You can use any old access point. Wireless bridges are for client-mode i.e. connecting a machine that has wired ethernet only, to another AP.

There are a couple other networks in the area that aren't using any form of wireless security, but they have official-sounding names like ``ASUEMPLOYEE.'' I can connect to them from either computer -- and the connection doesn't go away -- but no DHCP servers will talk to me. I've also tried setting up the laptop in both ibss and ibss-master mode. With ibss-master, ifconfig always reports ``no network.'' However, if I set the iMac up as an ibss-master, I can connect to it from the OpenBSD laptop, get a DHCP lease from it, and ping the iMac. So, it seems that everything works except for sustaining a link from the iMac to the OpenBSD laptop as a hostap for more than several seconds. Surely I must be missing something obvious?

The two computers are less than six feet apart. I can actually connect and (e.g.) ftp to get a file over the network...but only for a few seconds before the link goes dead. Once it lasted for almost half a minute. And that's only if I use a static IP on the iMac; dhcp is never able to get a lease. I've tried everything I can think of -- different channels, 802.11b and 802.11g, different USB ports (including the built-in USB 1.1 port on the back of the laptop), WPA on and off, moving the antenna and computer around, with and without an IP assigned to the interface (using a bridge), DHCP running and not, and probably more. All scenarios give the same symptoms: I can make the connection, but it goes away after a few seconds. I've tried looking in /var/log for clues, but I couldn't find anything.
