Why would I be lying? my testing methods are legit. Here are my modem levels with the splitter installed and the RTA attenuator removed with the 7610. Well withing spec of my ISP and 7610 operating range. So I had an actual cox tech come out and check my lines and I provided exactly what and how I am testing with data. Why can't you accept not everyone is going to happy with 7610? In end all I am doing is provided my experience with it and wanting to test other modems out to help other users.
I'm not saying you're lying because the modem didn't work for you. I'm saying your test is flawed because not only is your signal an issue if you have to use a splitter or attenuator to drop the signal enough to work, but because you severely nerfed the 7610 by putting on the same line and same splitter as another modem which operates on the same frequencies. So in your very niche and rare case, you didn't get as good results. So to post here saying that the 7610 is worse than what people are using is misleading and flat out lying because your test is completely invalid due to your line quality and testing environment. You can't have a gimped modem and say no it doesn't work it's trash.
But we're not only talking about how much my ping moves by 1ms with X modem vs Y modem. We are talking about functionality of the Netduma here. Sure, lots of modems have low and stable pings. That's their job... But do those modems also work with EVERY feature of the Netduma? NO. And how do I know? Because for months I blamed the Netduma for my ping spikes and internet problems. In the end, only getting rid of all my Arris modems fixed the problem.
+-5 downstream power is the perfect Docsis 3.0 spec and your SNR is pretty low. So not really within spec. Do you know your upstream noise level? Plus I don't believe a word any "tech" that comes to your house says. He can't measure upstream from your house. Dealing with Comcast for 2 years to fix my line shows the people they hire to do house calls know absolutely nothing. Plugging in a signal meter for 1 minute and checking it provides you with a snapshot of information. But what happens when a problem is intermittent? That shows nothing.
I'm done with this conversation. 10+ people have switched from a different modem to the 7610 (even people who swore that their old modem was fine) and have said it was a night and day difference. You switched and because of your poor setup, it did not perform optimally so your test is good? Not how it works lol
