I have a two-month-old Apex unit and having numerous problems and I am working with them to resolve. I was originally connected to my WIFI and that's how the system was initially set up. Apex wanted me to download some files for review which they are doing now. However, It would not let me download the files on WIFI, I had to hard wire the unit directly to my router. NOW, the unit will not let me connect back to WIFI. HELP PLEASE.
