Anyone's 3g/4g speeds suffering within the past few days?

Im in Washington D.C.
Rom - Supersonic_1.32.651.6_rooted(stock rooted rom)
Radio - 1.39.00.05.31
Root - Full root with nand unlock (Toast method)
I dont know but Ive had smart phones with sprint since they first had 3g and i was always getting atleast just under a mb down and a few hundred up....
As of yesterday im getting like .3mb down and literally 9kb up....this is after running both extreme labs and speedtest.nets apps from the market.
I have full root(both steps from toast). Ive flashed a few rooms(BB, fresh, etc) but now i am back to the stock rom with root(Supersonic_1.32.651.6_rooted) and i am still getting the same speeds.
PRL updates have been done. I even did a full data restore(##3282#->data*->data restore). Nothing is working
Im pulling the battery for a while to see if that helps.

I was in DC today same phone info as you but with Fresh v.2 Rom
Was getting 2.7 - 4.6Mbps down 1Mbps up

In STL my 4G is around 1.1mb dnld and 3G is around .5mb dnld. Both pretty terrible.

I'm in Kansas City and had been averaging 4mb download and 1mb upload. This was up until 4 days ago and no I'm lucky to hit 1mb download. No clue what is causing it. I've tried everything I can think of.
I'm getting a friends stock Evo to test later this evening.

Im in detroit running
radio - 1.39.00.05.31
Rom - Fresh
Fully rooted (toast method)
Used Speedtest.net app from the market place
1st try
Download .43 mbps
upload .47 mbps
2nd try
download .68mbps
upload .58mbps
Im sick looking at this...

I haven't got passed the 5.08Mbps but I come close often. I am Starbucks at 3.5Mbps with Wifi Tethering

*update*
Used sprint chat first....the god damn guy JACOB A told me that there was an outage in my area
Called tech support and she ran me through all of the remove battery, data restore, prl update crap again. Nothing worked. she said there were NO outtages in my area.
Then she told me that there is no standard speed on 3g. Ive had 3g since they first got it and always got around 800-900 down and 300-500 up(HTC Diamond, 3 BBs, and the moment). now im getting 200 down and 100 up using speedtest.net app, extremelabs test, AND sprint.com/speedtest(didnt know that existed till today).
She pretty much told me i was screwed.

4g connecting then disconnecting

Ok so I found out today that I have 4g in my area n I will turn it on and it will scan for about 30 seconds and then connect real quick then disconnect I can confirm I have 4g in my area as my friends evo connects . I already tried doing whitslacks
Start over method n same thing .

wow so noone has any insight ?

I have the exact same problem.
If I am using the 4G it stays connected, otherwise:
connected to sprint
scanning...
Obtaining IP Address
connected to sprint

More and likely its a weak signal. It was like that for my area but waited couple months later it gave me a stronger signal now. Unless your friend is picking up signal at your house and you are not. Then I have no clue. Update your prl?

i have a wimax tower right across the street (i see it outside my window)
full bars, perfect coverage

I'm having 4g trouble as well. I have full reception and am in a confirmed working 4g location. The phone keeps scanning for 4g but can't find anything.

that's a different problem if you can't connect at all.

I think I am bouncing around to multiple wimax towers.
Any idea how to fix this?

I had the same problem on PRI 1.3x when upgraded to PRI 1.4x the problem was fixed. I made the mistake of upgrading to 1.77 and now my phone connects/reconnects all the time on 4g.

Im located in best coverage area and I cant find a signal. I live in SI NY, 4G just went live the other day. Even though the map says I have signal could the signal not be lit yet? I have a rooted stock rom 2.2 evo, I know someone with an unrooted evo but they dont have 4G by their house yet, I will have them test it as soon as I can.

ok i got in contact with someone with an unrooted evo and they checked a different part of SI which the map says has coverage and he cant get a signal.

Not once (except for ookees) did anybody say if they were rooted or not, what ROM they are using, or any other information except for "I have 4G coverage, I cannot connect". Need more information.
Edit:
Also, the OP has "current phone : samsung vibrant rooted running vibrant 5" in his signature...which is on Tmobile and doesnt have 4G.

Any idea where we can get PRI 1.4x?
This is really frustrating. If I am in other areas, my 4G works fine.
If I keep the link "hot" by constantly using data, it wont drop the 4G connection.
Otherwise-
Connects, works for 30 seconds, disconnects, scans, reconnects with new IP, disconnects, over and over and over.
My wimax radio is NOT broken, 4G does work in most areas, but at home where I get multiple 4G towers surrounding me (downtown) I think it is tower jumping.

anyone? can anyone help with this?

download the WIMAX RSA key checker from the market and see if your RSA keys are missing, if they are i feel bad for you. (I lost mine aswell) Im still dealing with sprint to get my phone either replaced or covered by insurance (which means i have to fully unroot it and claim it as a software issure with an OverTheAir (OTA) update. They usually fall for this and replace it no charge. But if they find out or expect root, they make you pay a 100$ deductible to get a refurbished phone (rooted or not) but there is a slight chance you'll get an Evo 3D in return ^_^ I hear they're not handing out Evo 4Gs anymore

Nexus 4g question? Concerning connectivity

I recently picked up a nexus (Verizon) and love the phone. Have been around android and rooting hacking modding for many years. Of course I immediately unlocked and went straight to jelly bean. The issue I am having is maintaining a good 4g connection. I'm blanketed in it. My Maxx never dropped 4g so I know signal isn't an issue in my area. When it comes in its very strong 20+ mb DL speeds...but it might last anywhere from 2-5 mins. I reinstalled 404 radios. No fix. Wiped and reinstalled my ROM and it did great for an afternoon and then started turding up again.
So now I have wiped again and am trying another ROM out. So far it seems OK but I haven't fully been using 4g as I was off today and home w my WiFi. Tomorrow will be the test.
So, saying it does start dropping out again, is there a pretty solid fix? I have thought about making a full backup on my PC. Then completely wiping and reinstalling the original 401 image and OTA up in hopes of it correcting.
3g never drops data. Only 4g. Seems like there has to be a good fix other than just swap it for a refurb. Any ideas would be appreciated.

Please delete. I verified its my phone.

Update.
It isn't my hardware. It is actually the prl affecting my phone 15145 after switching to share everything plan . Verizon just pushed a different prl and for the last 4 hours I have only had data dump once. Very happy now.

droppping from 3g to 1x

for some reason after i flash a rom i will only get 1x and i have to go back to a stock rom to get 3g back. has anyone else had this problem?

Check your prls and modems
Sent from my SPH-L710 using xda premium

i have updated the prls and i was on the latest modem and it was still doing it. then i tried downgrading to LF9 modem with no change. im on the LG2 build.

Which ROM? On Cm10 early builds I only showed 1x but if doing speed tests and looking at dbm signal output I was still getting 3g speeds.

i first tried it on blazer ROM 1.5 then i seen there was an update so i tried 1.6 but got the same thing

i have also just tried it with Team VeNuM's blue themed rom and i have the same outcome

What kind of real speeds are you getting when you speed test? It's entirely possible that you truly only have 1x speeds in your area. Sprint has "strongly encouraged" Samsung and HTC to always show 3G in areas where there is supposedly 3G. Most custom ROMs have corrected this by showing actual speeds in their ROMs. So it could also be that you truly are only getting 1x and the stock ROM is falsely reporting 3G.

ok well now that im home (i was away on vacation in the Poconos) i ran a speed test and got decent numbers this is the results of 3 tests i ran /ping- 92, 77, 76 /download kB/s- 214.6, 236.8, 152.5 /upload kB/s- 78.3, 77.8, 101.6. so i backed up, flashed Team VeNuM's rom and wiped cache but when the phone booted it showed 3g so maybe b/c i was in PA it might have been saying i was in 3g when i really wasnt proving what you were saying jdogg836. so heres the results of the speed test /ping- 121, 134, 206 /download kB/s- 89.1, 67, 64.4 /upload kB/s- 61.1, 28, 58.6 it's showing much slower speeds but im not sure why

Call sprint...lots of antennas are only around 60-70% right now....got to do with upgrading system from my understanding...also...upgrade your radio to LG8 and see what happens. :fingers-crossed:

but that big of a drop within minutes? yea im on the LF9 modem i downgraded from the LG2. are people having better luck with the LG8 from the LG2?

Check to see if the time you flashed has the 1x/3g mod... stock Roms only ever show 3g even when they are on 1x..
You can also go into the market and download netmonitor which will tell you your true network type.
I'm almost willing to bet that's the problem.
I too live in pa and most northern parts only have 1x service.. just so you know.
Harrisburg/reading/Lebanon is where you start getting 3g.
Edit. Most of what I said was already explained. Didn't see jdoggs post.

Personally I've has this problem since day 1 with this phone. On Airave it seems worse than being connected to towers for me. Sometimes mine goes from 3g to 1x to no data. Turning mobile data off and on usually fixes the issue. I've tried all radios, no difference, LG8 seems to keep connection longer.

If you have the original airave it only has 1x.
The newer version the airvana has 3g coverage..

I've had newer one since the day it came out, no problems with any other phone I've had, just s3. I believe the problem to be the phone, sprint, or my isp.
this message brought to you by my GalaxyS3

I have had modem issues since day one too, I got a new phone because of the poor signal and it's the same.
I tried all the radios this weekend and found no real gains with any. I saw the 1x indicator with the CM10 7/29 build and the AOKP ROM.
Stock based ROM all showed 3G, but it would make sense if they are lying, although I would see 1x in distant lands on my EVO.
I will try the speed test.
It's also worth noting that I have a friend with a stock HTC X one getting about the same signal as me, so it may well be that sprint is messed up here.

I'm not sure at this point, tried everything under the sun, just today I got into the Airvana management page and set it to my router's reserved IP for my Airvana. I think its Sprint also, but you know when I'm right under the Airvana, it seems my s3 keeps solid data connection. This could very well be a weak radio in the S3. All I know is I never had this issue with any previous phones. Maybe 1 day someone will figure this out as Sprint Airave techs are worthless, I feel like I know more than they do!

My problem is even worse since I rooted and flashed AOKP. Hopefully someone can help here. I can make phone calls, it shows 1x, but I don't have a data connection...
Wondering if it is my area. I haven't had issues before. Maybe I should call Sprint to see if they are messing with the towers.
UPDATE: Fixed by flashing stock rom and using the ##72786# in the phone keypad thankfully.

Super slow Wimax Problems in NYC with ICS

Hi guys,
Sorry to be turning to the forums, but I have no where else to turn. I was hoping I could find a solution here from someone (or a group) of you guys that might be having the same problem. I live and work in lower manhattan, and I have the Sprint Epic 4G touch. I upgraded to ICS manually the day the update came out and people gave directions on how to manually update. Ever since I've upgraded, I've had SUPER slow speeds with 4G. 3G works fine, but for some reason, I cannot get download speeds on my E4GT to get above 43 kbps on the speedtest.net app.
And it's not just there, on anything that requires an internet connection, it does NOT get above 43kbps. Typically it's 2-7 kbps. I mean this is abysmal. When I use 3G it's usually pretty decent (expected 3G speeds). I've gone to the sprint store and the techs there keep telling me that they haven't heard anything in regards to this. And when I try to prove it to them, it always shows regular 4G speeds of about 4-8Mbps. But I mean it's obviously going to be fast, I mean they have a tower right there in the store or above it.
Whenever I'm near a Sprint tower, the speeds are fine. But if I'm 2-3 blocks away, speeds go down to 2-7kbps. It's so frustrating.
I've done a PRL update, Profile Update. Samsung software update, and update firmware in the System Updates section in system settings. I've been updating all these settings countless times over the past month, and I'm still getting the same speeds on 4G.
It's so bad, I'm seriously thinking of reverting back to Gingerbread (EL29) just in the hopes that it fixes the problem. I initially had problems with the ICS update (overheating, batter running out in 2-3 hours, apps crashing, things just all messed up), so what I did then was a factory reset from the System Settings section and it fixed 'some' of the problems. Battery life is still awful, but its at least fixed other issues. But the 4G part is still horrible! It's been that way since I upgraded to ICS manually.
I searched the forum and haven't really seen people reporting the same thing. It's sporadic, but I was hoping maybe someone on here would have a solution or an idea of what might be causing the problem.
In case you need to know, I'm currently on
Model Number: SPH-D710
Android Version: 4.0.4 (Stock ICS update OTA except manually updated)
Baseband version: S: D710.10 S.FF18
Kernel version: [email protected] #3
Build number: IMM761I.FF18
Hardware version: D710.10
If anyone out there has a solution, please let me know. Or any advice. I appreciate anything you guys can offer. Please let me know. If you need to know anything else, please let me know... I'll write back quickly. If anyone else is having any of these problems, please let me know too. It would be nice to know that I'm not the only one having these problems.
Thank you so much everyone. Hope your having a great day.

It's possible that your phone doesn't play nice with FF18 modem. Every phone reacts different to different modems, so its possible that EL29 was just the modem for your particular phone. From what I gather you aren't rooted, this however, would be your only way to install a custom modem of your choice.

I have the same issue revert back to gingerbread if you want data speeds back. Ive sone evrything in the book to try to fix this and nothing worked.

No need to be rooted to flash a modem with odin, PM me if you need some info.
You can try flashing different modem versions and find out which one work the best for you

You need to try a new modem. On FC24, I have gotten 12+mbps on 4g at work. I used EL29 for a few days and I couldn't get past 2 mbps in the same spot.

Im also in NY and yesterday i tried a few different modems as well as Calk's ICS and Blue Kuban and i was only getting about 1 kbps down. No matter what modem i tried. I went back to Calk GB 3.0 on FG31 and that gave me the best 4g. Im also a manager at RadioShack and i've notice that the 3g on GS3 is alot slower than the 3g on my e4gt...so maybe it does have something to do with ICS.

Gingerbread good.
Ics no good. Bad. Crappy.

I also work downtown but I am close to the Seaport. I have always had spotty and inconsistent 4G in my office but when I go outside it gets very good. I am running the latest FG20 Boost modem and it was working well (even in my office) up until there was a bad storm a few weeks ago, I think a 4G tower was affected. That day both my 3G and 4G service went down at my desk, 3G came back a little later but 4G has never been the same.
Trying some speed tests at my desk now on 4G and I am only getting up to 1111kbps but it is more around 600. 3G speeds are bad today as well, I usually get between 200 to 300 and only getting like 50 today.
Update: Just updated to the FG31 modem and my 4G speeds are still the same but my 3G speeds got better while sitting at my desk today. There has to be a 4G tower problem around the downtown NYC area because I never had speeds this slow before.
