Thanks heaps. I didn't bother to check which version BT4PF came with, just installed your most recent release and it seems to be working as expected.

I say *seems* because I can now see my network, but its essid is unknown (but it should be broadcasting), and there are apparently no other networks using the 5ghz band in my apartment building (which seems odd, but I suppose it's possible). I'll try out the new installation in a more congested area and see what I can see.

Strike that, everything's working. And, lucky me, there's no competition in the 5Ghz band. Thanks for your help.
