Hi, Reporting back after a few days with the patch. The connect and switching=20 between accesspoints work but there are still a few down/up events, about=20 once every two hours but that may have somthing to do with the dhcp cleint. = At the moment, the number of lease renewals match the number of link=20 down/up events. I leave this to the clever folks. When running from the em=20 interface, I do not see any down/up at all and thet net uses the same DCHP=20 server etc. iwi0: link state changed to DOWN iwi0: link state changed to UP iwi0: link state changed to DOWN iwi0: link state changed to UP iwi0: link state changed to DOWN iwi0: link state changed to UP iwi0: link state changed to DOWN iwi0: link state changed to UP iwi0: link state changed to DOWN iwi0: scan stuck iwi0: link state changed to UP /glz --On Tuesday, October 10, 2006 05:04:46 +0200 Max Laier=20 <max@love2party.net> wrote: > On Monday 09 October 2006 20:26, Max Laier wrote: >> On Monday 09 October 2006 19:53, Andrew N.
