Firmware
Jun Sun's mini-HOWTO explains how to update the firmware from either Windows or Linux. Station Firmware 1.7.4 is recommended if you need support for WPA.
A firmware update package for the wireless function of this adapter is available from Lenovo.
The available firmware version is 1.04.09.00 and is available here. This updates the station firmware to 1.7.4
Note that the IBM site linked above appears to be defunct. Lenovo offers an End-of-Life resource at https://download.lenovo.com/EOL (February, 2022)
Linux WiFi driver
This adapter works with the 'orinoco_pci' driver. In addition the 'hostap' driver can also be used.
The hostap driver supports WPA which the orinoco driver does not. WPA usage might require flashing the NIC's firmware, detailed intructions are available on this page.
Linux Modem driver
The Linux driver from SmartLink supports this device.
Latest version of this driver is 2.9.11.
The modem works with the "ALSA method" which is detailed in the README that
accompanies the SmartLink driver.
Note! Since kernel 2.6.12, there is a new ALSA mixer control "off-hook" which has to be unmuted before the modem can be used, e.g. by running "alsamixer -D hw:1".
You might also try if the newer userspace driver (sl-modem-daemon) works, as it avoids tainting your kernel, and does not require a recompile each time you update your kernel version.
