C7800 Dropping ISP connection
Been having a recurring issue with the connection to my ISP randomly dropping. Here are some of the facts: ISP: Wave Broadband Plan: 1GB/10mb Router never loses power Usually comes back within 60...
Thanks for replying. I would like to state that I had another router previously that had the exact same symptoms as this one. Not sure of the exact model but it was an older Nighthawk. Support said I needed to update because it was DOCSIS 3.0 and my gig plan requires DOCSIS 3.1.
I would try another C7800 to see if this problem persists.
IF a different modem did, there could be problems from where you modem is up to the ISP service box. Though I kind of doubt this.
Trying of another C7800 should reveal something.
Hello,
My ISP is sayig the same thing about this router. When they put a Arris 3.1 on line, the SNR look fine. But with this NightHawk C7800. The tech from Atlantic Broadband said something about the SNR is registering 0 downstream on the 25 port downwards yet on the Arris modem he used not issue with the SNR.
My symptoms are peroidic connection drops.
Ex. Monday between 8am - 6pm, every 30 mins. Yet, the next day til today Friday functions fine.
So i really wonder if its the router or the ISP.
This issue have been happening every month at this time (4-10th day).
Right now, its working fine.

Make contact with NG support about an RMA if thats possible.
