I recently set up a wireless network, consisting of my desktop with a Microsoft MN-720 (Broadcom chipset, using ndiswrapper and mn720-ankh driver (modified bcmwl)), and my laptop with an IBM PCMCIA card (Atheros chipset, madwifi driver). No access point. Since madwifi has problems with ad-hoc mode, and the MN-720 has no master mode, the laptop is set up as an AP and the desktop as a client.

It works just fine, but I have no security. I can't figure out anything to do with WPA (how can I run either of the machines as an Authenticator? Do I even need to?). I tried hostapd, but apparently it only works with Prism chipsets. For WEP (which I'd be content with, as even if it's crackable it would scare off the average kiddy), "iwconfig wlan0 key 1234-5678-abcd-ef01" on the desktop (it works on the laptop) gives:

Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.

Even SSID-hiding on the laptop doesn't seem to work: "iwpriv ath0 hide_ssid 1" claims success, but "iwlist wlan0 scan" on the desktop still shows my SSID.

What can I do?
