[Q] Have you experienced the data connectivity bug?

I want to know how many people have problems with the data connectivity bug. Normally data connectivity is lost completely or starts to creep after extensive use of bluetooth streaming, use of wifi, turning wifi on/off, after regaining cell signal after complete signal loss e.g. in underground garages or tunnels. Changing APN or toggling airplane mode let the arrows under the data symbol completely disappear. Only fix at the moment is to reboot.

I have the issue, it's the *only* issue I've had with my Atrix (SF Bay Area AT&T). Turning wifi/airplane mode on/off doesn't do the trick for me, only a restart. It's weird because my status will show that the signal strength is perfectly fine and that the "Mobile network type" is "HSDPA" , but the "Mobile Network State" will remain as "disconnected".
The battery manager shows the "Cell standby" numbers, and I believe that "Mobile Network State" impacts the "Time without a signal" percentage. I've gotten that percentage to be as high as 25% before after having the phone unplugged for 12 hours (3 hours without a data connection!!!).
I know it's not a network issue because I came from an iPhone 3g, which could successfully recover after losing a data connection in the same circumstances. I hope somebody fixes this soon

I've had it, only way to fix it is reboot for me

It became really quiet about this problem. I wonder if the people become used to reboot the phone once a day or if there are other workarounds....for me so far only rebooting the phone helps...

I lose data when I go into the Market. An error message pops up that says "A network error has occured. Retry, or cancel and return to the previous screen."

HTC Surround 3G Switch missing

Hi, does anyone know why on earth did HTC disable the 3G Switch for HTC Surround?? I have this phone, updated to Mango and the 3G Switch is missing from the Network Settings. I cannot understand this stupid idea of not letting the user decide what band to use his phone on.

RE: Solved
I have solved this.
This is available for every HTC Device which does not have the 3G Switch available:
Enter the Field Test Menu by dialing ##3282#, on the lower right side there are three dots: ... , enter that menu and there you can choose the band to work on: Automatic, 2G only, 3G only.

Sounds like a solution, but each time I change the setting from 3G to 2G or Automatic, and then go back into settings, it reverts back to 3G only. And the 3G icon remains at the top of the screen. So is your experience different. Been trying to disable 3G since December.

Do not set to auto,
Set it only to 2G, go back in the field test main menu with the back arrow <-, and then again in the ... menu, 2g should be still selected, and then <- twice to exit.

Gave it another try, but not so sure.
Went in to menu, set to 2G and then back arrow <-. Went back in ... and 2G was still selected, but after exiting <- <-, and going back in, 3G is selected again. Also my phone still shows 3G at the top of the screen, but I will admit that the signal strength appears to maybe be 1 bar higher. So, am I on 2G although the 3G icon still shows?
Guess I will know tomorrow after a full day of use hopefully at 2G, with reduced battery drain. I have a great WiFi signal at home and at work, so basically 90% of my day. The only thing data does is load email in the background and the occasional need for a connection if I stop somewhere on the way home. My 3G signal is typically 1 to 3 bars, averaging 2. And almost never higher than 3.
I have an unlimited data plan, but my WiFi speeds are generally 3 to 4 times better, and my experience has show very little difference in battery drain with WiFi on/off. No idea why AT&T would prevent me from using 2G, especially with Unlimited. iPhone users should be thanking me for the extra bandwidth I am offering.
Btw, I will absolutely NOT purchase a new phone with 4G/LTE whatever, unless I can turn it off.

[Q] Unable to switch mobile network

Is it possible that the Franco kernel can cause the phone to search for network infinitely? I mean when I am in menu > wireless & networks > mobile networks. It will just keep searching and won't stop to let me choose which to connect to which is annoying because EE has T-mobile and Orange; the latter is horrid and slow even with full 3G signal. For some reason the phone is stuck just connecting to EE Orange when normally if I go into aeroplane and out it will connect to EE T-mobile as it has the stronger signal. Or is it something that's wrong?

Try punching *#*#4636#*#* into the phone dialer and scroll down to the bottom. Just above the buttons at the botton on the screen should be a drop down menu displaying which network connection you are currently accessing. Press on that to open up the menu from here you can force your network preferences ( this is the area where you can also take advantage of the n4 dormant lte capabilities, but be aware this will increase battery usage) try locating the network you wish to be on and press it, give it a couple seconds is should disable the current one and a moment later as long as it is available should connect to your choice. Not sure if this helps in anyway but it is always fun to mess around with as many setting as you can never knowing which one will solve your problem.

T-mobile 3g/H+ switch delay/lag

I have a lag that takes 3~5 seconds for data to connect.
I am using PTEL, which rides on T-Mobile network.
The symptom is that, when I am Tmobile 3G/HSPA and trying to connect to internet from cold, I have to wait 3~5 seconds.
When the phone is idle, the icon stays "H". When I am trying to pull data, it takes a moment to change to "H+" and starts to pull data.
For example, when I open an article, I have to wait 3 seconds to connect to H+.
After finish reading it and try to load another article, I have to wait again to connect to H+.
My friend has Verizon LTE and when I use her phone, I am amazed how quickly I can browse through just like when I am on my computer with strong WIFI.
This is annoying and makes the battery drain.
On wifi, Nexus 4 can idle for hours and only lose 1% per hour.
But when it is on 3g, even when it is idling, it loses 10% per hour.
I think this 3g/HSPA lag causes the phone to be awake longer then needed to sync data.
I notice this because, sometimes the phone hangs forever waiting for data pull.
In that case I had to exit out of an app and go to chrome and try to access any website.
That helps other apps connecting to internet.
It seems that when I search about this connection lag, most of them have T-mobile.
I am wondering if anyone had similar issue and found a solution for this?
Is this also happening for folks who have Tmo LTE?
By the way, I am using Nexus5Experience rom and have left network configuration default.
I have apn that PTEL recommends which is "wholesale".
I tried "fast.t-mobile.com" and "epc.tmobile.com" and both have worst result than "wholesale" apn.
Thanks,

Refresh network (operators)

I'm using a provider which offers national roaming. This means if my network provider (let's name it A) doesn't have a (good) signal, phone switches to another network provider B (for which they have a contract). While on network B, I can call, SMS without limitation, but I'm limited to EDGE while using the mobile network.
It works ok, but there are some cases when I wish to change network faster.
For example - I came to the shopping center and in one part of it, the phone loses signal with my network provider A. It switches to provider B and then often stays with provider B (on roaming) too long. Even if I came out of center where my provider A has 4G, phone still uses provider B ... often quite a long time.
I can go to Settings, but it is quite deep and you can't create a shortcut to there. And it also takes quite a long because of the phone checks for all networks in surroundings.
What I want is just a simple jump to my provider A as quick as possible.
Any idea? I saw some apps on Google's Play which refresh network. Maybe this will be a solution.
Probably there is a setting for refreshing somewhere on Android system?

Turn on airplane mode until the data indicator goes away and then turn it back off

Interesting I have the same problem. I always change manually which is very annoying

Thanks.
I'm sure that I have tried this in the beginning. And it didn't work (maybe I change the state too fast and phone didn't disconnect the first network).
I will try this again when the described problem occurs again.

I have tried with airplane mode today (for about 10 seconds), but if reconnect again to roaming provider. After a minutes or two, it automatically reconnects to my main provider.
I didn't look at the phone all the time, because I was driving ... so I will try with this again.

I have tried again (different location and time) and it doesn't work. It simply reconnects to roaming. If I stay there for an hour or more, then it will reconnect to the main provider. Quite annoying.
