Data Connection

I seem to be having some problem with my HSDPA connection on my desire. I'm wih Three UK and I can't tell is it is my network on the phone.
What happened is for some reason it just wont work anywhere I go. For the first few weeks its worked fine and then towards the end of last month they sent me texts saying they would cut my internet off if I carry on using it but I can't see that having anything to do with it as it is a new month.
The phone is rooted and I've flash the new DeFrOsT Rom (2.0a) and it started working again but then when I logged into the Facebook app it stopped working and went to R (also the wholetime I'm connected to a wifi and when I disconnect from wifi I still get the no connection).
I tried uninstalling Facebook and logging out and no luck
I was wondering if anyone had any experience with this or it is happening to them or you know a fix.
I also attached some screenshots of the message I get, I can't actually read the full message as it cuts it off and then when you select it, it just takes you to the homepage.

the R is for roaming
how is the signal strength where you're located?
go into settings -> wireless and networks ->
tell me what roaming settings you have enabled
untick the box to allow data roaming
data roaming will take place when the signal strength is very low and you are therefore using other carrier's networks (this might also incur high data costs!)

Data roaming is disabled and the signal in my area is usually quite good. Also when I go into a city around here or anywhere nothing changes it still sticks on R.
Plus before I started to flash it with roms and rooted it, it would nearly always have HSDPA connection.

so although data roaming is disabled your phone is roaming...
can i ask why it is that 3 told you that they will disable your internet? this seems to be the main problem...
have you tried flashing a different radio?
this will definitely have some change

They sent a text I was reaching/reached my data allowance for the month (so called unlimited =/)
And yeah I've just flashed the new radio that is needed for defrost 2.0a however it did happen before I flashed it.
For some reason it has got proper signal and HSDPA for the time being and as far as I know I did nothing to make it any better.
Got a feeling it will go again but I'll keep you updated.
I'll have to ring three up tomorrow if I can't get it sorted as I'm going on holiday and I'll be screwed with out it,

sounds to me like you have a data cap where if you exceed a certain limit your internet is stopped.
the fact that you are in roaming makes me think that it is a trick so that 3 can charge you large amounts so be careful.
glad the radio update worked for you
let us know if the problem persists
although there's not much we can do unless we know it's been sorted with your provider.

Thanks for the help.
The thing I don't get is the roaming bit as when it says I'm roaming I can make calls and text fine and there is no charge or anything on my bill it just uses normal minutes

honestly it sounds to me like a problem with your provider
does it still say roaming with the new radio?
if it does then phone your provider because they can charge you a large amount for roaming

Three only run a 3G network in the UK. To provide coverage and data connectivity (mainly EDGE) in the areas between their masts they partner with Orange. Your Desire will roam onto the Orange (and possibly now T-Mobile since they merged on Monday) network when it has a weak or no 3G signal. To allow data in these circumstances you must have data when roaming enabled.
There is no additional charge for 3 customers to use data roaming while in the UK. It is part of your monthly bundle. However, please remember to turn data roaming back off when you travel abroad or it'll cost you a fortune!

+1 for the above, roaming is all well and good but of you leave it on when your on holiday youll definately remember it!

Thanks I didn't realise I could use data roaming as when I clicked to enable it it said I may be charged so I didn't bother but now I will as I wont get charged
I was just about to say that the original problem had gone but it's decided to happen again just as I tried to log into ebay and download something from the market. However I think it has started to use data roaming as there is now an R in the signal box but a G next to it where the H would be.
Think I'll be ringing them up today

[Q] Data Problems on EDGE?

Anybody Having Data Issues, Like Being Stuck On Edge Outside And Inside Of Your House? Weird Data Switching All The Time? If So Did You Find Any Fixes Cause I Am Having That Problem On Every Rom From Stock To Juggernaut...
Edit : I Would Fill Out The Form To Samsung But Why Do It Unless Everyone Else Is Having The Problem To...

my issues is unstable 4g connection. it would just time out and not come back on until i turn on/off flight mode or just reboot.
manually switching to EDGE works just fine for me. idk my SGS2 is doing this.
vibrant: speeds and connection were fine until i cracked the screen
g1:used my g1 for 3 days before i purchased my SGS2. again, speeds and connection were fine
SGS2: 4g connection time out.
not even close to throttled and i mostly use my heavy data usage while at home.
TIP:
1) change your sim card
2)call tmobile (dial 611 on your phone)
- ask for technical support
- ask them to reset the network in your area.

The Weird Thing Is Stays On Edge But Gives Off Better Reception Bars, I Dunno If Some How The Modem Settings Is Backwards... Plus I Havent Even Used Half Of My Data
Edit: It Went Back On

Data drop after changing data source

After having my Galaxy Nexus for a few weeks I'd like to share my experiences with 'possible' data connectivity issues.
Firstly,
Upon first activating my phone at an official Verizon store I noticed that I lost data and voice services for almost 20 minutes after the phone was first activated. Toggling of 3G/4G, Airplane mode, and even rebooting (battery pull) would not fix the problem... It eventually just started working and has been fairly reliable ever since.
On the second day of owning the phone I unlocked / rooted... Still using the stock rom, antenna, and kernel though.
Secondly,
I've started to notice that every time I switch data sources.... For instance
*Turning off Wifi when connected to an AP
*Turning off 4G services
I'll completely lose data connectivity for a period of seconds; no longer than a minute (all gray reception bars). However, I can still make calls and send texts. My question is, is this behavior normal for the device? I've never owned a 4G device before so I'm ignorant to the matter. I'm simply inquiring as if this is a sign of a faulty antenna VZW is going to owe me a brand new device (not some refurbished crap either...). If this is typical, then I suppose it's just the nature of the beast. Either way, I've love to hear from others regarding their experiences.... Thanks!
Regards,
-Doug

When I had the thunderbolt data would drop in and out when switching from 3/4G and from wifi.

when you are switching from wifi to 4g/3g, it has to change your IP address, as its a different network. 4g to 3g viceversa it has to switch what frequency it is talking on, and reestablish communication with your carrier. switching data source will always drop data during the switch.
some later software upgrades have, and will reduce the time between switches, but there will always be some form of drop

Why data connection lost and why reboot fixed it?

Hi,
Using GNex, stock JB 4.11, Wind Mobile Canada, $40 plan, unlimited data & Canada wide.
Please excuse in advance for the novice questions. I am not yet familiar with Wind Mobile. The customer support is too long and submitting a question to their website required around 5 days to get an answer which is generally irrelevant in my short experience. Hope some expert users here can share some of your knowledge.
Last week, suddenly during a phone conversation, the phone became totally disconnected voice & data. The next morning, the situation didn't improve, so I rebooted the phone (power off / on). Then the phone could connect to voice, but no data (gray icon instead of blue). I stayed with no data for 3 days. During that time, I tried a few reboots, changing various network settings (APN, Network Operators, Data roaming, etc.). None of that worked, then I made another reboot and suddenly everything is back to normal (no roaming and data OK).
Q1. Signal strength variation: what is the cause that makes a signal vary? For the same location, sometimes signal changes from 3 bars to 1 within a few minutes.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data). I purposely disabled roaming, I admit a network could have some issues, but I have hard time to admit that a disruption could last 12 hours. May be the issue is my phone? It was not rebooted since 7 days.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Thanks in advance for any help.

Welcome to the Nexus and its crap radio. Try turning off 4G, once I did that I never lost signal again. With 4G on I get disconnected from the network randomly throughout the day

How to turn off 4G? Wind Mobile operates on AWS network 1700/2100 MHz (UMTS band 4), and HSPA+ for data. I believe it is not 4G. On the phone Network Settings, there is only an option "Use only 2G Network" which is not a good option for me. If I enabled "Use only 2G Network" the phone shuts off data and changes to roaming mode.

just set ur nexus on airplane mode for a second..
then disable the airplane mode instantly..
u ll gain ur net working widout reboot... )

Oh wow, that's a cool tips.
I hope someone can answers my other questions, I like to understand the "how things works" side.

Any number of influences. A microwave, air ionization, temperature, humidity, output from the tower not consistant, and plus just the variations of the phone. Going by bars is a bad way to gauge anyways, it could have only dropped signal for a split second but it doesnt update the bars frequently so it would appear to be low signal longer than it could have actually been. Your phone works by line of sight, picture a tight wire from your phone to the tower, anything that crosses in that line reduces signal.

That actually is hard to answer, you would need to contact your provider to see if they have a log of an outage at that time before going into whether it was the phone or not.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Never unless things act funny. A reboot is usually healthy for operating systems (i know many do not). I personally don't intentionally reboot mine, it usually happens because I'm screwing with clock speeds
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Like any software there are chance of a 'glitch' where the modem and the driver have issues communicating. Toggling airplane mode off and then back on re-initializes this and in most cases fixes the communication problem. Rebooting will have the same effect. I would only worry if you are needing to do this often.

Hope this helps a little.
I would also contact your provider. They may have an issue with the tower you are connecting to.

Perfectly understood, appreciated very much your detailed answers. Can you please clarify below?

Makes sense. Indeed, when I said "For the same location, sometimes signal changes from 3 bars to 1 within a few minutes". Actually, I mean a room and I was walking/moving so may be the orientation of the phone explained why the reception was inconstant.
Regarding your answer above output from the tower not consistant. Is it possible that the tower reduces its signal strength when the number of users increases? Similar to users sharing a finite band width?

Yes, even orientation of the phone can have an affect, depends how the antenna is set up inside the phone, i havent seen it so i have no answer for that.
ya, as you move around you could have been what blocked the direct sight of the tower, signal passes through nonmetal objects but each time it does, it loses strength depending what it passes through

@OP I also have the same problem, I am also with Wind and had to do force reboot to make it reboot.

Flash the UGLC1 radio to your nexus. I'm with Wind as well and that radio gets me good service!

[Q] Slow/buggy/poor data connection and reception

I was originally a Verizon user so I'm not used to this kind of weak connection.
I had my phone replaced already due to another issue a few weeks ago
so I don't want to get another replacement because of this. it is really annoying!
Instead I will ask here and see if anyone could help !
**This has nothing to do with WiFi (because WiFi works great!)**
**And nothing to do with calls because call quality and connection showed no problems**
**Not exactly sure this problem started, just started getting annoyed with it recently**
\- What my phone is doing (when I'm at home) -/
1. Slow transition from WiFi connection
- When I turn Wifi off, I don't get an immediate data reception. Instead it takes about 10 seconds and then I barely start to get 3g..... not lte .... (It's not like this in every place)
2. Not much LTE
- It happens really rarely, most of the time at home the connection is on 3g
3. Lose data connection even while in use
- It's just sometimes unstable. When I'm browsing the web (while in 3g) it would sometimes go down to no bars at all and lose internet connectivity, then the 3g and I have to wait again until it comes back.
- Data roaming automatically turns on saying that I lost connection -_-
4. 3g is sometimes really unresponsive
- Just like when it is when turning off Wifi
- 3g would stay idle for sometime, even when I open apps that require internet
- Sometimes the 3g just disappears and decides not to comeback for a while
5. Bars up and down (drains battery?)
- I see this too often, like in every hour. While in 3g, the bars get suddenly full, then in an instant it drops to 1, then to 2. Then sometimes to no bars at all.
* in LTE it never gets like this, just constantly 1 bar
6. Maybe it's where I live?
- Possibly, but it's quite an urban and Sprint should have no problem covering this area in my opinion
- Verizon wasn't like this (although not perfect)
7. This is annoying
-Because it is draining the battery -_-
-Because my sister's iPhone 6 performs better (always has 2~3 bars) & my brother's S6 (though relatively weaker than her's) does not seem to lose connection compared mine at home (We're all Sprint users)
\- What I've done to confront this problem -/
1) Called Sprint, but didn't help at all. They told me to just take it to the store and have them take a look -__- Agent hardly knew anything...
2) Flashed Stock ROM and hard reset the phone (so annoying since you have to set things up again)
3) Made sure I set mobile data Network Mode to 'AUTOMATIC'
4) Made sure I have the latest Software version and have the PRL and Profile updated
But still no result at this point.
***Could this be a hardware issue? Or a software issue that is fixable?***
Can anyone give me some advice on how to fix this?
I mean it's just that the data reception is too weak an unreliable to think this is okay.
Right now my phone is pretty empty, barely any apps because of the reset.
I really don't want to believe it's due to a faulty hardware!
P.S. Possibly symptom?
The first day I got this phone as a replacement out of the store, I was unable to connect to the internet using data, even though calling was working.
What it was doing was, constantly switching from 3g - lte - inactive 3g - nothing - 3g - so on in a 20 second cycle.
By the end of that day towards midnight it was connecting to the internet.

Welcome to Sprint -_____- my GF has 4G LTE on Verizon where I live and I don't even have 3G, I roam on Verizon actually lol. Sprint literally has ZERO coverage while Verizon has LTE.. It's just Sprint dude lol.
