Hi there, my atrix drops the connection to my operator a few times a day
Switching from 3g to 2g isn't a problem, but as said sometimes it drops completely saying "network with limited service found " and "your sim doesn't allow a connection to this network"
Does anyone knows help?

You're not close to the border or something? It sounds like you don't have your network choice on automatic so when you go out of your provider's coverage area your phone doesn't connect. Try putting the "Operator selection" on automatic

i have Network selection on automatic!
and it works fine until I get completely kicked out. really works with switch between 2g and 3g + data...
I get an cross at the network signal strenght and an error when I retry to login...
I have completely no idea what's wrong, my operator says they don't support until they sell the Moto official with contract...
I flashed back to from 83 to 52 but still the same.
unlocked by vendor At&T atrix with root and activated sideload with an Europe sim

I don't understand how you flashed there but you should flash the 1.2.6 SBF and then do the OTA updates.

I flashed the signed sbf with rsd lite.
1.8.3 ota from which I flashed still got the same problem

No clue then. I'm using it in Germany, also sim-unlocked, without any problems..

Right I got me a bit of an issue.
Dunno if it's been covered by someone already, but there's only so much the search bar can do from my phone.
I am using X10i I am on O2-uk
Even when I am sat next to someone that has full 3G signal, I am totally unable to get anything.
I've had this phone for just a year now an idea have never had a 3G signal. The best I can do is get H
The status bar claims to have 3G bit as soon as I try an use the connection, for ANY reason, it instantly switches back over to H
So basically my issue is........ WTF!?!?
Why not ant I connect to through 3G? And does anyone else have this problem? Is there fix for it? An app or something I'm missing?

The infamous "H" ...
From what I understand H is better than 3G...in fact its 3.5G! Increased download speeds when compared to regular 3G..
"H"is a good thing..
Sent from my X10 using XDA App
Really? If that's the case then I should have seen 3G at some point in the last year when I had worse signal???
Sent from my X10i using XDA App
Nope. Afaik 3g depends on availability in your area. Not related to signal strength.
Sent from my X10 using XDA App
Yeah mate the h is for hsdpa which is, as said above, better than 3g.
Edit: if phone can't get hsdpa it will go for 3g. If it can't get 3g it will search for edge (will just have an e). If it can't get e then u need to stop living on mars as u ain't got no mobile internet.
Sent from my X10i using XDA App
You can't really complain some people have issues even getting 2g while your having 3.5g
Sent from my X10i using xda premium
Ok
Thanks guys. I was under the impression 3G was better than H
Cheers for clearing that up

I'm not sure if there is a fix for this. Update the PRL and your profile. If the problem is still occurring it may just be a problem with the service itself.
There are multiple threads on this here in this section.. go into settings, click on mobile network, and change CDMA/LTE to just CDMA and see if that helps, I have had the same issue but haven't had the chance to test this out yet

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

LFB is a poor modem firmware .

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

Washington D.C. has no GSM coverage inside the tunnels. Only some stations have coverage. Only Verizon and Sprint with CDMA devices have service on moving trains.

You can flash DXLF3.. It works so much better than the LFB radio.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...
Got a problem , hope you guys can help.
My my mobile data won't work on anything less than HCDMA, but when I set this my phone signal drops to 1 bar or less!
If I set it to gsm my signal goes full but no data!
I have rooted and installed a insecure kernel /rom as below .... worked fine for a few months.

Android version : 4.0.4

Is there a chance you are on 3 UK?
Afaik, as their name indicates, they only provide 3G/HSPA coverage and no 2G coverage.
3G uses higher frequencies which means more throughput but less distance so it's normal that the signal is weaker than when using 2G networks.
It's also less resiliant to distortion and other signal issues.
You might want to check into using a 3G repeater if the issue occurs at home but be warned that the usage of these devices is shady at best and illegal in most countries. (You'd need an official license to broadcast at that spectrum even if it never reaches across your own borders)

Hi! Flashing a modem might help you out on that problem.

no problem. do leave a feedback!
kernels are for wifi connections
modems are for network connections like your signal
Try calling your carrier and ask them to refresh your network and APN setting. I suffered this problem yesterday and called my carrier five times to deal with it. Now it is running fine.
Sent from my GT-I9300 using xda app-developers app
Thanks guys for both of your suggestions, I did change my modem and I did ring Vodafone to refresh.
The modem did improve the signal slightly but the refresh has resumed normal service!
At least I now know how to change or tweak my modem for optimum performance. Also did not know the kernel was for WiFi.....will look at that too!

One strange thing though...only works on edge....anything higher it just hangs.
Sent from my GT-I9300 using xda app-developers app
As i find and as others have posted .
If you have changed modems and get problems after reflash to a known good modem .
Then one solution is to start from scratch wipe phone and install older stock firmware .
Then update .

You are most welcome
