Apparently there is a firmware problem that inhibits a proper warm
reset. The problem seems to cause the 2.6 kernel a bit of a
consternation as well. A cold reset is always recommended with Netgear's
Prism2USB devices. Removing power forces a proper or at least a decent
reset. Sometimes a hub will power down all the ports when the system
reboots, which is adequate as well.

This seems to work with 2.4 & 2.6 kernels:

On cold boot:
#!/bin/bash
wlanctl-ng [Prism2USBdevice] lnxreq_ifstate ifstate=disable
sleep 1
wlanctl-ng [Prism2USBdevice] lnxreq_ifstate ifstate=enable
...
continue other configuration stuff...

On warm boot:

 1. disable interface with wlanctl-ng $prism2usbdevice lnxreq_ifstate
ifstate=disable
 2. unplug prism2usb device
 3. rmmod prism2_usb module
 4. rmmod p80211 module
 5. plug device back in
 6. wait a sec or 2
 7. modprobe prism2_usb (in case hotplug fails to do it) (might need to
wait a sec after)
 8. disable interface with wlanctl-ng $prism2usbdevice lnxreq_ifstate
ifstate=disable
 9. enable interface with wlanctl-ng $prism2usbdevice lnxreq_ifstate
ifstate=enable
10. continue with configuration stuff.

The above was handled here by shell scripts with ugly tk front ends so
there are buttons to click instead of commandline stuff. It could also
be handled fairly well with a sigle expect script w/ tk front end or
expectk script.

Bad antennae and a new wifi router have retired the prism2 devices I have.
