zd1211rw driver on Ubuntu 7.04

The PCi USB Wireless dongle GW-US54Mini is working prefectly under Ubuntu 7.04. However, it is only 11Mb/s (i.e. IEEE 802.11b). The dongle is b/g enabled.

I changed the script at “/etc/network/if-pre-up.d/wireless-tools”.

sudo nano /etc/network/if-pre-up.d/wireless-tools

I added the following (red in colour) to the script :

$IWCONFIG “$IFACE” essid “$IF_WIRELESS_ESSID”

$IWCONFIG “$IFACE” commit
fi

I then reboot the system, now the wireless is on 54Mb/s (i.e. IEEE 802.11g).

I am quite more happy with my IBM T23 now.
