Problem:

Notebook MEDION with PRISM 3890 WLAN Card - IEEE 802.11g compliant.

I simply cant get the card working correctly under Windows XP SP1. One
time the device seems to do nothing (no scanning for predefined networks
nor for network to be discovered) and other time it does a very little
bit. However - I played around until Windows suddenly says that a
predefined network is available. Typing the WEP key and hitting Enter
brings me back to the same Dialog. grrrr

Access Point works correctly. I´ve tested the device with other networks
with different environment. Another notebook equipped with an Linksys
PCMCIA WLAN Card works fine with this net.

I´ve tried booting the notebook with a Knoppix-CD. And - wonder, wonder
- it works! I´ve entered data (WEP-Key, channel, SSID etc.) in and:
DHCP, Ping... all is fine. Looking little closer shows me that a new
Firmware is loaded temporarily into the card (RAM-Mode) - version
1.0.4.3. After reboot all is over and gone - and the device works as
used to be: NOT.

I think, loading the new firmware permanently could enable WindowsXP to
work with the card too.

Did somebody flash a new firmware and can share this knowledge? Okay -
there are some HOWTO´s for doing this but I´m not really familiar with
those and I´m not a Linux engineer.

Thanks in advance

AFIAK the firmware needs to be loaded each time the card is powered
up. You can try using the firmware from Knoppix, it should be called
/usr/lib/hotplug/firmware/isl3890. You can also get it from
prism54.org.
I don't use windoze much so I can't tell you where to put the firmware
there, except it's called something.arm.
