Hi Phil, Thank you for your reply.It's not a good news. If i install my CentOS5.3(2.6.18-128.el5) in a new PC, and plug an other wireless card(mini-pci card with Atheros AR9223 chiset ) into the mother board. Could i get a proper driver and make it work? Now i have done something for that.I installed nidswrapper using the driver in WinXP. The following message will be helpful: ----------------------------------------------------------------- [root at pighead ~]# lspci |grep AR9 03:01.0 Network controller: Atheros Communications Inc.
