I have ndiswrapper installed and configured and everything seems to be working correctly. I can run the following commands without a problem and I can scan the wireless networks. /sbin/modprobe ndiswrapper /sbin/iwconfig wlan0 mode Managed /sbin/iwconfig wlan0 key restricted my_key /sbin/iwconfig wlan0 essid my_essid /sbin/dhclient wlan0 I can bring down and bring up the wireless adapter using: /sbin/ifconfig wlan0 [down][up] The problem is I can't get an ip address and the router does not show the client connected. I was using MAC filtering, but I have disabled that to rule it out. DHCP runs on a separate linux box, not on my wireless router. I have a windows machine that connects ok and gets an IP address. My router is a DLink DI624. I'm running FC4 on a HP Compaq nx9110. The wireless card is: 02:02.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03) Any suggestions? Thanks, James
