I bit on the move to 19.04. Now, Astroberry WAP does not give an IP address anymore. I know I ensured no config file was altered . Any conf file is in order. Apparently something has changed that now does not allow DHCP to be shared with WLAN.
DHCPCD.CONF looks fine.
WPA_SUPPLICANT.CONF looks fine.
Connect to Astroberry WAP and receive no DHCP. Hmm...
To me, I see too many WLAN0 config options. SSID = astroberryPI is listed as a configuration but nothing show up there. What a challenge. 19.04 is too new.
Rest and fresh review reveals the culprit. The network for VAP is not defined. I tried to use bridge to bridge between vap0 and wlan0 explicitly. Under 16.04 and 18.04, no bridge was required. A bridge requires iptables. Here is my ifconfig output. The virtual network, vap0 , does not have a network defined. Hence, when I connect, I get the universal subnet mask of 255.255.0.0 as generated by "no, you didn't get an IP from your provider. The virtual IP wlan0 is dependent on receiving help from something. Time to build a bridge.
Apparently, vap0 and wlan0 are in conflict with DHCP.CD. Ok. When upgrading from 18.04 to 19.04, the config files pushed contained wlan0 as the recipient of DHCPCD benefits. This overwrote the vap0 settings. I dutifully replaced wlan0 with vap0 to get back to normal. Sysl;og says that isn't working.

File structures for IPV4 and IPV6 are listed as owned by wlan0. Just removing them in a conf file does nothing to clean up the file system, Time for the wrecking ball.
This is a look from another angle. Yep. Failed is bad.
screen resolution suddenly very low,
PHD2 guiding became really, really bad, still works though (related to screen resolution issue???)
Filter change creates hangups almost nightly. NO: nightly
post flip alignment hangs on occasion
and my iMac has to think a lot more for some reason, as documented by the cooling fan coming on, which it didn't need before
and there is more....
