CBR40 - Blinking UPL blue light

My CBR40 started blinking blue light for UPL yesterday.  I shut everything down but can't get the light from blinking.  Had this cable/routerfor 6 month and this is first the light blinking.

    I would have the ISP check there logs and signal to the modem. Give them any info from the CBR40's modem logs as well if needed.

      Most likely you had noise on upstream and when INTERNET LED IS SOLID and US blinks, it typically means it in PARTIAL SERVICE state with one or more UPSTREAMS BEING IMPAIRED.
