I'm torn on what to do now. Initially I did the Sprint upgrade to the new rom and then flashed DCD 3.0 kitchen. was having lots of stability issues and slow data speeds(half of what I had with 3.27 radio). To isolate the problem I went back to the new stock Sprint rom. More stable now but slow data speeds on average again of half what I had before. Before with 1 bar I got 700k ish down now I get about 350. Anybody been able to solve this? faster gps lock is nice(suspect it's now using cell tower in combination more efficiently since I get even initial lock deep inside buildings) but don't think that will offset slower data speeds. Think it is same PRL too. 60711 I think. thanks for any help on this.

Did you turn on rev A.? I think sprint forgot that one little detail. I know some...myself included...had to do it manually.
how did you do it manually? I have my msl and everything just don't know where that setting is. thx.
I JUST read another thread over at pdaphone home that said on PPCGeeks they recommend that you leave the rev A setting as "Disable"...since its supposed to already be on. People have reported big jumps in speed when it is set to Disable.
To check: ##778# > if you dont have your MSL then just view it > select data parameters...I think.
tried it both enabled and disabled after soft reset. not much difference. still about half of what I used to get. may go back to 2.3.2 and 3.27 radio as I didn't have many problems with that other than slow gps lock. Would be great to have best of both worlds though
The one thing that helped me most was changing my DNS to OpenDNS.
Also; Speedtest sites seem to be TOO FAST for the browser to handle the data, so to do a reliable test try tethering the phone or use wmwifirouter. In my case my phone usually says it's getting around 350, but when I tether it actually turns out to be between 1000 and 1800.
FWIW; I use the dsl reports speed test to check the speed.
You could of course also make yourself a nice 10Mb file and test the speed manually.
Changing the Rev.A setting does NOT make a difference, if anything it makes it slower. Leave it as it is.
I am on Sprint. I am using wmwifirouter v.91 and using speakeasy's speedtest which consistently used to give me 800-2000K(sometimes over 2meg), With new radio struggling to reach 500K. By opendns do you mean 4.2.2.2? haven't tried that. suspect it would make a difference for latency/lookup speed but not so much for data throughput right?
To compare, we should all use the same test and browser. So use PIE for real world results (Opera uses a proxy) and I've found the www.mobilespeedtest.com has a better test than DSLReports.
Anybody have an even better alternative besides tethering?

4.2.2.2 is a Verizon DNS server. OpenDNS is different. See opendns.com

I have to disagree about the accuracy of each site... I have a full T1 at my disposal, and mobilespeedtest.com churned out the following:
Your current bandwidth reading is:
645.00kbps
www.dslreports.com/mspeed, however, returned:
1358 kbit/sec
I would go with dslreports. ymmv

DSL reports only tests 1 file size at a time and the smaller files always fail. We need to find a better option.
Edit: I've got a 6MB connection, DSL reports first said it was 1.9MB but then failed on 3 subsequent tries (too fast).
Mobilespeedtest gave me 277.40kbps first try 749.30kbps second.
So you're right.

I second that.
I tried mobilespeedtest.com yesterday while connected to a 6meg line...speed was rediculously low didnt break 500k. Tried speakeasy.net...I got 5.9 meg.
Just got 225kbps on dslreports 1meg file and 559kbps on mobilespeedtest with 3.35 radio and stock new Sprint rom on sprint network in rev A area 2 bars(not that great of signal but used to get double this speed at same location with 3.27 Radio)

I have LTE turned on in my area and when I use my wireless tether for root users I get awesome speeds between 2-3MBps but after about 150-200MB downloaded those speeds immediately drop off to just 10-20k or so. Now I rarely go over the 5GB soft cap and even when I do it's only by a few hundred MBs. Is there some sort of throttling going on and any way to stop it?
It has been discussed actually (and with that application), but anyways, at least you tried
Assuming your speeds are bad due to one application isnt exactly a very good test (more so since you did not say what version of the application you are running since that could matter). If you want to be certain, try internet connection mode via usb and download a test file from a location around you, such as from one of these data centers http://www.linode.com/speedtest/ and watch the speed. Doing that, you can eliminate plenty of variables, like the wifi connection on either end acting up for whatever reason and the application.
If it stays constant, then it's the app. If it doesn't, well that's not a 100% indication either. LTE is unstable speeds will fluctuate. If you're only testing from one location, that's not a very good conclusion either.
Whenever you have a problem, try to go through the total process of elimination only focusing on one variable at a time and try to keep everything else the same. Most likely it's you or the current setup on your phone or the application, not verizon. How do I know this? Because many have downloaded way more than you have and haven't been throttled (just from people I know locally with an LTE enabled phone).
Exusting all possible outcomes is a much better conclusion than wildly guessing you are being throttled though.
Another way you can test directly on your phone:
1) open up the terminal
2) type the 3 lines below: (downloads a file, gets the time it took and then removes it after)
cd /mnt/sdcard
time wget http://207.192.68.6/100MB-newark.bin
rm 100MB-newark.bin
*if the above doesn't work, then you need busybox, but nearly every rom/kernel has it that's not stock, so you should by default, have it. If not, search in the market for busybox installer. The reason you see an ip there is wget doesnt play well with hostnames on the android due to the way it resolves domains and busybox generally being statically linked. If you want to try another url, you have to get the ip like above (you can do that by pinging the hostname on your phone).
3)Note "real" the time it took in seconds and divide 100 by that to get Megabytes per second (MBps not Mbps) or by 102400 to get Kilobytes per second (I suppose you could get Megabits, but that's a pretty pointless measurement other than making your connection look fast compared to saying bytes, since your files all appear in bytes and browser downloads show in bytes). If you really care about mbps, multiple what you did above already by 8.
4) when it finishes you have an answer totally on your phone alone.

I believe there is a problem with the "Wireless Tether" app. I don't think it plays well with the 4G, this could be a reason for it. Have you tried used the "Mobile Hotspot" app, that comes with the phone? Do you get the same results?
I have also used the stock mobile hotspot app as well as tether via usb and get the same result. For clarification... I am downloading large files (500mb or larger) from a work server so I know that it's a problem on my phone end and not a problem on the server end. I can be on my home computer and download the files and never drop below 5MBps download the whole time... usually never drop below 10MBps to be honest.
Android police says that the way wireless tether works.. there is no way to tell if you're tethering or not without digging deep into packets.. deep enough that it would be invasion of privacy

That's all good and well but there is definitely something going on here. I've run the same test same file all 3 ways once every 4 hours since my first post and at about 150-200mb downloaded my speeds drop to almost non existent and the same goes for files downloaded from Microsoft and Google among others. Downloading the same file from my home internet does not see this slow down at all. I've even tried letting it run for over an hour like that to see if it was something temporary. It seems to stay throttled down till I've let the phone sit for a few hours without using any data then kicks back up to normal speeds until I restart another large download.
Is there any way to do a more controlled experiment to see if I'm crazy, unique or what?

yeah...backup your current rom, flash and restore your phone back to near stock (still rooted) and try without any meddling (custom stuff) http://www.multiupload.com/26WG1UZCXR http://forum.xda-developers.com/showthread.php?t=1009423
you also never mentioned what android version and rom you are currently using. if it's anything other than froyo, that could be your problem since nothing else is anywhere as stable (by stable, i dont mean "oh it works" i mean as in tested throughly and was put out for non testing release).
Though the above suggestions stated above likely are the culprit, and will help you...there is also a chance that you are indeed being throttled occasionally. Infact, I'm sure we all have been. Verizon has several manned data centers throughout the state who monitor all the traffic happening, and can, and will, activately manupulate the speeds, thoroughput, etc depending on how conjestion things are. And yes, they can even pinpoint it on an individual level...though they rarely do that, tending to focus on what's happening on a more macro level.
I actually wasn't even aware of this until recently, but some guy who worked at Verizon who was also in school for that sort of thing let it slip when we started chatting for a second, to which he received a scathing look from the ***** manager, so that ended the conversation.
I was running DasBAMF 1.6.3 and I did return to stock without root this morning to try it out that way as well and I'm still seeing the same results.

Find someone else with a 4g device and have them download next to you at the same time. Only other option I can think of doing.
I'll try that.
Update:
I got with a few friends and tried a few different things. 3 people with Thunderbolts and 2 with Droid Charge. 2 in Seattle and 3 in Spokane. The Thunderbolts rooted and running DasBAMF 1.6.3 and the Charges fully stock. We tried the download using 3 methods for the TBolt's (wireless tether for root, mobile hotspot and USB tether) and the Charges used the mobile hotspot.
We all downloaded the same files. A 512mb video file, 400mb zipped picture file and a 300mb document file.
My Seattle friends who have had the "official" 4G LTE launch had no issues downloading at all... 1 TBolt and 1 Charge. Download went smoothly and never throttled down at all.
All 3 of us here in Spokane saw the same throttling going on. Could this be more an effect of LTE not being "officially" deployed in Spokane yet? It's not supposed to be officially launched till June 19th but we've been able to access it for several weeks now.

I would say that's a possibility. I get around 130 kbit/sec down, and LTE was officially launched here in december but only at our airport. I've been checking for nearly two weeks now and it's stayed the same. the upload is normal, was 3.5mbit/sec today.
This is all good to know. I'll be in Seattle next week for work. Can't wait to have 4G for a week
just got the atrix and when i download stuff over wifi its almost the exact same speed as if it was downloading over the network. i turned data off and only used wifi and still its slow as hell. my incredible doesnt do this so i know its not an issue with my router. could i have gotten a bad phone? ive only seen like 1 thread asking about slow wifi download so maybe i did?

My wifi is fast.
What is your carrier, what firmware are you on, and what have you done to your phone (if anything at all).
Att I just signed up 4 days ago. I'm on stock 83 firmware. I'd did root it just so I could sideload apps
I'm guessing it's should get a replacment. The wifi shouldn't be like this
I would simply unroot it and trade it for a new one if I were in your situation at an ATT store.
Good luck
why dont you do some speed tests with the app to quantify your slow speeds. then compare to speeds from other atrix owners so you can judge based on the numbers.
its def a problem with the phone. my speed test are about 8 mb/s but anything i download from the internet or market its about 250 kb/s. my incredible will download anything on wifi at about 1 mb/s. i even just put greyblur on and changing roms doesn't do anything

4.1.83 and older firmware on teh atrix has a stupid market cap that limits download speed to a few hundred kb/s. the newer gingerbread builds removed this cap. im not sure about the download speed from the internet though, can you watch youtube vids on 720p on your atrix using your wifi without lagging?
yep just loaded up a couple hq videos and they run perfect
OK, I can definitely say I love my thunderbolt, but I hate the battery life. I find myself using 4g lte about 5% of the time I use my phone. It seems to be the major thing always killing my battery. I've tried everything from undervolting to never turning up my screen brightness and still turning off the 4g lte is the best way to go. Which brings me to a thread I stumbled upon in the Eris forums for a 3g uncapper. My curiosity got me wondering, so I asked CondemnedSoul if this would work for the t-bolt so we could get a boost in speed without our 4g lte. Needless to say he made a test to try out on liquid 3.0......and it worked better than I hoped! I went from 400 kbps to1400 kbps on average, with it peaking at 2200 kbps. That's a big jump to say the least. And on other phones it was causing a force close of network settings which didn't happen on my t-bolt, and no issues with 4g or adverse affects on battery life.
So my question to you is would this interest anyone else? I have a test for liquid 3.0 if anyone wants to try it out.
When I lived in OKC, I was able to pull around 2000kbps on 3G on my stock rooted t-bolt, and sometimes about 1500kbps in ATL, so I'm not sure how much help this would be...
needless to say, I'm willing to give it a shot.
I'd be interested in this since my area doesn't have LTE yet so I just turned it off
Wow....I only got maybe up to 600 on a constant before I tried this. I also live in a smaller city. Maybe I'll try it on a different ROM before this becomes a actual mod thread, just to make sure that it did make a difference. But that's why I posted this here first to make sure it was gonna work, and also make sure people were interested before I start making them.
the speeds you're getting with your 'uncapping' trick is about what I used to get here before 4G went live.
oddly though, I found the 3G speeds on my Incredible 2 to go a bit faster then on my Thunderbolt.
After reading your comments regarding the speeds you got, I retested both with and without the mod, and now i'm not getting a difference. Why I was getting so low of speeds when I initially tested this I don't know. It would have been better had I researched the average 3g speed before testing (sorry for the newb mistake). So back to square one, but this should work eventually as it works on a lot of devices. I'm really glad I opened this q and a post first instead of rolling out a mod that didn't work.
Phone - Galaxy s2 i777, about 18 months old, running the factory ICS update
Ok, so I was initially having problems with my phone rapidly losing charge - Shutting down at 70% booting up at 40%, I assumed it was shutting down because it was over heating due to a large amount of power being discharged at once. I lived with that for a while, I assumed a new battery might fix it.
Next, before I got a new battery, my power button stopped working, so the only way I could unlock my screen was to get a message, or plug the phone in.
Now, I've installed ShoStock3 v2.5.1, (started out installing a kernel by Jeboo) then switched to Siyah v7.9
The power button issue came back after a short amount of time with the jeboo kernel, but seems to be fixed with the Siyah kernel (I'm not sure if that is just a timing/coincidence thing or not, but I thought it was worth mentioning)
My real issue now is that I have almost no service, I get anywhere from a "no service available triangle" to a 3G or H+ symbol with no bars shown. Every now and then I get a few bars, receive a few messages, and then the bars go away.
I assumed it was the modem since ShoStock3 says it flashed the modem during the installation dialog, I've tried using:
UCKJ4
UCLE5
UCLK3
and UCPLC5
so far, and nothing has worked. Maybe I'm just a noob and using the wrong modems, maybe it's a hardware issue, no idea.... so please help me out, I've been searching the forums for a couple of days to fix my problems, you guys have been great so far.
Also, I'm from around Baltimore Maryland in the US if that helps narrow down what modem I should be using.

Modem won't affect service. Are you sure you aren't in a dead zone? Also the battery thing is normal for our phone if it reboots
Nope, not in a dead zone. The issue just started recently, before I had plenty of service. WiFi works, but both my cell service and my GPS won't, which I thought indicated modem... any other ideas?

Try going back to stock gb?
Okay, so I'm still on shotock3 with the siyah kernel and the I777UCLE5 modem. I changed my APN settings around to match what I found in this thread:
Http://forum.xda-developers.com/showthread.php?t=2021401
It seems better than it was, but still not working properly. The connection comes and goes, when I get a connection speed test is showing about:
120ms ping
3.8Mbps DL
.4Mbps UL
But most of the time speed test won't even connect to a server.
Anyone have any idea what could be causing my phone to have service sporadically?
Maybe they're doing service in your area or having issues. Also meteorological events like solar flares and things can wreak havoc on service. May not be you.

Is my problem just some ridiculously easy thing that everyone knows so no one wants to help a noob? Or am I just getting bs answers because you don't it? "Modems don't effect signal", "are you in a deadzone?", "solar flares have been known to mess things up"
Can I give more information to help out? I'm not a noob to forums, I'm a noob to this forum, I've searched, I've read stickies, I just can't find a solution (my searching is probably not as fruitful as an experienced user's)
I haven't tried going back to gb yet, but I will tonight after work if you think that could help. I ran ics for months with no problems though, so I don't feel like that caused the problem (granted I'm on jb now, but still).
I know you guys are the ones helping me, so complaining about bs answers isn't all that smart. But answers about solar flares make it harder for other noobs to search for this problem and avoid posting.

Don't come to these forums looking for help. Then blast the people who are giving you sound advice. I have been running the same rom you posted since release. I too flashed UCLE5 because I haven't had as much luck with the standard modem Sho uses, and have great signal since flashing UCLE5. No issues here. Could be any of the number of suggestions mentioned in this thread. I would suggest you take some of the above advice, and maybe thank some of the people who gave it to you rather than being an ingrate. When you flash a modem run it for a day or so and let it settle in as well. Don't just flash it, run a speed test, and then flash another. Sometimes after flashing it seems it takes my radio's a day or so to even out.

The "service in your area" part is EXTREMELY legit; used to happen to me all the time.
Not entirely wise to criticize those trying to help you.
My problem has been going on for 3 days, both at work and at home, roughly 50 miles apart, and no one else around me has been having any problems. Also, no GPS signal... therefore I think I can eliminate both service in the area, and astrological events.
I think step one before anyone goes to the internet to ask for help from strangers, is to find someone close by and say "hey, do you have at&t? Are you having any phone problems?"

I honestly assumed he was just being a smart ass, I know I'm the one asking for help here so I'm not trying to be an ingrate. The service thing is a fairly easy thing to check though, i can't imagine someone wouldn't check that first. The solar flare thing is funny.... but not really helpful...
I didn't realize that I needed to let the modem settle in first... being a noob, I didn't even consider that. it's been about a day, with noticable improvement from when I first flashed it, but still not what I would call functionable.
the only two suggestions on the problem in this thread were trouble with the service in the area, and solar flares, I was only trying to rule those out. The suggestion on a solution, was reinstall gb. I was initially planning on doing that after work today, but now I think I'll wait for the modem to settle in longer.
Any other suggestions on what the problem could be would be helpful. Again, I wasn't trying to be ungrateful, just trying to point out that i didn't think those were legitimate suggestions on my problem. My apologies... I have used xda posts for past problems, and am immensly grateful to have a community like this around. I have been trying to obey the "suggestions for noobs" "search before you post" etc...
Are you under warranty? You may be having a hardware failure since it is affecting your radio signal and gps.

No warranty, the phone is 18 months old, I haven't ruled out hardware failure. That was actually my initial guess, but then a new modem and time seem to help slightly...
I was under the impression that the gps antenna and the cellular antenna (and the speaker) were on the same piece of hardware, and both the GPS and the radio were controlled by the modem. That could be way off though.
Not sure what modem you are useing now, but you did say with ics you were fine and I am pretty sure the UCLE5 modem was the one that came with my 4.0.3 update. It seems to work best for me. If that is the one you are currently running let it settle a bit. I have also seen some people in other phone forums here complaining of throttling of late as well. Just a thought.
Throttling would be slow speeds though right? Not the lack of ability to even send a text.
When I do have service, my DL speeds have been around 4Mbps, which I think is decent.
My problem is more like the signal fading in and out, it almost seems like when I have a good signal then try to use anything that requires data, the signal disappears, would that be throttling?
No.
His issue sounds like a hardware failure. My I777 recently started having the same problem; I tried everything from flashing different modems, returning to GB, even disassembled the phone and swapped the part that controls the signal reception from my wife's to test.. everything I tried was a no go. I eventually figured out after some intense searching that the motherboard was failing, so I decided to just get another phone. Right now my three year old son uses it to play games and stuff. I'm not saying that yours is the exact same issue, but as Red_81 suggested it may be a general hardware failure. What you need to figure out is whether this is exactly so and what is the root cause, then determine if you want to replace the failed part or just get another device. They're pretty cheap on Ebay. Hope some of this helps point you to find a solution.
