I just mount my drive like this:

Code: Select all

sudo mount /dev/sda /mnt
Why do you mount /dev/sda ?

what is the output of:

Code: Select all

sudo blkid
I would expect /dev/sda1 that needs to be mounted.

Ernst that's a trivial change in /etc/default/hostapd (effectively DAEMON_CONF is already set to /etc/hostapd/hostapd.conf), it's only relevant if somehow you want to point at another conf file.

PI3 has a unigque MAC and IP.
The not so good news is that the white USB/Ethernet adapter can also be one of these faked adapters.
I have an identical adapter and a similar one (without the USB ports), both have the same mac address.
Both report DM9601 with mac 00:e0:4c:53:44:58

I suspect that I know the cause of your problem but I can not confirm because you masked the mac address.

Interesting, not seen it on Pi, but I do get occasional pauses of about 10s on my x86 laptop (I7, 16GB RAM) when using Chrome. So I don't think it's limited to the Pi, or even the ARM architecture.
Lately I see this occasionally on my Samsung TAB S4.

This all would be avoidable, I guess, I you guys would have been more nice, and just showed me how to properly hardware disconnect the CYW43455, for instance by cutting its wiring! Why cut ?
