Hi, all I am using FC4 on a Thinkpad T42. I download the ieee80211 and ipw2200, compile and install succeed. I also put the firmwire to /lib/firmware. And after reboot the system I load the driver with "./load" in ipw2200 src directory, it seems successful, here is the dmesg output: ieee80211_crypt: unregistered algorithm 'NULL' (deinit) ieee80211_crypt: registered algorithm 'NULL' ieee80211_crypt: registered algorithm 'WEP' ieee80211_crypt: registered algorithm 'TKIP' ieee80211_crypt: registered algorithm 'CCMP' ieee80211: 802.11 data/management/control stack, 1.0.3 ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketreno@xxxxxxxxxxxxxxx> ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.6 ipw2200: Copyright(c) 2003-2004 Intel Corporation But I noticed there is no messages for loading the ipw2200 firmware and there's no device eth1, so I can't use the wireless. The command "iwlist scan" list no device eth1, only a LAN device eth0 which can work well with a normal LAN network. Can anyone tell me what's the problem/ Thank you very much, Yours,
