Hi,
After browsing the net, I resolved the problem myself.
Here are some facts:
1. The Netgear MA101 WiFi USB adapter comes in two flavors: the original one based on the Intersil firmware and the new Rev. B based on the RFMD firmware. If you bought your MA101 adapter recently (let's say up to one year ago), you probably have the new Rev. B (check the label on the back of the adapter to validate).
2. If you check on the net, you will find (at the very least) three interesting web sites:
a) The Linux-Wlan-Ng Driver project
http://www.linux-wlan.com/linux-wlan
Mandrake 9.2 has the RPM for this driver on the 3rd CD of the Download Edition. Just do a search in Mandrake's Install Software tool with the keyword "prism" and/or "wlan-ng". However, this driver do not support the RFMD firmware (i.e. the new Rev. B adapter), at least not with the latest version of the driver. I do not recommend using this driver.
b) The Atmel Wlan Driver project:
http://atmelwlandriver.sourceforge.net/downloads.html
This is based on the source code provided by Atmel. Atmel is the provider of the RFMD firmware. The latest version of this driver do not support the Intersil firmware (i.e. the original adapter). Also, you need to compile the source code. It is not very complexe to do but you need to make sure that the associated makefile points to the correct kernel source directory by using a symbolic link. I do not recommend using this driver.
c) The BerliOS' AT76C503A Atmel-Based Driver project:
http://at76c503a.berlios.de/#why
Mandrake 9.2 already has this driver (source files and compiled .o lib). Typically, if you plug in your MA101 adapter and reboot, your device will be recognized by Mandrake. However, it is not enough. You need to perform some additional tasks (see below). This driver supports both the Intersil and RFMD firmwares (this is nice...). I recommend using this driver.
The following link provides all the information you need to complete the installation of the MA101 adapter with the BerliOS' AT76C503A Atmel-Based driver:
http://www.jennings.homelinux.net/atmel_92.html
As you will find out in the above link, you need to take special care of the following:
- Install the Wireless RPM so that you can access the iwconfig command. Just do a search in Mandrake's Install Software tool with the keyword "wireless-tools".
- Do not bother about the possibility of having the berlios and the atmel wlan drivers at the same time. By default, it should not be a problem. However, check anyway just in case...
- You need to create the /etc/sysconfig/network-scripts/ifcfg-wlan0 file as indicated.
- You need to modify the /etc/sysconfig/network file by adding the GATEWAYDEV and GATEWAY lines as indicated.
That's it! I hope this "very long" thread will help.
