Mods please sticky this.
There's been several threads with people saying that they are getting intermittent slow or no data connections. Some people suspected throttling.
I did some digging around and found that it is a common issue on all ATT LTE phones. I have read up on various fixes, found one that worked, and will summarize it here.
Create a new APN that is EXACTLY the same as your current one with two exceptions:
1. APN: phone
2. APN type: internet
Save the APN. You should now have 2 APNs. Make sure that the original AT&T PTA APN is the selected one with the green dot.
What we've done here is replace the APN just for internet, and left everything else the same. If you try setting the type of the new APN for everything, it breaks MMS.
There are several dead spots in my town where I get incredibly slow or no data , despite my wife's iPhone working just fine. I made this change and now it works perfectly. Same top speeds for upload and download.
The only thing I cannot test is LTE, since I am not in an LTE area. From what I've read, this is an LTW APN so it should work.
Thanks. Works great and I'm in LTE area.
Very interesting.. thanks for the post.
Just for clarity, we're not to remove "internet" from the original PTA, right?
Edit: Oh, and we can name it whatever we want, I'm assuming? Or does it have to match the original to replace it?

You can't remove the original APN - it's not editable. Leave it as is.
You can name the new APN whatever you want, as long as the APN is called phone.
I am so excited to test this out. I just entered those settings and will report back at the end of the day with my results.
I'm in an LTE area as well and have been experiencing an issue where every time my phone goes to sleep google talk looses connection and I no longer get any push notifications for gmail or my exchange email.

Will see if this helps at all. Suddenly I am having a tong of issues with data on the Note. My skyrocket had no issues in this area. The Note just started experiencing issues yesterday. called att and they reset the data connection on their end and it worked for a few hours.
The oddest part is that the indicator shows I am connected
In an lte area btw.
Oh...another oddity...when calling in to att the guy said his system showed my phone was connected to wifi....my wifi was not even on

Nevermind previous post....
Please note, PTA APN is required if you want to use LTE. Phone APN is for HSPA+. If you are in the area where there is no LTE service, this might be the solution for you as AT&T has a network issue ever since it launched LTE that LTE phones with PTA APN can't get consistent internet access when there is no LTE signal.
So, don't DO this if you are in a LTE area. Or else, you will be forced into HSPA+ network instead of LTE network you paid for.
If you select the phone apn yes....you will be forced into hspa. ..actually in my case it went to no cell connection at all.
There is a theory that simply having it there but not selecting it may help...which doesnt make sense but I am testing it regardless

that's basically what this is - having it there but not selecting it. its almost as if it uses it as a fallback when the PTA apn can't get connected in an hspa area. this would explain why my hspa issue is fixed and others can still connect to lte just fine.
This problem is quite wide spread when Skyrocket was first released. Can't believe AT&T still haven't sort this out.

then you did it wrong. make sure the original PTA apn is the selected one, not the new one. also make sure the new apn type is only internet. I had the same issue when I made those mistakes when I was first testing.
Did this and does not work as people have stated. Doing speed test before adding the apn I would get lte speeds. After adding the phone apn my speed test decreased considerably. This was with att pta selected as well.
ATT has to fix the connectivity issues. For myself, when I do speedtest on lte, it is very sporadic! It times out sometimes while doing speedtest. It's very annoying!

it works for those of us in hspa areas. i guess it isn't going to work for lte areas.
I did the fix and still got 17MBPS on speedtest. I got my mms working btw.
Hrm...i think peopke are doing it wrong. In an lte area, Added it per the directions and the connection issues are slighty better...not completely gone.
No difference in speeds. Lte is the same..hspa+ is the same

Installed the .211 leak last night. I normally keep my phone on 3G to save my battery unless I need 4G.
I just went to change my connection and all I can choose from is Global or CDMA/LTE.
Can you not run CDMA without LTE on the latest leak?

Try setting it manually:
Dial *#*#4636*#*#
Or install phone info app from google play
Go to phone info and in network menu change to cdma only and see if it works.
If not, back to your previous setup. Just make sure you get note of it before playing around.

I tried to set it in the network menu, but my only options are to choose from "Global" or "CDMA/LTE"
It looks like verizon has done away with letting the user choose from 3G or LTE.
I'm pretty upset with that considering my battery won't make it through half a day unless I'm on 3G...
If I dial that number, will that put me on 3G only? I'm on LTE, I just prefer CDMA for battery conservation.

Dial that number then press phone information. Change network type to CDMA PRL. It'll keep it on 3G. If you need 4G, dial the number again and change it back.
Just be careful with what you click
Awesome! To revert back to 4G, I just dial it back?

But Ive found as soon as you reboot the phone 4G returns, using Phone Info app, anyways.
I am also on the .211 version and i am automatically switching between 3G and 4G. Maybe it is related to what region you are in?

Correct. I live in Houston, so I have 4G basically anywhere I go in town.
Got it, misunderstood the question. I have been having problems here GETTING a 4G connection...didn't realize it was someone that only wants it sometimes.

Yikes! I hope that's fixed on the OTA! I'm always in a 4G/LTE area, but run CDMA 99% of the time because LTE will drain my battery in under 6hours. On 3G/CDMA, I can usually get 14-16 hours. Glad I just bought an external 1800mAh battery pack.
I'm using the app called "phone info" that was suggested earlier in this thread.
App works great and let's we switch to cdma only without a hitch, and but lte in enabled when I reboot my phone.
I also hope that this minor issue is corrected in the final product version. My phone will drain in a matter of about two or three hours of LTE the way I use it.
Sent from my DROID RAZR using XDA
to make life even easier, download an app called minimalistic text. Once downloaded use it to create your our 3G/4G widget that once clicked on launches the phone info app, seems to work alright for the time being. but a dedicated 3g/4g switch would be great i dont see how something like this could be overlooked by moto/verizon
Just want to note that I'm having the same issue. I cannot find a way to turn off 4g, I tried dialing the 4636 number and it actually dialed the phone rather than launching the config menu. I'd like to be able to disable 4g at times since I am often in an area without 4g.
So the only way I can figure out how to get verizon 3g is to dial *#*#4636#*#* and switch to EvDo ONLY to get 3g. With that, I cant get text messages even when I have full bars and selected no roaming guards. When I remove the EvDo option, I still get full bars, but drop 3g and CAN get messages. I cant roam 3g and get messages? what should I do?
I know in the past I've used ##PRL# to switch to a Verizon PRL. Is that possible on this phone? I haven't tried yet.

Do that, but just press the menu button, and select radio frequency of 800MHz. That's VZW's band. Don't change the radios, just the band. That'll force you to use Verizon's network. Works for me.

How do you switch the radio frequency? Does this get faster 3g speeds than when I am on Sprint? How can this be reversed to go back on Sprint?

Whats your preferred network type when you do that? Everytime I select 800 mhz, I dont have any bars, its an X.
Do you also force your phone to roam?

I'm having a slight issue with this method. I tried it, and I messed with a few settings. Now, my phone stays roaming. I've tried restarting. I've tried wiping and reflashing MeanBean. I have even flashed CM10.1, but it stays always roaming. Anybody know how to get it back to just using Sprint's network?

I got it fixed. And I didn't think I could update profile or prl when I was rooted. I kept on messing with the settings, and when I saw that Sprint's band was 1900 mhz, I flashed back over to MeanBean to mess with the phone settings since CM10.1 wouldn't let me. After I got back to MeanBean, I kept trying to change it, but it wouldn't take. My phone would keep restarting itself before the full change could work. Finally I got it to work again, after getting it set back to 1900 mhz. I've learned quite a bit about it just messing around. But thank you for the help anyways
Hi everyone, I'm new to AT&T and HTC. I'm confused on how the networks should switch.
The area I'm in doesn't have LTE yet so lets leave this out of this
I'm having a signal issue at work. Where I sit I get 3 sometimes 2 bars (-97 to -101dBM) on the 4G network. But data doesnt work. When I use the browser it say error connecting to network and I when I run speed test it either doesnt find a tower or just sits on ping test.
When I look at mobile network type it keeps flipping between HSDPA and HSPAP. I've never see the phone change to the edge or G network unless my battery is almost dead.
Does this sound right or could I have a messed up radio? It does work great when the signal is in the -70s.
Please help. Wondering if my phone is messed up. It is still stock, locked bootloader, unrooted at the moment.

To turn off LTE, open dialer, type in "*#*#4636#*#*", then click "phone info", you will see "GSM/WCDMA/LTE auto" in the middle of the setting page. Switch to "WCDMA preferred" to use only 3G without LTE. You can also choose "GSM" to use only edge network.
Is there not an App or Widget that can toggle LTE and Edge networks?
First time posting on here so please don't tear me a new ass if I'm doing something wrong lol.
I just got a Galaxy Note I (SGH-I717) on AT&T.
Initially I was having problems with reception and 4G and not getting LTE at all. I finally got LTE working my setting up the PTA APN and by dialing *#2263# and selecting a different preferred band (I chose "LTE ALL" in the LTE sub-menu and saved it). I put the SIM back in, powered the phone back up and LTE was working. However my signal bars haven't gone past one bar while on LTE. I get data, and can even send and receive MMS/SMS, but cannot send/receive calls.
Someone please tell me if I did something wrong or am leaving out any vital info.

Perhaps the radio should be updated. The latest official ATT radio is UCMD3.
Check if you have it under settings/about/phone status/baseband. It works on all builds but is the newest radio which improves signal sometimes.

I'm pretty positive that my APN settings are correct (I'll post them in a minute), I think it is probably the band preference I selected in the *#2263# menu. I do know for a fact that the SGH-I717 runs on the lowest LTE band.

Those appear to be as follows in the link I posted. The only difference i saw was BEARER: LTE (default is unspecified) play with this one.. that was different in the post.
Other then that, I know ATT and Tmobile only use LTE Band 4 in the USA anyways.
So LTE ALL under the service menu wouldnt help. Was your coverage always that bad?
Please someone with ATT help this poor soul out. I'm at wits end. Usually this would be something to bug your service provider about. Myabe they can refresh something on your account, or give you a newer SIM card at your local store.

Yes, unfortunately service has always been this bad. I have called AT&T several times/been to the AT&T store and talked to a representative and they have done the following:
- Checked/rechecked my IMEI number (it always matches)
- Checked and rechecked my SIM number (before AND after I received a new SIM card
- Unregistered/Re-registered my phone with the towers
- Called a tech out to the tower to make sure nothing is going on the them (I know its not, my buddies all have LTE running fine on their devices)
Thank you so much, scariola. You've been a helped all you can.
RESOLVED
I believe I have fixed the problem.
I dialed *#2263# to get to the Band Selection screen. I already had selected "LTE ALL" under the LTE Preference menu. I unselected it, chose Back and then End (both under the softkey menu). I then re-dialed *#2263# to get back into the Band Selection menu except this time I selected "Automatic" and chose End in the softkey menu. Re-inserted SIM, and rebooted.
No I get signal 3-5 bars, 4G and 4G LTE where strong signal is available.
I thought LTE was only data and could not be used for calls.

Right. The data is the 3g/4g connection and the symbol next to the bars is the data speed. The bars is the strength of the gsm/phone signal.
It actually sounds like the OP was involved in a tower maintenance scenario and probably didn't matter what he did.
You can do the same settings changing from the mobile data settings menu.
You can't do the same settings from the mobile data settings menu. There you can only mess with data bands. You can turn LTE off or on on my Canadian ROM but you can't use it as the only band. And I didn't think you could even change this on ATT ROMs/radios at all. I believe he used LTE as the one and only bands for phone and data which caused his issue. I have achieved this same result by messing with those band setting found by *#2263#.
However the ability to send/receive texts but no calls does not make sense. That could have been tower issues since they both use the same phone band.

Er, what?
Is that a JB thing because I know it wasn't present on the ATT ICS ROM. Also where is the LTE setting??
The default is "fastest available". If you choose the high speed setting, it will connect to whatever is best.
I assumed JB stock because the OP said he just got the phone.

It's on the canadian version of JB in the settings/mobile network. Missing from att JB though.
You can however force LTE only through the service menu. Att and tmobile use band 4. Not sure about anyone else.
You must dial *#2263# into dialer and select LTE and choose the band your provider supports. That will force LTE only. Dial the same thing into dialer and select automatic* to go back to jumping through LTE/WCDMA/GSM.
I understand it is on the Canadian version as I am using it. The Canadian version also includes LTE. I know how this all works. I have a Rogers note. But my question was to ranger on where he pulled that screenshot from. I always had an LTE option both on ICS and JB. And it was my understanding that ATT left this feature out on all versions and their modem was locked.

You can't force LTE if its not available. Its best to leave it at auto and let the modem do Its job of connecting to the best signal.

It may have been, but soon after I *thought* I had fixed the problem, the same issue restarted. I believe it was an issue with the phone hardware itself, maybe the antenna. I don't know. I sold the phone and got an S3.
No problems with the S3 :good:
I used to have that problem until i changed the MNC to 260
