Regular wifi is working fine and Fusion has been working fine since I set it up at Christmas (of course I was in town). I used a wifi extender then ran a Cat5 wire to into the APEX and I have not had a problem until I left town. I had my wife do the standard IT thing, turn it off and back on but the signal is not coming back. I am just really pissed that a 99 dollar Kindle has built in wifi, a 100 dollar printer has built in wifi, but a $600 dollar controller doesn't! My tank is on the other side of the house from my router so I would need to run a couple hundred feet of cable to hard wire it and I am not usually handy.
I set up a drip of part b (alk has been at 2.5 and ph at 7.8) before I left and planned to monitor the ph and adjust if needed, but I had my wife unplug the aqualifter as I was not sure if I had the failsafe logic and drip set correctly. No big deal but still annoying.
