I had a few hiccups when I first set up my classic. I found that a wireless router just doesn't work on this unit for wifi functionality. After a lot of troubleshooting with members here as well as neptune rep I replaced the net gear router (that is recommended on the neptune site) with a powerline adapter that was recommended here. Had I know all that I would have just gone with the 2016 model because in the end it would have been cheaper. Nonetheless I own it and it has been working great for 2 months or so on the powerline adapter till last night. I was sitting in my living room and I noticed my Apex went through a reboot cycle. Shutting down everything then back up it went. It had never done that before. So I watched to see what could be going on. It did it again a few minutes later. After 4 or 5 reboot I unplugged the eithernet from the powerline adapter and rebooted my home router. I waited a while and the Apex never boot cycled again. So I connected the powerline back up and sure enough it went into the reboot cycle again. It was late so I unplugged the powerline again to make sure it wouldn't reboot once I went to bed. It never did it again. Next morning I reboot my home wifi again. Reconnect the Apex to the powerline adapter and it hasn't done the reboot cycle again. I have no clue why it was doing this. I hadn't changed a thing since the system was set up and finally running without issue. Then for no apparent reason the boot cycle began. Then it was gone. I'd like to prevent that from happening again but I can't replicate it. My concern is burning up some pumps if I'm gone and it does a long series of reboot. I didn't get any alarms by text or email. The system log only showed one loss of power that was never sent as a warning. This issue was fixed by unplugging internet from the system overnight.
