Sorry to here that, however im on stock 2.1 eclair rooted, custom kernal and my 3g is fast and i get faster speed then your earlier att speeds, Even when i have poor 3g service it still blazing fast, right now im using it to wifi tether using mobile ap to stream music on my ipod touch and was downloading 6mb gba roms and got 4 of those downloaded in like 3 min total.

What rom are u running i have no issues with 1x/3g/4g

Man,i had constant 500-700kbps on Tmobile before lame ass sprint rep promised me 4G in one month of my Epic purcHase(October 11,2010),now im stuck with 70-200kbps(about 120kbps most of the time) and now that I bought the phone sprint reps dont know when 4G is coming to Biffalo,NY.My ATT 2G 3 years ago was faster the Sprint's 3G.

It used to take me 20min to download a movie on,tmobile now its like 2-4 hours.Man,i feel like walkin to Sprint and splittin that dude's head open for telling me all this.

Q

Man my hero had a hell of a lot more speed than the epic on 3g. My hero was 1.8mb d/l 1mb u/l

Epic is 150-250kb and 100kb for dl and ul

Not to mention,the ping is horrible. The epics ping is 150-200ms compared to my heros 50ish ping

On 4g the ping is still horible with 150-200ms, but I get 6mb dl and 1mb ul on average, sometimes I get 1MB/s download but the upload seems to be capped at 1mb/s

I think sprint gimped this phones speeds to ensure the evo was good and banwidth free

Well what ive noticed is that AT&T 3g Speeds Crawl Everywhere i go compared to sprint, sprint has always been the most reliable and fastest for me. Ive been on my HTC touch.Touch pro 2 and My latest epic and always been fast data just slow phones. my epic has been blazzing fast on data compared to my friends iphone, my old phones and gross t-mobile :p

I think it is the network. I get lousy 3g speeds in some places and excellent 3g speeds in others.
[Epic 4G Q&A, Help & Troubleshooting] lviv73:
Yeah,Sprint's ping and latency makes 200kbps seem like 50kbps.But still this is 2011 and not 2007,200kbps on 3G is a joke.

Plus I read that when Epic/Evo have their 4G turned on they lag so much that you have to reboot them 3-4 times a day.
[Epic 4G Q&A, Help & Troubleshooting] Unknown Zone:
It is the network, when I am at my GF house I get very poor 3g speed like 200k-maybe 400k every single time I am there no matter day it is. But when I go back to my house on the week/weekends which is about 150 to 200 miles away my 3g speeds are great 700k-1000k. So now I just expect poor 3g speed when I am at my GF house.
[Epic 4G Q&A, Help & Troubleshooting] nikon120:
I'm envious of you "slow" speeds.

Using Speed Test, I'm lucky if I get 50kps regardless of signal. I've been thinking of bringing my phone in to be looked at, because I think that speed is BS for 3G.
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
The problem is not inherent with the Epic. I get 1243kbps down and 514kbps up on mine. My only points of comparison are my Nexus One on T-Mobile (no longer working, number ported to my Epic) which got somewhere around 2500kbps down and 1000kbps up but that's on HSPDA so that's not really a fair comparison. My Verizon Blackberry 9650 gets similar speeds compared to my Epic in speed tests but obviously day to day internet activity is loads faster on the Epic due to the better OS and faster processor.

My first Epic was defective and, among other problems, it did exhibit low speed (in addition to device hangs, a broken accelerometer, etc) so definitely take it in to a Sprint store and ask about getting a replacement.
[Epic 4G Q&A, Help & Troubleshooting] Art2Fly:
So... Is there any solution to this? Seriously, how in the world does someone "video Chat" with the front facing camera over **** speed? Sprint needs to get their stuff together.... I, however, had my wife's hero and i did a speed test and she gets 800kbps down and 500 up.... in the same exact place where i tested my epic, and it even had the same amount of bars... 3

What's the signal strength (in dBm) of both the phones?
[Epic 4G Q&A, Help & Troubleshooting] jesssiii:
NOOB question: what's dBm and is the best number after the minus sign higher or lower? Right now I'm -85, but at times I've been at -105 or -45. Which of these numbers is best?

HTC Incredible Froyo

UnrEVOked Forever S - off

Baseband 2.15.00.11.19
[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
-45 is great. Almost as though you are right under a tower. -105 is right before you might expect your signal to go away to nothing.

FWIW, I think it is the network. I get 100-200kbps in places and upwards of 1200kbps (download) in others.
[Epic 4G Q&A, Help & Troubleshooting] A_Flying_Fox:

Is it true that Epic start lagin when on 4G is turned on?Another question what kinda speed are you gettin on 4G?

Thanx in advance.
[Epic 4G Q&A, Help & Troubleshooting] crabjoe:
The last survey I saw was from 2009 and 3G speeds were best on Verizon, then T-Mobile, next Sprint and last was AT&T.

Personally, I don't see why anyone that pays the $10/mo premium data fee on Sprint should complain about data speeds. You know Sprint says that the extra fee isn't for data speed (4G); they say it's for the features of the Epic and Evo. You know the large screen, super fast 1ghz processors and such... Hehehehe I had to put that in..
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
It was directed at Art2Fly, sorry for the confusion. I asked because he said his Epic and his wife's phone were showing the same number of bars but bars can be misleading because different vendors can "map" them in different ways - thus three bars on two different phones doesn't necessarily mean that both "see" the same amount of signal.

Right now at my desk, I get -76dBm (five bars on my Epic) and Speedtest gave me scores of 1308/504. I'm not doing anything special, I'm running DI18 pretty much stock. I did notice that my phone performed worse under DK28, not sure if that applies to you or not.

I must confess I'm fairly new to Sprint (my 30 day intro period isn't even up yet). Does the Epic 4G provide any visual feedback to indicate whether it's connected to EV-DO vs. 1xRTT? In other words, could it be possible you have a good connection but to a slower network? That could explain lower speeds.
[Epic 4G Q&A, Help & Troubleshooting] A_Flying_Fox:
No it doesn't lag on 4g. Its just low latency. And on 4g I get 500KB-1MB d/l and 1mb U/L

And that's with 1-2 bars lol
[Epic 4G Q&A, Help & Troubleshooting] nikon120:
Just did another Speed Test contacting my local area server and got: 83.7kB/s down, 83.2kB/s up. Mind you I average @ 50kB/s.

I personally do not know of an application to tell which band I'm using at a given moment, sorry. Then again I haven't researched yet.
[Epic 4G Q&A, Help & Troubleshooting] lviv73:
Thanx,now im deffinetly switching from sprint.On tmobile I was getting close to that on hsdpa 3g(500-700kb) six months ago,now its even faster not to mantion hsdpa+.

I have read that Sprint's 4G supposed to be 8-10mb in NJ,NYC but I also read that in NJ and NYC Tmobile's Hsdpa+ is 7-11mb,plus Sprint has terrible ping/latency.To make it short Tmobile's 3G+(or 4G,thats what they market it as now) murders Sprint's 4G in every way.Plus Tmobiles 3G+ network architecture is cheap and easy to upgrade so we should see more speed increase as they upgrade.Thats why they stuck with hdpa+ instead of jumping to 4G architecture.Sprint's and Verizon's 4G wil beat Tmobile in speed in a long run but not for 2-3 years at least.

Who cares if its 4G if 3G+ is faster and better.

Oh and signal strenght doesnt effect speed.
[Epic 4G Q&A, Help & Troubleshooting] 1greek4u:
Refering to the OP, I'm surprised no one mentioned DK28 as the cause. I had slow internet speed regardless of the ROM I was using when I was running DK28. I'm now flying with 2.1...

i have the evo and the epic i was on the same boat as you cause both sux in 3g speeds. first i thought it was the epic but my wife bought the evo and its the same shi***. at my house i get full bars but download its never over 100kbps and upload its always around 700kbps its crazy that my download its so bad.

I'm on a stock but rooted Epic 4G, and I get around 750 down/530 up kbps with 3 to 4 bars out of 6 with 3G at home.

I'm in Southern California Orange County area, and 4G is sporadic here but I've hit almost 9 mbps down and 1.3 mbps up on 4G at the few places where I've received a 4G signal in the OC. Luckily there is a Sprint tower right by my office at work at the edge LA County, and I get regularly 4-7 mbps inside my cubicle with 4G. My experience with 4G is that LA coverage is great but as you start leaving it it starts weakening near the edges of LA.

I usually leave 4G on and I never really get slow downs due to that so I think its something else.

My speeds were consistently slower on DK28, but here is a short summary of speed tests I ran yesterday with DI18. Crappy data speeds are applicable to every kernel and software version I have used...which is why I blame the network.

I live in small texas town hour outside of austin, my speeds rang from 1500 kbps download to 2000 and 450 kbps to 600 kbps upload. I am on stock 2.1 eclair i dont use and data killer(not really sure what that is) but the ping does sem high its about 300 ms. I mainly stay at home in my office connected to my wifi which is connected to my timewarner which on wifi i get extreemly high speeds.

having some experince with the 3g speeds for a while ,its not your phone its the network you have to complain , and the way sprint works is anything under 300 kbps down is when sprint will do something about it. and you have to stay constantly in contact with them about it. if you have to complain everyday or ask for a engineer to come and do a site test.

they will do some tests ask them what the percentage of throughput they see on the tower if they see anythign below 97 percent then they have to flag that tower for someone to look at.

Hope this helps

Thanks for apologizing, OP, but it's unnecessary. On message boards like these, there are many people with many different experiences. Just because I have one doesn't mean it's the end-all, be-all of all things Sprint. Wait until a few more people post before worrying about apologizing.

Just wanted to say that my only point of reference are the multiple times I took my daughter's two Moments and ran speed tests on all three devices (two moments and one Epic) in the exact same place and the Moments consistently get better speeds by at least 250kbps.

With my friend's EVO against my Epic in the exact same locations, again, is at least 250kpbs faster than my Epic.

[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
And of course on message boards like this, we often fail to consider it can be both things...the Epic may get slower 3G speeds on its own AND Sprint's network might suck in places. The best speed I have ever seen on my Epic is 1200kbps. Perhaps if I had an EVO I may have pulled 1500 in that same location.

Likewise, when my Epic is only getting a paltry 160kbps down, maybe an EVO would be "screaming" at 400kbps.
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
Doesn't Sprint also use the 1900Mhz frequency for 3G? Verizon uses this for 3G as well as does T-Mobile for 2-2.5G and voice which means that if the 1900Mhz band in your area is saturated, it may not even be Sprint's fault - you might have a bunch of T-Mobile users gobbling up the spectrum with EDGE traffic.
[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
Verizon is nearly exclusively 800MHz in Phoenix. Especially after completing their purchase of Alltel (which along with VZW was the other 800MHz carrier in PHX). Some of their EVDO is 1900MHz, but not all of it. In areas where VZW was on the 800-band, they used the PCS band to supplement data coverage, not exclusively for data service.

In Phoenix, T-Mobile and AT&T use 1900MHz (along with Sprint). But there shouldn't be any "interference" from the other 1900 carriers. Sprint may not have enough spectrum to support their customers in this market, but that has nothing to do with how many TM or ATT users are out there.
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
Not tried this yet but flashing the modem was a common thing when I had the Nexus One and I do recall newer modems making a big difference on HSPA speeds (my speeds literally doubled from about 1mbps to 2mbps and higher). Since DK28 was a developer release, my guess was that the modem driver wasn't fully optimized which results in suboptimal performance in some situations.

That said, I did try out the latest Quantum Rom and so far, my 3G speeds are still stable - 1300/500 or thereabouts. I have no idea if Quantum Rom contains a newer modem vs. stock DK28 (I did an Odin flash to stock DK28 first, in case that matters) but I also reformatted to EXT4 so it's possible that file system improvements may be contributing to the faster speed (after all, Speedtest has to be writing it's test file to somewhere, right?).
[Epic 4G Q&A, Help & Troubleshooting] BeerChameleon:
Ok this is bs. tmobile should be at the bottom then right above it is at&t then maybe sprint and verizon on top as the fastest, tmobile sucks!!! At&t is getting better but nothing compares to sprint and verizons data..
[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
Uh, a friend of mine in Wisconsin sent me a screenshot of her data speeds on her AT&T Android (SE Xperia?) phone and her download speeds were about 2500kbps with 1300kbps up.

That's about double what I can get under great conditions on Sprint.
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
Radio waves at the same frequency will always cause some amount of interference, that's just the laws of physics. Spread spectrum technologies can mitigate this in some cases but if all three networks are heavily saturated, it won't really help because you're either constraining these users to a smaller spectral band which slows things down or you're overlapping spectral bands which is going to slow things down.
[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
Well of course, but I don't think the interference should be the type that reduces 3G data speeds to near dial-up speeds. If that were the case, I should be dropping phone calls left and right, since Sprint, AT&T, and T-Mobile all use 1900MHz for voice too (although I realize 1X is still used for voice) since if interference were the culprit, it likely would be a problem whether one is using data or voice.
[Epic 4G Q&A, Help & Troubleshooting] h2g2:
Ever used WiFi and had someone in the area turn on an old, poorly-shielded microwave? :) The bandwidth needed for a stable voice connection is well below even the worst data speeds that folks in this thread have been reporting - 9.6kbps at a minimum.

Also, 3G is much more sensitive to lower SNR (which is fundamentally what the problem would be - the Sprint tower and your phone would see all of this other 1900mhz traffic as noise), more so than voice transmissions. Of course, the only way to know for sure is to bust out a spectrum analyzer and I'm not really interested in spending $5000 to prove a theory so it remains just a theory. :)
[Epic 4G Q&A, Help & Troubleshooting] anthromatt:
Not to mention there is the added problem that not all panels on the tower (or perhaps not even all towers?) have EVDO equipment on them.

At my house with my Airave off, I can get a 1X signal for voice or data in the -80dbm range. The best EVDO signal is usually -98 or so and my ec/io is atrocious (both 1X and EVDO).

The server you're testing with Speedtest.net's Android App also has to do with your connection speed. Meaning, your true 4G/3G speeds can be much greater in general, just weak when testing it on that server (try seperate speedtest servers/locations before judging it completely). My 3G in my house is very weak (1-2 bars, usually 70Kbps), but when I'm @ work (2-4 bars), I have a constant 1Mbps download. With 4G, everywhere near me, my peak has been 8Mbps DL and 1MBps UL.

I'm on Mammons EXT4 Bonsai rom, and was trying to do some speed tests (using the app) before and after removing the Sprint cap (in the ##3282# menu). At first I could barely get a decent reading, the server was in my city but it would lag and fluctuate horribly and I was getting 3G readings of .2-.3mbps for download and upload. I went and removed RTSP proxy and port and retried, but it was the same problem. I tried making the HTTPPD proxy and port 0.0.0.0 and 0 too and tried the speed test again.

I got a consistent and extremely smooth 1.32mbps d/l and .5mbps upload (3g with not very good signal) for about 10 tries until the app lost my position and sent me to a server in Kansas.

If you're having problems with 3g, go change over all the proxies and ports to get rid of all the Sprint stuff and see if it helps.

I noticed the overall cell signal to be much more stable after getting rid of all the Sprint proxies.
