I've got current from last night: prolepsis# uname -a FreeBSD prolepsis.math.uiuc.edu 7.0-CURRENT FreeBSD 7.0-CURRENT #6: Fri Jul 29 04:30:11 UTC 2005 =20 kaduk@prolepsis.math.uiuc.edu:/usr/obj/usr/src/sys/PROLEPSIS i386 and I'm trying to connect to a friend's ap using wep. My ndis card seems to be recognized just fine: ndis0: <Dell TrueMobile 1400 Dual Band WLAN Mini-PCI Card> mem 0xfaff6000-0xfaff7fff irq 9 at device 3.0 on pci2 ndis0: NDIS API version: 5.0 ndis0: Ethernet address: 00:90:4b:2d:46:ce When I issue an: prolepsis# ifconfig ndis0 inet up ssid 'NetworkXcAe5@r' wepmode on wepkey 0xdeadc0de my interface associates fine, giving me this: prolepsis# ifconfig ndis0 ndis0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::290:4bff:fe2d:46ce%ndis0 prefixlen 64 scopeid 0x3 ether 00:90:4b:2d:46:ce media: IEEE 802.11 Wireless Ethernet autoselect status: associated ssid NetworkXcAe5@r bssid 00:12:17:1d:f7:08 authmode OPEN privacy ON deftxkey UNDEF wepkey 1:40-bit txpowmax 10= 0 but when I run: prolepsis# dhclient ndis0 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 8 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 16 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 11 DHCPDISCOVER on ndis0 to 255.255.255.255 port 67 interval 8 No DHCPOFFERS received.

I know this ap is actually running a dhcp server; it works on darwin. I have read that using ifconfig for wireless (encryption?) is not the way of the future, that I should be using wpa_supplicant, but I haven't been able to succesfully modify a config file to get it to work, and google wasn't very helpful in finding a tutorial or instructions for wpa_supplicant on freebsd. The archives weren't terribly helpful, either -- this is something that would be on freebsd-questions, right? Anyways, if someone could point me to a tutorial for wpa_supplicant, I can check that and see if I get better results, or if you want further information about my configuration, I can get that too. Thanks for putting in all this effort. Ben Kaduk
