myself and I've found a lot of useful information here.
I first installed a couple different ROMs and found that after booting, there was no signal, so it was probably the radio. I had HBOOT 2.0 so I had to downgrade, use Revolutionary to get S-OFF, then start working with different radio versions. I haven't had any luck since.
Current setup:
Bought unbranded and unlocked from the UK. 900/1700/2100 model
Revolutionary HBOOT-6.13.1002
Baseband: 20.4802.30.0882U_3882.10.08.28_M
ROM: Virtuous Quattro RC2 (Android 4.0.2)
Network: 3 Sweden (UMTS 900/1200 network)
I've also had the same problem running Cyanogen 7.1 and Android Revolution HD 2.1.3. I had high hopes for ARHD since it said it specifically was designed for the radio I've flashed. I actually even went through and tried every single radio release from Gingerbread for the IncS. Same problem on all.
Strictly speaking it's not actually a no-signal problem, it's a very weak/malfunctioning signal problem. When I do a network scan I usually only see two of the three GSM networks here and most if not all 3G networks are missing. The few times my home network has actually shown up in the network scan list, I can't register on it. I get the "Temporarily unable to register on this network. Try again later." message.
I hope I've done enough searching and effort on my own here before posting. Needless to say I'll be grateful for any help I can get here. After many hours of reading, flashing, rebooting, reflashing, rinse and repeat, I'm looking for an end to this!

Remember to close your back cover after each radio flash so you will get much accurate result.

wow..i was having the same problem. totally forgot about the antenna in the back cover. i was going nuts flashing different radios wondering why i was getting only edge. i feel stupid. thanks

I had no idea the back cover made any difference at all. Thank you for pointing that out to me! I was seriously about to go buy an iPhone or something, but I remembered I loathe the keyboard in iOS
I'm all good now! Running radio .28_M with ICS and things are as they should be. At least throughout all this hassle I got my radio upgraded to a hopefully less-crashy version and I got some ICS up and running
Cheers guys!

[Q] SMS fails often, 3G says it's on but doesn't work

Phone Specs:
LG Optimus 4X HD International
T-Mobile US $30 Prepaid unlimited data/text 100 min talk
Android Version 4.0.3
Kernel version 2.6.3.4
Software Version LG-P880-V10e-OCT-16-2012 (can't figure out how to update but that's a different subject)
Signal strength is ~ -95dBm
Mobile network type UMTS:3 or HSPA:11
Ping IPAddr: Fail: IP addr not reachable
Ping Hostname(www.google.com): Pass (usually)
HTTP Client test: Fail: Code: [email protected]
Problem:
SMS/MMS often times is not working (send or recieve). Powering off/on will fix it sometimes, but not always. This happens both at home and at school. On days this happens the battery drains really fast (100% - 9% in ~10hrs). I checked the SMSC using a different phone (LG shows Update/Refresh error) and it is +12063130004. This has been happening on and off, but I switched from stock Messenger app to Textra and it seemed to fix it for ~a month. Turning on SMS over IMS helps, until 3G craps out. It displays 3G in the corner and the signal is still good, but no internet will load. Also calls will not send(occasionally). Any help is appreciated. If you need more phone info to troubleshoot I can try to find it.

it's tough to troubleshoot that, since almost noone is on ics anymore. i personally only had it for two weeks before flashing leaked jellybean. an obvious suggestion, but do try to update to jellybean. you can always roll back to ics if you really want to. a useful guide for upgrading to jellybean can be found here:

try switching to another usb port on your computer, or try another computer completely. flashing a kdz didn't erase the data, if i recall correctly, but it would be prudent to do full factory reset after the upgrade.

Got it off amazon. My sister got the exact same phone from the same seller with the same plan and hasn't had any issues. Could the Sim be damaged or something like that?

In my experience a worn out simcard does affect reception, so if you think it has been a while getting a new one should do no harm
But also you should try and get your hands on the us version of the software rather thatn european, that might also help

Its been under a year since I got the Sim. I just factory reset to see if an app is causing my issues cause I haven't always had this issue on in this phone. I'll try it for a week and see what happens. Also there is no US version because this phone was never offered on the US market. Hence Amazon purchase and Euro Open software
