Description Volker Stolz 2002-08-15 19:20:01 UTC 
Currently there's no way of setting a preferred SSID for wireless NICs
and asking for DHCP-setup in rc.conf.

You can either configure the NIC manually using e.g.
ifconfig_wi0="... ssid foo..." *or* set ifconfig_wi0 to DHCP and hope
you end up in the correct network.

Fix: 

Add an option to rc.conf which gets queried before setting up the
NIC and which contains the preferred SSID, e.g.

  ifconfig_wi0_ssid="foo"

Modify /etc/rc.network accordingly.

Another, more generic approach would be to have

  wicontrol_wi0="..."

in rc.conf, which would allow for setting *any* parameter
understood by wicontrol, including the SSID.
How-To-Repeat: Use two accesspoints to offer two different networks, enable DHCP in both
and then try setting up your NIC correctly in rc.conf.

The proper way to do this is to use /etc/dhclient-exit-hooks. Take 
a look at the man page for dhclient.conf, and dhclient-script. 
It's not that tough to set up. 

Good luck,
