Thought I would offer this brief 'how to' on setting this device up. It comes with a USB Wireless G stick and also a base station that you could use to move the USB stick around. The cable on the base is about 8 - 10 feet long. The stick works with or without the base.

This device is a relatively cheap USB Wireless G pen/stick - you can get them for circa US$40 and mine has a great signal strength sitting 6 rooms away (about 200 feet) from an access point. You can get one from an on-line store even (e.g.

It can use 2 different modules depending on the FCC ID:

    K7SF5D7050A - rt2500
    K7SF5D7050B - rt73

The modules are in Portage. However, I couldn't get it to work with the ones included on the Sabayon Linux 3.2 LiveDVD, and lsmod would actually show both the rt2500 and rt73 modules loaded. I tried for about 3 hours to get it to work with the one for my card, which uses the rt73 module.

The modules are also available at

This brief howto covers the rt73 setup.

Download the daily cvs from the above address - rt73-cvs-daily.tar.gz

Extract it:

$ tar xzfvp rt73-cvs-daily.tar.gz

Remove the ones that are in Portage:

# emerge -C rt2500
# emerge -C rt73
# emerge -C rt73-firmware

Remove the leftover modules in your kernel modules directory. Since I am still running 2.6.18-gentoo-4, mine are at:

# rm /lib/modules/2.6.18-gentoo-r4/net/rt2500.ko
# rm /lib/modules/2.6.18-gentoo-r4/net/rt73.ko

Change to the directory you extracted the daily cvs:

# cd rt73*/Module

Make and make install:

# make && make install

Edit the file /etc/modules.d/rt73 and change it to:

#alias usbra? rt73
alias ra0 rt73

Run modules-update force:

# modules-update force

Load the module:

# modprobe rt73

Now, run the command iwconfig and it should show something about rausb0 but it wont have an IP address yet.

# iwconfig

create the net.rausb0 by linking it to net.eth0 in the init.d directory:

# /etc/init.d/net.rausb0 start

And use default settings. If you need to set ESSID or Encryption, you will need to modify /etc/conf.d/wireless

When done, you should be able to run iwconfig and show your connected settings:

# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

vmnet1    no wireless extensions.

vmnet8    no wireless extensions.
