Ubuntu Networking :: How To Make Wifi Autoconnect

I have installed Xubuntu 10.4 (Lucid) on a PC at my uncle's. He is the happy owner of a Netgear wg121 wireless usb-adapter.

I have followed the instructions concerning installation of the ndiswrapper here:

The wg is up and running and everything seems to work perfect... except that, when I reeboot and log in, I have to issue the following commands again, to make the network initialize the wep-encrypted connection. If I do not issue these commands, the wifi-part of the Xubuntu network manager (I don't know the exact name of the program) is invisible in the menu or anywhere on the desktop. (It just says no network where the wifi should be appended). But when I issue these commands in a terminal, then the adapter (wg121) opens and connects to the network:

sudo depmod -a
sudo modprobe ndiswrapper
I have tried the command:
sudo ndiswrapper -m

in order to make Xubuntu connect automatically on opening, but no success. When i look through the log it says something about a .conf file, but not which and how, so I'm a bit lost.
