The NIC should be able to do this too. Basically, when you create multiple hostap interfaces, each wlanX interface should get a "new" MAC address. The hardware has a "filter" which can be programmed to allow a set of local addresses; typically what happens is that the last two bits get masked off and so your (four) VAP interfaces get one of those four MAC addresses. The hardware then will happily pass on packets for them. The AR5212 series hardware should support this stuff. Please let me know if this isn't happening. :) >> Are you able to boot things on the older hardware and see what the >> above debugging gives? >> Eg what the attach line is on your amd64 box? > > I think I'll be lucky.

Thanks. Let's first try 32 bit on that system of yours. I hope it's something simple/subtle that I can reproduce locally. Adrian
