Weird, I did all of that and I am getting the same thing. If I start the RPi it will pull IP's for both eth0 and wlan0, as soon as I unplug eth0 both of them go away.
The dhcpcd file has clientid available and duid as #duid so it is not visible. But looking at the syslog trace it looks like it may be doing so anyhow. I can drop a trace on here but it will be a wee bit long. On Wed, Oct 19, 2016 at 1:34 PM, Mike C. <[email protected]> wrote: > > > > Folks, > > I just did a update to a RPi B+.
