[Q] fastest modem for captivate - Captivate Q&A, Help & Troubleshooting

i am using cog 4.1.1 and i am having problems with my data my sisters phone has a strong 3g signal and mu cap is only using egde.
i am new to flashing and all i want to flash a new modem
cog uses Baseband I897UCKB1, Kernel 2.6.32.9
waht is the fastest modem or raido whatever i can flash to using cw
i want to use hsupa or 3g what ever the fastest is battery life is not a problem

I9000 modems have faster data but if not paired with i9000 kernel bluetooth will likely not work correctly

You're looking for modems, and that is ENTIRELY dependent on where you are in the world.
Cog 4.1.1 would be using the official 2.2 ROM as a base, so I'm not sure if these modems would help out... As far as I know KB1 is the only working modem with that version of the ROM (I'm not 100% on this).
I would try http://forum.xda-developers.com/showthread.php?t=835272 for the moment, but like I say I'm unsure how updated that topic would be (the latest few posts will definitely have something about KB1 there)... I'll can go through some quick research for you to make sure, but I'm at work right now so I can't at the moment :/
A quick scan through the latest posts seems to say that JK4 and JPG and KP1 modems seem to work best for some users. (Again, not a 100% sure thing).
Hope this helps at least a teeny bit.

I used secret code in sgs tools and enabled 3g and hsupa and It is working fast now something around 1857kbs down and 367kbs up. At 4 bars

I think the modem I have now is horrible... im running serendipity 6.2 and I can't send a message with 4 bars of 3g. And someone sitting right next to me using an iphone sends a message less than a second... what do you guys think??

Speeds as fast as Wi-Fi ? What kind of internet connection is that ? For me , my internet is 15:1 mbps (download:upload) . The speed on my phone is no where near the speeds on wi-fi .
EDIT: I'm getting 3:1 Mbps on my phone through data . I'm on CM7 , Escapist's Kernel with JL3 CM7 modem .
In order to get the "fastest modem" , you have to test out all the modems given to you for your kernel . Some modems are better in other areas , so you just have to test . For the Captivate kernel , the latest modem (if I'm not correct) is KB1 . Try it out and see if it makes things any better . I liked the i9000 kernel / modem combo better because of HSUPA enabled and the features it gives . I got speeds as high as 4:3 Mbps .

You may have an issue either with the flash or something else is conflicting because I am running the same thing and have zero issues always have a strong signal, actually have a signal in places i didn't when I had the stock software- don't think it is the modem they use jk4 as a default modem most roms use the same
I would suggest you go over to the serendipity Q&A section and post this info. so the developers can help you work out your issues- response is pretty good

If there was a definite answer to which modem was fastest don't you think that it would be the standard for all roms? Just like which rom is the best is highly individual

Better result or bogus on phone

Early today I flash cognition and did something stupid but manage to get every thing going.
I downloaded quadrant benchmarker thingy and the results were way better than the nexus one running latest build. But gps doesnt work. Can these result be bogus or can someelse comfirm it
Here are some attach images
That number might even be a bit low for cog. Should be getting around 1900 if you are using the oc.

You ned an i9000 modem with a i9000 kernel
That's if you use it with Cognition. Perception is an i9000 based ROM and doesn't have the issues. However, both Rogers and AT&T gimp HSUPA. And if BT works, HSUPA doesn't, and vice versa.

If you have battery drain issues, check your network traffic. My Gmail was pinging like crazy even when it was set to update at the longest interval. AOSP email fixed it. Feel free to PM if you need more info.

(Q) I897 Cognition 4.1.1, can I have KB1 modem and voodoo sound control?

Ok. Running stock Cognition 4.1.1. The KB1 modem is da s**t on my particular phone/network. Added 2 bars to reception, dl increased ten percent, gps takes 25 sec or so to lock, but tracking is perfect and accuracy consistent 16 ft (in a thunderstorm!)
Question is what other kernels and/or roms are FULLY compatible with this modem, and specifically are there any compatible kernels that allow the sound control portion of voodoo app to function??
Thanks in advance and especially thnx to ALL the devs for their more than awesome work.

Voodoo sound works on this...
Thanks for pointing me to the right thread. After reading that the kb1 source finally dropped and designgears is hard at work again, maybe I'll wait and see what's up with sound in cog 4.2 when it drops. Anyway, whatever I decide this is just the info I wanted. Thanks again!!!

Continuum v6.1

I was wondering how to enable the 3g on my captivate. Im using Continuum v6.1, when I load my web browser it says 3g then turns off n says H. Is this a normal issue or should I flash back to a different rom. Sorry im fairly new to this and I didn't find anything related to my issue in the search
Sent from my SAMSUNG-SGH-I897 using XDA App
H stands for hspa. It is a faster form of 3g, it is capable of speeds twice as fast as normal 3g.
Oh really? That's great thanks man. Learn something new everyday.

Mobile Data speed on a Galaxy S?

Hello all!
I have a question:
Since purchase of the i9000, no matter what custom rom (Cyanogenmod, Miui, stock gingerbread roms, simplicity, Darky rom, Galnet MIUI, etc...) the mobile internet speed rest slow. WiFi works fine though.
Tested with the Speedtest:
WiFi: average of download is around 200-350 kb/s with a ping of 35-80
Data: average of download is around 25 kb/s with a ping of 350-400
Anyone has this problem too? Or is it related to the phone's hardware?
I flashed multiple modems of the region Europe already, still no changes..
I did a test with a friend. Both at the same place, same provider
Me: Galaxy S I9000
He: HTC Desire
Speedtest result:
Me: 30 kb/s
He: 150 kb/s
so it is not my network, but more my mobile..
Please help me

Are you on 2g or 3g?
Sent from my LG-P350 using XDA premium
Both!
At least on top of the phone I see "E" and "3G"..
Signal strength is good too: around -50 or -60 dbm..
what do you have as download speed?
With E also my connection is slow. Only when it is in H (hdspa) the connection is good and fast. It is the provider of your contract that in your region gives you only a slower connection probably.

KB/s or kbps? IT is a big difference and what rom do u use?

I wrote kbps that is kilobits per second so 239 kbps is equal to 29.8 KBps kilobytes per seconds.

I thought maybe a type fault.
so it is slow too your phone?
*sigh*
Could also be a hardware defect. Have you tried the speed with WLAN?
hardware defect? How can i test this?
How can I do wlan test?
Go to market an download Traffic Monitor. Now you can check the downloadspeed over WLAN. Do it nearby your accesspoint and you can see, if the modem is ok. If the speed is good, it seems to be an software problem.

Wifi is working fine.. so i don't get it..
pfff frustrating galaxy s...
Ok so since you flashed different roms and it didn't work here's what you should do( at least i would do like that) do a "remove the recovery prior to flash" thing and flash your stock rom( from nandroid of any other way) then try to un- root. If all this goes well go to the place where you bought the phone and tell them your problem just skipp the "custom rom modem and root part" and when the dude that'sworking says "it will cost ..." you show him/ her the warranty and smile
Now that was the best scenario.The worst is that you fail to un-root or to remove recovery (or both ) then go take it somewhere for repair and hope that it will ne cheap.Hope this helped and that you get your phone back to normal soon.Good luck!

I manage to get 400kB/s (KiloBYTES as in 1000~kB = 1mB).

Could your APN be messed? Your ROM modem?
