you have noise in the RF line.

 

in the connection table, you can see tons of uncorrectables on your last 3 channels

for the US, there are lot of T3 and couple of T4 timeouts and lot of partial service which means there is noise in the upstream as well.

 

either you have bad cable/splitter or drop or if not, line coming into home itself has noise. you can try fixing the home side by changing cable or connecting to the entry point to try.

If the noise persists everywhere, you will need a tech to fix the noise as that will outside your control.

Ok, Thanks for your suggestion.

 

I have moved my modem to a deferent cable point and directly connected with main input cable without a splitter. Also, cleared the event logs to validate it again.

 

I will keep you posted progress/logs details

    Like vkdelta said, you have a lot of noise/line issues on channels 14-16. 

    If you've moved the modem/router to right where the coax is entering the home and there's no splitters, attenuators, amplifiers in the line, then the ISP needs to check the line.

    I have shared the details after that feel just time wasted to engage NetGear team. I am recommending all buyer to check feedback/answers from other sources before buy any products from NetGear based on their listing level. NetGear sell items with wrong description without their responsibility of the listing description

That's going to show up on any modem. I am recommending all buyer to check feedback/answers from other sources before buy any products from NetGear based on their listing level. NetGear sell items with wrong description without their responsibility of the listing description----Cox changed their requirements. Not netgear. And recently. Its why we always recommend people check with the isp on modem compatiblities. Even cox hasn't changed their own compatiblitiy list but somehow its Netgears faults? Again, it seems like you're blaming the wrong company for an issue they don't have control over.

    Cox technicians again came today as per NetGear suggestion to validate/resolve line noice, he has verified each points and changed points/wire if suspected points. Also, shows my through meter every cable points connection, it was very clear without any noise.

    But I could see still dropping internet, I think this is not supposed device only and NetGear team lying. I am planning to get rented device only from COX, the question is when NetGear accepts their faults and send apologies to customer and upgrade/ return customer change/device.

    Sharing after fix logs again to analyze
