Have you checked local access on these ports?

Have you entered User Name, Password, Domain Name is correct?

I propose enter DNS addresses also in DHCP Settings. 8.8.8.8 / 8.8.4.4 or any DNS from your ISP.

Firstly check power supply (AC) and his performance. You can use new power supply 12V/1A or 1,5A
