Wireless router with a Network Name of 09d44b Wireless encryption key set to: 9d44b Wireless interface (wi0) ssid (network name) 09d44b Wireless encryption key (nwkey) set to 9d44b When the wireless laptop boots, it sends the nwkey in clear text, then goes to 64 bit (or so) encryption. Then transmissions are as theoretically secure as a 5 character key can make them. But, before encryption takes over, the nwkey key is transmitted in clear text and this is Not a Good Thing. Are there any utilites, workarounds or magic available for FreeBSD (4.6 Prerelease at present) that would allow a tunnel to be established before the nwkey is sent... I've had a lot of ideas about how I might do this, but they all rely on the wireless router being a lot smarter than it is. Pointers, links or just plain ideas appreciated.
