Activate Wireless Card "Inprocomm IPN2220" (not supported by Kernel) on Ubuntu 7.10

Use "NDIswrapper"
(official solution!)

NDIswrapper can load driver used in Win as a module in Ubuntu.

Standard Steps:
1. download the IPN2220 driver used in Win, (files including inet2220.inf)
2. apt-get install ndiswrapper-utils
3. probemod ndiswrapper
(*or probemod ndiswrapper)
4. dmesg(can see something like "ndiswrapper module version number - loaded")
5. ndiswrapper -i inet2220.inf(install driver)
6. ndiswrapper -l (lower case 'L', list currently installed driver(s))
7.ndiswrapper -m (add alias)
8. modify /etc/modules, insert "ndiswrapper" in the last line
9. reboot

Or directly download GUI version ndiswrapper
