CM1000 v2 4/5 lights blinking quickly
I recently got a new CM1000v2 modem, to replace the modem/router combo I had been renting from Cox. After hooking it up, the power light blinks green and the three lights below it blink amber while t...
Hi, thanks for the response.
I did unplug the modem for a minute while trying different things. I am assuming that the coax line and connection are good because immediately before activating this modem, the Arris TG1682G that I was (and still am) renting from my ISP worked properly on the same line into the hous, also there are no splitters. When I was talking with the ISP tech we ran through the same steps you mentioned, but the modem remained offline (with the lights continuing to blink as always; the lights begin blinking immediately when it is plugged in to power and that has never changed). Eventually I just asked him to reactivate the Arris for now and it worked immediately. So are you suggesting that line/connection up to the modem could potentially work fine for the Arris but not the Netgear hardware?
If you checked all that and a different modem is working and the CM is not, i would presume the CM modem maybe faulty. Possible the Power adapter tot he CM could be faulty. Something to try with a different same spec power adapter and see. If this still fails, the CM needs to be replaced.
Ok, that makes sense. I did try it (mistakenly) with a different brand new power supply that is 12v 2.5A, like I mentioned earlier. Do you think that would be a sufficient test to know whether the problem is the power supply, or would trying a different 12v 1.5A power supply (which is the spec it came with) be the only way to know for sure?
Again, thanks for your help.
1amp higher isn't going to make a difference, if there power supply doesnt' change the behavior, then the CM needs to be replance. Something to ask NG about to see what your options are.
Ok great, thanks for the confirmation and troubleshooting. I'll get in touch with Netgear directly now.
