Hi,

I did a speedtest using the speedtest.net app, comparing the three modems.
I would like your help in understanding its meanings:

KF1:
Ping - 374msec
Download - 214kB/sec
Upload - 40.1 kB/sec

UCKJ1:
Ping - 371msec
Download - 183.7kB/sec
Upload - 45.3kB/sec

KB3:
Ping - 117msec
Download - 71.5kB/sec
Upload - 88(!) kB/sec

Of course all the tests were conducted on the same server, a server hosted by my cellular provider (Orange).

So why am I asking for you help?
As you can see, in KF1 and UCKJ1 I got somewhat the same results (KF1 I assume is better because of a higher download speed).
In KB3 I got a lower ping and x2 the upload speed. Yet, download speed was horrifying.
So, what is better? KF1 and UCKJ1 (and among them, which one is better?)
Or, should I choose KB3, due to the lower ping and higher upload speed?

Thank you.

I sincerely hope that you are not naive enough to have posted the result of just a single test of each modem

KB3 should have given you highest Download speed. Higher than Average Upload Speed, & lowest ping. (With slight ups & downs sometimes).

Also, it majorly depends upon which modem gives you the lowest value of (dBm) for same type of network.
If all give you best of it, just do three tests for each, take the average, & go for the one that suits you best

Yes, but which value is more important? Ping or download speed (though I'm 99% sure the answer is download speed but I ask just to be sure).
By the way, other people told me KB3 should give me lower download speed, just like I posted, so its strange you tell me otherwise...

Most people would get Higher download speed with KB3, many don't get even the network with it. & many others do, but get lower speed. Its controversial, & relative.

Try taking average of tests.

If you are into streaming, & you watch videos online, or play online games (with/without tether), better PING is more important.
If you just surf & download, go for higher download SPEED.

Thanks for the answers.
For some reason I flashed KB3 again and speeds were amazing (relatively).
The results (Average of four) were about:
Download - 260 kB/sec
Upload - 80kB/sec
Ping - 105msec

Its strange it suddenly turned from a low download speed to a high one, but it seems for now this will be my modem.

As expected.

Glad to hear it helped you

it was ok... didn't notice that much of a difference ... the amount of bars are still the same

I think the best feature of these modems is not speed but call quality. For those carriers that it works on at least...

Unfortunately I rely on 850 band on the Captivate and this doesn't provide that...

Question:

In any ICS rom I install, every modem I install from Samsung (JVT, JVU, JVR) ends up loosing data connection. I mean, the process is:

- boot device, data connection ok
- sometime after, data is disabled (without any user action)
- data doesn't return
- reboot the device
- data connection ok.

With these modems, sometimes data connection disables itself, but returns without me having to do anything.

Do you know why this happens?

P.s. Yes, I've wiped, went back to GB, flashed stock ROMs, etc, etc.

having good performances eith kf1.
