HostAP on FreeBSD 4.6-RC2 / Infrastructure vs. Ad-Hoc

Try #2.......missed some output in first posting

Hello all,

I'm trying to get HostAP working as an access point to replace a hardware Access Point so that I can add some additional software capabilities. I have poured over the doc; wicontrol(8), ifconfig(8) and wi(4), many postings from this list and other google searched and have the wireless card running is what appears to be AP mode - see output below. Now when I try to connect from a client, the only way I can "Connect" is to have that client in Ad-Hoc mode. This at least gives me a Connected - BSSID = 02-06-8A-23-CA-B4 but I can't ping the AP PC from the client PC. If I try to have the client PC connect in Infrastructure mode, which I think is the intent of the HostAP software in the first place, I can't get the Client to even report a RF connection.

If I set the AP PC to mode=1 (ad-hoc) they connect and allow traffic to flow, pings at least. Am I missing something really basic here or what? I've included the details of the hardware below along with the output of the important logs (I hope).

AP Host configuration:

mini-tower 1Ghz PIII, FreeBSD 2.6-RC2 version in uname below Linksys WMP11 (PCI card) firmware listed in dmesg below

Client PC

Dell laptop running Windows/2000 (sorry) Linksys WPC11 ver. 3 with linksys provided client software

I've tried a several vendor cards including SMC and Cisco. In my reading, I find that only PRISM is supported and the Linksys cards report using PRISM2.5 chipsets. The firmware loaded in the cards use a different naming convention than that on the Intersil site so I'm not completely sure if it's current, but I just got these through TechData so I'm reasonably sure they are current.

I have not set up the bridging yet as I thought it pointless as I can't even get pings to work in Infrastructure mode. Also, I'm a novice at FreeBSD, or any Unix for that matter so it's completely possible that I've overlooked something vary basic.

Any help, ideas, suggestions, observations or prayers are gratefully accepted!
