setting up a network adapter manually

Hello,

I have the latest driver (I looked yesterday). Does that mean that the device (en1) normally is created when the kernel module is loaded? (result of the kextload command)?

I realized that it is impossible to unload the module when it is loaded once (kextunload command shows an error code). In the systems configuration, the device also disappears if the network has been disconnected one time (instead of network adapter (en1) there is listed network adapter (null)). The device is only up until the wireless connection is broken and does not come up again then.

If there is no other solution I will look for an alternative driver (there are various opensource projects I haven't tried yet). Maybe, the driver itself has bugs. Ralink didn't answer yet.

Non-Apple WLAN hardware isn't treated as airport but like airport handled as ethernet device. en0 is built in ethernet and en1, en2... all the additional network devices. As I said, the system recognizes the ralink device and creates an interface. That is listed in the system preferences and can be configured there (DHCP or manual IP addresses). But if the wireless connection breaks, it disappears from the list (and also if running ifconfig or netstat -i). Once it is disappeared, it isn't listed any more in the system preferences. While it is working, I can copy it as often as I want, but later the device name is replaced there with 'null'. If I want to create a new connection, the wireless adapter does not appear anymore if the connection has been broken one time (just shows 'serial' and 'builtin ethernet'). The ralink device comes with another prefpane for entering WEP-key and to select the network. This part works well when the network connection was broken. I can reconnect there but the device and the wireless connection somehow isn't anymore availlable to be used for IP traffic.
