    Can you connect to the internal web server in the router to see its
    config screens? Try to connect (or see the router's
    manual as to what is its default IP address).

    Then go to whatever config screen shows the current WAN-side IP address
    assigned to it. That should be an IP address assigned to your account
    from your ISP. Your router is connecting to them so it is what gets the
    dynamically assigned IP address from their DHCP server. If you see an
    APIPA (automatic private IP address) used on the WAN-side of your router
    then it means it isn't getting an IP address from your ISP.

    I never memorize what are the APIPA addresses but I know it when I see
    it. It will not be within the address range for the IP pool assigned by
    a regional registrar to your ISP. It's probably like 169.254.x.x.

    When you cycled the devices, did you do them in the following order?
    - While powered up, push the reset button on the router.
    - Power down the cable modem, router, and computer(s) in any order.
    - Power up just the cable modem. Wait for it to settle.
    - Follow by powering up just the router. Wait for it to settle.
    - Finally power up your computer and log into your account.

    The upstream DHCP server must be available for the downstream device to
    then request an IP address from it. You want the cable modem to come up
    first, then bring up the router so it gets an IP address from the DHCP
    server of your ISP, then power up your computer(s) to get an IP address
    from the DHCP server in your router.

    How old is your router? I found the D-Links start dying or going flaky
    after about 2-3 years. Linksys will last 5-8 years. I haven't used
    Netgear to be familiar with their expected lifetime. There is no fan
    inside the case. The PCB still generates heat so it is dissipated
    through convection. If the holes in the case are blocked (they aren't
    that big to begin with) by dust or even by stacking the devices then
    heat builds up, and [excessive] heat destroys electronics. Don't stack
    anything atop the router. Keep it dusted. Consumer-grade routers do
    die after a few years so it might be time to replace.
