It could also have to do with the virtual MAC address changing at times. Anyway, reducing the lease time is appearing to make the situation livable, but it isn't a fix to the issue. I think our lives could be a lot easier if we could figure out how to configure dnsmasq for all of our DNS/DHCP needs (and keep connman out of the way). For newbs, wifi network config via a GUI is a big deal, but we are typically headless. > > Thanks again, > > -- Juliusz > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
