Good to see got his card working. For anyone with an Intel PRO/Wireless 2200BG: the kernel provides the ipw2200 driver but the device will not enumerate unless the non‑free firmware blobs (the ipw2200-*.fw files) are installed under /lib/firmware. The kernel driver docs and Debian packaging show the exact firmware filenames to look for. ipw2200 kernel docs (see firmware notes). firmware package file list. (wireless.docs.kernel.org)

Quick checks to diagnose the common failure (missing firmware, wrong module, or firmware errors): look for ipw2200 in lsmod, and inspect kernel messages for "request_firmware" or "Unable to load firmware". If the firmware is present, try reloading the module and watch dmesg for what the driver requests. Example commands: 

lsmod | grep ipw2200
dmesg | egrep 'ipw2200|firmware'
sudo modprobe -r ipw2200 && sudo modprobe ipw2200
dmesg | tail -n 50

The firmware request/udev flow is described in Ubuntu/Debian kernel/firmware docs. Kernel/firmware explanation. Debian ipw2200 notes. (wiki.ubuntu.com)

How to install the blobs: on Debian add non‑free and install firmware-ipw2x00; on modern Ubuntu the linux-firmware package already contains the ipw2200 files (older Ubuntu releases used linux-firmware-nonfree or a separate firmware package). After installation reinsert the module as above. Example:

# Debian
sudo apt update
sudo apt install firmware-ipw2x00

# Ubuntu (current)
sudo apt update
sudo apt install linux-firmware

See the Debian instructions and Ubuntu package listing for details. (wiki.debian.org)

A note for : the "rt2500" chipset you mentioned is normally Ralink (RT2500), not Realtek, and is handled by the rt2x00 drivers (rt2500pci/rt2x00). Kernel upgrades historically changed driver behavior for several Wi‑Fi chips, so check lspci -nn and modinfo rt2500pci when troubleshooting. If you see repeated "Firmware error detected. Restarting" messages for ipw2200, some firmware versions (e.g. 3.1) were reported unstable; switching to a different firmware build has helped users. rt2x00 background / rt2500 info (driver mapping) and Debian bug reports on ipw2200 firmware versions. (linux.com)

If problems persist, capture and paste the exact dmesg lines that mention ipw2200 or rt2500 — those messages almost always tell you whether the kernel could not find firmware, or if a firmware/driver mismatch is happening.

thanks may guve it a go

ive got a realtek rt2500 based card,worked fine on ubuntu edgy but dapper, feisty,gusty and hoary dont like it
