Hi there.

I can't get lismet (a wireless sniffer) working with hostap. Kismet aborts with an error message saying that "Set Frequency" is not supported. I/m running SuSE 8.2, kernel 2.4.20, hostap 0.1.1. The PCI wireless card is reported by hostap as an "Intersil Prism 2.5"; "cat /proc/pci" says "Network Controller: Harris Semiconductor Prism 2.5 Wavelan chipset (rev 1)".

Kismet does see the carda nd outputs quite a bit of information about the setup, but it can't get past that error.

Any ideas? Should Kismet work with HostAP? The Kismet docs suggest it should, as do a couple of wireless FAQs, though the latter mention only 2, not 2.5...

Thanks for any help you might be able to offer. If anyone is using hostap and a Prism2.5 card with Kismet, I'd love to see your working Kismet config files.

Regards, K.
