[Q] Data Speed Issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Every time my phone switches radios (Edge, HSPA+, LTE) my data speed seems to be throattled. I would have to reboot the phone to correct the issue.
So for example, I ran a speed test on LTE the results 20Mbps. Then I switched to HSPA+ then switched back to LTE and ran a speed test. Initially it would connect to 10Mbps immediately afterwards it would slow down to 2 to 3 Mbps. It would stay like this until I reboot the phone. I used Odin to flash back the stock from...still the same issue. Anyone have any ideas what's causing this problem?

Woot! im not the only one
I am on the same rom in Vancouver. The first day it was fine...i get nice consistent speeds but when i run the speed test now, it jumps up fast and then throttles down to 2-3 mbps!!
I remember i cleared cache and ran it again ,seemed to fixed the issue for a day or so and now its back to 2-3 mbps. Upload speeds are usually higher too.
Any ideas?

try different rom and kernel see if that fixes something.

i actually had the same issue with QuikWiz 1.0.3 ...originally thought it was that ROM so decided to flash to TPC and realized the same thing occurs
hmmm
see just now i cleared my cache and dalvik cache respectively...im consistent @ 12 mbps download. Not sure how long this will last

I just started experiencing this in the past two weeks. I used to have to restart my phone to fix it but now I just enable then disable flight mode and I get the usual LTE speeds again. Much faster than reboot. I'm also on Rogers, stock ROM.

I guess its not just me. What about ur HSPA+ and edge speeds rates?
For hspa+ I'm only dl'ing at 2Mbps and for Edge I'm only dl'ing at less then 1Mbps. Even after reboots

ATT's network...

Has anyone had a problem today where your phone just cannot connect to ATT's 3G or HSPA network? For some reason, my phone is getting little-to-no signal, and if I do, it is only on GPRS... I CWM'd to my stable nandroid, but no dice, leading me to think that this problem is with the network.
What's XDA's thought on this? Possible dev issue?

Their network is just pretty terrible right now. However, by summer we'll probably be singing a different tune about ATT's coverage when the iPhone user population will even out a bit. Also, I believe ATT threw down a few billion for network upgrades this year. It seems like they really took that Consumer Reports article to heart, so I actually see good things in the future.

interesting.. i spent a few hours yesterday with my phone going in and out with GPRS and no network connection at all. i've had fairly consistent EDGE ever since. i normally see 5 bars of 3G at my current location (newark, NJ).

No AT&T 3G here...but I use edge network, get mostly 3 to 5 bars mostly indoors or outdoors depending on location. At my work, it's pretty good signal and get around 150-180kbps speed but at home is slower which is around 100-125kbps or slower, probably. I usually use wifi at my home with my own internet.
Out of Davenport, IA and I have great HSDPA signal running Perception 10.1 with the included 2.6.32.9 Firebird Kernel. I have flashed a bunch of DGs ROMs and never had issues with connectivity (voice or data).
I also get that the sim card.has been removed and its pissing me off.... btw, im on phoenix 3.5 with a setiron 1.5.6

Las Vegas + ATT = terrible.
I just went on a 2 say trip there, took me 2 hours to download a 37kb attachment with full bars. I'd get 30 text messages at once an hour late, with full bars.
If I had to work on the strip I'd drop att in a heartbeat... that is totally unfunctional!!

My definition of normal is >3Mbps down, >1.5Mbps up... How is yours so different when you are so near? I get these speeds regardless if I'm on HSUPA or UMTS. I tend to use the latter to save battery.
The more I look, the more I think that ATT just capped my speeds 2 nights ago. This is crap. No modem change, nothing fixes it.

i9020a slow 3g speeds?

I just migrated from theN1 to the NS and my 3g speeds seem slow in speedtest. downloads are around 2000kbps which is usual for the rogers network in my area, but uploads are around 60-80kbps and pin times are almost 200ms. I'm using the Koodo version on the Rogers network.

Updating the baseband to KB3 or KD1 should fix up your upload speed.

Hmm that is strange, I was running cm7.0.2 with KB3 and KD1 and had normal 1.1-1.2mb upload speeds. Over on hofo there was a thread where quite a few folks were complaining about capped upload speeds with the NS, people were focused on the source of the issue being the KB2 radio, but it is seeming more like some sort of network issue in Quebec and Ontario as I have never seen capped upload speeds over multiple android phones here in Vancouver. It may be worth doing a nandroid backup, wipe and CM7 reinstall just for testing purposes though.
Here are a few threads that may be helpful:

I'll put my SIM back in my Nexus One and retest. That should rule out network problems.
This is clearly a local Montreal issue. I'm in Toronto this week and HSUPA is almost 1000kbps.
I am experiencing very slow 3g data speeds with my i9020a (AT&T US). I have never gone above 400kbs down on full bar 3g signal.
What's the deal here? I thought the i9020a was compatible with AT&T bands? 3g lights up, but data is just slow. My baseband after the 2.3.4 update is I9020AUCKD1.
Is there a radio flash I can do to get 3g speeds? If not, this thing is going back to Amazon. It's very annoying.
Just went to an AT&T store and they guy changed some settings on my account (I had a 4g plan with my Atrix). Initially, this resulted in faster speeds, but now they have dropped back down to like 300 kbs down on 3g and 100 up on 3g.
I'm so irritated with this. I'm most likely going to return it and go back to my Atrix. It sucks bigtime as I really like the Nexus S.
Is there anything else I can do to speed this thing up on AT&T? Surely there are others who have the i9020a on ATT in the US?

I too have an i9020a on ATT in the Denver Metro area - I applied the 2.3.4 update and saw abysmal upload and download speeds with the bundled radio. I flashed the KB3 radio and immediately saw improvement - consistant 2.0Meg down and 1.5 Meg up. I then went into the ATT store and switched my plan (was on an iPhone and thus had strange voicemail issues on the NS) and since, my data has been significantly slower (1.0 Meg down and .5 Meg up)...
I'm headed back there tonight to see if there is an issue in my account - otherwise, I'm going to start looking into the build.pref changes that others have referenced in the forums...

EVO SHift 3G Network question

I don't have cable internet where i live due to the fact i travel to and from class way to much to use it. I tethered my phone via wireless or usb to my computer and run off of the 3g network speeds. I currently switch between CM7 and then new EVO Shift 2.3.3 leaked GB Test ROM. I noticed that i have 57% signal according to opensignal and when i download anything or load web pages they are very slow no matter how many bars i have. My download speeds are usually around 20kbps to 55kbps max Is there anything i can do to increase the net speed of my 3G connection? Or is there a app on the market place that i can use to improve or some how boost my 3g network speeds.
I've noticed a little bit slower speeds using the Gingerbread leak but nothing as slow as what you are experiencing. Have you tried the fix from this thread? [FIX] 3G Upload & Download Speeds
Sprints network for Michigan, Ohio and all its surrounding states flat out sucks I get them speeds daily and all Sprint keeps doing is knocking 20 and 50 off my bills, I don't care about money off they either need to fix their network or that roam controlling app is going to get me out of contract etf free I don't care to pay good money for good service but when I pay 160 a month for 2 lines I would expect to be getting the 3G Sprint lies and says I get,

Ah is that what it was. I flashed a new rom the other day with the sense 2.1 and everything was cool except the 3g data speed. It was taking 5-10 minutes to download a 1mb file so I had to restore my other rom lol. My normal 3g data speeds are over 1mbps which is super fast. I couldnt even browse the web with the leaked build, it was ridiculous.

hey
going to try what one do you guys do "1.17.651.1 RUU (Stock):" or 2.72.651.2 RUU: i dont have 4g here
i believe 1.17.651.1 ruu is the stock version that's already on your phone, for people that want to flash back to stock settings if the new radio fails to perform. you should flash to 2.72.651.2 if you want an attempt at an upgrade. personally, it did nothing on my end for the internet, but voice calls did slightly improve. i encountered problems too, where it would hang on the htc splash screen. i don't have an sd card adapter... so i had to put my micro in my old htc hero, run that as a mass storage unit, delete PG06IMG from the computer, boot into bootloader, delete everything, clean cache, davilk (i think that's what it's called), and re-load from nandroid backup. after that i saw 1.08... in about phone, baseband version so i guess i was successful lol. pain in the ass, but will further test it later outside and stuff... once the heat drops down over her in n.y. :]
Besides the fact that my 3G speeds crawl. My 4G is SLOWER on occaison than my 3G. Lol, why is this and how can I fix? It all started when I first flashed cm7

Tmobile data speeds after ROM flashing

Ok, so I've been all thru the RIL thread, the radio thread, and pretty much every other regarding improving the data connection for Tmobile guys like me after flashing a new rom but the information I'm looking for is either too scattered or doesn't exist so here we go...
To all my fellow Tmobile'rs out there, what rom are you currently using, what radio, what RIL, and what are your data speeds averaging?
Currently I'm running:
P3Dneon 2.0
Leedroid Kernel V1.4
base: 10.42.9007.00P_10.11.9007.15M
Ril: HTC-RIL 2.2.0159HMQ
Between 7 speedtests I did yesterday on a server 22 miles away here were my average speeds, all done between 6-11pm yesterday:
down: 2.70mbps
up: .25mbps
ping: 220
Interestingly enough, upon (so I thought) reflashing the HTC-RIL 2.2.0159HMQ today, my first speedtest immediately after yeilded 5.68mbps down/.44 up.
I attempted to repeat to see if it was consistant, but in the six tests I performed afterwards on the same server over the course of an hour I averaged
a measly .72mbps down/.22 up.
Now my phone is setup as well as it can be (wcdma preferred, phone is showing "H" and connected to hsdpa) but the data speeds are still absolutely horrible. Anyone having similiar issues or know any tricks to get the speeds back where they should be...?
Maybe not but 4g is hspa

I think you're right anyway...just sitting here watching my phone statistics now, it seems to be spending a lot of time in UMTS, and alternating to HSDPA every so often...
I am on a stock rom the only thing I have done to the phone is root it... I am on "4g" my avg download is 4478 kbps up is 398 kbps. And that is out of 6 test. The fastest was 5689 and the slowest was 2841.

It seems to me that TMOUS users are getting screwed over with the flashing of the radio or new rom in general...
I went from a 6mbps down, 2mbps up with stock rom only rooted phone, to a 3mbps down 1 mbps up with the revHD and LD. I was on the recommended Radio for revHD and Stock radio with LD.
Running the stock rom with S - off and rooted. I am getting a very strong 7 - 9 MB Down and 3 MB up. Live in a suburb of Boston. These are speeds I'm getting during peak hours. (10 am - 6pm)
I do not want to loose those speeds so I'm waiting for a while to see the speeds others are maintaining after flashing new roms.

On a sidenote, I remember when I first got my vibrant (not 4g) and at times i would average 4-600kbs/sec...I'm not even getting that with my sensation and it sucks.
There's got to be a way to fix this, as I'm attempting to go back to the stock rom now and see if there's a difference...

What Rom/radio/RIL are you using?
Hey guys. I'm using my Sensation 4G in NYC. I'm noticing sporadic changes in speed..drastic changes. At some point the download will be a great 3.5 Mbps, and the next second, it will be 200Kbps. I'm standing in the same spot with the same server, and ping of 200 ms.
I'm running all stock ROM, kernel, and radio. Are we thinking it's hardware right now, or does noone actually?

I'm starting to think it may be...or maybe it's disruption to cellular networks from the freakin solar flares I keep hearing about lol...
I just restored a nandroid of my stock rom and my first test got me 2.04/.21, second 2.94/.53, third shot up to 5.09/1.3, fourth back down to 2.37/.36, fifth 1.2/.66, and the last was pathetic at .57/.08. Starting to think maybe it's network or hardware related...???
I didn't install any radios or Ril's. Only Roms installed. I'm thinking about installing the stock rom back to see if it makes a difference.
Edit: How do I check RIL?

I played around with my stock rom and got over 5mbps a couple of times over the course of half an hour, which is quite a bit more than I did with any other rom. Going back to p3d neon 2.0 now with leedroid 1.4 kernel to see if speeds are any different...
My speeds match what I had stock. They do fluctuate but that's normal and it's the network, not the phone. Currently on InsertCoin Sense Android 2.3.4 with stock radio. I did flash the matching RIL from the thread mentioned. I've done this for every ROM update and speeds have been fine.
The "recommended radios" are probably not good for TMOUS Sensations. Just stay with stock radio and matching RIL unless you have some serious issues. If all else fails, there are some TMOUS based ROMs that shouldn't mess with speeds at all.
Installed the default RIL and have the stock radio. Still 1 mbps. Also I'm running a rom made by a USA user.

Could be the network at the moment. If it's a TMOUS based ROM and you're using stock radio and RIL, there really is nothing else I can think of that can affect data speed. Try doing a speed test on someone else's phone side-by-side with yours (and I really mean like in the same room, speeds can vary widely in different areas). Or do a nandroid backup and revert back to the stock ROM to test the speed. Then you can switch back easily.

Who else has bad 4g speeds?

I live in a good 4g coverage area, and still sometimes I notice it being really slow. I'll run the speedtest app, and I'll get speeds of 1Mbps or slower. When I power cycle the phone, and re-run the test, it jumps to 9Mbps. And turning airplane mode on and off does not have the same affect.
Is this happening to anyone else? I'm also looking to see if this does happen to others, if they are also having SD card issues, to see if maybe there's a connection.

Having the same problem everywhere on all connections. I have had multiple replacements from VZW but no luck. WiFi is even slow at home which is a 20mbps connection. Should have stuck with my rezound.

Well that's not very reassuring...have you tried any different ROMs or radios?
I only get 10-12 tops. I used to get 40 when i had my TBolt but I guess with a lot more people on the network. It would happen

I'm on AOKP JB Unofficial Buld 1. Best I've got is 25 Mbps Down 17 up. Haven't tried on any other kernel or ROM
I, thankfully, knock on wood, haven't experienced any slow 4G speeds. But oddly my signal bars never jump above 2. Even in areas that are fully 4G supported areas. It occurred in New York City as well which was odd as heck. The download speeds though are like that of someone with better signal strength.
For those who wish to know I am using Cyanogen Mod 10.

My last speed test was 39mbit down 6mbit up. This is in Yuba City, State CA.
I'm running CM10, Aug 29 build and KT747 kernel.

My speeds are horrible i downloaded the phone info apk to go back to 3g where it's by far faster. Not sure if it's the phone or the tower being overloaded. Some guys i work with have fast connections where other guys are like me and it crawls, all using different phones. I'm on stock rooted.

Just tested it out again, 17mbit up and 2.87 down...its faster in both up/down than the wifi network i connect to near by.
For those of you having bad 4g speeds, I would suggest trying out different modems. When I was on the release modem, i was getting about 5mb/s, after upgrading to the 'OTA' modem I jumped up to 15mb/s. Not the best speeds, but a definite improvement.
