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

Yes it does.
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?

UK T-Mobile users

Is anyone else on the UK T-Mobile network experiencing incredibly slow download speeds lately? For the past week or so my speed has been pathetic at best and just plain not there the rest of the time. I've gone through various speed tests and get varying results but the Speedtest.net app (the Ookla one) is showing consistently that I'm getting around 5KB/s at BEST download with the average being about 2KB/s. Upload speed is poor at about 50KB/s but compared to the download speed it's motoring. I'd be fine even with 50KB/s download but the only way I'll see that is using WiFi.
Before anyone says it might be the time of day, server used, website, phase of the moon etc I was already noticing very slow speeds when pulling down apps and simple Twitter updates. These tests just confirm it to me. I just want to know if anyone else is having similar problems before I complain. If nobody else is having issues I might try reflashing the radio because the ROM used makes no difference and if nobody else has issues it's all I have left to check.

Just tested with the same app from my front room (where my signal is pretty weak) and I got 1901 down and 280 up. Could be congestion on the network in your area, but I wouldn't imagine that would get noticably worse over a few weeks..

Not sure what constitutes good or bad on this page but can you tell me what you have under Settings > About Phone > Status > Signal Strength ?
Right now mine is showing..... -63 dBm 25 asu (fluctuates to -89 dBm and 12 asu)

Right now, -69dBm 22asu to -75dBm 19asu.. So your signal is fluctuating more than mine, your best is slightly stronger than mine but your worst is quite a lot weaker.
A 26dB swing is quite drastic.. Possibly interference from something? Are you sat next to the LHC by any chance?

What area are you in?
Im in kent and havent had any issues or noticed anything.

Only if LHC stands for Large Hairy Cat
I'm in the North East, joners. I don't remember it being this way when I first got the phone six months ago and it didn't feel this slow a week or so ago either. I initially thought it was using a custom ROM or some tweaking I might have done but I've counted that out now. It seems like it's going to be a mix of congestion and... (pun warning!) my electrical personality.

How slow does your 3g get?

This is not necessarily captivate specific, but how slow does your 3g connection get?
In the evening at home I get anywhere from 2500-3500 kbps. During the day at work I am lucky to get more than 100 kbps. Signal strength is good in both situations.
I know it has a lot to do with network congestion, but at what point is it not acceptable? I sometimes even have trouble making a call during the day.
I am in the city of Philadelphia, so it not like I am in the middle of nowhere... might actaully be better there.

[Q] Slow upload speeds

I am a new user of a Samsung Captivate on AT&T, right now I'm not rooted and running the stock software, I generally love the phone, it's much better than my iPhone 3GS and I don't have many issues, except that my upload speed is slow.
I got tired of dropped calls on my iphone and my knowledge of other non-iphone AT&T users seems to indicate that the iphone is the problem with dropped call, the captivate holds on to a call, MUCH better than my old iphone and the download speeds are good, streaming music at High Quality via audiogalaxy is working great.
So I don't think their is anything wrong with my phone.
Testing the phone at work, which is generally has excellent reception for AT&T. I get 1.5 - 2mbps down, which is about what I used to get on my iPhone. But I only get around 150kbps up, my 3GS was even much faster than that in this location usually averaging 250kbps and this phone is supposed an upload speed closer to the iPhone 4 I believe.
Any captivate users on AT&T have a similar issue?

I'm in a terrible reception area at work - would need to test at home...
Currently 128k Down and 256k up

I'm kind of wondering if it's a problem left over from moving my sim from my iphone3GS to the samsung captivate, I had to call to get them to change a data plan and to reset my voicemail to the standard old school voicemail.
I've been using the phone for a week and I've never gone over 250kbps with this phone, but according to the specs I should be getting much better upload speeds.
In central NJ AT&T is actually pretty good and we have consistent 3G coverage, so I it's not like I'm out in the boonies somewhere and that's why my upload is slow.
Guess I should call AT&T.

Your upload speed is normally much lower than your download speed. If you were to do the same test on your broadband at home, you would get maybe if you are lucky 3 mega up for every 30 mega down.
Its how all isps are. The problem is not because of your sim. Also keep in mind that a heavily congested area (new York) will always have bad speeds. The more people with data hogging devices, the slower speeds you will see.
Try doing the bandwidth test again in the middle of.the night or early morning when most people are asleep. You might see some very nice speeds then.

I got my answer
I didn't realize that AT&T disabled HSUPA, I just knew the hardware supported it. and since I'm on the stock firmware that is what is keeping me at 150 - 250kbps.
Thanks for the help guys, it wasn't a big thing like I said but I wanted to know if the problem was my old sim card.

4G Speed again

I have a revo and love it. I do alot of tethering though and hate these crappy 4g speeds. I sat side by side with my friends the other day with their verizon phones. Wired tethering, newsgroup downloading. I maxed out around 14mbps...the samsung charge and the moto bionic both were in the mid 20's. We pulled the same files from the same servers. Then we all did speed tests, manually choosing the same servers and the same results came about. Why does the revo get much slower 4g speeds? Can something like this be resolved with a radio software update? I realize the different phones probably have different lte hardware but this is pissing me off. I may have to jump the revo ship soon cuz i got a 4g phone for 4g speed...not 3g plus a little. I do mucho tethering and pull some pretty big files...that's the main reason for me wanting full 4g. Maybe i'm just a jackass

There was a radio upgrade with the v6 update, but has not been implemented as of yet. I do have the radio.diff file that I can put into a zip that someone can flash and try, but I have not been brave enough and wouldn't ask anyone else to be either lol. I can't lose my radio and wait for a new replacement.

Not sure where you are located (could poss check your profile, lol), but here in Portland Oregon, I get anywhere from 14-20Mbps Down and 6.5-11 Up. This has been true with Stock V4, V6 Upgrade, and Revolt Rom. The only time I got higher was when I USB tethered via the ADB method hack. Then I got around 26Mbps Down and 12Mbps Up. Crazy speeds. I love when I can download a large file at 2MB/sec.
As with comparing to 3G speeds. Lucky if you can get 1.3Mpbs Down and .5Mbps Up. Not sure why you would complain about 14Mbps... But, I am also a speed junky, so if I was in your shoes, might be a little frustrated, but still happy with 14Mbps.
-Cybie

14 ain't bad but i'm spoiled by my 100mbit cable service i guess. It's just that i can't get a consistent speed above 13-14mbps/s. I'd like to try that radio update but i don't have the balls to possibly lose my radio....unless a cwm restore will bring it back. I dunno....it's a pointless gripe i guess.

Highest I have seen was 12mbps. I am constantly at about 7-10. Wish I could see higher. I would be happy with 14.

Hell, I was lucky to get 4mbps down in Denver. I noticed on Friday that speeds are up to ~7.5ish. I'm stoked!
