I have the same issue, except with the Polaris 9650IQ robotic pool cleaner. It always connected just fine (through both my ATT and EERO), and then something changed. Nothing on my network changed. I spent a long time on with support and couldn't get it figured out. They sent me a new control box, same thing so it's not the control box. I should mention it communicates with my phone, it just won't connect to WIFI (even when choosing 2.5ghz and turning off 5ghz on EERO). After another session with support, they were able to get it to connect to my iPads Hotspot but not WIFI. Very strange. In any case, the robotic cleaners have no antenna nor an internal wired/WIFI switch to toggle.
Any suggestions appreciated.
