Two issues I've seen with my SPA112:
1. If I change the NTP server to "Manual", and try to enter a server URL (such as 0.pool.ntp.org), I get "Invalid NTP Server Address".
2. The SPA112 does not seem to have adjusted automatically to DST, at least judging by the time it shows on the status screen. (I have set the timezone to GMT-05:00 Eastern Time, and checked the "Adjust Clock for Daylight Saving Changes" box.)
