[Q] Note on AT&T Data Woes...

[Pscheoverdrive]

Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.

So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...

Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.

So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).


So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?

-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?

-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.

Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.

If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!


Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!

U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.

Reply with your findings.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."

Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

Do all your entries match these? Write down your current ones before changing or take screen shots. You must use the menu key and save changes. Also make sure that is the APN checked after rebooting.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.

To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.

As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.

Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Thanks for the reply, was just wondering where you got a Korean note. hope you can figure it out and good luck.
