And it does indeed work after all. I picked up a D-Link DWL-650 card and it talked fine on the first try.

The problem was the PCMCIA (16-bit) 3Com AirConnect (3CRWE737A rev.B) card I was using which I thought was "known good" (it was working on my last business trip). It is either now broken or just not speaking the lingo that the Intel PCI card expects. (I even flashed the 3Com, really a Spectrum HR 100mW card, to the latest firmware v2.20 without success.)

The transmit power setting is definitely needed. Without setting the TX power on the Intel card, the D-Link card would only work at 11Mb if it was within 10 *air* feet of the Intel card and not at all past about 25 air feet. It seems to default to lowest power (shows as -15dBm). The D-Link card defaults to full power (15dBm). Once I give the "txpower 30mW" command to the Intel card, I can go over 100 air feet away and maintain 11Mb. That seems to be the only "trick" with this Intel 2011B PCI card.

That all worky... now to get a decent antenna for the Intel card and figure out why the box running HostAP (SMP kernel) is locking up after a lot of re-negotiations. :-(

Thanks for all your help!

Regards,
Mike
