Only way to ensure that the updates go correctly is hard line.
1. from modem to controller. may require an extra long cable
2. If your able to take apex to computer, may require unpluging everything if you only have 1 EB8
3 If you have/can borrow laptop/extra computer and just plug that into your adapter so they are on same network.
As Jim said the computer does not need internet if you have already downloaded the update. Just a hardwire connection, Especially for the Web pages update
I started with an extra computer/router that I used to reprogram everything after the move. Was plugged into same wireless router as Apex. Since then I've ran a hard line. Was lucky enough that office is over laundry room with drop ceiling and next to fish room. Now Neptune has the nice app out that allows you to edit the programs from Ipad.
Apex Controls everything
Return Pump - Reeflow Gold Hybrid - currently Hammerhead impeller
ATO - Level Loc - which is no longer made Which is a combination of Mechanical float valve, along with 2x floats and solenoid. Hooked up to RO/DI with a pressure switch/solenoid and Autoshutoff valve. In future I will use a BRS Top off doser to pump from the DI side of mixing station, through the Level loc ATO. Then I'll program RODI to only run every few 1-2 weeks to fill up the 75 gallon DI tank.
Biopellet reactor
Ca Reactor - Just brought online last week. Not many corals in tanks at the moment, getting ready for all the frags I bought pre purchased for this weeks swap.
Skimmer - SRO XP5000 EXT
Heat Pump - Using closed loop from hot water heater
Refugium LEDs/ HD cf light
Frag tank Lights 2x AJM 120w LED fixtures
MP60 battery backup
Superfeeder
Although not necessary, plugged into the EB8's I have my 7 AI Sol's, 4 MP40wWs, 2 MP60W's. I just like being able to shut off individual outlet to work on it or when not in use.
I got mine up and working. Even have external access now with the embeded web cam. Kind of nice. Will be able to watch as I feed remotely.
Previously I had used DMZplus mode. Which caused issues with static IP addresses. Had to assign the apex external IP address, so issues with accessing internal. Now doing it the right way with allowed application and opening Port 80. I can access both.
