I'm having the same issue, by buddy has an evo 4g and we do a speed test next to each other and he gets over 7mb/sec and i'm only getting .7mb sec. I flashed the FI03 modem along with a couple of others and they not seem to make a noticeable difference. Have any of you gotten it to work with CM10 4.1 ?
[Samsung Epic 4G Touch] wesswei:
The FI03 modem alone will not work. The fix is buried within all the modem, kernel, rom, etc. CM will not work (if you have this issue) until the official version of this fix is released with source code. Until then, use the full FI03 stock TW rom that has full 4g, or use another rom that doesn't have the fix (yet).
[Samsung Epic 4G Touch] Mattix724:
Sources for FI27 was just dropped today... technically the source for the fix has been released.
[Samsung Epic 4G Touch] wesswei:
In other words... soon!

I had no 4g for a week and I thought I broke it doing my flash dances. Turns out sprint was working on the towers and no I get 12mb down. I also had sprint reset my account
[Samsung Epic 4G Touch] mikelav456:
By no 4g do you mean slow speeds our no signal at all? what ROM are you on?

[Samsung Epic 4G Touch] shahran:
So is everyone just waiting this out for JB roms, or did you guys settle for ICS for now? I know they had a leak for JB but that doesn't seem like it is going anywhere in terms of providing a kernel that would come out to be flashed with CM10 to fix 4g.

Just flashed PARANOIDANDROID and still stuck on .7

I get .5mbps down and 1.5mbps up on 4g

I get .5mbps down and 1.5mbps up on 4g which is slower than 3g. is only fast on stock i try 2 roms codename jellybean and blu kuban both are slow

Can we use the 10/25 jb from from the s3?
[Samsung Epic 4G Touch] Mattix724:
Modem? No. The S3 has different radios.
[Samsung Epic 4G Touch] mikelav456:
I'm assuming that most of you have gone back to a touchwiz based ROM to get 4g working. Question for those who have: what is the consensus on the best tw ROM? I'm tired of paying for 4g and not getting 4g, so while I love cm, I think I'm going to have to go back to tw for now.

Don't go to FI27. I feel its not stable at all. And my 4g is too slow
[Samsung Epic 4G Touch] mikelav456:
Is there any update on this issue? I'm on the latest cm10 build and hate that I can't access wimax. Driving me nuts.

Anyone know if a dev is working on it?

[Samsung Epic 4G Touch] shahran:
I don't think there is going to be anything new until Samsung releases the kernel for the JB roms... And it doesn't look like anyone is working on anything. Sucks really.
[Samsung Epic 4G Touch] mikelav456:
Didn't we get the ICS kernel and that didn't help. I'm not too hopeful here.

[Samsung Epic 4G Touch] miketucky350:
Ive noticed this. I used to get blazing 4g on el29 but since ICS I haven't been able to stay conneted plus the fastest speed test is. .500k. Maybe its random and my phone went junk. 3g is solid on ICS but signal is up and down. Fi27 is terrible for me where fh13 is perfect 3g wise but no 4g
[Samsung Epic 4G Touch] RayTrue04:
Any ICS build older than FI03 is running the kernel that have the screwy 4g speeds. No good 4g speeds unless you move to either one of the FI builds.
[Samsung Epic 4G Touch] slvrap1:
Tried fh13 through kies when it was first available, 4g was still slow so back to CM. Went to to el29 because it was just getting slower and slower. Kept getting the pop up to update so i figured id give it another try. Update to fh13 then fi27, the speed isnt as high as gingerbread but definately usable
[Samsung Epic 4G Touch] miketucky350:
I remember being on el29 in muncie indiana. Sending screen shots of 10mb down speed tests. It was bad ass. Now im talking stock. Then came ff18. It was ok but 3g always was at 1000 ping time and 400k MAX. most of the time was next to nothing with full bars. O ya and 4g would connect but either , no data or disconnect. Hmmm. Id reboot, update prl/profile then reboot. Same result. Ive had 3 epic touches the same way. Last week on stock fi27 3g was decent. No 4g. I odin flashed fh13modem Updated prl/profile. After reboot. then 3g was brilliant. Fast and instant ping. No 4g. I then flashed stock eg30. Did full wipe and wipe usb storage. So its full stock. Ran ota up to el29. I dont use speed test app btw. I also test setups on real world usage. Well the results were interesting. Instant voice commands. Web browsing fast. ff18 it ran like a dead horse. el29. 3g was consistant 120-200 ping and no less than 1meg down-2.3 WOW. 4g 80-130 ping 3-12 meg down. Im an experienced flasher. I have ran odin with laptop sitting shot gun. Ill never complain about a modem or rom if i havnt ota stock first. I Will

say what setup are you gonna run? El29 modem gives bad ass 3g on 4i27 stock. Ill give 4g results. this week
[Samsung Epic 4G Touch] pijamait:
Just to report my personal experience:

The FI27 OTA solved the 4G slow speed issue (I am in NYC). The problem is that if I use any source built kernel I get the bad 4G speed again (which is to be expected as I believe the source built kernels are based on previous source files).

The interesting thing is that I tried the Agat stock repacked kernels and there are two FI27 revisions:

tFI27_Agats_Recovery-rev1.zip

tFI27_Agats_Recovery-rev2.zip

Well, theRev 1 works well, no slowdown. Rev 2 has the same slowdown problem as previous kernels.

Anyone noticed the same behavior?

I would have posted in the development section but I can not post there yet.

Thank you, just what I noticed. I hope someone will find it useful.
[Samsung Epic 4G Touch] mikelav456:
This is on what ROM?

[Samsung Epic 4G Touch] pijamait:
I tried Blu Kuban and Standard Rooted Stock FI27.

Standart OTA FI27 un-rooted worked very well... very fast speed, download and upload.. Upload with the repack seemed slower.
[Samsung Epic 4G Touch] shahran:
Has anyone tried to use the stock FK09 kernel on CM10 or other JB roms to see if that fixes 4g.

Currently on stock FK09 and 4G speeds are good, however it sometimes times out and will not wake up. FK09 also has other issues but usable.
[Samsung Epic 4G Touch] mikelav456:
I don't think you can just use that kernel on a cm ROM, but I'm no dev. I'd be carful before trying this.

[Samsung Epic 4G Touch] Bane16:
Yeah 4g has never been the same since ics hopefully jelly bean can fix it
[Samsung Epic 4G Touch] celsius0010:
I've been getting the same results as you... I have tried Sleshepic's, Kuban's, and Agat's Source built or custom kernels and the fastest speed I can get is 25% of Agat's stock repack.. I wonder what the issue could be anyone have any ideas?
[Samsung Epic 4G Touch] jeffrey567:
Why isnt this fixed yet
[Samsung Epic 4G Touch] rwilco12:
Good question. Ask Sprint/Samsung. ;)
[Samsung Epic 4G Touch] RayTrue04:
I thought this was fixed on the FI builds? It was for me.. I got 15-16mbps the other day on Jellybean FK09.
[Samsung Epic 4G Touch] tek818:
So now that newer ICS sources have been released, are these WiMax speed issues resolved with CM9 and possibly even CM10?
[Samsung Epic 4G Touch] melheor:
I too am seeing super-slow 4G even on FI27 (Sleshepic's), the image loading in particular seems really bad (Pandora still streams fine, but album previews barely load). The confusing part is that both the rom and the modem are based on FI27 as well, so in theory the issue should be fixed.

At least my 3G is still good (1.8Mbps vs 500Kbps I'm seeing with 4G).

Lol I was referring to the data speeds being the same. I've tried everything from different modems, prl, and even changing wimax settings.

I'm going to check a few other modems tomorrow. I'm on a quest for a fix. My best guess currently is a kernel issue, but judging on others getting decent speeds, I don't think that's it

This has been happening to me since I got this phone regardless of build or modem. Try my earlier suggestion

Turn 4g off, update profile and prl, turn 4g back on. Sometimes reboot

In addition on aokp since I cant update profile I toggle 4g off/on. Next I open browser and google, click on one of those restaurants, coffee, bars links then click update precise location.

These things sound simple but work for me. Here are the speedtest results to prove it. Look at the numbers and the times of the bottom results.
[Samsung Epic 4G Touch] bjonesy77:
I tried this just now with the FF18 modem and with the EL29 with no success. Still getting terrible speeds regardless of modem. I wonder if it has to do with Wimax settings? I'm trying the FE22 modem and also the FD26 modem now....
[Samsung Epic 4G Touch] someguyatx:
bjonesy77 FE22 is working the best for me, I had some signal loss with FF18 and EL29. Never touched wimax settings. After you flash the new modem do a profile and prl update, open browser and click a few links then do speedtest.

So I went back and gave it another go.

I used the stock 4.0.4 as stated above.

Clean wipe of everything.

No frills, no bells and whistles that i may have had on GB.

Turned off 4g, updated PRL and Profile.

Stood outside, practically in the middle of the street, clear view of the sky giving it the best chance possible.

Full bars on 3g AND 4g but to no avail...same slow speeds. opened the browser and it took forever to load even a mobile website (if it loaded at all)

I thank everyone for all their help! I will be going to back to my "sit and wait" state and fool around with some more GB Roms. :/

I'll be checking and updating threads if I find anything that helps me and my boys from Queens. Good luck to you guys.

apparently its been confirmed with sprint that there are connectivity and battery issues. I'm in the same boat though. Great 4g speeds with EL29 but awful speed with FF18. FF18 rom with EL29 modem doesn't even work, so I think its a kernel issue.:confused:

I'm not trying to be an asshole but its true . Oh so now you want to be an immature prick ok. first of all you are not the only one with the speeds I get them too I do not think it is a ROM issue I believe it is a network issue because I get higher speeds on ICS I've than I got on GB and trust me I have consistent 6 bars of signal/coverage.

Also grow up you sound like a 14 year old girl on her period. Lol
[Samsung Epic 4G Touch] cp320703:
this thread belongs in the official ota discussion thread... why not try one of the many great custom roms availible here that DO NOT have this issue, no one here will be pushing a patch OTA to you, so either take it to sprints forum, keep it in the ota thread, or try something different, but please stop cluttering the place up with crap about the OTA... who cares about the OTA
[Samsung Epic 4G Touch] bjonesy77:
Did you read the thread? The problem IS the update. I can tell you this or sure because I can sit here with El29 on my phone, run a speedtest on 4g and get 12+mbpsdown and 2+ up. I flash the OTA ff18 or the rooted sfhub ff18 and receive .5mbps down and 1.5mbps up. There is clearly a problem with the update and/or ICS on Sprint's 4g and may even be localized to some towers. We won't know until Sprint gives a patch.

People who are having the connection problem are having it on EVERY ICS based rom, not just ff18. CM9, AOKP, FF18, ect.....
[Samsung Epic 4G Touch] PattyNYC:
This is not an issue with sprint. I live in Brooklyn and I have very good 4g coverage. Ive tried almost every modem with FF18 and I can't get any better then 500 kbps down. My uploads speeds are consistent on either EL29 of FF18. I have even tried different ICS roms both the official and leaked versions of FF18. I average 8 Mbps down on any EL29 rom.
[Samsung Epic 4G Touch] bjonesy77:
...then what is it a problem with? sounds like a Sprint tower compatibility problem to me. Especially since it seems to work fine for some but not for others.
[Samsung Epic 4G Touch] Khaaaan:
Im not seeing a problem either.
[Samsung Epic 4G Touch] sledgie:
I actually had this problem a long time ago on the leaked FF18 which is why I went back to EL29. people are not understanding its an ICS issue. Perhaps we can be conspiracy theorists and say sprint did this specifically for the NV updates but...its not happening to everyone.

Its not (or shouldn't be) a tower issue unless somewhere in the prl its trying to connect with the furthest tower away, but then most of us wouldn't have 3 bars.

I ran EL29 baseband (modem) this morning with

~8Mbps down and 1.3 up. Slightly higher than average in my area during the day but I'm not complaining.

FF18 spots me at 0.9Mbps and 0.7Mbps. Quite the difference.

I believe it is a combination of kernel and modem. Just not sure what to test. I've moved back to EL29 until solutions are found.

[Samsung Epic 4G Touch] cp320703:
I just reread this whole sad thread and saw 2 people who said they have it across all roms, that hardly constitutes a statistical majority and points towards a tower/sprint/user cause as opposed to a bug in the build itself... furthermore I do not see these issues, other than a very few people having 3g issues on cm9, popping up in dev threads so of you're having this issue perhaps more research on your end is what you need to solve the problem, as opposed to posting, in caps that ics WILL BREAK your 4g and yelling at those who offer help, most of the folks in this thread are going about it all wrong, hence the combative replies... you're asking for help and flaming those who reply for not being able to replicate your very isolated issue. Change your attitude, do your own research and others will be inclined to help you... the guy saying to turn 4g off update profile and prl and turn back on, possibly reboot was more or less ignored despite posting twice and showing speed test results that verified it solved the exact same issue for him.
[Samsung Epic 4G Touch] bjonesy77:
He wasn't ignored. I tried it and was unsuccessful. I'm only flaming the people who say there is no problem. I've gone through every troubleshooting and isolation method I can think of to no avail. I'm not saying it will break your phone, only that it broke mine. My attitude is only sour towards those who refuse to acknowledge the issue only because their phone works.

Aside from that, I just want some ics love with useable dataspeed

Just because only few report a problem doesn't mean there isn't a problem. Could be a combination of the hardware and software maybe. FYI I also have this problem, regardless of my modem on ICS.

This is not a tower incompatibility issue, or an ICS issue. I posted in another thread and earlier in this one describing the same problems that you guys are having. I finally got fed up and took my phone in to sprint and they sent me a refurb. I didn't want to believe that this would resolve my issue, so I didn't swap my service over for a day or two. I finally switched it the other day and installed the same FF18 update that I did on my old phone using the OTA update package from my SD card. I tested 4G and was hitting speeds from 10mb to 13mb down. I swapped back to my old phone, installed CWM and formatted everything (data, emmc, cache, etc). Then installed the stock EK02 and watched it get the EL29 OTA update. I then used the same FF18 OTA update package from SD card as I did before. Tested speeds again and was not able to get over 150kb when standing in the same spot. Swapped back over to the refurb and it was fine again.

I believe it is a hardware incompatibility with ICS...

I just updated profile and prl like someguyatx suggested with 4g off, my next 5 speed tests doubled in speed from 1.5 mb to 3.0 so he may be correct.

I had this issue several months ago with leaked stock ics roms. I actually unrooted my phone and exchanged it on my total protection plan with no problem. I have had no problem with the replacement. At the time it seemed like no one else had the stupid slow speeds I was getting.

I have a feeling there are a few phones out there that aren't going to work. See if you can unroot and return it.
[Samsung Epic 4G Touch] wesswei:
Sad to say, me too!

I have the same issues everyone else seems to have with 4G on the latest ICS update. I was using an older ICS leak, which was working fine. Much to my dismay, after getting the official ROM, my 4G D/L speeds dropped from about 6-10Mbps to 0.5Mbps; U/L speeds seem the same at about 1.2 Mbps. I'm in the NYC area, which was confirmed by a few others on this thread.

I tried the 4G off, update PRL, 4G on/reboot method, but that proved ineffective for my 4g speeds. 3G seems normal, which is about 0.3 Down / 0.1 Up.

As I mentioned, I came from the 4.0.3 leaked ICS ROM, which I think was FD19. After wiping I updated to the latest FF18. I think I'll trying flashing the modem of FD19 to see if that changes anything.

So my 4G speeds went down to .7mbps after putting ICS on the phone. I have tried out several roms and to no avail the download speed is always stuck on .7mbps, but the upload speed is the same as before and is fine. This is really annoying to me and I don't know what to do.

Hopefully someone can bring some light on to this issue. On one of roms I posted in someone else said that they had this problem too and that they got it replaced with their insurance without paying a deductible, but I don't even have insurance; and I don't think we should have to pay anything to get this fixed for us.

So my brother who also has the same phone updated his phone ota this morning to ICS and I tested his phone, he is also getting speeds lower than .8mbps now.

My speeds in the NYC area on the new ICS were perfectly fine up until recently, I believe it was the day that Brooklyn/LI got hit with bad storms. That day both my 3G and 4G could not connect, finally 3G worked but not 4G. The next day or two 4G was back to good signals but ever since then my speeds went from 10-15mbps to an abysmal 300-600kbps. I think they are throttling, they have to be, I am getting consistent speeds they are just slow, once in a while the speed goes up to 1000kbps or a little higher but that is all.

I am having the exact same problem as you, also in NYC. I have tested this in Manhattan, Queens, and Long Island, with same results. Frequently, my 3G is actually faster than 4G, and also, I have been unable to use Pandora over 3G or 4G recently, but works fine over Wifi. I have a feeling these issues may be related. I have tested this on both the stock ROM as well as CM9, did all profile updates, flashed various modems, and no change. I feel that a phone call to Sprint may be in order. I'm not paying an extra $10 a month for service that's slower than 3G.
[Samsung Epic 4G Touch] shahran:
This really seems like a hardware issue now - that some of our phones cannot handle something with ICS. Going to go to the sprint store today and try to swap out my phone because no matter which ICS is on the phone the speed is always stuck below .8mbps - something is just lagging the download speed. I have put on several roms, radios, factory reset, prl update this and that, and nothing has improved it.
