New router can't connect to internet

Hi, I got this new router and I want to replace my old one. I connected the cables I was using for my old router, and connected to this new one(this includes 1 white ethernet cable from the wall to port4, another yellow ethernet cable going to powerline adapter for ethernet extension to port 1, another yellow ethernet cable for ont broadband, and coax. But only the port connected to the powerline adapter was blinking).

Since this router has only two ethernet ports, and I need the powerline extension, I tried both ethernet cables but neither gave me internet connection.

The wifi led got lit, and I could connect to it's wifi but it didn't have internet access. The downstream led was blinking. Also the internet led never turned on once. What should I do?

       "5268AC"?  That (almost) answers one of the many questions.  What
    about the others?  Look for "?".

       I doubt that it's suitable.  As I understand it, the co-ax connector
    on an 5268AC is used to connect to some old-style client devices.  The
    co-ax connector on a C6250 is used to connect to the (cable-TV) ISP.
    Not even similar.

     

       Also, because you're not using the "DSL Broadband" port, the cable to
    the "ONT Broadband" port (from your "the wall" I'd guess?) must be your
    connection to your ISP, and a C6250 has no Ethernet WAN/Internet port,
    making it useless as a replacement for a 5268AC.

     

       Nice try, but you seem to be in a square-peg/round-hole situation.
    You want a friend with a plain-old router (with an Ethernet WAN/Internet
    port), not a cable modem+router (with a co-ax WAN/Internet port).

       Why?  What was your "my old one"?  Maker?  Model number?  Who/what is
    your ISP?

       "the wall"?  What's behind your "the wall"?  What's "port4"?

     

    > [...] another yellow ethernet cable for ont broadband, and coax. [...]

     

       "ont"?  "coax" from what to what?  Your "(unspecified) "my old one"
    had a co-ax connection?

     

       Your description seems to include three Ethernet cables.  At least
    one of us is confused.

     

    > Model: C6250|AC1600 WiFi Cable Modem Router


       If I had been using more than two Ethernet ports with my
    (unspecified) "old one", then I might have chosen a different model with
    more Ethernet ports.

       Start with a less confused/confusing problem description?

      Sorry here's a picture of the old router. It's an att uverse 5628ac. The wifi and ethernet would randomly disconnect, and I got a 2 month used router from someone I know, so I'm trying to switch to that one.
