My biggest problem is that I can't seem to get DHCP to work with my

fine; I'm about to replace it with something else for 802.11g with a
new WAP.

I would get various beeps when I plugged it in and after it associated,

But I can seem to get things started by issuing the command

  ifconfig wi0 ssid jesterWAP wepmode on wepkey 0x[DELETED]

I can't seem to get a DHCP lease, however:

  # dhclient wi0
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 5
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 13
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 7
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 8
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 13
  DHCPDISCOVER on wi0 to 255.255.255.255 port 67 interval 15
  No DHCPOFFERS received.
  No working leases in persistent database - sleeping.

(Under 4.11, I didn't get any verbose output from dhcpclient.)

I can get a DHCP lease with fxp0, my Ethernet card; also, some 
Macs in the house have no problem getting leases through the

WAP. (The DHCP server is in a separate router, not in the WAP.)

Is there something that's changed under 6.0, or is there just
something I'm forgetting to do? I do plan to get a new card,
but I want to get this working too.


Just about everything about dhclient has changed. The dhclient from ISC 
has been replaced by a complete new development from the OpenBSD team. 
Options that previously worked are nolonger recognized. Among these 
options are the options to configure what wireless network to associate 
with.


Also, added is wpa_supplicant which is used to choose the WLAN to 
connect to.


If there are other WLAN's in your neighbourhood and you have not 
configured wpa_supplicant, it is likely that you associate with the 
wrong network and that network doesn't offer a lease.


One thing to do, mostly for testing: Reset completely your card so it 
does not appear to be associated with any network. When you run dhclient 
and it fails, you should at least be able to see what network it is 
associated with if any.


So, read up on the man-pages, and start over.

Cheers, Erik

DHCP failing with WiFi after 6.0 upgrade

Thanks. I thought this was more appropriate here than on -mobile.
