	Hi,

	The hardware work sligthly differently, which explain
the difference. The old Wavelan report the values for the last
received packet, whereas the new report the value for the last
packet from the Access Point. As you don't have any Access
Point, no values...
	However, in the wvlan_cs, I did introduce a useful
hack : in ad-hoc mode, /proc/net/wireless report the values
for the first address in the spy list. Of course, you need to
set something in the spy list for this to work...
	So, on each node, just set with "iwspy" the address
of the partner, and you will get what you want in
/proc/net/wireless. You may used the new "wireless.opts" stuff
in 3.1.14 to do that automatically each time you insert the
card...
	Good luck !

	Jean

Question iwspy on WaveLAN operating at other sub-band frequencies

Hi Jean,

Thanks for your helpful suggestion as usual...

If iwspy can be used to "spy" on the link layer status of another card, I assume it works when these cards operate on the same sub-band frequency...

I am wondering if the "new generation" iwspy can be used to "spy" on a card working at another sub-band frequency. Of course, this should be done with "minimal" interruptions to the on-going traffic!?

If this cannot be done in ad-hoc mode, could a mobile host be handed over from one Access Point to another even though these Access Points are using different sub-band frequencies??

If it is possible, does it mean that there is a common control channel (at frequency X) in which Access Point or WaveLAN cards send out and detect other's link layer beacons?? OR am I asking too much for a wireles LAN...

Thanks again for any comments...

Cheers, Jonathan
