AT&T cutting 3G speed by 80%

I live in the Atlanta, Ga. Metro area. I have noticed that my internet speed would start out at normal speed then get very very slow after a few minutes. I tried some speed tests and the First two Test gets 1250 Kbits, then the speed drops to 200 Kbits and stays there as long as I am connected. If I wait a bit and reconnect, I get the same pattern, a fast connection then an 80% drop in speed.
Is anyone else experiancing this problen on AT%T??

I'm in Atlanta too, but I haven't really noticed that discrepancy.

Your title is pretty much nonsense.
Perhaps what you meant to say was "AT&T's network is so overloaded the speed randomy drops 80%".
Howard Forums has a lot in this regard. AT&T is just overloaded. They've made some adjustments, and it's helped. 4-6 weeks ago I couldn't even download a file without it completely stalling most of the time, now it usually finishes, although probably slower.
Supposedly It's a known problem and it's being resolved as soon as they get to it. I assume it means additional upgrades to infrastructure.

NO Nonsense, what I meant to say was "AT&T cutting 3G speed by 80%" and there is nothing random about it. I can consistantly log on at any time and do one or two speed tests at 1200 mbs then the speed drops to 200 Kbs until I log off. Then log on again and get 1200 Kbs and the speed is dropped to 200 Kbs again. They appear to be detecting large blocks of data and cutting your speed down substantually.

I noticed that if you use wap.cingular as your APN, it does seem to be a bit slower. Luckily for me, I have an actual data connect plan and am able to set up my APN as isp.cingular. Maybe its a PLACEBO, but if im not mistaken, the server that ALL of the Iphone data runs through is the wap.cingular, freeing up the other APN for me . Also, change your dns to an opendns server as that may help with some of the initial latencies. I for some reason have NEVER had an issue with the whole proxy setting dilemma ( maybe because of my specific data plan ) but this may also bottleneck your data too
Hope some of this helps

Dude if my 3G dropped to 200 mbits, I'd be a happy camper.

Is it just me or are you confusing your numbers? If that was the case you could download a file at 20 Megabytes per second after TCP overhead initially then it would drop to 2 MB/s. Now I logically think you either added an extra 0 or two or you ment kilobits.

It wont be long before cellular communications reach that speed ( I hope lol )
Also, does anyone else use the isp.cingular APN and notice a diff, or is it just all in my head lol

LOL, you just implement tables in the signature and up the maximum size so I can list all my other devices too, and I'll be almost as happy a camper as having 200mbit 3G

Hopefully by Monday I will order my AT&T Fuze and then join the ranks of the elite
Will see you in the Raphael forum my brother

Speed is a real issue no 3G and it's likely going to get worse when the Bold is released on 11/4. Here's an explanation of the problem: http://tiltmobility.com/2008/09/speculations-and-networks/

you are right, I meant Kbps.

I use the wap.cingular network and have noticed slower speeds, can someone give me the open dns numbers to plug in?

I'm also in metro Atlanta, but I'm not seeing that. However in recent weeks, I have noticed HSDPA coverage has expanded a bit -- I'm getting it in places I never did before.
Also, your speed figures sound about 1000x higher than I've seen; perhaps you mean kilobits/sec?

I would love to have those speeds. Most of the time where I live the edge is faster than 3G.

I would just love to have 3g in general. Edge only. My sling box is sad

Yes, as every one has noticed, I did mean kbits.
Where in the Atlanta area have you noticed HSDPA? I move around Atlanta quite a bit and have never seen the "H" on my phone. I looked all over the AT&T site and did not find a coverage map for HSDA. Have you seen it any where around the Alpharetta/Woodstock area?

Radio Reception

Got mine today, I've noticed the cellular reception seems to be quite poor. I live in a bad signal area anyway but this seems much worse than my Kaiser on T-Mobile. Most of the time it just sits here searching for a network. Has anybody else noticed poor reception.

Mine seems about the same as my Cruise so it's acceptable for me.

What radio version is it as a matter of interest?
I noticed mine is on the tad bit low too - I'm sure the Diamond1 had more bars

Ditto
Existing phone 2 blobs, TD2 struggling.

Generally speaking in poor signal conditions: my D2 has one bar less reception than my old Cruise. So I can confirm this issue. No big deal for me though untill now.

Radio version is 3.43.25.19

mine seems the same as my TD1 - I also live in a poor reception area

Same here. I guess we'll have to wait for a new ROM with a better radio.

Yeah a better radio would be nice. Having said that the GPS reception seems to be excellent compared to my Kaiser, I even get a fix in the house now.

Hello
For cactusbob :
can you said how Many signals your catch with your diamond II in outside ?
8 or 9 or 10 or 11 or 12 satellites.
Because on my old diamond the first version i catch 11 signal when i'm driving (it has 7201a chip) and the new version had 7200a chip.
Thanks for your reply and what your navigation software.
@+++

About 6-7 satellites outside, using iGo 8

I'm disappointed HTC still haven't sorted this out. My Touch Pro went back 'cos the reception was much worse than my Hermes (which I am still using).

Bad reception
I live in Chicago and use AT&T. MY Trinity was alright, but this one just looks for a signal. I have more missed and dropped calls than received.

Well initially I was not 100% sure but I am now... I'm struggling to hit more than 1 bar on H though on G it's full
I know for a fact I have full reception on H around my area - I live in London so you would expect it!
Put the sim on a few phones now and they are higher.
If I revive the HD, I'll test in that but I am sure that will prove the same

It's odd as well I'm in London as well and my reception for H varies between 1 and 2 in my house outside if I take a walk to my local station it goes between 2 bars and full 4 bars, but in central I get the full 4 bars.

[Q]Improving AT&T data speed

Is there anything like this for our captivate?

They seemed interesting and here in dallas im getting anywhere from .10 Mbps to 2.1 Mbps...
anyone might have a better setting for these?

That is just enabling HSUPA, which many ROMs do.
If you want it to work for data and not degrade call quality considerably, you must either be on a I9000 ROM or using CM7/MIUI

Oh... so since im using phoenix rom I shouldnt worry about it? =/
Bummer thought I could get faster speed than 1.5 MBPS in Dallas...
Thank you.

Upon further review... it looks like the OP of that thread got some positive results tweaking those settings in build.prop
However others got mixed results.
I tested it out quickly and got a slight improvement in download speed but slight decrease in upload speed. I will try it again in a different area this evening, though, because I am testing it in a building with a metal roof and spotty coverage...

I've played around with this the last few months. I've had mixed results. Sometimes it seemed like it got me an increase sometimes not so much. I'm in a rural area and as such I have never seen 5Mbps down. I have seen as high as 4.30 Mbps once in a blue moon mostly after midnight. Its certainly a plausible idea but I cannot say with definite certainty that this will give a speed increase.

I tried it out too but it seems like it is depended on the time and traffic of the server...
Ive seen from .5 to 2.9 on my cappy...
edit: any other results or test to see if there might be a better setting?
Also just updated mine to mosaic.

trickery
I tried putting them in my Nostalgia 1.4 build.prop. See if it makes difference.

I'm in frisco and just hit 3 mbs. Get that in both Denton and here. Have seen as much as 4.5 in both.

I'm on the border of Dallas/Richardson and I get terrible speeds on my Cap. At home I get around 200KBPS if I am lucky. On Monday I was in Frisco with a friend who has an HTC Thunderbolt on Verizon, his 3G speeds were 7000KBPS down while his 4G was 1.7MBPS down. In Frisco I did receive 400KBPS down - wonderful right?
I just tested again at work here in Richardson and out of three test I had network failures. The one test that worked was 67kbps down. This is using HSDPA and a signal strength of -75 dBm 19 asu.
I'm using the newest version of Cognition on my phone. Calls have good clarity and when I am using wifi I get 1.5MBPS down. I don't know why my data service is so bad.
Update: So after typing this post and tested again and got 643kbps down 76 up. I haven't moved from my desk.

That's wild. Metropcs speeds is what you got.
Worst area for me is Rockwall. But at&t is kinda non existent out there.

i'm also on andromeda but got same results on other roms as well.

This is my first smartphone on AT&T and because of where I work I was allowed to get a unlimited data package.
I might try another kernel and modem. Its pretty frustrating that my speeds are so slow.

I'm in Fort Worth and I usually average 4mb down 1.2mb up. I'm also running Phoenix Unleashed 8 with JK4

What is your settings at?
if you did the mod.

I am running stock 2.2 and don't use 3g a whole lot (usually attached to Wifi one way or another), but reading this post I figured I would try running a few tests. With 3 bars of signal strength I got a download speed varying between .86 mbps and 2.07 mbps down over six tests. Upload was never much more than about .40 mbps though. At home my Wifi runs around 9 mbps to just over about 17 mbps for download on the Captivate. The is in north GA, not near a major metropolis or anything.

Im curious about rpicaso's setting for this. Im gettin about the same speed as you bytheme.... i want to be faster!!! haha

Wish it worked.

Rockwall has pretty bad 3G coverage. I have better 2G coverage than 3G at home, so I usually stick to 2G+WiFi. 3G seemed to draining my battery.
I usually pickup towers from across the lake in Rowlett.

Maybe they'll build it up when bush gets finished. I don't get how they have no 3g in Rockwall. I'm in Krum (little po dunk town nw of Denton) right now and getting 3 mbs. Rockwall is a good size city with money.

Not so much up in Gainesville, but we get a good 1.5-2 mbps

[Q] Droid 4 GSM/UMTS Signal level?

Hello, has anyone compared signal levels of Droid 4 to 'real GSM/UMTS' phones?
I've been checking the signal level with android software BestPlace, best I've accomplished is -61dBm, and it's often -80 or smth. I've also never achieved the phone to show 5/5 on signal bar, always max 4/5.
With any other phone I can get decent signal everywhere, as the D4 drops out really often on highways and places with worse reception.
Obviously you can't wait this phone to have as good antenna as real GSM phones because there needs to be antenna for really wide range of frequencies.. But still, any way to make it better.. ?
IMO the 3G-GSM handover is really slow and does work like early 3G-phones.. Very slow switching from 3G to GSM and breaking calls during the switch.

I have the same problem, and despite extensive googling have not found a solution yet.
I tried everything I could find and I am now considering a custom rom.
Sadly also the custom roms don't seem to pay much attention to GSM/UMTS reception, but that search was not extensive yet
Netherlands / KPN

Same problem here. I've two droid 4 and both have a much worse signal strengh than cheep gsm phones.
At the moment i'm trying some build.prop tweaks.
Did you already try something (e.g modified radio)?

low dbm compared to Galaxy 5 / LG3

Hey -
I'm having issues with call quality (other side says I'm breaking up, calls dropping, etc.).
When I compare my signal strength, I'm usually 6-10 dbm lower signal strength than my wife's Galaxy S5. I also compared it to my son's G3, and had a similar variation in signal strength.
Do I just have a bad phone, and should I swap it?
I'm worried that if I swap it, I end up with a refurb that has a partially used up battery for my brand new phone.
Thoughts?

first off, they are completely different devices with completely different hardware. so you cant compare the n6 to the ither devices when looking for issues. secondly, the n6 antenna is supposedly a little shorter than samsungs, which could have slightly worse signal reception, if you live in or near the country (as opposed to being in a city).

Just to be clear, when you say "6-10 dbm lower" you actually mean higher? Like your phone is 100 and hers is 90.

Sorry - should have provided more details:
1. It's a Verizon Nexus -not sure what that translates to for a model number.
2. By higher dbm, I mean that if I'm seeing -107 dbm on my phone, my son's LG3 and my wife's GS5 are seeing -96dbm. I guess the point is, both my wife and son can complete a call standing in the same location where I cannot.
Jim

N6 vs Note 4 dbm
This is by no means concrete proof, just showing that the radios in the Nexus 6 are no slouch...

As @simms22 and @gee2012 said, there are several factors involved. I will admit, the Note 4's in-call sound quality is better than the N6's imho but by no means have I ever had problems with calls on it. I will admit, it does seem lower, but I found a thread yesterday that would increase the in-call volume. I applied it but havent actually tested this yet.
Updated: Im also running a 5.1.1 stock based ROM LYZ28E

As Apple once said, "you're holding the phone wrong." Notice the change in dBm while holding the phone normally (with the hand covering the bottom of the phone) and when you hold the phone just by the top edges.

Actually, Steve, I do notice a drop of a few dbm's when I take the bumper case off. But my tests with other phones are with them sitting side by side, not touching. And the dbm measurements are not really the issue. The issue is that calls on my N6 suck, but the LG3 and S5 are great in the same location.

In case you hit this thread with a search engine - here's another thread with people who are experiencing reception issues:

Ok -
Took the phone back to the Verizon store. I set my phone next to the display model - mine showed 1 bar, the display showed full bars.
The tech took my phone and turned off Advanced Calling, and my signal strength matched the display model. I'm going to play with it at home, but it looks like there is an issue with advanced calling and the N6.
