dhclient-script, in dhcp-client package as released with Mandriva Linux 2009, would put the network interface down on some circumstances, as part of it"s workings. Coupled with a bug in the kernel wireless stack, when done on wireless interfaces this could cause the wireless association to be lost and never automatically remade. This update fixes dhcp-client to use a better way instead of putting the interface down, working around the wireless stack bug, fixing many cases of the lost association problem.
