The stock 2.1 captivate firmware has a bug where under certain circumstances, the phone will crash and restart itself. I believe that this is related to having two WPA enterprise (802.1x) networks in proximity to eachother with the same ESSID. I flashed the Cognition 3.02 ROM (which has the JPA version wifi firmware) and the problem still existed. I then flash the JPY version of the wifi firmware and the problem seems to have gone away.

(For me) JPY seems to fix a very annoying bug on my phone, so I'd suggest that it should be preferred.

I tested both versions, and I couldn't see a noticeable difference in drain; they are about the same. Tested for 2 days each, when idle or surfing, and the drain is very comparable.. 1% difference either way in 24 hours is not worth the trouble, imho...

Do you have wifi sleep policy to turn wifi off while screen is off? The main purpose of this driver is to give your phone that capability, to switch from wifi to mobile data while screen is off. Jpy drivers simply don't do it. No 2.2.1 driver does it. At least in my tests.

but thats only a problem when u have a buggy wifi accesspoint, which as no proper implementation of sleeping states. it prevents the wifi of the phone to get into powersaving but stay connected. google it and u will find lists of falty firmwares and accesspoints.

After updating to JS3 I noticed that Running time/awake time has gone from like 20% to 40-50-60% .. Under Partial awake time, I only find Android, with like not much.. like max 1 hour, and that's after a day.. So from JP6 I've gone from 48 hours standby to about 24 hours.. So something's up with the rom.

I'll try turning off wifi now for a couple of hours and see how it goes. I want my phone to sleep, but I like to have wifi always on.

You need to download the Android SDK:

http://developer.android.com/sdk/

Then go to the folder where it's installed and just do that command:

adb shell "dmesg | grep Firmware"

ADB is an interface to control your Android from the computer, like a Terminal with some more things.

I try to see my version but I get this:


# dmesg | grep Firmware
dmesg | grep Firmware
<4>[ 2053.433797] Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214
.3
<4>[ 2787.680723] Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214
.3

Hello hardcore!

I've been having a quite high wifi battery usage so I decided to try out DXJPA in order to get an improvement.

The thing is, after flashing it through CWM with your attached zip, whenever I check my firmware it still says XXJPY is my Phone firmware. Is this intended or DXJPA ain't getting flashed properly? If so, any possible fix?

Thank you for your time and hard work!

    UPDATE:

    I've put up a post with update.zip can that change your wifi firmware version. DXJPA's wifi firmware seems to use less power than XXJPY's.

    ----------

    Hi guys,

    I'd like your help to find out which Wifi firmware versions are included with which PDA firmware package.

    This is what you can do to help:

    1. Find out your Wifi firmware. Turn on your Wifi, then do:
    adb shell "dmesg | grep Firmware"

    You should see output with the Firmware version of your Wifi.

    2. If your firmware is different from what other people have already found, then if you can, please package it and attach it to your post. You can do this by:

    adb shell
    su
    cd /system/etc/wifi
    tar cvzf /sdcard/wifi-(your PDA firmware version)-firmware.tar.gz *
    exit
    exit
    (Back in DOS)
    adb pull /sdcard/wifi-(your PDA firmware version)-firmware.tar.gz

    Then upload the tar.gz file.

    Please use the full 5-letter version of your firmware name, for example XXJPY, and not just JPY, or DXJPA, and not just JPA.

    This is what I've found so far:
    DXJPA: Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214.3
    XXJPY: Firmware version = wl0: Nov 16 2010 08:56:21 version 4.218.250.38

    Hi guys,
    two things:

    I wrote a little bash script that extracts the wifi firmware from the tar files you use for flashing with odin (all-in-one and .tar.md5) and parses the fw version.

    h t t p://pastebin.com/cnZmSfLc

    EDIT:
    woops forgot to add a small fix ^^;

    Just extract the firmwares and run the script (as root since it needs to access losetup and mount) from there
    eg

    Code: 
    ~/odin/firmware/2.2.1/ $ ls
I9000XXJPX  I9000XXJPY
~/odin/firmware/2.2.1/ $ ~/findfw.sh

    It'll create a directory /root/wififw and puts the firmwares in there (with tarballs) and it'll dump the version and stores it in FIRMWAREVERSION.version.txt


    Turns out that sometimes only one of those files gets updated....
    I'll look into it in greater detail once i got more firmwares ;)

    EDIT2: added more firmwares

    Appearently the same firmware has been used from JPU to JPY so it'd be interesting to see if the drain occurs on the older firmwares as well. If it does we "just" need to revert it back to JPO fw

    You have to turn off and on your Wifi first. The driver will print the firmware version in dmesg everytime you turn on wifi.

    I know it was long ago but since this is kind of "collection" of wifi drivers of sgs here is the JVH (ginger) driver attached.

    JVH firmware: Firmware version = wl0: Apr 9 2011 23:33:08 version 4.218.248.18
