Lights flashing on modem/router

Question

I just purchased and installed the cable modem router above. Is it normal for the upstream LED light to flash continuously? Also, I noticed the 2.4 GHz, 5 GHz and WiFi lights quickly "blink" every few seconds. Just want to make sure all this is normal.

Thanks.

Did to contact your ISP first to ahave them associate it with there system?

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
