[Q] At&t Unlocked 3G Speeds & Major Indoor Signal Loss - Vibrant Q&A, Help & Troubleshooting

What 3G speeds do you get with your Vibrant running on At&t's network?
I tend to see about 1.0-1.5mbit down and the same speeds up when i have 3-4/5 bars.
Also when you go indoors do you see a dramatic decrease in signal? I sure do and it annoys the heck out of me. But the weird thing is most of the time I still pull in at just under 1.0mbit down and same up.

Signal depends where you are at, In Hawaii I got decent ATT (TMO edge only) most places,
Here in SFO area I get Great connection with ATT indoors or out (I tested to see how it works here)
So, in Hawaii, 1-up 1-down on Att Here in Ca 3up 1.5 down

In Chicago area with strong signal I get up to 5.9 up and 1.3 down.

Hsdpa not working, only getting 3g...also getting hsdpa+ on vibrant...

I apologize for this thread as it might not be in the correct area, but i figured this is the most relevant for this topic...
I have 2 questions so lets start with the first:
1) For some reason I'm not getting HSPDA network working on my phone. the best speed I've posted is about 3.2Mbs, which is not HSPDA speeds, or at least not as fast as it should be. It also says that i'm on 3G as opposed to H...is there a reason for this. Keep in mind I live in LA and they have one of the strongest networks for HSPDA (at least according to the rep I talked to).
2) Is it possible for us to get HSPDA+ speeds with a radio update. I don't know too much about the radio but it would seem to me like that is what it would take to get the HSPDA+ working as I'm assuming that it is the radio that determins your speed and not the hardware...though I could be wrong.
Just a thought, and a response would be awesome.
Thanks in advance guys and gals!
Those are HSPDA speeds. HSPDA+ should net you faster speeds (in theory). My g1 started hitting those speeds around 6 months ago when they started the upgrade over in Irvine (where I work). From what I know the upgrade was software based in areas that were already HSPDA which means they must have recently flipped the switch in your area. I may have benefited by being so close to the goog's Irvine office. I live in south LA county and they haven't rolled out HSPDA+ service there yet. Still slow 1.5Mb's
intersesting, so it is a switch, so therefore on a vibrant getting HSDPA is possible with an updated radio...?

Based on what I've read HSPDA has a theoretical limit of 3.5Mb's whereas HSPDA+ should deliver 7Mb speeds. So yes it's possible to get HSPDA speeds on the vibrant but not because of an updated radio, as the hardware and software supported HSPDA right out of the box. The new G2 is touting so called 4G speeds but it's technically just HSPDA+. Either way you slice it, once their entire network is upgraded most people should be seeing speeds in the high 2, low 3Mb's.
I received consistently 5 MB down, and 500KB up in the southern Akron and North Canton area, which is south of Cleveland, OH with the Vibrant.

[Q] Speeds and signal consistency on AT&T

Anyone here using the DNA on AT&T and care to comment on what kinds of speeds you're seeing in speedtest and how consistent your signal is? I have seen varying reports about the signal switching back and forth between H and 3G constantly and I know it will probably hit the slower AT&T "4G" backbone with a max 14 mbps radio.
I ordered one to use on AT&T and I wanted to get a feel for what I'm in for before it arrives.

HTC ONE on Tmobile data speeds slow ?

I just got a HTC One on T mobile and waiting to port my number from ATT but the data speeds using speedtest are abysmal less than 500kb and sometimes not even connecting at all. I decided to just test the browser to see if real usage makes a difference not just in the speedtest app and same result web pages taking too long to load and sometimes time out because of slow connection.
I'm in Daly City/San Francisco area, before deciding to switch I did my research and Tmobile coverage shows I should be in "excellent" 4g speeds here where I live.
Before I run back to the store and return it and stay with AT&T , is there something I can do to check the correct APN settings or what else can i do ? I'm disappointed so far, I wanted to try T mobile because of their no contract and cheaper plan but at these data speeds it's just not worth it.
Thanks for any advice / help.
Been seeing great speeds here: http://forum.xda-developers.com/showthread.php?t=2247966
But try out a demo phone in the store and test the speed. It might be the phone, or the tower (temporarily) you're connected to. SF is a market with great speed. I've seen speed tests from ppl around. Definitely better the AT&T's HSPA+ speeds.
last night I posted great speeds, today I'm down to 2g although in a different geographical area.
earlier today I lost all data connectivity, it was something wrong with TMO's system. support had to "hook something up" behind the scenes for me to get it back.
---------- Post added at 11:59 AM ---------- Previous post was at 11:36 AM ----------
Update: I noticed that the phone was defaulting to 2g. No matter what, it stayed there.
Using tips from this thread: http://support.t-mobile.com/thread/37862
I went to Settings > Mobile Data > Network Mode and switched it to WCDMA Only.
The data connection re-set and went to 4g.
Repeating the above step, I went back to GSM/WCDMA/LTE Auto, and the phone reset data and got back on 4g.
I think this all had something to do with this morning's outage.
Tmobile tends to have outages sometimes, a few days ago the network in Dallas was down and I was getting horrible speeds. I say that you wait a bit and see if there is any improvement in the next couple of days. Also maybe call in to make sure that your sim is fully activated.
I'll just leave this..

?? What's the purpose of this post and quoting me?
Thinking about making the switch from Sprint (EVO LTE) to T-Mobile and the HTC One. I'm in the Seattle area (Federal Way/Milton) and commute back and forth to downtown Seattle (5th and Pike) every week day. How's the coverage and speed along the I5 corridor? I've looked at the sensorly data and it looks solid, but just really wanting to get a real world feel from a user.
Thanks!

The Puget Sound I-5 corridor has great Tmo coverage and speed. Never have problems streaming music in my car via bluetooth. Plus LTE in and around Seattle should launch in the next couple of months.

I was already getting LTE in the factoria mall area near T-Mobile head quarters. I was getting speeds around 25Mbps down. I think we are close to lte roll out across all Seattle area, I spoke to a T-Mobile rep in Bellevue store and he says it should be sometime in May.

I and my wife recently purchased One's moving from Sprint to T-Mobile. We live in Oakland. Our speeds are similarly slow. Actually, in the week I've had the phone I've rarely had speeds much higher than 400kbs down. Strangely, upload speeds are usually three times faster. This is from inside my apartment where I typically have 2 bars of 4g...three bars every now and then. These speeds are horrible. I called T-Mobile who responded by dispatching an engineer to the tower I use. Within 24 hrs the speeds almost doubled however T-Mobile's feedback was there were no issues. But after a couple of days speeds had declined back to an avg of 350kbs down with upload speeds still 3x download speeds. In my experience, whenever upload speeds are consistently and significantly faster than download speeds and the download speeds are far below what is expected, then either there is a problem with the network or the network is being actively reconfigured.
Assuming I might just be in a "dead" spot due to geography I decided to test speeds in I my neighborhood as I walk my dog. There are no tall buildings or anything I could see to cause much interference. On my street the speed was about the same as inside. About 1/4 mile from my apt the signal was very strong lighting all 5 bars...but speeds only increased slightly. Throughout the area I walked (1/2 circle around my home with radius of 3/4 mile) the signal strength ranged from 2-3 bars fluctuating to 5 solid bars. But there was not much correlation between data download speed and number of bars. In some places 4g speed was as fast as 10Mbs and a bit down the block it could be low as 400Kbs. The speeds were duplicateable...meaning in front of one house speed might be 5Mbs and a speeds in front of a house say 6 houses down the block speed may be 1Mbs. Those speeds would be pretty much the same when I returned later on another walk.
The most surprising discovery is there is a narrow area about 5 houses wide that had LTE. In that small area the speeds were slightly greater than 20Mbs down and 10Mbs up.
The results lead me to believe T-Mobile is actively fumbling with their towers to get LTE quickly, yet attempting to do so as quietly as possible. Due to my disappointment at the painfully slow data speeds I would consider returning the One's firing T-Mobile and moving on. However, the discovery of LTE 1 1/2 blocks from my home AND MAYBE EVEN MORE IMPORTANTLY no real alternative for an "unlimited" data plan that makes financial sense to me (Sprint is nolonger an option since their network is almost unusable)...has me pretty excited as to what my T-Moble experience will be. I hope they aim that LTE antenna in my direction.
@chakathebird:
Wow, I'm in Hayward which is not too far from Oakland and I also switched from Sprint (which is just awful in the Bay Area these days). On Sprint I was lucky to get over 400kbps on 3G and I couldn't even get 4G LTE. (Although 4G WiMax on my old GS2 was fantastic for me). On T-Mobile 4G HSPA I get 8Mbps down / 3 Mbps up on my HTC One and similar speeds on my Nexus 4. With those great speeds I normally just leave LTE turned off on the One, but I did do a speed test with LTE turned on and got 11Mbps down / 6Mbps up.
I work in the South Bay, but sometimes head over the bridge to San Francisco and travel throughout the Bay Area. Everywhere I go I get similarly fantastic speeds on T-Mobile. So if you are getting such slow speeds there is definitely something wrong with either your phone or the tower in your neighborhood. I'd take the phone to other nearby towns and see if you're getting similar bad speeds. If so, I'd have T-Mobile exchange the phone as it may be defective.
I'm in the Northern VA area and there is some LTE. If I'm not driving around and sitting in one place, I can stay on LTE, but driving around, it's bouncing in and out of LTE which just shuts off data all together. So i turned off LTE till they get more towers updated.
On a side note, the radio in the HTC one seems really nice. At my house I can get 13Mb/s down on the HTC but I can only get 6Mb/s down on my data stick sitting beside me. Both connected at HSPA+.
I am not even running on LTE here in NJ and I am still impressed with the speed. It actually comes pretty close to my friend's GS3 on Verizon with LTE.

That being said...I still can't wait to have LTE here in the NYC area. If HSPA+ is this good then LTE should be ridiculous.

[Q] Data connections being weird

First of all, I live in a suburb of Dallas which is completely covered in LTE according to Sprint's coverage map and I can affirm this by Sensorly and my own personal usage of my phone when I see 4G LTE in many places. However, lately I have noticed on the bottom floor of my house I usually get 1X or 3G, whereas upstairs I get 4G quite nicely. In other houses nearby (less than 1 mile), my phone doesn't even get data many times (and if it does, it is 1X) whereas other Sprint iPhone 5's are enjoying LTE in the same location.
Now I know our phone's have connection issues, but why am I not even getting 3G? Is there anyway to help force my phone to try and get more 4G signal because I know for a fact Dallas has pretty decent 4G coverage? When my phone goes into 1X it also seems to be sucking up quite a bit of battery. Any help is appreciated!
I am running MeanBean 3.09, S-ON, with the newest Bulletproof Kernel.

MeanBean has the Roam only option baked in, just go to settings - mobile network and set it up... The battery drain is "normal" when the phone doesn't have a good signal... Roam or use wifi... I know it doesn't make sense but that's the now network...

Terrible data strength: All locations, inside & outside

Little over 2 weeks with the G3 and I love the device with zero issues besides the very poor data signal strength. dBM rarely breaks into the 90's.
I pretty much get a poor signal all across Kansas City. Work, home and travel between 6 cities to and from signal strength is the same. I always have a working connection but the strength is just not there. My bars always show zero or the itty bitty one bar......but everything works, decently fast and operating.
My old S3 on Carbon and my wifes stock S3 always showed good strength, showed 10dBM less than my G3. Is this just how the G3's radio is setup? On PRL 51102, I may try changing the PRL to see if it helps.

Something should be wrong with your phone. Go back to Lg and replace it. Cause, this phone is best by far i have ever used. I have used samsung Note 2 , 3 S4, s5, G2, G1,S2,S3. And this phone easily is on top for data
Given that you're in Sprint's backyard, I would think the signal strength, both 3G and LTE, would be quite strong across the KCMO region.
Out of curiosity.. Under Settings -> Wireless Networks (More) -> Network (Mobile Networks) -- What is Network Mode set to? Global? LTE/CDMA? If Global, change to LTE/CDMA and see if you see an improvement.
Also, for point of reference, my indoor signal strength at work shows -94 dBm on eHRPD (3G) connection. Fluctuates between 3 and 4 bars. Not sure how that dBm measurement would translate to LTE frequency bands, but I would think it should be similar.
Have you done a speed test to get an idea what kind of bandwidth your device is capable of even with what's perceived to be a weak signal?

One would think yes, being a KC resident home of Sprint I would get great service. In most cases I do.
It's been on LTE/CDMA and global. I haven't noticed if one is better than the other. Maybe a better handoff between 3G and Spark on Global. Update: Just got back from a local Sprint store and talked to a very knowledgeable Technician who has has first hand experience on all LG devices that their signal is like this across the board. Lower signal and dBM compared to HTC, Samsung or Motorola but still get great speeds.
I've done speed tests at the same time I noticed poor strength and actually surprised that despite the signal I get the same speeds as if I had better signal (lower dBM)

I noticed low signal strength on the LTE frequency(the one showing in signal bars by default) from the beginning but it doesn't affect my speeds so I'm not complaining.
Does band 41 show a different logo for spark? I have never had spark, but s3 didn't have have tri-band, so it's possible you are on b41, and it has decent enough strength, so it just stays with b41. I Can keep b25 LTE down to around -117 db. You can check which band you are on with ##3282# and click lte, then view.
