<> The Intersil Corporation Prism 2.5 Wavelan chipset can be found in first-generation IBM ThinkPad R40 notebooks. It won't work with Dapper/Edgy out-of-the-box, because the kernel loads the wrong module---it is best supported by {{{hostap}}}, not {{{orinoco}}}. This can be fixed by adding these lines to {{{/etc/modprobe.d/blacklist}}}: {{{ blacklist orinoco_pci blacklist orinoco blacklist prism2_pci blacklist hermes }}} This should then give you an {{{wifi0}}} and {{{eth1}}} interface which works great with WPA supplicant---see [[WifiDocs/WPAHowTo]]. ---- This solution also helped me make the wireless LAN on my IBM ThinkPad A31p run under Feisty. But only after updating the line in {{{/etc/iftab}}} saying {{{wlan0 mac 00:00:0...}}} with the correct MAC-address the NetworkManager worked automatically. ---- CategoryHardware
