Night Hawk CM1200 Downstream Blinking
Off and on my downstream led starts blinking and I loose my internet. I have seen some previous posts but I though I would post my connection. Looks like 24 is an issue. Any guidance is appreciate...
Have the ISP take a look at the information I pointed too.
I finally got a Comcast tech here that knew what he was doing. He put in a ticket and they said that the issue has been resolved. It looks like my power levers are much better and the TV has not paused since. However, I am still seeing uncorrectable errors but no Critical events. Is this normal or do I still have an issue??
I just had Comcast fix an issue where my power levels were -18 instead of -7 or greater. However, I am still seeing uncorrectable errors in the thousands. Is this normal or could the modem be going bad? The pic below is right after I rebooted the modem. Thanks for any insight.
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?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.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.
