Good afternoon. Immediately after the first switch-on the communication between vac8010f-500V and the panel connection was lost. When power is applied to the panel, the Wifi icon lights on, and after 5-10 seconds it goes off. On FCH is set 46 channel . In CFH is’s also a 46 channel . Actually the same as it was when I bought it. Can you tell me what to do? How to fix? Thanks in advance.
