TERRIBLE internet speeds after flashing Cog 4.1

I've only used:
- Eclair 2.1-update1
- DG's leak of 2.2 Froyo
- DG Cognition 4.1
On my 2.2 leak I'd routinely pull 2.5Mbps-3.5Mbps but since flashing to Cog 4.1 I can barely pull 1Mbps, IF THAT.
I've tried a couple of other 850 modems I found in SGS tools but one made it worse and one was about the same.
What can I do to restore the Internet speeds that I'm used to? This is terrible.
Please help! What modem should I try? I'm in the USA/ATT and have a Cappy 1010
Note: My WiFi speeds are fine. I get 10Mbps+ and I only have a 12Mbps plan so I'm OKAY on WiFi but 3G/H sucksssssss

If you are trying to use one of the i9000 modems (JK3, JK4, JL3, etc), you need to use an i9000 kernel as well.

I've looked at the modem thread but it's hard to make heads or tails.
I know I have to match the modem with the ROM, with Cog being Cappy KB1 based I knew I needed to stick to Captivate only modems.
I'm on UCJJ4 and it still sucks. I just want to be able to pull at least 2Mbps and I'll be happy.

You can give an i9000 kernel/modem a try. You don't have to stay with the captivate stuff.
For what its worth, JK4 gives me decent results in my area. You should just keep trying different modems since location makes a difference.

What modem was the 2.2 Leak based off of?

I also experienced the slow speeds after flashing cognition 4.1. I am now using the latest speedmod kernel and the JK4 modem and I get blazing data speeds. 5mbps down and 2-3mbps up. My gps works pretty damn well too

I'd was using the speedmod kernel and JK4 as well on Cog 3.02. If I stay with Cognition 4.1, I'll definitely be going back to them, becuase this rom LAGS big time, all across the board. And just because that's not annoying enough, the pinch-zoom doesn't work in the blasted browser, either. I've loved the Cognition roms, but I'm seriously disappointed in this one.
Maybe AT&T should hire DG. God knows, he built a hell of lot better Rom from the leaked versions of Froyo than all of AT&T and Samsung's people did with official access, and unfortunately, their bad work shines through in Cognition 4.1.1.

I ended up cracking open the zip file for 4.1.1, replacing the browser.apk file with the one in Cog 3.02 - which is quite a bit smaller, by the way - then re-zipping and flashing it to my phone*. I also went ahead and loaded jk4 and Speedmod's latest. Now pinch-zoom works again, the surfing/etc., speed is much less laggy, I was able to also add the Captivate's stock sounds, and (despite the cussing) a good time was had by all.
The battery life seems remarkably good, too, despite some pretty heavy use. And that's even though I haven't yet had the chance to calibrate it or clear stats and caches. I wonder what it'll be like after a few drain-outs and charge-ups?
Guess I'll keep the rom around for a bit and see.

Difference between EE4 and EP1F?

What are the differences between the EE4 and EP1F updates? I'm mostly asking about the radio, but all others will be read too. Just felt like i should know before i make the decision whether go back to Froyo or stay on the GB leak.
Sent from my Droid Charge running Humble 2.2

I'd also like to know, I love Froyo since it's stable and official and don't play on moving to GB until it's officially rolled out but I'm still quite interested in why everyone is in love with EP1F.

I've honestly not seen a difference flashing the leak to GB. My signal strength has always been -75. Although. There are different gb radios floating around. I still have primary. Never flashed a diff radio.

4G issues in EP1F?
My impression is that the LTE radio in the various gingerbread leak based roms has significant speed issues. I had EP1F installed for a few days and I went back to a Froyo rom because my 4G speeds had dropped to 3G-like.
YMMV, if I am wrong about this I would like to hear about it.
I suspect that if 4G is not available where you are, then EP1F would be worth checking out. Netflix will work, if you care about that...

[MODEM][ODIN] EP3HA Modems

For anyone who wants to flash just the EP3HA Modems only. All radios are independent of rom version.
I take no credit for this as it was simply pulled from the most recent leak. Flash at your own risk! If you need to be explained how to do it you most likely shouldn't!

Just flashed, haven't noticed much of a difference yet but I also don't have 4G in my area.

GPS?
When I flashed *just* the kernel with ep1w rom & modem I lost the ability to get a lock with GPS. even after rebooting a few times.
Have you guys tried the GPS/Google Maps since updating the modem?

Seems to work ok for me. Inside my house and get 20 meters accuracy after about 15 to 30 secs.

Download link seems broken.

Seems like download speeds are faster and link is down

It seems the link here was pulled from a thread I posted on a forum elsewhere - I was doing some file reorganization and in doing so it made the link in the OP no good - my bad.

I've been using this since last night, and honestly this is the best modem I've used. I'm not getting more bars, but it holds on to the actual data signal itself loads better, plus I notice that I'm getting a data connection when I have very little signal. LTE seems to be a bit snappier as well, but maybe thats just a placebo effect.
The biggest difference I've noticed however, is battery life. When using Spotify, browsing the web, and other apps that use data, the battery doesnt drain as fast. I think overall having the data connection enabled doesnt drain as fast as previous modems.
It'd be interesting to know if anyone else has had similar improvements.

With data on: Try loading maps, then press menu, then select sign in. This gave me a pop up and it worked for me. Accurate to <10 meters.

Ok, so I have Humble 4.0 which I believe comes with EP1W modem, which I believe contributes to the buzzing noise during phone calls.
Does this modem flash fix the buzzing problem?

so far so good on this new radio..no call issues yet that I can attribute to the modems

Flashed the modem/radio last night. Didn't really notice a significant improvement over EP1W. I have yet to make any voice calls with it. I'll drive around today and see if it picks up a stronger 4G signal anywhere. I normally have 3 bars of 4G at my house.

Been using the new modems for the last two days and I can honestly say these are the best we've seen so far...consistent 4g, increased data speeds, and as of now no crazy static during calls as we've seen on the other gingerbread builds. I'm loving it!

This version is amazing and super stable. I can't imagine why it hasn't been pushed out officially...

EE4 wasn't a great modem either. Darn VIA radio.
But the GB builds have an issue with noises in phone calls that is still there in EP4P, if VZW is also seeing that in testing that could hold it up. And if they plan an ICS release for the phone Samsung might not try too hard to fix it - they obviously haven't been able to do so yet.

+1 The noise happens to me on any 2.3 rom, hopefully it's one of the issues they're trying to resolve before releasing gingerbread, though I hate to be part if the reason it's being held up

i think that something is wrong with my phone. It does not like any custom roms. It freezes and acts up often. Once i put the stock froyo or gbread it flies and works perfectly fine..... And gbread 2.3.5 and 2.3.6 were solid with no issues so far.

I think its the modem. I had my first static incall today after running the 2.3.6 leak for a week.
Never had that issue on froyo roms.
Sent from my SCH-I510 using XDA App

There are some problems with this build as well. It seems to mostly be with the radio, echoing what people have said here. I've had a couple times where I could no longer send/receive SMS and had to reboot (where it immediately started working again).
There's some other weird things going on with the I/O. I use PowerAmp for music and I'm getting strange skips and pauses that I never had before. Could just be my configuration, but I'm still running pretty lean.
The latest rumor is that the OTA is happening on the 29th. That and $3.49 will get you a McRib.

GB is alright. They need to fix the freeze issue that has been on quite a few GB leaks. It doesn't happen that much on EP4P but it's still there. The modems on EP3 were great in the sense that the signal was SO much better, it obtained/held 4g with such ease. Then I upgraded to the EP4 modems and i lose my 4g signal like i did on EE4 but my 3g is actually usable now. Before the 3g speeds were so TERRIBLY slow i could never dream of browsing the web on it. These speeds are reasonable and i think these modems are the best so far. They need to combine EP3 and EP4 modems to make a solid, stable 4g connection but a very fast 3g connection when it does drop down. Ontop of all that they still need to fix the ****ty voice issue on all GB versions. EE4 was great with this but the GB modems make the voice quality sound like crap.
So, all in all, even though GB is clearly no where near ready to be launched i still just want them to push it anyway because that means GB source code which means CM7 which means CM9(if we get a dev on it)

I feel as the OP feels. As far as a bad radio, I guess I'm just lucky. I haven't had issues with data loss, crackling noise, Bluetooth problems, or anything else. This phone has been darn near perfect since I got it. The only real complaint I have (which really isn't a complaint) is battery consumption. I wish it was a tad better but I manage just fine. Oh, I do wish there was more memory too. I haven't been able to play a couple games because of low memory. Battery and memory are my only real issues at this point. Still, I'm overall very happy with the Charge and would have no problem staying with it if I didn't have an upgrade available.

The modem is better than before. I'm not saying the modem is good or ready yet, but it is working better than any of the last 2 or 3 that I've tried / used.
I sure hope they don't screw up the O/S portion or give up completely because they radio is crap.

Where did you hear that bro?

This release is solid
I was sick of waiting so I flashed this ROM to my phone and I have had the same results as the op. The phone is so responsive and snappy. It is like a new phone. I used to experience numerous data drops before and now, maybe a few in the last ten days. I have not had any of the static/call issues others have had. GPS is still slow to lock. Download GPS fix from the market and run it before you use the GPS...it helps IMO.
My battery life has improved since porting this release. I am a moderate user (phone calls, text, facebook, twitter, occasional GPS) and I get an entire day from my phone (7:00 am - 11:30 pm). I am sure streaming movies and gaming would cut it down significantly but the casual user will notice a big improvement in battery life.
Again, this is just my personal experience.

I agree that the latest version is awesome.
I guess I am really lucky as I have never had the slightest problem with data, phone call quality or anything else. My phone setup the way it is runs faster & smoother than my bosses Bionic.
The ONLY thing I would change if I could would be the poor battery life, but that's a fact of life with these huge screens etc.

No problem with my Modem. Maybe its your Charge? The leak has been solid for me.

Happy with rooted stock Froyo..huh?

Not sure what's happening but I got my replacement Infuse (bad camera on my original Infuse) and have only rooted and frozen a few apps thus far....and it's running unbelievable for the first 24 hours!!
wifi speedtest is very strong and as good as any other rom I've used....battery life is crazy good...and launcher speed (I always use Go Launcher) is fabulous. AND the biggie...the GPS connected within 30 seconds on the first try inside? Huh?
This is NOTHING like my original Infuse.
SO, I need to test a bit more with data speeds...cross my fingers...and maybe I can keep it almost stock Froyo ROM until the final GB comes )).
weird...not what I was expecting, BUT not complaining.
(Firmware 2.2.1, Kermel 2.6.32.9, Baseband I997UCKH1)

I used to own the captivate and would flash all sorts of different crap on it. I got the Infuse when it came out and have been on stock froyo ever since and it's been fine except for the lack of a native SIP stack.
With modems, everyone seems to keep flashing different iterations and keep getting completely different results. I like to think the majority of modem packages are more or less the same and your speed just depends on where you are and how many other people are using the same data band nearby.
GPS itself depends heavily on time servers and not just satellite connections... I find I can always get instant fixes in a particular area if I ping a bunch of different time servers listed at http://support.ntp.org/bin/view/Servers/NTPPoolServers and use fasterfix app to force the phone to always use the fastest/most stable time server instead of being distributed/randomly allocated a server from some national list. Not saying this is definitely the way to go, especially if you travel around a lot. Just sayin' it might work for you.
