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.
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:
tar cvzf /sdcard/wifi-(your PDA firmware version)-firmware.tar.gz *
(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 188.8.131.52
XXJPY: Firmware version = wl0: Nov 16 2010 08:56:21 version 184.108.40.206
