Here's the deal, Cox. The problem I'm having is a combination of 902MHz ISM ingress and an exceedingly poor gain structure. And probably an "over-subscribed node", but that's just a hunch.
It's not my modem, it's not the wiring in my house (I own an RF network analyzer), it's not downstream signal levels (8.1dB-2.5dBmV), it's not downstream SNR (>37.9dB).
It is the Cox equipment and network.
How do I get in touch with someone at Cox that knows what any of these words mean?
I don't want another "tech" to come out and lop off $50 of Canare F-Conn, calling them "junk" only to have me go back and replace the radio shack grade F-conn's he installed in their place with the wrong sized crimp die. I don't want to have to explain why a directional coupler is different than a power splitter.
As a matter of fact, I don't want -or need- to see the Cox tech at all, because the problem is not on my property.
Who do I need to talk to?
I'm having exactly this same issue, and all I was told was "We're aware of an issue in your area and we hope to have it fixed in the coming weeks." No timeline, no description, no service discount since I can barely use the service... I was also told it has nothing to do with having 500Mbps (requires 32 channels) and wouldn't go away if I dropped to a lower package and used a Docsis 3.0 modem. But I can't really believe anything they say, it seems to all be coordinated to convince me to purchase a "technical support" subscription on top of the terrible service agreement I have.
