CM2000 Modem: blinking downstream light

Hello. I am using a Nighthawk CM2000 router (which, BTW, is not a listed model for the model dropdown) connected to a Nighthawk AX4 router. Periodically the downstream light on the modem starts blinking white ("modem is scanning for a downstream channel"), and the only way to get it to stop blinking and stay on steadily is to restart the modem. The thing is, though, even while the light is blinking the WiFi connection seems to be unaffected. In fact it is blinking now while I'm online here and typing this message. I even ran a Speedtest.net test while the light was blinking and got some of the fastest speeds I have so far obtained with this router (see below). My question is, can I safely ignore this blinking light, or should I reboot the modem every time it happens? Thanks all!

Re: CM2000 Modem: blinking downstream light

Please post a copy and paste of the modems connection status page.
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.

Re: CM2000 Modem: blinking downstream light

Thank you for the response. Below is a copy of the "modem event log." Is this the info you requested? I have been often in touch with RCN and the modem has been "reprovisioned" several times. Also, I have had (and paid for) three service calls. This first time the tech replaced the connectors at the ends of the cable, and removed one splitter her found in the line. The subsequent visits found the signal to be within spec, and the tech stated that since I had my own modem that was all they could do since they did not support customer-owned modems.

Re: CM2000 Modem: blinking downstream light

Ok. Seen others post having problems with there modems on RCN. I guess RCN believes using 16 channels instead of 32 for 1Gb services. Something most other ISPs use 32 for 1G services.  I don't see a 4th upstream channel locked in. Usually there is 4 on higher speed tiers. Seems like the modem is having problems here on the up. I would ask the ISP to check the upstream channels. Also maybe that the modem is working ok on the up but just on the fringes of it detecting the up as being out of it's expected spec, however still functional. Though all LEDS should be solid ON.

Try this, check the Extended Upstream Transmit Power box and see if this changes anything. If it doesn't un-check the box to disable that. Do a full reboot and test...

I checked the "Extended Upstream Transmit Power" box and it didn't make any difference. The Updtream light still blinks from time to time.

Re: CM2000 Modem: blinking downstream light

I also suffer from the same situation on the Nighthawk CM2000 (Blinking downstream light,) and have tried everything that is offered to correct the problem with no results. I restart the modem and typically within days, if not hours the problem is back. The longest it has stayed solid is about a week. Like others have reported the modem seems to be functioning normally; speed is as expected. So, my question is hopefully simple to answer, should I stop concerning myself with the blinking downstream light, and just let it blink? No need to get technical please, just a straight forward "YES" or "NO" would be greatly appreciated.

Re: CM2000 Modem: blinking downstream light

I would have your ISP check the service line up to the modem. 

Seen others having similar problems with link LEDs blinking and were resolve by the ISP. 

 

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.

Re: CM2000 Modem: blinking downstream light

Thank you for the feedback, but like I said, I have tried and done it all. You name it I've done it. It has become quite obvious that this particular modem has an issue. I have other rather decent modems and none of them suffered from this problem. So, again is their anyone out there that can answer this rather straight forward question: So, with the blinking downstream light, and that the modem is working just fine, should I stop concerning myself over this issue? YES? or NO?

Up to you. 


Personally, if it's working, leave it. 

 

Something else to try. Try a different modem and see if same thing happens. Can be telling.

Re: CM2000 Modem: blinking downstream light

Thank you, that is my thought also, but it is nice to hear an agreement. I did switch back to my previous ASUS, which granted is a little slower, but the issue was not present. When I went back to the Nighthawk the light stayed solid for a week, and then went back to it;s old ways. I'm tired of rebooting it and will just not worry about it anymore. Thanks again for your response.

Keep an eye on things, if you notice something going wrong, get it checked out.
