Linux knocks iBook offline

[Jonathan Hutchins]

Got a strange problem here:  DLink DWL-800AP+, SMC 2435W card in a Winbook, 
and an Airport 11g card in an iBook.

If the iBook goes to sleep/suspend while the Winbook is on line running SuSE 
9.0, it can't connect when it wakes back up.  If the Winbook is shut down, 
the iBook can connect.  If the Winbook is brought back up, the iBook stays 
connected until it goes to sleep again.

I haven't done a definitive test, but we never noticed this when the Winbook 
was running Windows Me.

Any helpful hints where to start looking for the problem?  Tools?
