Hi all, My apologies if this is not the best list to which to send this. I've been trying to get my dell laptop's built-in wireless card to work with my university's wireless network for quite some time now, but nothing I try seems to work. This is on a recent -current: # uname -a FreeBSD prolepsis.urh.uiuc.edu <http://prolepsis.urh.uiuc.edu>; 7.0-CURRENTFreeBSD 7.0-CURRENT #15: Sat Oct 8 01:02:04 UTC 2005 kaduk@prolepsis.urh.uiuc.edu:/usr/obj/usr/src/sys/PROLEPSIS i386 The university's setup, so far as I can tell, is as follows: They have all access points open for association, but do not allow access to the outside world -- when an http page is first requested, the request is intercepted and substituted with a university page that has a link to a kerberos-based authentication, or directions on how to use their vpn client. After authentication, the protocol used is IPSec over UDP. The main point is that the access points are open and running dhcp servers, as confirmed on my iBook (on which I'm writing this message). However, when I try to use the ndis driver on my dell to try to associate with this AP and run dhclient, I get far-from-desireable results. I am using recent (~2 week old) windows xp drivers for my broadcom (4324?) card and I have regenerated bcmwl5_sys.ko after my latest buildworld, using ndisgen(8). The wireless card is listed in pciconf -lv as: ndis0@pci2:3:0: class=3D0x028000 card=3D0x00011028 chip=3D0x432414e4 rev=3D= 0x02 hdr=3D0x00[possibly more off screen] vendor =3D 'Broadcom Corporation' device =3D 'BCM4309 802.11a/b/g Wireless LAN Controller' class =3D 'network' In windows XP, this card is able to successfully associate with the university AP. The bcmwl5_sys.ko module produced by ndisgen seems to load successfully: # kldload bcmwl5_sys warning: KLD '/boot/modules/bcmwl5_sys.ko' is newer than the linker.hintsfi= le 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: 5.1 ndis0: Ethernet address: 00:90:4b:2d:46:ce # I can then scan and see (several) APs: #ifconfig ndis0 up scan SSID BSSID CHAN RATE S:N INT CAPS UIUCnet [bssid1] 1 54M 151:0 100 E [5x ???] WME VEN VEN UIUCnet [bssid2] 6 54M 120:0 100 E [5x ???] WME VEN VEN WME UIUCnet [bssid3] 36 54M 130:0 100 E ??? ??? WME VEN VEN I can then try to associate to one (the same one that my iBook picks by default): # ifconfig ndis0 ssid UIUCnet bssid [bssid1] # ifconfig ndis0 ndis0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLES,MULTICAST> mtu 1500 inet6 fe80::290:4bff:fe2d:46ce%ndis0 prefixlen 64 scopeid 0x4 ether 00:90:4b:2d:46:ce mdeia: IEEE 802.11 Wireless Ethernet autoselect status: no carrier ndis0: failed to get bssid ssid "" channel 1 authmode OPEN privacy OFF txpowmax 100 protmode CTS # (The "failed to get bssid" bit is the console log) The result is the same whether or not I have a dhclient attached to ndis0. Am I doing something stupid, or missing something obvious? I can get more info if necessary. Thanks Ben Kaduk
