Yeah.
I'm working on a new archive as hypermail as passed it's worth for me.
The new archive is almost complete and will be powered by mhonarc instead.
I like to host my own content rather than use a free-list ..... but as
usual this take time :)

So this doesn't tell me much.
eth0 is connected fine but wlan0 is not.
It seems all the kernel parts are there and wpa_supplicant can scan. I
assume the AP you're trying to connect to is in the above list.
Does dhcpcd-ui disable the AP you're trying to connect to and prompt for
a psk? Can you verify this then appears in /etc/wpa_supplicant.conf (or
where-ever your conf is)?
Thanks
